title: Ear canal hyperostosis--surfer's ear. An improved surgical technique.
abstract: The increased populatiry of surfing has produced a marked augmentation in the incidence of ear canal exostosis. However, when it becomes moderately severe, I prefer to call it "hyperostosis." Exposure to cold ocean water for many years can be an important etiologic factor in hyperostosis. There is a serious risk, and a high incidence of tympanic membrane perforations during the removal of large external canal hyperostosis. This injury can be prevented by placing a sheet of Silastic against the tympanic membrane beforehand. I describe the method. Serious degrees of hyperostosis, causing transient hearing loss and otitis externa, are increasingly common in coastal towns, where cold-water surfing is a popular year-around sport.
