A Study of Graft Uptake and Hearing Improvement in Cartilage Tympanoplasty

Abstract

BACKGROUND To evaluate the effectiveness of Cartilage as a grafting material in terms of graft uptake and postoperative hearing following Type I Tympanoplasty. Tympanoplasty is a procedure to eradicate disease in the middle ear and to reconstruct the hearing mechanism, with or without tympanic membrane grafting commonly due after chronic otitis media and trauma. MATERIALS AND METHODS 100 subjects were enrolled for the study for a period of 1 1/2 Years from 2015 to 2017 June. All patients between 15 to 60 Years having mucosal type of CSOM with central, subtotal perforation and conductive hearing loss <45dB underwent cartilage Tympanoplasty. Patients were reviewed on 8th Postoperative day 6th and 12th Postoperative week. The graft uptake and postoperative hearing were evaluated. Statistical analysis was measured in terms of percentage and preposition. RESULTS The graft uptake on 42nd and 90th Postoperative day was 87.7% and 86.6% respectively. The results were statistically significant. The difference of mean preoperative 42nd and 90th Postoperative air bone gaps were 30.11 ± 1.66 dB, 18 ± 1.5db. CONCLUSION The cartilage was found to be excellent grafting material in terms of both graft uptakes and hearing results after type I tympanoplasty.
