Comparative study between result of temporalis muscle fascia and tragal cartilage perichondrium as a graft material in type 1 tympanoplasty

Background: Leading cause of deafness in India is chronic suppurative otitismedia. Most common cause of TM perforation is chronic suppurative otitismedia. With this background this study was to compare hearing results, as well as graft takes for commonly preferred reconstruction techniques of the TM (i.e., temporalis fasciavs. cartilage) in tympanoplasty. Methods: The present study consists of 60 cases of C.S.O.M (TTD) which was divided into two groups with 30 cases in each group. In first group type1 tympanoplastywas done by Temporalis fasciatechnique. In second group type 1 tympanoplastydone by tragal cartilage with perichondriumtechnique. History and otoscopicexamination along with pure tone audiometrywas performed preoperatively. Postoperative hearing results and graft uptake were compared between two groups, all surgeries were performed through the post auralapproach. Results: Graft uptake results are better with tragal cartilage with perichondriumtechnique. Hearing improved significantly in both groups. Though this was slightly better in TFT, but not significant statistically. Conclusions: Graft uptake rates are better with the tragal cartilage with perichondriumtechnique in comparison of TFT and hearing results are almost equivalent with both techniques.
