Purpose: The purpose of this research is to study the role of tissue glue (TISSEL) in overlay tympanoplasty when compared with the conventional overlay method. Study design: A prospective randomized comparative study was carried out at the ENT department of Base Hospital, Delhi, in which 60 patients with dry central perforation underwent overlay tympanoplasty. Out of these, 30 underwent conventional overlay tympanoplasty (control) and in the rest of the 30, overlay tympanoplasty was done with the use of tissue glue (cases). Results: Graft take-up rate in control is 90% and in cases 96.7% (p > 0.05). Hearing improvement within 20 dB of A–B gap (at 03 months) in control is 86.70 and 96.70% in cases (p > 0.05). Early hearing improvement (at 6 weeks) in cases was better when compared with the control (p < 0.05). The complication rate in cases is 10% with residual perforation in 01 patient, while that in control is 16.66% with residual perforation in 03 patients (p > 0.05). Conclusion: Graft take-up rate in hearing improvement was found to be better in overlay tympanoplasty with the use of tissue glue when compared with the conventional method with no statistically significant difference. The only significant advantage with the TISSEL group was found to be an early hearing improvement at 6 weeks. Tissue glue (TISSEL) was found to be safe and effective.
