Abstract

Objectives: The aim of this study is to evaluate the outcomes of meatocanalplasty with free skin grafts in the treatment of canal stenosis. Methods: This was a case series study performed at Ear Nose Throat Hospital of Ho Chi Minh City between March 2020 and August 2022. Results: 32 adults (33 ears) underwent the procedure. Mean time postoperative was 16.2 months. All chief complaints were resolved. Clinical signs were significantly improved after surgery; all patients had no symptoms of tinnitus (p < 0.0001), otalgia (p < 0.0039), otorrhea (p = 0.0156) and facial paralysis (p=1); only 4 patients still had hearing loss after surgery, but the degree of hearing loss was improved postoperatively (p < 0.0001). There were 2 cases of recurrence (6.1%). The hearing results were improved remarkably with the mean air conduction PTA was improved 32dB and the mean air-bone gap was improved 19.5dB postoperatively (p<0.0001). There were no cases of complications after surgery. All donor sites appeared well healed as well as bare bone was cover completely in all cases. Conclusion: Canal stenosis may be easily diagnosed, but its treatment can sometimes be challenging. Surgery is the primary treatment. In addition, a careful and meticulous aftercare is necessary to obtain optimal outcomes.
