Outcomes of Endoscopic Assisted Versus Microscopic Assisted Type1 Tympanoplasty for Inactive Chronic Otitis Media

Abstract

Background and objectives: The objectives of this study is to assess the outcomes of the endoscope as compared to the microscope in type 1 tympanoplasty surgery for cases with inactive chronic otitis media. Methods: Prospective comparative study was conducted from October 2016 to October 2017, forty patients underwent myringoplasty, twenty were endoscope assisted and twenty were microscope assisted. Results of surgery were compared at the end of six months post-operation. Results: In the endoscope group 85% while in the microscope group 90% of patients had a successful outcome. Average time taken in microscopic myringoplasty was 103.75 minutes range (75 -150 minutes) while time taken in the endoscopic myringoplasty group was 82.25 minutes range (60 -120 minutes). Average hearing gain was 12.25 dB for microscope assisted group and 11 dB for endoscope assisted group. Conclusions: The surgical result of endoscope assisted myringoplasty was similar to the microscope assisted myringoplasty although the graft taken and postoperative hearing gain in microscopic group was better than endoscopic group, but the operation dura-tion in endoscope group was shorter.
