Evaluation of Different Graft Materials (Temporalis Fascia, Tragal Perichondrium, and Vein Graft) in Type 1 Tympanoplasty

Aims and Objective: The present study was undertaken to compare the results of various autogenous tissues temporalis fascia, tragal perichondrium, and vein 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 vein 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 venous graft (Group-III), and the graft uptake (P = 0.96 0.05) and air-bone closure (chi(2) = 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 does not 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 and venous graft, while in tragal perichondrial, the neotympanum was whitish, thicker, and translucent to opaque.
