Occurence of a round window membrane rupture in patients with sudden sensorineural hearing loss
UNLABELLED BACKGROUND Aim of the present study was to evaluate the occurence of a round window membrane rupture and the effects of hearing restoration after exploratory tympanotomy and sealing of the round window (niche) in patients with unilateral sudden deafness. METHODS Retrospective analysis of patients' charts in a tertiary referral center. Charts of 69 patients with sudden deafness f...
متن کاملRound window membrane motion before and after stapedotomy surgery - an experimental study.
This paper presents the results of non-contact measurements of the human ear round window (RW) membrane motion in freshly harvested human cadaver temporal bone specimens. A PSV 400 Scanning Laser Vibrometer system (Polytec, Waldbronn, Germany) was used to determine the effect of stapedotomy on the sound-induced displacement amplitude of the RW membrane. The vibration patterns were measured in t...

This study evaluated the histopathologic changes in the round window niche. , and membrane in cases of chronic suppurative otitis media. The pathologic process was found in all subjects. Fibrocystic or fibrous tissue was most commonly seen, while active granulation was less developed. The round window membrane was thicker and inflamed throughout its layers. Inflammatory invasion of the inne...
متن کاملMesothelial cell proliferation in the scala tympani: a reaction to the rupture of the round window membrane.
The inner layer of the round window membrane is composed of mesothelial cells and this mesothelial cell layer extends to the scala tympani. This study describes the histopathologic findings of temporal bone analysis from a patient with bilateral perilymphatic fistula of the round window membrane. The left ear showed proliferation of mesothelial cells in the scala tympani of the basal turn adjoi...
