title: Homograft tympanoplasty: graft material effects on otoadmittance and audiometric measurements.
abstract: Otoadmittance measurements and air- and bone-conduction thresholds were obtained for 20 subjects who underwent type I tympanoplasty. Component tympanometry, particularly with a high-frequency probe tone, demonstrated that homograft tympanic membrane transplants exhibited more normal function than did temporalis fascia grafts. Audiometric results revealed greater hearing improvement by the homograft transplant group.
