OBJECTIVES/HYPOTHESIS To review surgical findings and hearing outcomes of incus footplate assembly (IFA) for the patients with conductive hearing loss due to missing stapes superstructure with a mobile stapes footplate. STUDY DESIGN Retrospective case review and survey. METHODS Pre- and postoperative audiometric data and intraoperative findings were reviewed. Postoperative air-bone gap (ABG...

BACKGROUND Recently, a model of the ossicular chain for finite element analysis has been developed. However, the natural vibration characteristics of human ossicles have never been studied. Herein, we investigated the dynamic characteristics of the coupling of in-vivo ossicles using finite element analysis. METHODS The geometry of the ossicular chain was obtained by high-resolution computed t...

INTRODUCTION The use of ossicular graft material in ossicular chain reconstruction has significantly improved hearing results hearing after tympanoplasty and tympanomastoid surgery for chronic otitis media. Today, otologists have a wide array of tools from which to choose, but may find it difficult to know which middle ear implant works best. MATERIALS AND METHODS A prospective study of 80 pa...

The objective of our study was to determine the effect of continuous jejunal interposition on gastrointestinal hormones after distal gastrectomy, and lay a foundation for surgical management.Distal subtotal gastrectomy experimental model were established on 24 adult Beagle dogs. Digestive tract reconstruction of the dogs was randomly divided into continuous jejunal interposition group, Billroth...

Anomaly of the ossicles is frequently seen in a patient with congenital anomalies of the head or face, such as congenital obstruction of the external ear canal, Treacher Collins syndrome or cephalopathy. Congenital anomaly of the ossicles however is not a rare occurrence even in a patient without anomalies of the head or face. Here, we would present our own experience with six cases of congenit...

OBJECTIVE To analyze the results obtained from hydroxyapatite bone cement repair of ossicular discontinuity between the incus and stapes during surgery of retraction pockets. DESIGN Clinical study of a case series. SETTING Otolaryngology Department, Tanta University Hospitals, Tanta, Egypt. PATIENTS A total of 62 previously untreated patients (82 ears) with retraction pockets. INTERVENT...
