laseror microdrill-assisted technique may enable better outcomes in terms of intraand post-operative complications as well as of hearing gain as compared with classical stapedotomy technique. Materials and Methods: Eighty-two subjects undergoing primary stapes surgery for otosclerosis were enrolled for this study as having a least pure tone average (PTA) air-bone gap (ABG) of 35 dB. Patients we...

Otosclerosis is the most frequent cause of conductive hearing loss in patients with intact tympanic membrane. It can be treated by surgery with various techniques. Because of limited manipulation and comparably similar results, stapedotomy at present is preferred over other surgical techniques by most surgeons. Here we present the operative results of 114 otosclerotic patients who underwent sta...

OBJECTIVE To evaluate hearing results and postoperative dizziness after stapedotomy with application of sodium hyaluronate gel (HG) to the oval window niche during fenestration of the footplate. STUDY DESIGN Case-control study comparing 27 stapedotomies with HG and 32 stapedotomies without HG. OUTCOME MEASURE Preoperative and postoperative audiometric data, postoperative dizziness (vertigo ...

Surgery for otosclerosis is simple in concept, yet good outcomes rely on successful execution of the fine details and the avoidance of complications. There are many descriptions of operative procedures for otosclerosis in the literature, including those by this author. These generally describe the basic elements of the operation in a sequential manner but do not focus on the particular critical...

BACKGROUND Otoacoustic emissions (OAEs) are influenced in otosclerosis. The aim of the current study was to investigate the profile of transient evoked (TEOAEs) and distortion product otoacoustic emissions (DPOAEs) in association with multifrequency tympanometry measures in otosclerotic patients undergoing 2 types of stapes surgery: small fenestra and microtraumatic stapedotomy. MATERIAL AND ...

Piston-stapedotomy is the most common method for hearing restoration in patients with otosclerosis. In this study, we have experimentally examined a prototype of a new chamber stapes prosthesis. The prototype was implanted in a human cadaver temporal bone. The round window vibrations before and after implantation were measured for the acoustic signal (90 dB SPL, 0.8-8 kHz) in the external audit...

OBJECTIVE To compare the hearing and otoacoustic emissions (OAE) outcome of stapedotomy employing 0.4 and 0.6 mm diameter prostheses. MATERIALS AND METHODS In total, 18 patients with otosclerosis participated in a prospective, double-armed, randomized cohort study. All the patients underwent small fenestra drill stapedotomy employing the Causse fluroplastic large loop piston prostheses. The p...

stapedotomy. Materials and Methods: The diameters of prostheses used were 0.3 mm and 0.6 mm in two groups of ten patients. and 10 healthy patients as control group were included. Transient evoked otoacoustic emissions (TEOAE), Distortion product otoacoustic emissions (DPOAE) and DPOAE I/O functions were recorded. Results: Significant changes were detected at 2000-3000 Hz (p<0.001) and 4000-6000...

UNLABELLED Otosclerosis causes the fixation of the stapes and conductive hearing loss, usually corrected with the use of hearing aids or through stapedotomy and the replacement of the involved stapes with a prosthesis. Titanium has been the most recently used material of choice in stapedotomy prostheses. Only two prostheses are commercially available in Brazil. There are no reports in the liter...
