Exostectomy (surfer’s ear surgery)

What is exostectomy?

Exostoses are bony growths that grow inside the ear canal due to long term exposure to cold water or wind. It is most common among swimmers and surfers. Exostectomy is surgery to remove the bony growths and widen the ear canal.

Why have this procedure?

Exostoses grow slowly over time. When they reach a certain size, they may block the ear canal causing water and debris to get trapped inside. Having a blocked ear canal can cause problems with repeated ear infections and hearing loss. An exostectomy procedure can remove the exostoses and widen the ear canal. 

What is involved in this procedure?

Exostectomy is performed in hospital under general anaesthetic. The operation usually takes between 2-3 hours

Your ENT surgeon will make a small incision, usually behind the ear in the hairline or at the top of the ear canal entrance. An operating microscope will be used to remove the bony lump while preserving the delicate skin of the ear canal. The ear canal will be widened before dressings are packed inside.

What should I expect after surgery?

After surgery, you’ll have a medicated pack in the ear canal for two weeks. Ear drops will stop the pack from drying out and help prevent infection. It’s important to avoid getting the ear wet. Most people take 1-2 weeks off work while they recover.

Where will I have my surgery?

Exostectomy is performed in hospital. Most people will stay overnight following this procedure.

If you have private health cover, you can choose to have the surgery at North Shore Private Hospital, Castlecrag Private Hospital or Northern Beaches Hospital. If you prefer to be seen as a public patient, surgery is offered at Northern Beaches Hospital.
