Abstract
During the 2-year period of 1964–1965, 303 chronic ears were operated at the Oulu Clinic. In 70 cases a myringoplasty or tympanoplasty was made without mastoid bone work, and in 233 cases the radical bone removal was included. For repair of the drum and part of the meatus, temporal muscle fascia was used exclusively, and the cavity was occluded with the musculoperiosteal pedicle flap as advocated earlier. Certain important phases of the tympanic repair are elaborated, and results in various clinical subgroups presented.
