Our Experience of Comparison of Hearing Outcomes in Patients Undergoing Type-1 Tympanoplasty with Different Graft Materials

The present study was undertaken to compare the results of various autogenous tissues: temporalis fascia, sliced tragal cartilage and fascia lata as graft materials for type I tympanoplasty in terms of hearing improvement in safe type of chronic suppurative otitis media. A total of 75 cases with central perforation were considered in the study. Of the 75 cases, temporalis fascia graft was used in 25 cases (Group-A), fascia lata graft in 25 cases (Group-B), and sliced tragal cartilage graft in 25 cases (Group-C). The results were evaluated in the form of hearing improvement with respect to the graft materials. A significant association was observed between the groups, that is, temporalis fascia (Group-A), fascia lata (Group-B), and sliced tragal cartilage (Group-C) in terms of improvement in AB gap (P = 0.047). Improvement in AB gap was statistically significant between groups B and A, but not between the other groups. In the present study, fascia lata showed better graft uptake as compared to temporalis fascia and sliced tragal cartilage. The hearing assessment at post-operative 3rd month showed statistically significant hearing improvement with fascia lata when compared to temporalis fascia.
