BACKGROUND Cochlear implantation has become a mainstream treatment option for patients with severe to profound sensorineural hearing loss. During cochlear implant, there are key surgical steps which are influenced by anatomical variations between each patient. The aim of this study is to determine if there are potential predictors of difficulties that may be encountered during the cortical mast...

OBJECTIVES/HYPOTHESIS Objectives were to describe the use of round window plugging for superior semicircular canal dehiscence syndrome and review further recommendations regarding the procedure based on our experience and to compare results with recent literature on round window plugging. STUDY DESIGN Retrospective case series. METHODS Fourteen patients underwent round window plugging for s...

Objective To evaluate incidence of interscalar excursions between round window (RW) and cochleostomy approaches for cochlear implant (CI) insertion. Methods This was a retrospective case-comparison. Flat-panel CT (FPCT) scans for 8 CI users with Med-El standard length electrode arrays were collected. Surgical technique was identified by a combination of operative notes and FPCT imaging. Four ...

Objective: To study the variations in the course of the facial nerve by studying the second genu angle (S.G.A.) aiming to provide a more detailed description of the anatomy of the nerve, thus avoiding its injury during middle ear surgery. Material and Methods: 35 adult temporal bones were studied by dissecting them at the temporal bone laboratory in Ain Shams University Specialized Hospital (AS...

OBJECTIVES Rupture of the round window membrane with consecutive development of a perilymphatic fistula (PLF) is still a matter of controversial debate in the pathogenesis of idiopathic sudden sensorineural hearing loss (SSHL). Until now no consensus exists about whether these patients benefit from performing an exploratory tympanotomy with sealing of the round window. The aim of the present st...

Introduction: The round window membrane (RWM) acts as a pressure-relieving for incompressible cochlear fluid. reinforcement of the RWM has been used surgical intervention treatment superior semicircular canal dehiscence and hyperacusis. aim this study was to investigate how affects sound pressure variations in cochlea. Methods: intracochlear (ICSP) simultaneously measured scala tympani (ST) ves...
