Abstract

Background: myringoplasty is the surgical procedure performed to repair a perforated tympanic membrane, with the aim of preventing surinfection and restoring hearing ability.
Objectives: evaluating the outcomes of transcanal underlay myringoplasty. Method: non- controlled intervention study; 43 patients underwent transcanal underlay myringoplasty at National Otorhinolaryngology Hospital, from January 2021 to December 2022. Results: the average age was 36.4 years old. Patients with straight and large canalhad a higher prevalence 60.5%. Healing rate of the tympanic membrane after 6 months was 97.7%. One case developedgrade I atelectasic tympanic membrane 6 months after surgery.The post-operative air-bone gap (ABG) was 13±3.4dB compared to the pre-operative onewas21.2±7.4dB. Conclusions:transcanal underlay myringoplasty with surgical microscope has advantages such as a smaller and aesthetic incision, minimal soft tissue dissection and shorter time of
surgery. Well trained surgeons can use this approach for different sizes and locations of perforation with high success rate.
