Öğe Complications of chronic suppurative otitis media: a retrospective review(Springer, 2013) Yorgancilar, E.; Yildirim, M.; Gun, R.; Bakir, S.; Tekin, R.; Gocmez, C.; Meric, F.The purpose of this study was to review our patients with complications of chronic suppurative otitis media (CSOM) and compare with literature. This retrospective study was performed over 10 years in our tertiary referral university hospital. During this period 4,630 patients with CSOM were admitted to the department and 906 patients underwent a surgery. From the records of the 4,630 patients, 121 patients (2.6%) with complications were identified. Of the 906 CSOM patients that underwent a surgery, 511 had cholesteatoma, and 395 had granulation and/or polyp tissue. Ninety-four of 511 (18.4%) patients with cholesteatoma and 27 of 395 (6.8%) patients with granulation and/or polyp tissue had a complication. Of the 121 complicated CSOM patients, 57 extracranial (47.1%) and 37 intracranial (30.6%). Multiple combined complications were occurred in 27 (22.3%) patients. The mastoid abscess was the commonest extracranial complication (28.3%); it was followed by labyrinthitis (9%), facial nerve paralysis (8.4%), and Bezold's abscess (1.3%). The most common intracranial complication was lateral sinus thrombophlebitis (19.5%), followed by perisigmoid sinus abscess (13.5%), meningitis (9%), brain abscess (6.5%), and extradural abscess (4.5%). Most frequent intraoperative finding of complicated CSOM patients was cholesteatoma, with the exception of patients with facial nerve paralysis. There was no mortality in any of our patients. The additional morbidities were recorded in 25 patients (20.6%). In this study, we emphasize the importance of an accurate and early diagnosis, followed by adequate surgical therapy and a multidisciplinary approach.Öğe Effects of N-acetyl-cysteine and acetylsalicylic acid on the tonsil bacterial biofilm tissues by light and electron microscopy(Verduci Publisher, 2014) Bulut, F.; Meric, F.; Yorgancilar, E.; Nergiz, Y.; Akkus, M.; Nergiz, S.; Nasir, Y.OBJECTIVE: The present study aimed to investigate the effects of the bacterial biofilm formation on the tonsil surface exposed N-acetyl-cysteine (NAC) and acetylsalicylic acid (ASA) of patients undergoing tonsillectomy by light and electron microscopy. The general process of biofilm formation comprises adhesion of free-living or planktonic bacteria to a surface, which subsequently develop into microcolonies and form a biofilm. Based on studies that have shown the presence of biofilms in common sites of chronic infections, it has become clear that bacteria may persist on mucosal surfaces through formation of biofilms. PATIENTS AND METHODS: Ten patients between 4 and 39 years of age (mean, 11.9 +/- 11.2 years). In all cases, periodic acide Schiff (PAS) staining was found to be an accurate predictor of the presence or absence of biofilm using light microscopy as a control standard. Therapeutic doses of NAC and ASA were identificated as the effective on the tonsil bacterial biofilm using light and electron microscopy. RESULTS: Biofilm formation was detected on all samples. Tonsils removed from patients with ASA-10 had showed higher-grade inhibitory effect at the biofilm formation than the other group (p <= 0.0001). The correlation was found between drug dose and decrease at the biofilm formation. CONCLUSIONS: In chronic or recurrent tonsillitis patients, decrease on the tonsils surface biofilm formation may be associated with ASA dose. Whether effect on the tonsils surface biofilm formation of other agent have a role is not known.Öğe Schwannoma of the nasal tip: case report and short review of literature(Galenos Yayincilik, 2009) Yildirim, M.; Yorgancilar, E.; Bulut, F.; Meric, F.; Topcu, I.A case of nasal tip Schwannoma is presented in this paper. Schwannoma is usually a benign neoplasm which is composed of Schwann cells. A 14-year-old boy had suffered from progressive swelling of the nasal tip over 4 months. Computed tomography showed a large soft tissue density in the nasal tip. The mass was resected using an external rhinoplasty approach, and the pathologic diagnosis was Schwannoma. Here, we present this case and discuss the clinical and pathological aspects of Schwannoma arising in the nasal tip.Öğe Temporal bone erosion in patients with chronic suppurative otitis media(Royal Belgian Soc Ear, Nose, Throat, Head & Neck Surgery, 2013) Yorgancilar, E.; Akkus, Z.; Gun, R.; Yildirim, M.; Bakir, S.; Kinis, V.; Meric, F.Temporal bone erosion in patients with chronic suppurative otitis media. Objectives: To analyse temporal bone erosion sites (including scutum, labyrinth, facial canal, mastoid tegmen, posterior fossa dural plate and sigmoid sinus plate) in patients with chronic suppurative otitis media (CSOM). Methodology: Retrospective case review in a tertiary referral centre. Medical records were reviewed from 905 patients (121 complicated; 784 non-complicated) who received a mastoidectomy as a minimum intervention for the treatment of CS OM. Results: All types of temporal bone erosion were found to be more frequent in patients with complicated CSOM. Erosion in the scutum, mastoid tegmen, posterior fossa dural plate and labyrinth was observed significantly more frequently in complicated-CSOM patients with a cholesteatoma. Granulation/polyp tissue invaded the sigmoid sinus and facial canal at a rate similar to cholesteatoma. Conclusions: Our study demonstrates that bone erosion is more frequent in complicated-CSOM patients. Temporal bone erosion can be seen in both cholesteatomatous and non-cholesteatomatous CSOM patients. Granulation/polyp tissue was as important as cholesteatoma in the erosion of the facial canal and sigmoid sinus plate.
