Background: Several graft material used  in tympanoplasty operation to repair the perforated tympanic membrane. Our aim of this study is to compare the efficacy of tragal perichondrium and tragal cartilage with perichondrium as graft material

Matetials and Methods: This study was a prospective one, conducted in Malda Medical College  during January 2015 to December 2017, over 60 patients divided in two equal group randomly 30 patients each. One group undergone Tympanoplasty with tragal perichondrium as graft and in the other group we used tragal cartilage with perichondrium as graft material.The data was collected from above patients and statistically analyzed regarding graft taken or rejected and hearing improvement.

Results and Analysis: Underlay tympanoplasty with tragal perichondrium as graft show about 86.67% success rate in respect to drum closure and Tragal cartilage with perichondrium show drum closure in about 80%. Post–operative AIR BONE gap improvement also little better in tragal perichondrium group than cartilage with perichondrium group.

Conclusion: The study showed that both tragal perichondrium and tragal perichondrium with cartilage are good graft material in respect to drum closure and hearing improvement.
