To the Editor:—
Twenty years ago a 29-year-old white man bumped his forehead slightly when involved in an automobile accident. Except for transient vertigo he suffered no other immediate side effects. X-ray films of the skull and detailed examinations revealed no evidence of injury. Two days after the accident, however, he noticed a clicking in his ears. The clicking was regular at a rate of 110 per minute and was not associated with the pulse or heart beat. No movements of the tympanic membranes, jaw muscles, or soft palate could be observed. This phenomenon was reported in The Journal in 1948.1 I first saw him in 1961. The clicking had disappeared from the right ear several months after it was first noted. The noise was still heard coming from the left ear and has persisted. The rate and intensity remain constant. It can still be heard by medical observers
