Functional hearing loss presenting as sudden hearing loss: a case report.
A case of functional hearing loss presenting as sudden sensorineural hearing loss in the only hearing ear of a musician is presented. Pure-tone audiometric evaluation showed good intratest and intertest consistency. The pitfalls of diagnosis, ultimately made by brain stem evoked response audiometry, are discussed in light of the literature on sudden and functional hearing loss. Psychiatric evaluation revealed features consistent with hysterical conversion. It is argued that it is important to establish the exact etiologic agent of functional hearing loss despite the difficulty of diagnosis so that the patient may receive appropriate treatment.
