Severe to profound mixed hearing loss is associated with hearing rehabilitation difficulties. Recently, promising results for speech understanding were obtained with a direct acoustic cochlear implant (DACI). The surgical implantation of a DACI with standard coupling through a stapedotomy can however be regarded as challenging. Therefore, in this experimental study, the feasibility of direct ac...

Introduction: Otosclerosis one of the most common causes of conductive hearing loss is more common in females and in their middle ages. It is usually a bilateral and progressive disease. Surgical operation is suggested as the exclusive management of otosclerosis. This study aims to evaluate the hearing results after stapedectomy in otosclerotic patients in Ahwaz. Materials and Methods:  In t...

OBJECTIVE Use of the SMart piston, a nitinol-based, self-crimping prosthesis in stapes surgery may allow improved functional results because of better sound transmission properties at the incus-prosthesis interface because of the elimination of manual crimping. Possible disadvantages include thermal damage or strangulation of the incus and its mucoperiosteum or nickel intolerance. The goal of t...

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...

OBJECTIVES To study children who had undergone stapedectomy at an age younger than 16 years to determine the causes (particularly frequency of congenital anomalies vs otosclerosis) and to analyze the functional results over the short-term, 1-year, and long-term postsurgery time course. DESIGN Ten-year retrospective study covering 1998 to 2008. SETTING Pediatric tertiary care centers. PATI...

OBJECTIVE To assess the reliability of high-resolution computed tomographic scan (HRCT scan) for the diagnosis of otosclerosis and to determine its usefulness to predict hearing deterioration and surgical difficulties. STUDY DESIGN Prospective study. SETTING Tertiary reference center. PATIENTS Two hundred nine ears (200 patients) presenting progressive conductive hearing loss with normal ...

The aim of this work has been to evaluate the use of Piezosurgery in the different otological surgical techniques. Piezoelectric bone surgery, also known simply as Piezosurgery, is a new technique for osteotomy and osteoplasty. The equipment consists of two piezoelectric handpieces and two inserts that are connected to a main unit. This unit supplies power and has holders for the handpiece and ...
