A double-blind, randomized study is described involving a total of fifty-five patients suffering from eczematous external otitis comparing for efficacy hydrocortisone alcoholic solution and hydrocortisone-17-alpha-butyrate. The trial duration was seven days. No difference in efficacy could be demonstrated between the two preparations. No side-effects were observed.
