Bilateral sudden sensorineural hearing loss following non-otologic surgery.

Hearing loss as a complication of non-otological surgery is rare. The majority of described cases have followed cardiac bypass surgery. To date there have been only 25 reported cases of non-otological surgery associated hearing loss (NOSAHL) which have not involved cardiopulmonary bypass. Only two cases of bilateral NOSAHL have been previously described, and neither resulted in permanent severe bilateral hearing deficit. We describe a case of permanent bilateral severe hearing loss following metatarsal pinning in a patient with pre-existing non-operated otosclerosis.
