Surfer's ear is the common name for an abnormal bone growth within the ear canal. It is prominent under surfers, divers and people who work in conditions with cold air. Surfer's ear is not the same as swimmer's ear, although infection can result as a side effect.
Surfer's ear will usually not exhibit any symptoms but can cause hearing loss, recurrent infections, discharge, a sensation of fullness in your ear, and recurrent wax impactions. Treatment involves medical management but may include surgery if symptoms become severe.
