Abstract
A case of stapes gusher with monopode stapes was reported. A 14-year-old boy with right progressive and left non-progressive deafness was admitted in our clinic on January-9, 1973. Audiometry of the patient revealed right pure conductive deafness and left combined deafness, but the threshold of left ear could not be decided because of right severe conductive deafness. The left ear was explored and the stapes was found to be monopode stapes. The footplate was small and fixed on the oval window. It had also a small fistula at the center of the footplate covered with normal mucous membrane. Immediately after manuplation, cerebrospinal fluid of in total 250m1 leaked out from the fistula. Stapedectomy was performed and the fluid leakage was controlled by packing the oval window with a teflon-piston wrapped with fascia.
Eight months after, the right ear was explored and fixed monopode stapes like the left was found. In order to avoid the labyrinthine damage, stapes mobilization was performed with good restoration of hearing. But the hearing loss relapsed again in 4 months. Finally stapedectomy with teflon-piston was performed without any complications such as stapes gusher. The hearing recovered to the normal range. Some clinical problems, especially on the stapes gusher, cerebrospinal fluid leakage and the indication of stapedectomy in congenital anomaly, were discussed.
