Evaluation of different graft material in type 1 tympanoplasty

Abstract

Aims and Objective: The present study was undertaken to compare the results of various autogeneous tissues temporalis fascia, tragal perichondrium, and fascia lata as graft materials for the type 1 tympanoplasty. Materials and Methods: A total of 120 cases with large, subtotal and total perforation were considered in the study. Of the 120 cases, temporalis fascia graft was used in 60 cases (Group-I), tragal perichondrium graft in 40 cases (Group-II), and fascia lata graft in 20 cases (Group-III). The results were evaluated in the form of rate of graft success, hearing gain, and mean residual air-bone gap with respect to the graft materials. Results and Observation: A nonsignificant association was observed between the groups, that is, temporalis fascia (Group-I), tragal perichondrium (Group-II), and fascia lata (Group-III) and the graft uptake. (P = 0.96 > 0.05) and air bone closure (χ2 = 2.908, P = 0.059 > 0.05). Conclusion: The graft take-up rate and Hearing improvement are similar for the different graft materials used. Size of the perforation doesn't significantly influence the success rate of tympanoplasty as per our study. Normal translucent appearance of neotympanum in the postoperative period was seen only with temporalis fascia, while in tragal perichondrial and fascia lata grafts the neotympanum was whitish, thicker, and translucent to opaque.
