A case of exostosis of the external auditory canal is reported. The patient was a 31-year-old man who was an active surfer of 9 years' duration. On examination there was almost total occulsion of the right ear canal and severe bony stenosis of left. Bilateral exostoses were removed surgically and examined by light and electron microscopy. The histopathological appearance revealed lamellated bone structure devoid of a fibrovascular channel. The long period of cold water stimulation was thought to be the most likely cause of exostosis.
