Effects of tympanic membrane abnormalities on auditory function.
This article discusses how several diagnostic tools used by audiologists inter-relate to anatomical abnormalities viewed by video otoscopy. Background of common middle ear pathology is reviewed, with emphasis on new research findings regarding pathophysiology. A review of video otoscopy, multifrequency tympanometry, and otoreflectance is provided. Case studies illustrate the integrated use of t...
متن کاملTympanic membrane oscillations and auditory receptor activity in the stridulating cricket Gryllus bimaculatus.
The ears of stridulating crickets are exposed to loud self-generated sounds that might desensitise the auditory system and reduce its responsiveness to environmental sounds. We examined whether crickets prevent self-induced auditory desensitisation, and measured the responsiveness of the peripheral auditory system of the cricket (acoustic spiracle, tympanic membrane and tympanic nerve) during p...

Methods: We conducted a retrospective chart review of all patients consecutively referred to the senior authors at a tertiary-care Pediatric Otolaryngology clinic for fi rst branchial cleft anomalies over a 14-year period. Patients underwent computerized tomography scan with contrast, otoscopy plus tympanic microsurgery, when indicated (29%), methylene blue mapping of the cutaneous opening, whe...
متن کاملTympanic membrane organ culture using cell culture well inserts engrafted with tympanic membrane tissue explants.
Tissue engineering approaches using growth factors and various materials for repairing chronic perforations of the tympanic membrane are being developed, but there are surprisingly few relevant tissue culture models available to test new treatments. Here, we present a simple three-dimensional model system based on micro-dissecting the rat tympanic membrane umbo and grafting it into the membrane...
متن کاملCholesteatoma of external auditory canal: a case report.
The authors present a case of cholesteatoma of external auditory canal (CEAC) with extensive invasion of mastoid; ossicle chain and tympanic membrane remained intact. The only symptom was chronic otorrhea. Diagnosis was based on clinical elements and CT scan was used to measure pathology and program surgery. Treatment was modified radical mastoidectomy associated with meatoplasty. Due to the in...
