Background: Since the introduction of tympanoplasty in the 1950s, variety of surgical techniques has been developed for closure of tympanic membrane perforation. Tympanoplasty and myringoplasty are commonly used procedures for the treatment of chronic otitis media.
Objective: The aim of the present work was to compare the success rate between endoscopic and microscopic tympanoplasty through transcanal approach as regard improvement of hearing, closure of tympanic membrane perforation and the time of operation.
Patients and Methods: This prospective study was carried out on thirty patients who attended to outpatient clinic of Al-Hussien University Hospital from November 2018 to June 2019. All patients with the complaint of discharging ear and decreased hearing were screened. They were divided randomly into two equal groups; group A was treated by transcanal endoscopic tympanoplasty, and group B was treated by transcanal microscopic tympanoplasty. All operations were done at AL-Azhar University Hospitals (Al-Hussein University Hospital).
Results: The graft success rate was 80 % in group A, and 73.3 % in group B. There was significant improvement in hearing in both groups pre- and post – operatively, but the difference between both groups was not statistically significant. Microscopic tympanoplasty was shorter than endoscopic with no significant difference between both groups.
Conclusion: Tympanoplasty is an effective technique for recovering hearing thresholds secondary to a tympanic membrane perforation. In transcanal approach, postoperative cares were easy as the technique is minimally invasive in surgical approach, scar, bleeding and pain. The telescopic wide angle magnified view of the endoscope overcame most of the disadvantages of the microscope. Endoscopes provided good exposure of the tympanic membrane, usually without canaloplasty.
