Chemical treatment of external otitis

From 1962 through 1969, 2,008 cases of external otitis were treated chemically. The auditory canal was cleaned and a gauze wick saturated with 20% silver nitrate solution was introduced. The next day the wick was replaced with one saturated with Burow's solution. After two to three days, this wick was removed and the canal cleaned. Results were excellent in 1,593 cases, good in 398 cases, and poor in 17 cases.
