Noncancerous tumors. Noncancerous tumors may develop in the ear canal, blocking it and causing hearing loss and a buildup of earwax. Exostoses occur in people who swim in cold water, such as scuba divers and surfers. Surfer's ear is a common term for bony exostosis in the ear canal. The most effective treatment for these noncancerous bony tumors is surgical removal. After treatment, hearing usually returns to normal.
