Ear Exostosis (Surferâs Ear) â Severe (Grade 3): Extensive bony growth, often > 67% canal obstruction; the ear canal may be nearly blocked.
Overview:
Ear exostosis is a benign bony growth that develops in the ear canal. It is most commonly associated with repeated exposure to cold water and wind, which is why it is often nicknamed âsurferâs ear.â
What Happens:
   â˘Â   Bony lumps gradually form inside the ear canal.
   â˘Â   These growths can narrow or block the canal.
   â˘Â   This can trap water, earwax, and debris, leading to repeated ear infections and hearing issues.
Causes:
   â˘Â   Chronic exposure to cold water or cold air.
   â˘Â   Common in surfers, divers, swimmers, and people who frequently participate in cold-water sports.
Symptoms
   â˘Â   Decreased hearing
   â˘Â   Feeling of fullness in the ear
   â˘Â   Frequent ear infections
   â˘Â   Water or wax getting stuck in the ear
   â˘Â   Occasionally discomfort or pain
Diagnosis
   â˘Â   Typically diagnosed by an Audiology or ENT specialist using an ear examination (otoscopy).
Treatment:
   â˘Â   Mild cases: monitored or managed with ear protection (earplugs, drying drops).
   â˘Â   Severe cases: may require surgical removal of the bony growths to restore normal ear canal size and function.
Prevention:
   â˘Â   Wearing earplugs or a wetsuit hood in cold water environments
   â˘Â   Avoiding prolonged exposure to cold wind and water.

In summary: Ear exostosis is a preventable and treatable condition caused by repeated cold water exposure, leading to abnormal bone growth in the ear canal. Early prevention is key to avoiding surgery.
