Objective: The aim of the present study was to evaluate the surgical and functional results of endoscopic butterfly-inlay cartilage myringoplasty and endoscopic push-through myringoplasty in the treatment of anterior perforation of the tympanic membrane.
Method: This open-label randomised clinical study was conducted on 71 patients with small- and medium-sized anterior perforations of the tympanic membrane. Graft success rate, hearing results, operative time and complications were analysed.
Results: Graft success rates for endoscopic butterfly-inlay cartilage myringoplasty and endoscopic push-through myringoplasty were 94.1 and 91.8 per cent, respectively (p > 0.05). Post-operative air-bone gap values significantly improved in both the endoscopic butterfly-inlay cartilage myringoplasty and endoscopic push-through myringoplasty groups. The average operative time was significantly shorter in the endoscopic butterfly-inlay cartilage myringoplasty group (31.5 minutes) compared to the endoscopic push-through myringoplasty group (41.7 minutes; p < 0.05).
Conclusion: When compared with the endoscopic push-through myringoplasty, the endoscopic butterfly-inlay cartilage myringoplasty technique, which is technically easier to perform, does not require packing and has a shorter operating time. It is a reasonable approach for repair of anterior perforations of the tympanic membrane.
