Comparison of Graft Uptake Between Temporalis Fascia Versus Tragal Perichondrium in Myringoplasty

Abstract

Background:

Myringoplasty is a gold standard for the mucosal type of COM. This study was done to compare the graft uptake and hearing result after myringoplasty using temporalis fascia graft or tragal perichondrium graft in diagnosed patients of chronic otitis media mucosal inactive.

Methods:

It’s a prospective comparative study including patients with chronic otitis media mucosal inactive above the age of 15 years undergoing myringoplasty and able to come for follow-up. 60 cases were included and randomly divided into two groups. 30 were in temporalis fascia graft group and 30 in tragal perichondrium graft group. Then, graft uptake and hearing results were evaluated in three months postoperatively.

Results:

Out of total patient, graft uptake rate in tragal perichondrium graft group was 28 in number and in temporalis fascia graft group was 27 in number at the end of 3 months after myringoplasty. The difference in graft uptake rate was not significant (p = 1). Mean preoperative Air conduction threshold was 30.1dB and 28.9dB, postoperative was 26.1 dB and 25.2 dB. Mean preoperative Air bone gap was 23.8dB and 25.6dB and postoperative was 15.2 dB and 16.1 dB in temporalis fascia graft group and tragal perichondrium graft group respectively. Both air-conduction thresholds and air–bone gaps showed a statistically significant improvement after surgery. However, when the two groups were compared with each other, there was no statistically significant difference in hearing outcomes.

Conclusions:

There was no difference between graft uptake rate and hearing outcome in temporalis fascia graft group and tragal perichondrium graft group.
