Perbandingan Keberhasilan Miringoplasti Mediolateral Dengan Medial dan Lateral

Abstract

Myringoplasty is a reconstructive procedure to repair timpanic membrane perforation, with mobile ossicular chain, and no pathological tissue in the middle ear cavity. In myringoplasty using lateral graft, the failure are tympanic membrane lateralization and anterior sulcus blunting. In medial graft, the failure is reperforation of the anterior tympanic membrane. Using mediolateral graft technique, as a hybrid from medial and lateral technique, could decrease the failure of the myringoplasty. The objective is to compare mediolateral graft myringoplasty with medial and lateral graft in anterior and subtotal perforation. Methode: A clinical trial and parallel design with three treatments which perform in Eye–ENT Private Clinic in Bandung from January-November 2006. Evaluation was done to see the successful of myringoplasty in anterior and subtotal perforation using transcanal approach with local anesthesia. We observed the result of myringoplasty with mediolateral graft compare with medial and lateral graft that will be achieved if the graft grow completely and increasing of conductive hearing ability _10 db. Result: Of the ninety-nine subject, the successful rate of myringoplasty using mediolateral graft was 100%, medial graft 90.3% and lateral graft 81.8%. Conclusion: Mediolateral technique as good as medial technique but still better than lateral technique.
