Total Endoscopic Perichondrium Reinforced Cartilage Myringoplasty for Anterior Perforation

Abstract

To investigate the outcomes of graft uptake and hearing results in the repair of anterior perforation via a total endoscopic transcanal approach using a single or double perichondrium reinforced cartilage underlay technique. Retrospective study. Tertiary referral hospital. We analyzed 65 patients who underwent surgery for anterior perforation. All surgeries were done via an endoscopic transcanal approach using tragal cartilage as graft, underlay technique reinforced with single or double perichondrium. Two groups were created in which group A had single perichondrium reinforcement and group B had double perichondrium. Graft uptake and hearing outcomes were evaluated between the two groups. During the study period, 65 patients were included, of which 3 were lost to follow-up, and thus, only 62 patients were assessed. As for the surgical outcome, graft uptake was observed in 95.2% (n = 59) of patients, 6 months after the intervention. Graft uptake was not statistically significantly different between groups A and B and was 95% in both. There was a statistically significant improvement in hearing across the series overall, with no significant differences seen between group A and group B. The endoscopic approach for myringoplasty offers superior visualization, especially for anterior perforation avoiding postaural approach and canaloplasty. Endoscopic single or double perichondrium reinforced cartilage underlay technique is a reliable method for repair of anterior perforation. There is no difference in using single or double perichondrium reinforcement. Thus, we recommend using single or double perichondrium reinforcement depending on the need during the surgery.
