Anterior atticoantrostomy for cholesteatoma surgery.

OBJECTIVES: We aimed to investigate the long-term results of anterior atticoantrostomy in adult patients with cholesteatoma. METHODS: A total of 83 ears in 78 patients were operated on by the anterior atticoantrostomy technique, supported by a periosteal flap, between 1991 and 2002. RESULTS: Cholesteatoma recurred in only 4 ears (4.8%). In the 79 ears without recurrence, re-perforation was observed in 3 ears (3.8%), and retraction pockets developed in the attic of 5 ears (6.3%), 2 of which needed ventilation tubes. Absorption or migration of cartilage grafts was not seen in any of the patients. The mean air-bone gap was 34.8 +/- 13.4 dB and 16.9 +/- 14.7 dB, and the mean high-tone bone conduction was 19.0 +/- 6.2 dB and 21.1 +/- 6.6 dB, in the preoperative and postoperative periods, respectively. CONCLUSIONS: In the reconstruction of the posterior canal wall, a cartilage graft supported by a periosteal flap prevents attic retraction and may increase the vascularization of the graft. After anterior atticoantrostomy, the recurrence rate and the probability of leaving residual tissue are low. Therefore, we believe that anterior atticoantrostomy is a relatively safe and effective technique that can be used in the management of cholesteatoma.

[Treatment options and common problems in patients with maxillofacial trauma].

BACKGROUND: The approach and type of management along with the common complications in maxillofacial trauma were evaluated in this study. METHODS: Medical records of 602 patients (486 males; 116 females; mean age 28,4+/-15,2; range 1 to 80 years) with maxillofacial fractures, admitted to the Department of Otolaryngology between 1992 and 2004, were evaluated in this study. Maxillofacial fracture was diagnosed by clinical and radiological findings. Sex and age distribution of patients, etiology of trauma, localization of the fractures, treatment modalities, time to treatment after the trauma and postoperative complications were recorded. RESULTS: There were 257 (42,7%) mandible, 156 (25,9%) nose, 66 (11%) maxillary, 34 (5,6%) zygoma, 32 (5,3%) multiple facial, 29 (4,8%) blow-out and 28 (4,7%) frontal sinus fractures. While 256 (43%) patients underwent closed reduction, 346 (57%) patients were treated by open reduction. Postoperative complications were seen in 8,3% (51) of patients. CONCLUSION: Although associated with some complications, open reduction and miniplate fixation should be the preferred treatment option, since it provides a powerful fixation, is easy to perform, and has better esthetic and cosmetic results.

[Petrous bone lesions].

OBJECTIVES: We evaluated the results of treatment and follow-up of patients with petrous bone lesions. PATIENTS AND METHODS: We retrospectively evaluated 13 patients (5 females, 8 males; mean age 33.8+/-17.4 years; range 4.5 to 65 years) who were treated and followed-up for petrous bone lesions between 1990 and 2004. The diagnoses were cholesterol granuloma (n=2; 15.4%), chondrosarcoma (n=1; 7.7%), and cholesteatoma (n=10; 76.9%). RESULTS: Patients with cholesterol granuloma had complaints of cephalgia and diplopia while those with cholesteatoma complained of otorrhea and hearing loss. One patient with cholesterol granuloma and eight patients with cholesteatoma underwent surgical operations with the use of middle skull base approach (n=1), transcochlear approach (n=2), translabyrinthine approach (n=1), and tympanopetrosectomy (n=5). Two cases with congenital cholesteatoma and one patient with cholesterol granuloma refused surgical intervention and were only followed-up. CONCLUSION: Besides surgical intervention, follow-up by computed tomography or magnetic resonance imaging may be considered in patients with incidental petrous bone lesions, presenting with limited symptoms.
