Endoscopic Type I Tympanoplasty in 70 Patients with Chronic Otitis Media: A Preliminary Report
Keywords:Chronic otitis media, type I tympanoplasty, endoscopic, post-operative pain, tympanic membrane perforation, hearing, morbidity
Objective: To evaluate the preliminary surgical results of Endoscopic Type I Tympanoplasty
among patients with inactive chronic otitis media without ossicular pathology.
Design: Prospective Series
Setting: Tertiary Government Hospital
Participants: Seventy patients with inactive mucosal chronic otitis media (COM) with air bone gap (ABG) of ≤ 40 dB on the preoperative audiogram scheduled to undergo Type I Tympanoplasty between July 2018 and December 2020 were enrolled.
Results: Seventy-three (73) ears were evaluated. The overall rate of graft uptake was 95.9% at 12 weeks. There was a statistically significant (p<.001) improvement in hearing on comparison of pre-operative (25.74 ± 7.34 dB) and post-operative (14.82 ± 6.55 dB) air bone gap. The duration of surgery was less than one hour in 76.7% and 77.2 % patients experienced only mild postoperative pain.
Conclusion: Endoscopic tympanoplasty can provide good results with respect to graft uptake and hearing gain with short surgical duration and minimum postoperative morbidity. Longer follow up of at least 6 months (for graft uptake) and preferably not less than 12 months (for hearing results) may confirm our preliminary findings
