OBJECTIVE: The objective of this study was to evaluate the graft success rate and hearing outcome of modified cartilage inlay graft technique for repairing large perforations under local anesthesia.
STUDY DESIGN: Prospective case series.
METHODS AND MATERIALS: We performed a prospective study in 31 patients with large perforations who underwent endoscopic local anesthesia-based modified cartilage inlay graft technique with no raising of the squamous epithelium and no rimming of the perforation margins. The graft outcomes and complications were evaluated at 6 and 24 months postoperatively.
RESULTS: Thirty-one patients (31 ears) were included in this study. The mean operation time was 42.3 ± 2.6 (ranged 36-51) minutes. The visual analog scale pain scores at intraoperative and 2 and 48 hours postoperatively were, respectively, 2.6 ± 0.6, 1.4 ± 0.2, and 0.6 ± 0.1. The graft success rate was 100.0% (31/31) at 6 months after surgery. However, only 25 (80.6%, 25/31) patients completed a 2-year follow-up and performed a temporal bone CT examination; re-perforation was seen in 2 patients, the graft success rate was 92.0% (23/25). CT revealed the well-developed pneumatization of the mastoids and middle ear in all the patients. Nevertheless, 1 (1/25, 8.0%) patient developed a graft epithelial inclusion cyst, which was removed by endoscope in the outpatient setting. The mean preoperative air bone gap (ABG) was 23.1 ± 4.3 dB, while the mean postoperative ABG after 6 months was 14.9 ± 2.6 dB; the difference between these values was significant (P < .05; Wilcoxon's signed-rank test), and the functional success rate was 93.5% (29/31).
CONCLUSION: Endoscopic modified cartilage "inlay" graft technique with no raising the squamous epithelium and no rimming the perforation is a minimally invasive technique with a short operative time and satisfying success rate for closure of large perforations under local anesthesia.
