HYPOTHESIS Ossiculoplasty using prosthetic reconstruction with a malleus assembly to the stapes head will result in better transmission of vibrations from the eardrum to the stapes footplate than reconstruction with a tympanic membrane assembly to the stapes head. Both types of reconstruction will be affected by tension of the prosthesis. BACKGROUND Theories (and some clinical studies) that t...

Keypoints * The successful use of glass-ionomeric cement in primary stapes surgery for attachment of the wire loop of the stapes prosthesis to the long process of the incus is reported. * Early hearing outcomes were similar in patients where cement was used for stapes prosthesis attachment compared with those with standard wire crimping technique. * Use of glass-ionomeric cement to attach the s...

background & objectives: the aim of this study was to compare the effectiveness of two stapes prostheses in hearing improvement of patients undergoing stapes surgery for otosclerosis.   materials & methods: in this retrospective and descriptive study, the charts of 291 stapedectomies performed by one surgeon (first author) from 1997 to 2011 in imam khomeini and apadana hospitals of ahva...

Introduction Otosclerosis is a disease that causes bone resorption and deposition in the auditory structures, leading to deafness. Many studies have evaluated the histopathology of the stapes footplate in this disease (osteoblasts, osteoclasts, vascular proliferation, fibroblasts, and histiocytes), but we found no studies in the literature involving the histology of the superstructure of the st...

PURPOSE CT analysis of the stapes is difficult in the axial plane (AP), because of its oblique orientation. Oblique axial reformations could provide a more precise analysis of the stapes in normal and pathologic conditions. MATERIALS AND METHODS CT of the temporal bone was performed in 31 patients. Only the normal side was examined in the AP and oblique axial plane (OAP), in the plane of the ...

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...

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. ...

Introduction Observing the obliquity of stapes by closely scrutinizing the HRCT temporal bone in otosclerosis revealed a reliable and consistent finding. This finding can add to the existing radiological criteria in diagnosis of otosclerosis. Objective The objective of this study is to establish the obliquity of stapes in otosclerosis by radiological measurements using HRCT temporal bone by com...

OBJECTIVES A non-progressive and conductive hearing loss with normal eardrum, but no history of trauma and infection, is highly suggestive of a congenital ossicular malformation. Among ossicular anomalies, stapes anomaly is the most common. The purpose of this study is to describe patterns of stapes anomaly and to analyze its surgical outcome with special reference to its patterns. METHODS We...

PURPOSE Otosclerosis is a metabolic bone disease of the otic capsule that can cause the stapes fixation, resulting in conductive hearing loss or, in a profound sensorineural deafness threshold. Surgery is one of the possible treatments for the otosclerosis. To repair small focus of otosclerosis in the anterior crus of the stapes, in 1960, Hough suggested the implementation of a technique in whi...
