Fat Graft Myringoplasty versus Chemical Cauterization in Small Tympanic Membrane Perforation:A Comparative Study

Introduction : Tympanic membrane perforation is mostly due to infection, trauma or post tympanostomy tube insertion. A variety of autografts have been used for closure of tympanic membrane perforation such as perichondrium. temporalis fascia, cartilage fat, platelet rich plasma, and chemical cauterization. Material and Method : A Prospective, Comparative and Randomized study . Eighty Patients visiting E.N.T Outpatient department at tertiary care center were selected fulfilling the inclusion criteria and exclusion criteria. Results : Out of 43 patients in fat graft myringoplasty, the surgery was successful in 39 (90.70%) patients. However, the success rate in chemical cauterization was found to be 88% (in 37 out of 42 patients). Overall success rate is 89.40% (in 76 out of 85). Conclusion : Fat graft myringoplasty and chemical cauterization are strongly recommended for closure of small tympanic membrane perforations; however multiple sittings are required for chemical cauterization
