Exostosis, otherwise known as Surfer’s Ear, is an abnormal bone growth within the ear canal. The condition is so named due to its prevalence among cold water surfers. Exostosis symptoms include a decrease in hearing sensitivity possibly combined with an increased prevalence of ear infections. Early symptoms include water trapping in the ear canal.

Causes of Exostosis

Irritation from cold wind and water exposure causes the bone surrounding the ear canal to develop lumps of new bony growth which constrict the ear canal. Where the ear canal is actually blocked by this condition, water and wax can become trapped and give rise to infection.

Treatment of Exostosis

Hearing loss, pain and ear infections may become chronic and severe requiring surgery. Surgery usually requires an incision behind the ear and the exostoses are removed using a drill.
