PATIENTS AND METHODS: Clinical and surgical records of 91 patients (29 men, 62 women; mean age 48 years; range 18 to 82 years) with otosclerosis were reviewed following stapedotomy with the small fenestra technique without interposition. The same Teflon-platinum piston was used in all the patients. Audiometric tests were performed within a week before the operation, 5 to 7 days (early evaluatio...

OBJECTIVE We evaluated functional results after stapedotomy in terms of the influence of preoperative hearing threshold. STUDY DESIGN Case series and chart review. SUBJECTS AND METHODS We classified 141 patients according to preoperative mean air-conduction threshold: 40 to 54 dB, group 1; 55 to 69 dB, group 2; and 70 to 89 dB, group 3. Speech discrimination scores also were noted. RESULT...

Background Although the utility of laser fiber in microscopic stapes surgery has been documented past, their role can be highly emphasized endoscopic surgery, especially difficult anatomical situations. Methods This is a retrospective analysis cases where total 46 patients (22 conventional stapedotomy and 24 CO2 laser-assisted stapedotomy) were included study. The clinical parameters assessed b...

The aim of this study was to investigate the possibility that an abnormality related to parathyroid hormone (PTH) action is involved in the increased bone turnover observed in otosclerosis. To do so, expression and function of the PTH-PTH-related peptide (PTHrP) receptor were studied in the involved tissue (stapes) and compared with that in control bone sample obtained from the external auditor...

INTRODUCTION Cholesteatoma is traditionally diagnosed by otoscopic examination and treated by surgery. The necessity for imaging in an uncomplicated case is controversial. This study was planned to investigate the usefulness of a preoperative high-resolution computed tomography (HRCT) scan in depicting the status of middle ear structures in the presence of cholesteatoma and also to compare the ...
