Öğe Comparison of death and survival cervical necrotizing fasciits cases(Wiley, 2022) Sizer, Bilal; Yilmaz, Umit; Kinis, Vefa; Yorgancilar, Argun EdizBackground Cervical Necrotizing Fasciitis (CNF) is associated with a high mortality rate. The occurrence of mediastinitis with CNF may increase mortality up to 70%. Aims We aimed to identify the differences between surviving and deceased cases. Methods The present study was conducted retrospectively by scanning the files of 16 patients between the ages of 19-71 who were diagnosed with CNF. Patients were divided into two groups as the surviving patient group (SPG) and the deceased patient group (DPG). Both groups were compared in terms of age, gender, Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score, duration of symptom onset to hospital admission, use of antibiotherapy prior to admission, duration of hospitalization, presence of diabetes mellitus (DM), presence of dental etiology, mediastinitis, and respiratory distress at the time of admission. Results Diabetes mellitus was the most common comorbid disease. 5 out of 7 deceased patients had DM. Dental events were the most common etiology. Rapid surgical debridement and airway management was the first treatment method. The most frequently isolated species in the culture was Streptococcus. 6 of 11 patients who developed mediastinitis deceased at the end of the process. Conclusion Dental pathologies mostly play a role in the etiology. It is obvious that dentists, another occupational group that frequently encounters this patient group, have a critical role in this process. Therefore, precise attention should be given to dental problems in patients with diabetes, and hospitalization and initiation of broad-spectrum antibiotherapy should be considered in case of suspicion of deep neck infection.Öğe Effect of caffeic acid phenethyl ester on myringosclerosis development in the tympanic membrane of rat(Springer, 2015) Kinis, Vefa; Ozbay, Musa; Alabalik, Ulas; Gul, Aylin; Yilmaz, Beyhan; Ozkurt, Fazi Emre; Sengul, EnginMyringosclerosis is hyalinization and calcification of certain areas of the tympanic membrane, especially the fibrous lamina propria layer and appears as white sclerotic lesions. Ventilation tube insertion is one of the most performed operations in the pediatric otorhinolaryngology practice to treat chronic otitis media with effusion. Myringosclerosis is a very common sequela of ventilation tube insertion. In this experimental study, our aim was to show the histopathological effects of caffeic acid phenethyl ester on myringosclerosis development in rat tympanic membrane after myringotomy. The rats were randomly categorized into four experimental groups including the comparison group (n = 4), non-treated group (n = 7), the saline (control) group (n = 7), the caffeic acid phenethyl ester group (n = 7). Non-treated group did not receive any treatment for 15 days. Saline (2.5 mL/kg, intraperitoneal) was administered to the third group once a day for 15 days. Fourth group received caffeic acid phenethyl ester intraperitoneally once a day at a dose of 10 mu mol/kg for 15 days. Myringotomy was performed on the right tympanic membrane of all rats except comparison group using a sterile pick with the help of an operating microscope. Histopathological examination of myringosclerosis formation was done by a pathologist under light microscope. In histopathological analysis of groups, the severity of inflammation was milder in caffeic acid phenethyl ester group compared to non-treated and saline groups (p < 0.05). There was less myringosclerotic plaques in caffeic acid phenethyl ester group than in non-treated and saline groups (p < 0.05). TM thickness measurements were very close to each other in non-treated and saline groups. The tympanic membrane thickness of caffeic acid phenethyl ester group was much thinner than the other two groups (p < 0.05). Caffeic acid phenethyl ester decreases inflammation severity and the formation of myringosclerotic plaques. These two effects resulted in thinner tympanic membranes of rats which were treated with caffeic acid phenethyl ester. As a result, caffeic acid phenethyl ester has potential preventive effects on myringosclerosis development after myringotomy and ventilation tube insertion.Öğe The Effect of Corticosteroid Against Streptomycin Ototoxicity(Lippincott Williams & Wilkins, 2013) Kinis, Vefa; Ozbay, Musa; Bakir, Salih; Sengul, Engin; Yorgancilar, Ediz; Keles, Aysenur; Alabalik, UlasThe aim of this experimental study was to determine the possible protective role of corticosteroid in prevention of streptomycin-induced ototoxicity. Twenty-eight adult Wistar albino rats were divided into 4 groups: control (n = 7), streptomycin (n = 7), corticosteroid (n = 7), and streptomycin + corticosteroid (n = 7). Rats were tested with distortion product otoacoustic emissions (DPOAEs) in the beginning and at the end of the study. The animals in all groups were killed under general anesthesia on the 45th day after the last DPOAE measurements. Hearing results were analyzed statistically to determine differences in amplitudes of DPOAE. In addition, the cochleas of each rat were evaluated by histopathologic and immunohistochemical examination. Significant difference was not observed in cochlear hair cells in the control and corticosteroid groups, whereas severe degeneration of hair cells and increased apoptotic cells were observed in the streptomycin group. Moderate degeneration was observed in the streptomycin + corticosteroid group. The hair cells were partially intact. DP-gram of the streptomycin and streptomycin + corticosteroid groups was significantly deteriorated (P < 0.05). The coadministration of steroids with streptomycin, which has a serious ototoxic effect, did not lead to a limitation of this harmful effect.Öğe Effects of caffeic acid phenethyl ester on wound healing of nasal mucosa in the rat: an experimental study(W B Saunders Co-Elsevier Inc, 2014) Kinis, Vefa; Ozbay, Musa; Akdag, Mehmet; Alabalik, Ulas; Gul, Aylin; Yilmaz, Beyhan; Ozkan, HakanPurpose: Wound healing of the nasal mucosa is a highly complex process that restores the anatomical and functional integrity of tissue that has been exposed to trauma. In this experimental study, our aim was to use histopathological examination to investigate the effects of caffeic acid phenethyl ester on the wound healing of rat nasal mucosa after mechanical trauma. Materials and methods: The rats were randomly divided into 3 experimental groups: a non-treated group (n = 7), a control saline group (n = 7) and a caffeic acid phenethyl ester group (n = 7). The non-treated group received no treatment for 15 days. The second group was administered saline (2.5 mL/kg, intraperitoneal) once a day for 15 days. The third group received caffeic acid phenethyl ester intraperitoneally at a dose of 10 mu mol/kg once a day for 15 days. At the beginning of the study, unilateral mechanical nasal trauma was induced on the right nasal mucosa of all rats in the three groups using a brushing technique. Samples were stained using hematoxylin and eosin solution and were examined by a pathologist using a light microscope. Results: The severity of inflammation was milder in the caffeic acid phenethyl ester group compared with that in the non-treated and saline groups (P < 0.05). The subepithelial thickness index was lower in the experimental group (P < 0.05). Goblet cell and ciliated cell loss was substantially reduced in the experimental group compared with the non-treated and saline groups (P <0.05). Conclusions: Caffeic acid phenethyl ester decreases inflammation and the loss of goblet cells and ciliated cells. Therefore, caffeic acid phenethyl ester has potential beneficial effects on the wound healing of nasal mucosa in the rat. (C) 2014 Elsevier Inc.

This experimental study was designed to determine the possible protective effect of HBO therapy on streptomycininduced ototoxicity. Material and Method: Twenty-eight adult Wistar albino rats were divided into four groups: Streptomycin (n= 7), saline (n= 7), HBO (n= 7), and streptomycin plus HBO (n= 7). The HBO administered rats were placed into a large pressure chamber and received 100% oxygene at 2.5 atmosphere absolute for 60 minutes per day in a period of seven days. Rats were tested with DPOAE (Distortion Product Otoacoustic Emissions) in the beginning and the end of study. The animals in all groups were sacrificed under general anesthesia on the seventh day. Biopsy specimens from inner ear were stored for histopathologic examination with hematoxylin and eosin (H& E) under light microscopy. Results: Outer hair cells shown by light microscopic images were mostly preserved in control and HBO group. DPOAE measurements revealed no significant differences between the beginning and the end (p> 0.05). Streptomycin and streptomycin plus HBO treated rats showed loss of hair cells and auditory functions significantly (p< 0.05). Between the groups of streptomycin and streptomycin plus HBO; there was no statistically significance according to the analysis of the histopathological scores and DPgram results (p> 0.05). Discussion: HBO has probably no harmful effect on hair cells. But it seems to be not beneficial in a streptomycin-induced cochlear damage rat model.Öğe EFFECTS OF HYPERBARIC OXYGEN THERAPY ON RAT NASAL MUCOSA(Diagnosis Press Ltd, 2012) Yorgancilar, Ediz; Tunik, Selcuk; Deveci, Engin; Gun, Ramazan; Bakir, Salih; Kinis, Vefa; Ayaz, ErcanThe objective of this study was to evaluate the histopathologic effects of hyperbaric oxygen (HBO) therapy on the rat nasal mucosa. Twelve adult Sprague-Dawley rats, each weighing 180-220 g, were used as experimental animals. The rats were divided into HBO (hyperbaric oxygen) and control group. The rats in the HBO group (n = 6) were placed into a 20-liter HBO chamber (2.5 atmospheres absolute LAW, 25-26 degrees C with 100 % oxygen) for 90 min per day. The rats received hyperbaric oxygen over a period of 7 days. The rats in the control group (n = 6) were not given HBO. All animals were sacrificed at the end of the study, and nasal tissue samples were prepared. The sections were stained with Haematoxylin and Eosin (H-E), Periodic acid-Schiff (PAS) and Trichrome-Masson to observe the under a light microscope. Immunoreactivity of pseudostratified epithelial cells of the nasal mucosa was assessed with E-cadherin expression by immunohistochemical staining. There were significant differences in the average histopathological score between the groups exposed and non-exposed to HBO. In the HBO group, degenerative changes in epithelial cells were observed. The goblet cells showed expansion of their structure. Mononuclear lymphocyte infiltration, dilation of blood vessels, and hemorrhage were observed in considerable areas of connective tissue. In the immunohistochemical evaluation of E-cadherin expression, there were no significant differences between the two groups. Biotechnol. & Biotechnol. Eq. 2012, 26(6), 3394-3396Öğe The Effects of Systemic Use of Nicotine on the Rat Nasal Mucosa: a Histopathologic and Immunohistochemical Study(Soc Chilena Anatomia, 2012) Yorgancilar, Ediz; Tunik, Selcuk; Deveci, Engin; Gun, Ramazan; Bakir, Salih; Kinis, Vefa; Ayaz, ErcanThe objective of this study was to evaluate the histopathologic effects of systemic use of nicotine on the rat nasal mucosa. Twelve adult Sprague-Dawley rats weighing 180-220 g, were used as experimental animals. The rats were divided into Nicotine and control groups. The rats of Nicotine groups (n=6) were administered 2mg/kg Nicotine sulphate for 28 days. The rats of control group (n=6) were only administered 1,5 ml physiologic saline solution subcutaneously for 28 days. All animals were sacrified at the end of the study and nasal tissue samples were removed and prepared for histologic examination. The sections were stained with Hematoxylin and Eosin (H-E) and Periodic acid-Schiff(PAS) and Trichrome-Masson were observed under light microscope. E-cadherin immunreactivity of pseudostrafied epithelial cells of nasal mucosa was assessed by immunohistochemical staining. There were significant differences in average histopathological score between the groups treated and non-treated to nicotine. In nicotine group, degenerative change of epithelial cells and hypertrophy of goblet cells were observed. Leukocytes infiltration was observed in significant areas of connective tissue. E-cadherin expression was significantly decreased in epithelial cells of the nasal mucosa of Nicotine group.Öğe Evaluation of Hyperactivity, Attention Deficit, and Impulsivity Before and After Adenoidectomy/Adenotonsillectomy Surgery(Lippincott Williams & Wilkins, 2013) Ayral, Muhammed; Baylan, Muzeyyen Yildirim; Kinis, Vefa; Bez, Yasin; Bakir, Salih; Ozbay, Musa; Yorgancilar, EdizObjective: The objective of this study was to determine the severity of attention deficit, hyperactivity, and impulsivity symptoms in patients with obstructive airway problems scheduled to undergo adenoidectomy or adenotonsillectomy operation. The effects of the surgical treatment on these symptoms will also be investigated in a case-control design. Methods: This prospective study included 63 patients (29 girls, 34 boys) who were operated on at the Department of Otorhinolaryngology, Dicle University Medical School, between January 2010 and May 2011 because of obstructive symptoms caused by adenoid or adenotonsillar hypertrophy. The age range of the patients was between 4 and 13 years. The control group consisted of 33 (17 girls, 16 boys) healthy children. Results: Among the patients, 15 children underwent adenoidectomy because of adenoid hypertrophy; 13 patients had adenotonsillectomy because of adenotonsillar hypertrophy, and the remaining patients underwent adenotonsillectomy related with chronic or recurrent tonsillitis with adenoid hypertrophy. Based on the preoperative data, statistically significant difference was observed between the patient and control groups. The patients' attention deficit, hyperactivity, and impulsivity symptoms preoperatively and postoperatively have shown statistically significant differences. Conclusions: Attention deficit, hyperactivity, and impulsivity symptoms were common among the children who show signs of airway obstruction due to adenotonsillar hypertrophy. Adenoidectomy or adenotonsillectomy operations were both observed to be associated with improvement in these symptoms.Öğe Histological evaluation of rat larynx in experimental polycystic ovary syndrome model(Springer, 2012) Deveci, Hande Senem; Deveci, Ildem; Habesoglu, Mehmet; Surmeli, Mehmet; Kinis, Vefa; Eriman, Murat; Gunes, PembegulThis study aimed at studying the histopathological effects of hyperandrogenemia and estrogen deficiency on larynx mucosa in experimentally designed polycystic ovary syndrome of female rats. Two groups of experimental polycystic ovary syndrome model were composed in healthy female rats by per oral letrozole administration of for 21 and 42 days. Also a control group which only took vehicle (saline) for 42 days was designed. Laryngeal mucosa and ovaries of all animals were examined histopathologically by light microscopy and the serum hormone levels were analyzed using a solid-phase, two-site chemiluminescent enzyme immunometric assay. Statistically significant edema, vascular engorgement, inflammation, cilia loss and differentiation of goblet cell distribution were observed when the control group and study groups were compared (p < 0.01). In serum hormonal analysis there was a significant increase in levels of androgens and decrease in levels of estrogens. In addition, polycystic appearance of ovaries in letrozole-administered groups and normal appearance of ovaries in control group have been proven histopathologically. Polycystic ovary syndrome which causes estrogen deficiency and hyperandrogenemia in fertile ages resulted in histopathological changes in laryngeal mucosa.Öğe Histopathologic results of long-term sildenafil administration on rat inner ear(W B Saunders Co-Elsevier Inc, 2012) Bakir, Salih; Firat, Ugur; Gun, Ramazan; Bozkurt, Yasar; Yorgancilar, Ediz; Kinis, Vefa; Penbegül, NecmettinObjectives: Sildenafil, a selective inhibitor of phosphodiesterase type 5, is widely used for the treatment of erectile dysfunction. Although cochlear effects of phosphodiesterase type 5 inhibitors remain still unclear because of inadequate data, some evidence that recently emerged indicates that these medications may be responsible for hearing impairment. In the present study, we aimed to examine the histopathologic effects of long-term sildenafil use on the cochlea in a rat model. Methods: The study was performed with adult male Wistar albino rats. The control group was fed on standard laboratory diet. The study group was applied orally with sildenafil therapy, 1.5 mg/kg once a day for 45 days. Rats were anesthetized and decapitated. Each temporal bone was dissected, and the cochleas were removed en bloc. The inner-ear biopsy specimens were examined histologically with hematoxylin and eosin and caspase 3 immunoreaction under light microscopy. Results: Hematoxylin and eosin staining showed no distinctive difference between the control group and the sildenafil group. With immunohistochemical examination, caspase 3 immunoreactivity was observed in the sildenafil group. In the control group, caspase 3 immunoreactivity was not observed. Conclusions: The caspase 3 immunoreactivity in the sildenafil group was strongly associated with an increase in apoptotic events in the cochlea. Long-term use of sildenafil can cause hearing impairment through increased apoptosis. (c) 2012 Elsevier Inc. All rights reserved.Öğe Is there Epithelial Tissue in Bone Pate? A Histopathology Study(Mediterranean Soc Otology & Audiology, 2012) Yorgancilar, Ediz; Firat, Ugur; Alabalik, Ulas; Gun, Ramazan; Yildirim, Muzeyyen; Bakir, Salih; Kinis, VefaObjectives: To evaluate the histology of bone pate collected during mastoidectomy in chronic suppurative otitis media (CSOM) patients with or without cholesteatoma. Study Design: Prospective controlled study. Materials and Methods: The study recruited 32 patients (15 males, 17 females; average age 25.3 (range 19-56 years) who underwent mastoidectomy for CSOM: 16 with cholesteatomas (group I) and 16 controls with granulation or polyp tissue (group II). In all patients, bone pate was collected separately from the mastoid cortex (Level 1), subcortical air cells (Level 2), and just before the antrum mastoideum (Level 3). All samples were stained with hematoxylin-eosin (H&E) and immunochemically with a monoclonal antibody against epithelial membrane antigen (EMA). The presence of squamous epithelium in the bone pate was examined under a light microscope. Results: In Group I, we detected epithelial cells in the bone pate samples obtained from the mastoid subcortex (two of 16 patients) and antrum (four of 16 patients) levels. However, no epithelial cells were observed in bone pate from the mastoid cortex. In the controls (group II), no epithelial tissue was observed in any sample from any level. Conclusions: Epithelial cells can inoculate bone pate collected from the subcortical and antral areas of the mastoid bone in patients with cholesteatomatous CSOM. To prevent epithelial cell inoculation, we recommended that bone pate be collected only from the cortical bone of the mastoid.Öğe Long-term Follow-up Results of the Patients Suffering from Sudden Hearing Loss(Mediterranean Soc Otology & Audiology, 2013) Akdag, Mehmet; Gul, Aylin; Bakir, Salih; Gun, Ramazan; Ozbay, Musa; Kinis, Vefa; Yorgancilar, EdizObjective: The aim of this follow-up study was to evaluate the time-dependent course of hearing recovery in idiopathic SHL patients. Materials and Methods: Forty-four unilateral idiopathic SHL patients treated with the same standard regimen for 10 days were retrospectively reviewed, then they were invited to return to our hospital for their last visit and last audiogram during the study period. Gender, age, duration and severity of hearing loss, the shape of the audiogram and, the presence of tinnitus were evaluated. Thus, the long-term audiometric data, the final hearing outcome and, the rates of hearing recovery was obtained. Results: There was a significant difference in the degree of hearing loss and the rates of hearing recovery between early stage and long-term follow-up (p<0,001). The most common audiogram shape was flat. Hearing was significantly worse in SHL patients with tinnitus compared to SHL patients without tinnitus (p<0,001). Conclusion: Our results revealed that even if the failure of an initial 10-day course of treatment, a delayed recovery continues and there may still be enough time for complete recovery except profound SHL. Tinnitus on presentation with SHL and profound SHL has been identified as a negative prognostic indicator.Öğe Management of Orbital Complications of Sinusitis in Pediatric Patients(Lippincott Williams & Wilkins, 2013) Kinis, Vefa; Ozbay, Musa; Bakir, Salih; Yorgancilar, Ediz; Gun, Ramazan; Akdag, Mehmet; Sahin, MuhammedThe most common reason of orbital infections is sinusitis. Orbital complications of sinusitis are mostly seen in children. Loss of vision and intracranial infections are among the complications of sinusitis. Prompt diagnosis and treatment is very important in the management of orbital complications. The orbital complication can be in the form of cellulitis or abscess. A retrospective review of 26 pediatric patients with orbital complications due to sinusitis was presented in this study. Of 26 patients, there were 13 cases of preseptal cellulitis, 2 cases of orbital cellulitis, and 11 cases of subperiosteal abscess. We grouped the preseptal and orbital cellulites in one category and the subperiosteal abscess in the other. All patients in the cellulitis group recovered by medical treatment. All the patients were treated by surgical drainage. Early diagnosis and appropriate treatment method are vital for the treatment of orbital complications secondary to sinusitis.Öğe Mental health and quality of life in patients with chronic otitis media(Springer, 2013) Bakir, Salih; Kinis, Vefa; Bez, Yasin; Gun, Ramazan; Yorgancilar, Ediz; Ozbay, Musa; Aguloglu, BulentThe present study focused on the comparison of mental health and quality of life (QoL) between chronic otitis media (COM) patients and the hearing population. The patients with chronic otitis media and healthy control group were enrolled in the study. The duration and severity of the auditory impairment were recorded. In addition to hearing loss (HL), the findings of each patient's other ear disorders (ear discharge and tinnitus) were also recorded. In both the groups, psychological symptom profile and health-related QoL were evaluated and compared using a sociodemographic questionnaire, the Symptom Check List 90-Revised Form (SCL-90-R), and the Short Form-36 (SF-36). According to SCL-90-R, somatization (p < 0.001), interpersonal sensitivity (p < 0.001), depression (p < 0.001), phobic anxiety (p < 0.001), and other subscores, and also global severity index score (p < 0.001) were significantly high in patient group when compared to the control group. The patients with COM reported significantly lower levels of QoL in terms of physical role difficulty (p < 0.001), general health perception (p < 0.004), social functioning (p < 0.001), and mental health (p < 0.017) than those of control subjects. Our results indicated that COM patients with mild or moderate HL have poorer life quality and higher psychological problems. Psychological well being should be also considered in assessment of COM patients in addition to the clinical evaluation and audiological tests.Öğe Neck Masses: Retrospective Analysis of 981 Cases(Ortadogu Ad Pres & Publ Co, 2012) Tanriverdi, M. Halis; Bakir, Salih; Kinis, Vefa; Ozbay, Musa; Toprak, S. Ferit; Firat, UgurObjective: The purpose of this study was to determine and discuss the diagnostic distribution, clinical behaviors and histopathological features of neck masses of patients who were followed-up in our department. Material and Methods: A total number of 981 patients with neck masses, who attended the Department of Ear-Nose-Throat in Dicle University Medical School, between 1992 and 2010, were analyzed retrospectively. Results: Among the 981 cases, 485 (49.5%) had a mass with neoplastic origin, whereas 383 (39%) had inflammatory and 113(11.5%) had congenital neck masses. Approximately 69% of the neoplastic masses were malignant and 31% were benign in nature. The mean ages were 28.26 +/- 7.69 and 11.45 +/- 4.08 years in patients with inflammatory and congenital masses, respectively. The mean age of the patients diagnosed with benign neck masses was 35.5 +/- 5.80 years while the mean age of the patients with malignant masses was 49.22 +/- 11.68 years. Conclusion: Neoplastic masses seem to be the most frequent cause of neck masses. Neck masses, especially in adults should be considered malignant until proven to be benign. In addition, biopsy specimens should not be obtained before a detailed ear, nose and throat examination of the patient.Öğe Neonatal respiratory distress(Galenos Yayincilik, 2012) Bakir, Salih; Kinis, Vefa; Ozbay, Musa; Yolbas, Ilyas; Keles, Ayse Nur[Abstract Not Available]Öğe Outcomes of revision external dacryocystorhinostomy and nasal intubation by bicanalicular silicone tubing under endonasal endoscopic guidance(Ijo Press, 2012) Ari, Seyhmus; Cingu, Abdullah Kursat; Sahin, Alparslan; Gun, Ramazan; Kinis, Vefa; Caca, IhsanAIM: To evaluate the long-term treatment outcomes in patients who underwent revision of external dacryocystorhinostomy (DCR) and nasal intubation by bicanalicular silicone tubing (BSTI) under endonasal endoscopic guidance. METHODS: Data from 28 patients with recurrent dacryocystitis were retrospectively reviewed. Revision external DCR and bicanalicular nasal intubation by silicone tubing under endonasal endoscopic guidance was performed in 28 eyes of 28 patients. The patients were evaluated with respect to the reason of recurrence, time to recurrence, time to revision, duration of follow-up and surgical success. RESULTS: Endoscopic endonasal examination detected an osteotomy-side obstruction by the excessive granulation tissue in 24 patients (86%), nasal septal deviation in three patients (10%) and nasal polyp in one patient (4%). Recurrence occurred after a mean duration of 5.3 +/- 3.7 months following the first operation. The mean time between the first DCR operation and the revision DCR was 11.5 +/- 9.3 months. After a mean follow-up of 14.9 +/- 7.8 months, the rate of anatomic success alone was 85% (24/28); the rate of subjective success was 78% (22/28). CONCLUSION: Revision external DCR and bicanalicular nasal intubation by silicone tubing under endonasal endoscopic guidance can be recommended in patients with recurrent dacryocystitis as a surgical approach that achieves satisfactory objective and subjective success rates.Öğe Patients With Congenital Choanal Atresia Treated by Transnasal Endoscopic Surgery(Lippincott Williams & Wilkins, 2014) Kinis, Vefa; Ozbay, Musa; Akdag, Mehmet; Cetin, Muzeyyen; Gul, Aylin; Yilmaz, Beyhan; Sengul, EnginCongenital choanal atresia (CCA) is defined as a congenital failure in the development of communication between the nasal cavity and nasopharynx in newborns. It is the most common congenital anomaly of nose. Most of the patients presented with unilateral CCA. Neonates with bilateral CCA have severe respiratory distress after birth. Airway control with orotracheal intubation should be done immediately to save the life of neonate with bilateral CCA. After airway control, surgery should be performed as soon as possible. The aim of surgery is to create a patent nasal passage and to prevent restenosis with minimal morbidity. Transnasal endoscopic surgery of CCA has become the most popular treatment method. The retrospective review of 33 patients with CCA was presented in this study. The patients who were diagnosed at the neonate period and operated on in 6 months after birth were grouped as I (neonate). The patients who were diagnosed 6 months after birth were grouped as II (child-young adult). All patients were treated by transnasal endoscopic surgery. Stent were put in all patients to prevent restenosis. Although the restenosis rate was higher in group I (53.8%) than in group II (23.1%), it did not cause a statistically significant difference. Overall success rate of our surgical approach was 61.5%. Despite the surgical developments and many treatment modalities, restenosis is still the most challenging problem in CCA.Öğe The protective role of caffeic acid phenethyl ester against streptomycin ototoxicity(W B Saunders Co-Elsevier Inc, 2013) Bakir, Salih; Ozbay, Musa; Gun, Ramazan; Yorgancilar, Ediz; Kinis, Vefa; Keles, Aysenur; Abakay, AbdurrahmanObjective: The aim of this experimental study was to investigate the efficacy of caffeic acid phenethyl ester (CAPE) in the prevention of streptomycin-induced ototoxicity. Materials and Methods: Thirty-two adult Wistar albino rats were divided into 4 groups: control (n = 8), streptomycin (n = 8), CAPE (n = 8), and streptomycin + CAPE (n = 8). Rats were tested with distortion product otoacoustic emissions (DPOAEs) before drug administration. The animals in all groups were killed under general anesthesia on the 45th day following last DPOAE measurements. Hearing results were analyzed statistically to determine differences in amplitudes of DPOA E. Also, the cochleas of each rat were evaluated by histopathological and immunohistochemical examination. Results: Significant difference was not observed in cochlear hair cells in the control and CAPE groups. In the streptomycin group, severe degeneration of hair cells and increased apoptotic cells were observed. In the streptomycin + CAPE group, although some deteriorations were observed, hair cells were mostly preserved. The DPgram of the streptomycin and streptomycin + CAPE groups was significantly deteriorated (P < .05). The analysis of the DPgram results revealed statistically significant differences between the groups of streptomycin and streptomycin + CAPE (P < .05). Conclusions: Caffeic acid phenethyl ester treatment attenuated hair cells injury in the inner ear, possibly via its antioxidant effect. Prophylactic administration of CAPE for streptomycin ototoxicity ameliorated hearing deterioration in rats. (C) 2013 Elsevier Inc.

The intraoperative findings and temporal bone CT results of 350 patients who were diagnosed with CSOM between September 1, 2010, and June 1, 2013, were compared. Comparison parameters were as follows: the presence of cholesteatoma, erosion of the outer ear bone canal, erosion of the middle ear chain, erosion of the dural plate, erosion of the lateral semicircular canal, erosion of the sigmoid sinus wall, and dehiscence of the facial canal. The contribution of CT was limited in showing the outer ear canal destruction, dural plate destruction, facial canal destruction, lateral semicircular canal destruction, and destruction of the sigmoid sinus wall. However, CTwas more sensitive in detecting cholesteatoma and erosion of the ossicular chain. These results indicate that preoperative CT of patients with CSOM serves as an important guide for otolaryngologists, although there are limitations in the evaluation of the CT results.
