During the past 3 years 62 patients were treated for traumatic perforation of the tympanum.1) The chief complaint was mainly earache or bleeding from the ear if the perforation was due to direct injury during removal of earwax.On the other hand, many patients with indirect injuries, such as those due to a slap on the cheek or the ear, had a sensation of ear-fullness or hearing impairment.2) Many of the patients were in the second decade of age, and in these perforation was apt to be due to a slap on the cheek or the ear.3) In 34 patients the perforation was in the antero-inferior part of the eardrum, and in 6 in the postero-inferior part.4) Spontaneous healing, that is, closure of a perforation smaller than one fourth of a quadrant of the eardrum, usually occurred within about 9 days.Large perforations, one fourth to one half of a quadrant, required about 16 days to heal.Very large perforations, one half to one quadrant in size, needed about 24 days to heal.5) Hearing acuity seemed to be related to the size and location of the perforation.6) The procedures and planning of therapy at our ENT clinic are discussed.
