The fistula of the round window of the cochlea
Vestnik otorinolaringologii, 2017This article presents the data on the frequency, diagnostics, and variants of the surgical treatment of the fistula of the round window of the cochlea. A case of this pathology is reported with the special emphasis placed on the approaches to the diagnostics and surgical management of this condition.

Stapedectomy and round window closure
The Laryngoscope, 1987AbstractRound window closure is an uncommon complication of advanced otosclerosis found in 1% of 30,000 stapedectomy cases. A review of 81 patients representing 110 operation cases was made to determine what factors may alert the otologic surgeon to the patient with round window closure and what factors may identify the patient who will achieve the ...

Modelling the effect of round window stiffness on residual hearing after cochlear implantation
Hearing Research, 2016 Preservation of residual hearing after cochlear implantation is now considered an important goal of surgery. However, studies indicate an average post-operative hearing loss of around 20 dB at low frequencies.

A method is described in the report of Wever and Bray 1 that is accurate and reliable and makes it possible for the first time to study the effect of experimental lesions of the sound transmitting apparatus in animals. Cats were used by us because of the simplicity of the required cerebellar approach and the ease with which the middle ear may be ...

ProblemRound window is the main target in many modern otologic procedures. Unfortunately it is approached either blindly or indirectly in most of these procedures. Others necessitate a complex technique in order to be directly approached. Many failures have been shown to be due to difficulties in the approach and/or anatomical variations.

Submicroscopic Studies of the Round Window Membrane
Acta Oto-Laryngologica, 1971A study of the ultrastructure of the round window membrane revealed several interesting characteristics of functional significance. The membrane consists of three layers: (1) An external layer faces the tympanic cavity and varies from one to two cells in thickness.

The Round Window in Acute Hearing Loss
International Journal of Audiology, 1982Sensorineural hearing loss has various etiologies. One of them is perilymphatic fistula, which is observed in (1) congenital malformation of the internal ear in children: (2) after operations on the oval window (stapedectomy, interposition); (3) in cases of head trauma, and (4) in acute hearing loss of unknown origin.

The Ultrastructure of the Round Window Membrane of the Cat
ORL, 2010The ultrastructure of the round window membrane of the cat was investigated. Three distinct layers were recognised and described. It was established that the outer epithelial layer is non-ciliated, but often contains microvilli. The middle layer, under the basement membrane, contains a large amount of collagen and elastic fibres in addition to ...

A review of the radiological anatomy of the round window
The British Journal of Radiology, 1979Experimental studies on dried temporal bones in various projections combined with studies of the anatomical details marked with metal wires and/or barium paste have been performed to define the round window and its anatomical relation to surrounding structures. The exact plane of the round window was not found to be tomographically demonstrable and the

In the context of cochlear implantation, visualization of the round window is very important: first, if the electrode is inserted directly through the round window membrane, and second when a cochleostomy is performed, the round window serves as an important landmark.
