A retrospective study of traumatic tympanic membrane perforations in a clinical practice

A retrospective study of 227 traumatic tympanic membrane perforations was made. These perforations were treated in a clinical practice of otolaryngology between January 1969 and July 1977. The following conclusions were supported by the data obtained: 1. Larger perforations are less likely to heal spontaneously. 2. Lightning and molten metal injuries are less likely to heal spontaneously. 3. Final healing and hearing results are good regardless of the mode of therapy employed. 4. Spontaneous healing gives better results than early surgical intervention. 5. Infection adversely affects healing in traumatic perforations. Based on information delineated in the paper, a logical plan of treatment for traumatic perforations is presented.
