ASSESSMENT OF OUTCOME OF TYMPANOPLASTY TYPE-1 ON HEARING AND CONTRIBUTING FACTORS
Aim:To assess the effect of size of perforation on the hearing loss and on the degree of improvement after myringoplasty. Materials and methods: In the present study a series of 100 patients of Tympanoplasty Type I, done by postaural underlay technique using temporalis fascia were studied over a period of 18 months (May 2019 to May 2020). Age of the patient ranged from 10-50 years with an average of 24.9 years. Out of 100 cases 41 were males and 59 were females. The average length of time the ear remained dry prior to surgery was 14 months ranging from 2 months to 6 years. Result:It was seen that the size of the perforation signicantly affects the degree of hearing loss and degree of subsequent improvement after Tympanoplasty Type I; large and medium size perforation had greater hearing loss and greater postoperative hearing improvement compared to small perforations which was statistically signicant (P<0.05). Conclusion: The only factor which signicantly inuenced the hearing outcome post operatively is the size of the perforation. The size of the perforation affects the degree of hearing loss and degree of subsequent improvement after Type I Tympanoplasty; large and medium sized perforations had a greater hearing loss and greater post operative hearing improvement compared to small perforations.
