Initiation of Endolymphatic Hydrops after Resection of the Endolymphatic Duct / 대한이비인후과학회지

ABSTRACT

While data from animal models have shown endolymphatic hydrops to be developed following the obstruction of the endolymphatic duct, such connection has not yet been established in humans. This study reports on a case of hearing loss at low frequencies, tinnitus and aural fullness after removal of a clival oculomotor schwannoma via retrolabyrinthine approach that included resection of the endolymphatic duct. Commencement of a low salt diet and diuretic medication resulted in almost complete recovery of hearing, although some subtle tinnitus and aural fullness persisted. The clinical outcome supports the appearance of this case to be an evidence of initiation of endolymphatic hydrops due to resection of the endolymphatic duct.
