Piston stapes prostheses are implanted in patients with refractory conductive or mixed hearing loss due to stapes otosclerosis to stimulate the perilymph with varying degrees of success. The overclosure effect described by the majority of researchers affects mainly low and medium frequencies, and a large number of patients report a lack of satisfactory results for frequencies above 2 kHz. The m...

Aim of the study was to investigate, in a randomized prospective trial, air-conducted vestibular evoked myogenic potentials (AC-VEMPs) and bone-conducted vestibular evoked myogenic potentials (BC-VEMPs) before and after successful stapedotomy. Enrolled in the study were 41 consecutive patients (32 female, 9 male; mean age 36 years) (42 ears) with otosclerosis. Audiological evaluations and diagn...

INTRODUCTION The major objective of a stapedotomy is the restoration of hearing. In training centers, the hearing results obtained by resident physicians are lower than those achieved by more experienced surgeons. An analysis of the surgical results obtained by resident physicians is essential to identification of the deficiencies in the learning process. OBJECTIVE To analyze the postoperativ...

UNLABELLED In otosclerosis patients the most common procedure followed at Otosurgical Dept. Medical University of Lodz is stapedotomy with insertion of teflon-piston prosthesis. When surgery is finished a whisper hearing test is done from the 1 meter distance for brief intraoperative hearing improvement assessment. There is a number of patient who report subjective intraoperative hearing improv...

OBJECTIVE To study the success results rates and complications of stapedotomy compared to stapedectomy in the operative management of otosclerosis. METHODS This is a retrospective study of 50 patients who were treated surgically for otosclerosis. The medical records of these patients were reviewed for the type of operation performed, complications and the serial pure tune audiometries pre- an...

Since the advent of stapedotomy and its use in the treatment of otosclerosis, a few complications have been reported in the literature. Among them, the granulomatous reaction, described by Harris and Weiss in 1962, is rare. It is an excessive inflammation that forms granulation tissue around the prosthesis and the oval windows. Although the etiology is uncertain, several authors believe that th...

Statement of Problem. Stapedotomy is the treatment of choice for otosclerosis. Numerous techniques and prosthesis are available to perform this procedure. Success rates of surgery vary from 17% to 80%, and revision surgery carries an increased risk of complications as well as poorer hearing outcomes. Method of Study. Case report. Results. We report the first case of uncrimping of a SMart stapes...

OBJECTIVES/HYPOTHESIS To evaluate the long-term (5-year) results of the shape-memory nitinol stapes piston in the surgical treatment of otosclerosis. STUDY DESIGN Retrospective case review in a tertiary referral center. METHODS The patients were adults with clinically proven otosclerosis undergoing stapedotomy. Stapedotomy and ossicular chain reconstruction using a shape-memory nitinol stap...

Abstract Background Stapedotomy is being performed endoscopically for otosclerosis in Sudan since 2011 with increasing number of patients. This prospective hospital-based study from Nov 2016 to 2020 states the clinic-demographic features otosclerosis; it describes this surgical technique and hearing outcome following endoscopic stapedotomy. Results Total included was 91 Females were 48, males 4...
