Double layer crescent graft technique for endoscopic tympanoplasty

Objectives: The main aim of this study was to present the surgical and functional outcomes of tympanoplasty performed using the crescent graft technique. Methodology: In this research, we used an underlay crescent cartilage-perichondrium composite graft and overlay perichondrium graft to repair tympanic membrane perforation. Pre-operative and post-operative tympanic membrane examinations and hearing evaluations were performed. Results: A total of 155 patients were included in this retrospective study. The pre-operative hearing threshold was 12.95 ± 3.85 dB and the post-operative threshold 5.7 ± 4.1 dB. The improvement was significant (p<0.05). Reperforation was observed in nine patients, graft lateralization in five patients, and graft retraction in four patients at the 1-year follow-up. Conclusion: Double-layer crescent graft tympanoplasty yielded successful functional and hearing outcomes.
