Endoscopie versus microscopie myringoplasty: A comparative study.

Tympanic membrane perforation in a common problem that otolaryngologist encounter in day to day practice requiring tympanoplasty or myringoplasty. The cause of tympanic membrane perforation is either trauma, infection, or iatrogenic. The incidence of tympanic perfo ration in United States is 1 to 3% in lifetime. Objective: To compare endoscopic versus microscopic myringoplasty in terms of graft success, operative time, pre and post operative Air bone gap. Material and Methods: To compare the results of myringoplasty using operating microscope (post aural) with endoscopic approach (permeatal). This retrospective comparative study was conducted in department of ENT in DHQAbbottabad after approval from ethical committee for a period of three years from January 2019 till December 2021. A total of 80 patients age group from 18 till 70 with tympanic membrane perforation were included in study. Results: 80 patients were included in study. 40 patients in each group. The mean age in group A was 44.63±13.83 years while in group B it was 46.20±12.09 years. Graft success rate was 95 percent in endoscopic approach while 92.5% percent in microscopic group with a p value of 0.64. The pre-operative mean air bone gap was 24.15 db and 23.08 db, improved to 10.23db in endoscopic group and 9.2 db in microscopic group (p > 0.05). Conclusion: In our study graft success was comparable in both groups. The surgical success rates were 95% in Group A and 92.5% in Group B. No differences in the mean decrease in the air-bone gap between two groups. Significant postoperative hearing improvements were evident in both groups. The mean operative time was lesser in case of endoscopic approach. [ABSTRACT FROM AUTHOR]
