Öğe A clinical study on ankylosis of the temporomandibular joint(Churchill Livingstone, 2006) Erol, B; Tanrikulu, R; Görgün, BIntroduction: Restoration of normal function and jaw movement in patients with temporomandibular joint (TMJ) ankylosis is difficult. Various techniques have been defined for the treatment of the condition. Patients: This study is based on the pre-, intra- and post-operative evaluation of 78 TMJ operations in 59 patients who were treated for TMJ ankylosis between 1985 and 2002. Methods: The patients in this study were evaluated with regard to age, gender, aetiology of ankylosis, ankylosis type/classification, existing facial asymmetry, maximal pre- and post-operative mouth opening, the arthroplasty methods (gap and interpositional arthroplasty) including complications and recurrence of ankylosis. Results: Falls represented the most widespread aetiological factor (85%), and women constituted the group with the highest incidence of ankylosis (61%). Forty cases were unilateral (68%) and 19 bilateral (32%); 82% (64 joints) were of the bony type. Gap arthroplasty was applied in 34 of the 59 cases (58%) and interpositional arthroplasty in the remaining 25 (42%). Pre- and post-operative mean mouth opening were 3.5 +/- 1.7 and 30.7 +/- 3.0 mm, respectively. Re-ankylosis was noted in 5%. Conclusion: In addition to radical and sufficient resection of the ankylosed bone, early postoperative exercises, appropriate physiotherapy and close follow-up of the patient play an important role in the prevention of post-operative adhesions and re-ankylosis. (c) 2005 European Association for Cranio-Maxillofacial SurgeryÖğe Comparison of computed tomography with conventional radiography for midfacial fractures(British Inst Radiology, 2001) Tanrikulu, R; Erol, BObjective: To compare the clinical effectiveness of computed tomography (CT) with conventional radiography in midfacial fractures. Methods: The conventional radiographs (CM) and CT scans of 40 consecutive patients with complex midfacial fractures were assessed independently by two examiners, The number and site of fractures of the orbit, zygoma and maxilla were compared by the Wilcoxon Matched Pairs Signed Rank test. The best method for classification of the fracture was determined. Results: Coronal CT (CCT) proved superior in the diagnosis of orbital fractures (P<0.001). There was no significant difference between any of the imaging methods for fractures of the zygoma. Axial CT (ACT) tvas the most effective method in imaging of maxillary fractures (BCT-CM; P<0.001? ACT-CCT; P<0.01). CCT was the most useful in classification of orbital and maxillary fractrue. Conclusion: CCT is superior to CM for the assessment of complex, midface fractures.Öğe Congenital alveolar synechiae -: a case report(Nature Publishing Group, 2005) Tanrikulu, R; Erol, B; Görgün, B; Ilhan, ÖCongenital alveolar synechiae is rarely seen as an isolated disease. It is generally observed together with various syndromes such as Van der Woude and cleft palate lateral alveolar synechiae syndrome, and is concomitant with other anomalies in the maxillofacial or other regions of the body. Prior to this case report, eight cases of isolated congenital alveolar synechiae have been reported. This paper reports a case of isolated congenital alveolar synechiae in a 10-month-old baby girl. The report concentrates on the clinical features of isolated congenital alveolar synechiae, the likely aetiological causes and the treatment.Öğe The contribution to success of various methods of treatment of temporomandibular joint ankylosis -: (a statistical study containing 24 cases)(Turkish J Pediatrics, 2005) Tanrikulu, R; Erol, B; Görgün, B; Söker, MTemporomandibular joint (TMJ) ankylosis is an important joint disorder which, in addition to emerging through trauma, can also arise as a result of local and systemic infections. TMJ ankylosis which develops in childhood in particular has its own characteristics. Despite the existence of different views on the treatment of TMJ ankylosis, various techniques have been defined, and three basic techniques are currently employed: gap arthroplasty, interpositional arthroplasty and joint reconstruction. Our study is intended as a statistical inquiry into the contribution to the operation success of the three different methods of treatment. Moreover, the effect on treatment outcome of unilateral or bilateral ankylosis is also statistically evaluated. In our study, eight cases were treated with gap arthroplasty, nine with interpositional arthroplasty and seven with joint reconstruction performed by costochondral graft. As a result of our statistical evaluation, it was determined that the effect of interpositional arthroplasty on post-operative maximal interincisal mouth opening was greater than that observed with the other methods.Öğe Determinants of MR relaxation rates in jaw cysts: implications for diagnostic values of the relaxation times(British Inst Radiology, 2004) Erol, B; Yilmaz, U; Tanrikulu, R; Yilmaz, AObjectives: The MRI signal intensities and the relaxation times (T-1 and T-2) have already been used for comparisons among various types of cysts. The signal intensities (or T-1 and T-2) were suggested to be related to cyst content. However, such a relationship between the relaxation rates (1/T-1 and 1/T-2) and the aspirated content of jaw cysts was not given. Therefore, an investigation on the determinants of the relaxation rates in the jaw cysts may be helpful in elucidating the biological basis for the differences in relaxation rates among the categories of jaw cysts. Methods: The aspirated contents of 23 cysts (16 radicular and 7 haemorrhagic) were scanned using an MR imager operating at 1 T magnetic field strength. The viscosities and the dry-weight-to-water-weight ratios (Ms/Mw) were determined. Also, the mean values of cyst categories were compared using statistical analysis. Results: The 1/T-1 had a moderate correlation with viscosity (0.66) and Ms/Mw (0.56), while the 1/T-2 had a good correlation with viscosity (0.87) and Ms/Mw (0.82). The mean values of viscosity, Ms/Mw and relaxation rates in radicular cysts were significantly lower (P < 0.05) than those of haemorrhagic cysts. Conclusions: The present data suggest that similarities and differences between relaxation rates of radicular and haemorrhagic cysts can be explained by the solid content and viscosity of cysts.Öğe A histopathological evaluation of tissue reaction to stainless steel and titanium miniplate systems in bone(Medimond S R L, 1997) Unlu, G; Gulsun, B; Erol, B; Yaldiz, MTissue reaction to loaded stainless steel and titanium screws in bone was evaluated. These materials were implanted in each tibia of 12 rats. The animals were sacrificed at the 1(st), 3(rd) and 12(th) weeks and histopathological examination was performed. From the histological evidence obtained in this study there was no discernible difference in bone healing around stainless steel and titanium screws atl, 3 and 12 weeks after insertion.Öğe A massive pleomorphic adenoma of the submandibular salivary gland(W B Saunders Co, 1997) Erol, B; Ozer, N; Unlu, G; Gulsun, B[Abstract Not Available]Öğe Restoration technique of Wharton's duct after excision of a large sialolith associated with a chronic supurative sialadenitis case(Medimond S R L, 1997) Erol, B; Ozer, N; Gulsun, B; Tanrikulu, RSialolithiasis (stones) is the occurrence of calcareous concretions in the salivary ducts or glands. It is thought that, the common involvement of the submandibular gland occurs in its duct. Salivary stones may cause chronic sialadenitis. If the etiologic factor is eliminated, there is generally subsidence of the clinical manifestations of the disease. In our study, removal of a large sialolith from the right submandibular duct and restoration technique of Wharton's duct that was applied to a 64-year-old man who referred to our clinic because of growth under the tongue and painless swelling in right submandibular gland presented.
