BACKGROUND Some patients with chronic middle ear disease and multiple failed revisions, who also need a hearing aid, may benefit from an active middle ear implant. An advantage of an active middle ear implant is that the ear canal is unoccluded. METHODS Following extensive experimental development in temporal bones and investigations of various locations and attachments of a Vibrant Soundbrid...

BACKGROUND AND PURPOSE Prior descriptions of imaging after failed stapes procedures for otosclerosis predated currently available CT technology and/or failed to assess commonly used metallic implants. The purpose of this study was to correlate temporal bone CT findings with clinically and intraoperatively determined causes of surgical failure. MATERIALS AND METHODS All patients with otosclero...

OBJECTIVE To perform a systematic review of observational studies reporting hearing outcome in primary stapes surgery where a heat-crimping prosthesis was used. DATA SOURCES Medline, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, TRIP database, Clinical Trials Registry, ISI Web of Knowledge, and Web of Science. The search was performed on January 1, 2...

The article gives an overview of the historical development of stapedectomy beginning with Kessel in 1876. Then, from the beginning to the middle of the 20th century, surgery on the oval window became obsolete, opening the way for an era of fenestration operations until Shea in 1956 performed the first modern stapedectomy using a Teflon stapes replacement prosthesis. Since then, numerous surgeo...

OBJECTIVE The aim of this study was to evaluate changes in bone conduction thresholds before, during and after total stapedectomy. STUDY DESIGN Prospective clinical study. METHODS In 27 ears of 26 patients undergoing stapedectomy under local anesthesia, bone conduction was measured before surgery, during surgery under open oval window conditions, and after the insertion of a steel wire conn...

BACKGROUND Otosclerosis is characterized by bony deposits in the otic capsule, resulting in stapes fixation and progressive hearing loss. It can be treated effectively by surgically removing (part of) the stapes and replacing it with a prosthesis. Increasingly, stapes surgery is performed as a day-case procedure. The major drive towards day-case surgery has been out of economic considerations. ...

Objective. To visually compare the Nitinol "smart" stapes prosthesis to conventional manual crimping stapes pistons in temporal bone cadaver specimens. Main Outcome Measures. 10 otolaryngologists were given a photograph of the randomly ordered stapes pistons and asked to use the pictures to answer questions about each stapes piston. The answers to the survey were then recorded for analysis. Res...

Introduction:Different types of prosthesis are available for stapes replacement. Because there has been no published report on the efficacy of the titanium soft-clip vs the fluoroplastic Causse loop Teflon piston, we compared short-term hearing results of both types of prosthesis in patients who underwent stapedotomy due to otosclerosis.Materials and Methods:A total of 57 ears were included in ...

Numerous attempts to deal surgically with otosclerosis were made before the current method of stapedectomy with stapes prosthesis was established. We report a case with unique CT findings of a patient who underwent fenestration surgery for otosclerosis in the early 1940s. Recognition of this old surgical procedure on the imaging scans may avoid misdiagnosis of labyrinthine fistulae or middle an...
