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.

An Olympic curl bar is much lighter than a barbell, weighing only 15 to 20 pounds, and is about 47 to 48 inches long. It can, therefore, be used to lift weights less than 45 pounds as well. Maximum weight capacity for most standard curl bars is about 200 pounds. Standard two-arm curl bars have a 1-inch sleeve on each end, and accept any standard weight plates. These are commonly used in home gyms. Olympic curl bars have a 2-inch sleeve, and they're designed to accommodate slightly bigger weight plates that are commonly found in the gyms.
