Studies on Amphibian Metamorphosis Xvii. Influence of Non-living Annular Tympanic Cartilage on Tympanic Membrane Formation
INTRODUCTION THE tympanic membrane of the adult frog is divisible into three histologically distinct parts, viz. an inner epithelial layer, continuous with the mucous membrane of the tympanic cavity, the former being closely applied to a thin lamina propria conforming in shape and area to that of the annular tympanic cartilage to which it is attached at its peripheral borders. The third and out...
متن کاملFirst branchial cleft; Congenital anomalies; Facial nerve; Tympanic membrane duplication, Tympanic membrane triplication
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 کاملEffects 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 کاملTympanosclerosis in the tympanic membrane: influence on outcome of myringoplasty.
The effect of the presence of tympanosclerotic plaques in tympanic membrane on the outcome of a myringoplasty procedure was evaluated in this retrospective study. Long-term results of 714 myringoplasties were analyzed, and of these, 555 were eligible for further study. Three groups were studied separately: ears without tympanosclerosis, ears with a plaque not exceeding one third of the tympanic...
