Abstract
Patients [98] with myringoplasty performed during the period 1966-1974 were studied. Fascia from the temporal muscle was used as the graft material. Patients were invited to follow-up examination on a random basis, the follow-up period ranging from 3-12 yr: 45% of the patients had a follow-up period of 3-5 yr, 49% of 5-10 yr and 6% over 10 yr. The etiology of the tympanic membrane perforation was infectious in 85% of cases, traumatic in 13% and unknown in 2%. Preoperatively, the perforation was evaluated as small in 15%, medium-sized in 48% and large in 37% of the cases. Preoperative pure tone audiometry for air conduction at 500, 1000 and 2000 Hz frequencies revealed 0 dB in 2%, 1-10 dB in 32%, 11-20 dB in 35%, 21-30 dB in 24% and 31-40 dB in 7%. An intact tympanic membrane was found on otomicroscopy at the follow-up examination in 88% of cases. The tympanic membranes were evaluated as follows: 63% normal, 10% too thick, 8% slightly too lateral, 4% blunting of the anterior meatal angle, 1% adherent and 1% baggy. The average hearing for the frequencies 500, 1000 and 2000 Hz were 0 dB in 36%, 1-10 dB in 38%, 11-20 dB in 13%, 21-30 dB in 9% and 31-40 dB in 4%. A hearing result of 30 dB or better was achieved in 96% of the patients. In 74% the hearing loss was less than 10 dB. In 9 of 10 cases permanent healing of the tympanic membrane was found after a long follow-up period.
