Ear-Canal Exostosis

Ear-canal exostosis (surfer's ear) is benign bony outgrowths in the external auditory canal, bilateral, associated with chronic cold-water exposure. They may cause cerumen trapping and conductive hearing loss if large. Treatment: observe if asymptomatic; keep canal clear; surgical exostectomy/canalplasty if they cause obstruction, recurrent infection, or significant hearing loss.

Common Symptoms

Bilateral canal bony outgrowths; cold-water exposure; cerumen trapping; conductive loss if large

Causes and Pathogenesis

Repeated cold-water exposure induces benign hyperostosis of the canal bone.

Treatment

Observe; keep canal clear; exostectomy/canalplasty if obstructing/infecting

Preventive Measures

Use earplugs swimming; keep canal clear.
