Endoscopic butterfly cartilage myringoplasty: our long term results

Abstract

Background: Myringoplasty is one of the treatments used for perforated tympanic membrane. Aim/objective: We aimed to evaluate the long-term anatomical and functional outcomes of patients who underwent endoscopic inlay butterfly cartilage myringoplasty. Material and methods: We retrospectively analyzed 74 patients who had undergone endoscopic butterfly cartilage myringoplasty were followed for at least five years. The evaluation included age, sex, duration of follow-up, perforation location, size, preoperative and postoperative pure tone audiometry thresholds (years 2 and 5), air-bone gap, follow-up complications, and postoperative graft and tympanic membrane status. Results: The study included 74 patients with a mean follow-up duration of 76.7 months (range: 60–125 months). The graft success rates were 89.1% at two years and 82.4% at five years postoperatively. There was a significant improvement in air conduction thresholds when comparing preoperative levels to those at two and five years postoperatively (p = 0.003). The air-bone gap showed a significant reduction from preoperative levels to those observed at two and five years postoperatively (p < 0.0001). Conclusion and significance: Our study demonstrates that endoscopic butterfly cartilage myringoplasty is safe and effective for achieving long-term anatomical and functional success. We recommend extending the follow-up period to five years with additional annual assessments thereafter.
