Round Window Vibroplasty in Infants and Children with Atretic Ear

Otolaryngology–Head and Neck Surgery, 2013
Objectives:Evaluate long‐term safety and outcome of round window vibroplasty (RWVPL) by the placement of the floating mass transducer (FMT) on the round window membrane in infants and children with congenital aural atresia (CAA).Methods:External auditory canal and middle ear malformation, accompanied by more or less severe conductive or mixed hearing ...

Passage through the round window membrane and inner ear function

Audiological Medicine, 2004
The round window membrane (RWM) is an anatomical barrier between the aerated middle ear and the fluid (perilymph) compartments of the cochlea. Permeability of the RWM is regarded as an accident and not as a function of the membrane because of its anatomical characteristics, location and the high prevalence of middle ear disease.

The ear of the chameleon: The round window problem.

Journal of Experimental Zoology, 1969
AbstractAn examination of serial sections of the ears of several specimens of Chamaeleo senegalensis and Chamaeleo quilensis gives support to an earlier suggestion that these ears function by means of a substitute round window. The usual type of round window is absent, but there is a tortuous pathway leading from the scala tympani through the ...

Enhanced oval window and blocked round window passages for middle–inner ear transportation of gadolinium in guinea pigs with a perforated round window membrane

European Archives of Oto-Rhino-Laryngology, 2013
To elucidate the communication between the middle and inner ear, and the fluid dynamics of the inner ear with the perilymphatic fistula (PLF) of the round window membrane (RWM). The PLF of the RWM was created in nine guinea pigs. Gadolinium diethylenetriamine pentaacetic acid bismethylamide (Gd-DTPA-BMA) was delivered into the middle ear and followed ...

Round window application of an active middle ear implant (AMEI) system in congenital oval window atresia

Acta Oto-Laryngologica, 2015
Application of the Vibrant Soundbridge to the round window (RW) membrane can be utilized as an efficient therapy for congenital oval window (OW) atresia.To report the surgical technique and auditory outcome of an active middle ear implant (AMEI) system used in patients with congenital OW atresia.Nine subjects with congenital OW atresia (six males and ...

Inner ear inflammation and round window otosclerosis.

The American journal of otology, 1993
Recently, it has been suggested that otosclerosis represents the host's ongoing immunologic response to measles or other viral antigens. Documentation of past inflammation within the inner ear would serve as further evidence that this mechanism may be at play in the pathogenesis of the disease.

Ciprofloxacin and the Inner Ear - A Morphological and Round Window Membrane Permeability Study

ORL, 1992
This study was conducted in order to evaluate ototoxic potential and passage through the round window membrane of ciprofloxacin, a newly developed antimicrobial drug with an antibacterial spectrum well suited for the treatment of suppurative otitis media.

Ultrastructural Organization of the Round Window Membrane in the Infant Human Middle Ear

ORL, 1983
Ultrastructural studies of the round window membrane in infants revealed that the membrane is made up of three layers. The relatively wide outer epithelial layer consists of 3-4 cell layers and is formed by cuboidal and round cells. The outer two or three cell layers contain mainly rough endoplasmic reticulum and secretory granules, indicative of a ...
