[The stapes reflex in acoustic tumors (92 cas) (author's transl)].
A comparative study of the acoustic reflex in 92 cases of acoustic neuromas and 40 otological syndromes with a normal meatography. There was complete deafness in 22% of the acoustic neuroma cases and 7.5% of the "false neuromas". A deafness less than 75 dB was observed in 72 VIII nerve and 37 "false neuroma cases, where the acoustic reflex was studied: --reflex absent in 29% of VIII nerve and 11% of "false neuromas"; --decay of reflex in 22% of VIII nerve and 5% of "false neuromas"; --non-pathological reflex in 17% of VIII nerve and 30% of "false neuromas". Hearing was preserved post-operatively in 19 cases out of 55 operations (the retro-sigmoid and middle fossa routes). The acoustic reflex without Decay is an element two times more favourable than a reflex with Decay in cases with preserved hearing.
