Patulous eustachian tube in a case of adolescent anorexia nervosa.

Autophonia, the hyperperception of one's own voice and breathing, is one of the consequences of rapid weight loss and is explained within the syndrome of the patulous eustachian tube. We report on a female adolescent, who presented to an otologist for autophonia and was finally diagnosed with anorexia nervosa. The occurrence and relevance of this symptom in eating-disorder patients is discussed.
