Objective: The tympanomeatal flap elevation technique has been used in tympanoplasty for decades; however, this procedure has disadvantages. In recent years, endoscopic transcanal myringoplasty (ETM) has been increasingly practiced and has yielded positive results.This study compares the efficacy of ETM and endoscopic type I tympanoplasty (ETT) in repairing medium-sized perforations of the tympanic membrane. Methods: This retrospective medical record review included patients undergoing surgery for medium-sized perforations of the tympanic membrane from January 1, 2013 to August 1, 2015. We divided our patients into 2 groups: the ETM group and ETT group. The main outcome measure was comparison of the graft take rates and hearing results between ETM and ETT. Results: A total of 113 patients were enrolled in this study; of these patients, 64 underwent ETM and 49 received ETT. The overall graft take rates and improvement of air-bone gaps were comparable between the groups. However, the patients in the ETM group had shorter operative times and fewer follow-up visits over 3 months than those in the ETT group did. Conclusion: We recommend that ETM (instead of ETT) be used for repairing medium-sized perforations of the tympanic membrane.
