ABSTRACT
Objectives-To compare the outcome of type 1 tympanoplasty in terms of graft uptake rate and hearing improvement in active and inactive variety of COM. Materials and Methods: 50 patients of COM attending ENT OPD of a tertiary care hospital were selected and underwent type 1 tympanoplasty (25 active and 25 inactive mucosal variety) in underlay technique using temporalis fascia and the outcomes were compared. Results: In our study 88% (n=44) patients had overall successful result. The overall success rate for type 1 tympanoplasty in inactive ear (Ti) and in active ear (Ta) were 92% (n=23) and 84% (n=21) respectively. Postoperative hearing 0-10dB was found in 44% (n=11) patients in both the study groups and 11-20dB hearing was found in 36%(n=9) patients with inactive ear and 28%(n=7) patients with active ear. More than 20dB was found in 20% (n=5) cases in inactive ear and 28%(n=7) cases in active ear. Conclusion: The difference of success rate of type 1 tympanoplasty in both study groups in terms of graft uptake and post operative hearing is statistically insignificant(p>0.05).So condition of the middle ear mucosa and presence of active ear discharge does not affect the success rate of type 1 tympanoplasty.
Keywords: tympanoplasty, active variety of COM, inactive variety of COM, graft uptake rate, hearing improvement.
