Cholestetoma

OBJECTIVE: Multiple alternative approaches of cochlear implant surgery have been described, such as the suprameatal approach, transcanal approach, transmeatal approach and middle cranial fossa approach. Transmeatal (open trnascanal) approach has not been adapted since first described in the clinical field. we aimed to assess the long-term complications of the transmeatal approach in a series of 131 patients at our center between 2004 and 2008. METHODS: This study was a retrospective case series of all patients who underwent cochlear implants with the transmeatal (open transcanal) approach from May 2004 to December 2008 at King Faisal Specialist and Research Hospital (Riyadh, Saudi Arabia), which were conducted by the same surgeon...

Temporalis fascia has long been regarded as the ideal graft material for tympanic membrane repair. However it often does not seem to withstand negative middle ear pressure in the post operative period. Tragal cartilage with perichondrium would appear to be a better graft material with good hearing outcome. It can be obtained easily with cosmetically acceptable incision. In the present study, we have compared the graft properties of temporalis fascia verses tragal cartilage perichondrium with respect to healing, hearing and rate of post operative retraction or reperforation...

INTRODUCTION: Certain problems in ear surgery are caused by temporal bone cholestetoma and chronic otitis media complicated by deafness, facial nerve dysfunction, vertigo or meningcephalocele. Lateral petrosectomy offers possibility of radical treatment and prevention of temporal bone destruction and following complications. AIM OF STUDY: It is an analysis of indications for lateral petrosectomy and it's results as a treatment of otitis media and temporal bone cholesteatoma...

A patient with a large congenital cholesteatoma of the left temporal bone is presented. The case is unique in that, although the cholestetoma invaded all three semicircular as well as the basal coil of the cochlea, the patient retained normal hearing. She had an almost complete left-sided facial paralysis, yet she retained sensori-neural hearing postoperatively, in spite of removal of the superior part of the labyrinth (semicircular canals and utricle). The possible mechanisms behind such an unusual event are discussed together with the possible function of the utriculo-endolymphatic valve...
