The exostosis of the external auditory canal is a growth of the bone of the duct that is narrowing it more and more. It is a problem that affects people who are in continuous contact with water, especially with cold water. This is why it is also known as the surfer's ear, the swimmer's ear or the diver's ear.

Symptoms of exostosis of the external auditory canal

The main symptom is plugging of the ear after bathing, repetitive otitis and, in more severe cases, hearing loss by complete closure of the duct.

Treatment of exostosis of the external auditory canal

Generally, this disease belonging to the field of otorhinolaryngology is treated with conservative measures, that is, with periodic cleanings of the duct. However, there are cases where the symptoms are more severe or recur more often because the caliber of the duct is very small and surgery is needed to increase the diameter of the duct. This operation resolves the symptoms and gives the duct a normal gauge.

Benefits of the minimally invasive technique for the exostosis of the external auditory canal

In the majority of centers where this surgery is performed it is done behind the auditory pavilion with a milling with drills of different caliber to open the conduit again. Currently there is a new minimally invasive technique that consists of operating through the duct and without having to open behind the ear. With this technique the postoperative is much more bearable, it lacks scars, the recovery is much faster and the patient can re-practice water sports in less than a month.
