Abstract:
We present the case of a 56 years old female controlled in our ENT Department because of right sudden hearing loss, tinnitus and vertigo. The endoscopic exam was normal. Audiogram showed a severe neurosensorial hypoacusia and PEATC confirmed the so called hypoacusia suggesting a retrocochlear origin of it.
