Jan 1, 2025 · A perilymphatic fistula (also known as a perilymph fistula or labyrinthine fistula) is a pathologic communication between the fluid-filled space of the inner ear and the air-filled space of the middle ear, most commonly occurring at either the round or oval window.

A labyrinthine fistula is an abnormal opening in the inner ear. This can result in leakage of the perilymph into the middle ear. [1] This includes specifically a perilymph fistula (PLF), an abnormal connection between the fluid of the inner ear and the air-filled middle ear.

Jul 19, 2023 · Labyrinthine fistula is an abnormal communication between the inner ear and the surrounding structures. Labyrinthine fistulas are formed most commonly between the inner ear (round window or oval window) at the fissula ante fenestrum and surrounding structures, causing perilymph leakage.

A perilymphatic fistula (PLF) is an abnormal communication between the perilymph-filled inner ear and outside the inner ear that can allow perilymph to leak from the cochlea or vestibule, most commonly through the round or oval window.

Jan 24, 2024 · A perilymphatic fistula (PLF), also known as a labyrinthine fistula, is defined as an abnormal communication between the perilymphatic space of the inner ear and the middle ear cavity. It usually results in a leakage of perilymphatic fluid into the middle ear through the round window, oval window, or both [ 9 ].

Although a CT scan is the most reliable preoperative method for detection of labyrinthine fistula, the definitive diagnosis is only made intraoperatively (Ikeda et al., 2012). Surgical treatment depends on the localization, size, and depth (bony and/or membranous labyrinth) of the fistula as well as the condition of the other ear.

May 1, 2022 · Subjective hearing loss and vertigo are the most common clinical signs indicating a labyrinthine fistula. We advocate complete removal of the cholesteatoma matrix and covering of the fistula, since iatrogenic sensorineural hearing loss is rare.

Apr 17, 2020 · Labyrinthine fistulae (LF) are caused by abnormal communications between the inner ear and surrounding structures resulting in perilymph leakage and hearing loss. Labyrinthine fistula represents as erosive loss of the enchondral bone overlying the semicircular canals without loss of perilymph.

Oct 22, 2016 · Management of labyrinthine fistula: hearing preservation versus prevention of residual disease. Geerse S, de Wolf MJF, Ebbens FA, van Spronsen EEur Arch Otorhinolaryngol 2017 Oct;274 (10):3605-3612. Epub 2017 Aug 10 doi: 10.1007/s00405-017-4697-2. PMID: 28799140 Free PMC Article.
