Acquired sensorineural hearing loss and tinnitus can come about through various etiologies such as exposure to excessively loud noise or drugs with ototoxic properties. As such, acquired hearing loss is a common source of morbidity which deleteriously affects the ability to communicate. At present our ability to detect acquired hearing loss and tinnitus at its earliest stages is limited and there are no adjuncts to audiometric evaluation. The earliest cellular targets of noise and ototoxins in the cochlea are the outer hair cells (OHC). I hypothesize that serum assays of OHC specific protein, prestin, will allow detection and quantification of OHC damage before audiometric testing can identify presence of hearing loss. At present, there are no data available to evaluate this hypothesis, but initial evaluation can readily be carried out using existing experimental animal models of ototoxicity and noise-induced hearing loss. Early detection of OHC damage is critical to adoption of measures aimed at ameliorating hearing loss and tinnitus, thus reducing permanent deficits and disability. (C) 2015 Elsevier Ltd.
