2015 Hearing & Balance

Central auditory processing disorders

Because of the extensive bilateral connections of the auditory system,

  • the only way to have an ipsilateral hearing loss is to have a peripheral lesion  i.e., at the cochlea, auditory nerve or cochlear nucleus

  • bilateral hearing loss from a single lesion is invariably due to a lesion located centrally

N.B. Noise exposure, ototoxic drugs and congenital malformations can cause simultaneous damage bilaterally (considered to be multiple lesions).
