Exostoses of the external ear canal

Timothy C. Hain, MD Page last modified: April 30, 2016

Exostoses are bumps in the bone under the skin of the external ear canal. They are generally harmless, and are not prone to grow to sizes large enough to cause serious disturbance. Exostoses are traditionally attributed to "cold water swimming". While there seems to be some correlation with swimming (Castro et al, 2016), neverthless many individuals have these bumps and deny being a member of either the Navy Seals or the polar bear club.
