Sudden sensorineural hearing loss (SSHL) is a rapid loss of (inner ear) hearing ability and should be treated as a medical emergency. Sensorineural hearing loss occurs when there is damage to the inner ear (cochlea) or auditory nerve, but unlike labyrinthitis, patients with SSHL do not suffer vertigo. According to its classic definition, SSHL develops within 3 days and only one ear is affected > 90% of the time. This disease can have many causes including infection, trauma, vascular problems, neurological diseases, & retrocochlear mass lesions; however, most often, SSHL remains idiopathic (cause unknown). While\u00a0autoimmune ear disease<\/a>,\u00a0ototoxic\u00a0medications, and systemic diseases can initially present with single sided hearing loss, they typically progress to affecting both ears within a few weeks to months.<\/p>\n\n\n\n

When patients experience a sudden change in auditory function, a skilled ear exam and comprehensive audiogram are required as soon as possible. It is critical that the type of hearing loss (conductive, sensorineural, or mixed) be defined rapidly so that appropriate workup and treatment can be initiated.<\/p>\n\n\n\n
