ABSTRACT

A clinical study for 604 cases of the traumatic perforation of the tympanic membrane (TM) was made, treated in a Department of Otolaryngology, National Police Hospital between January 1988 and July 1991. The TM perforation of left side was 4.5 times as of right side. The majority of the perforation were due to hand slap(74.5%). The patients visited the hospital after trauma within three days in about 60% of patients. The size of the perforation involved 25% or less of the pars tensa was 491 cases(81.3%). The location of the perforation was usually present at the antero-inferior quadrant in 236 cases(39.1%). The shape of the perforation was round to oval, or slit to triangular in about 80%. The followed 191 cases determined the time required for spontaneous healing of the traumatic perforation to occur : 97 cases(50.8%) healed in approximately one month; 37 cases(l9.4%) in approximately two months ; 11 csaes(5.8%) in approximately three months ; 27 cases(l4.1%) in four months or longer. The overall spontaneous healing rate was 90.1% in 172 of 191 follow-up cases. Larger perforations were less likely to heal spontaneously.
