Outcome of different graft materials used in Myringoplasty

Aim: To compare the result of graft materials i.e. temporalis fascia, tragal perichondrium and ear lobule fat in various aspects but the prime interest would be the closure of tympanic membrane perforation and postoperative hearing improvement. Materials and methods: The study was carried out on 60 patients admitted for myringoplasty as per selection criteria in the Department of Ear Nose and Throat for a period of 1 year in patients autogenous graft materials was used and they were divided into three groups. In Group A 20 patients in which termporalis fascia was used as graft, Group B 20 patients in which tragal perichondrium was used as graft and Group C 20 patients in which ear lobule fat was used as graft. Results: Maximum number of patients (41.7%) was in the age group of 21-30 years. Female patients outnumber the male patients. The male female ratio was 1: 2. Rural population was more as compared to urban in study groups. Left ear was more involved in all the groups. Maximum number of patients i.e. in group A (50%), in group B (45%) and in group C (55%) was having duration of ear discharge of 1-5 years. Dry ear of <3 months of duration in group A, group B and group C was 50%, 80%, and 70% of patients respectively. In group A, 50% of patients had more than 30dB AB gap while 45% of group B and 50% of group C had less than 20dB AB gap. Overall total AB gap was 10.33 ± 9.62 dB. Mean improvement in hearing was 12.32 ± 8.42 dB, 10.38 ± 5.73 dB and 12.62 ± 8.06 dB in group A B and C respectively. Conclusion: Temporalis fascia graft has good improvement of hearing when compared to other grafts in study. Ear lobule fat when used in small perforations has encouraging results.
