摘要
Abstract
Objective To review results of myringoplasty using a surgical technique to restore the anterior tympano-meatal angle as well as the shape of reconstructed tympanic membrane. Methods Myringoplasty was performed on 64 ears (35 males and 29 females) using an underlay/overlay graft technique, with a slit cut in the graft to accommodate the malleus handle. All patients had a history of otitis media of no less than 3 years. Patients were followed up for 8 months - 3 years. Results The reconstructed tympanic membrane healed in 95.3% (n=61) of the cases, with satisfying anterior tympanomeatal angle and tympanic membrane shape in 51 cases.. Acoustic impedance test in the 45 cases followed up for more than 2 years showed that static compliance value was > 1.0 ml in 25 cases, and < 1.0 ml in 20 cases. Tympanogram was with type A in 36 cases, type B in 3 cases, and type C in 6 cases. PTA on audiogram improved by 15 dB on average. Conclusion The underlay/overlay graft technique with a slit in the graft to accommodate the malleus handle used in this study appears to offer improved restoration of the anterior tympanomeatal angle and the shape of the reconstructed tympanic membrane in myringoplasty, which is considered an important factor affecting treatment outcomes.关键词
