Exostosis Repair

Indications for Surgery

Infection, Hearing Loss, Water or Debris Trapping from Exostoses (boney growth of the external auditory canal) are all indications that you may need surgery.


This procedure requires General Anesthetic.

Surgical Time

The length of this procedure is 1 to 2 hours.

Hospital Admission

A hospital admission is not required, your procedure will be done on an out patient basis.

About the Procedure

An incision behind the ear allows access to the boney growths. A diamond drill is used to remove the growths, restoring the normal contour of the external auditory canal.

Side Note

This disorder is associated with chronic cold water exposure. Techniques developed at CEI allow preservation of the canal skin and reduces “time out of the water” for surfers to a minimum.
