Endoscopic Broad Palisade Cartilage Graft Without Raising a Tympanomeatal Flap in the Repair of Subtotal Perforation

Abstract

Objective: This study evaluated the outcome of a broad palisade cartilage graft in the repair of subtotal perforation. Study Design: Prospective case series. Materials and Methods: This was a prospective study of 43 patients with subtotal perforations who underwent an endoscopic broad palisade cartilage graft procedure that did not include raising a tympanomeatal flap. The patients were followed up for 6 months. Results: The 43 patients (43 ears) included in this study had a mean operation time of 38.6 ± 7.4 minutes. Five (11.6%) patients were lost to follow-up; 38 (88.4%) completed the 6 month follow-up. The graft success rate in the latter was 92.1% (35/38). Audiological testing showed no sensorineural threshold shift. The mean preoperative air-bone gap (ABG) was 28.4 ± 5.1 dB, while the mean ABG at 6 months postoperatively was 13.6 ± 3.1 dB; the difference between these values was significant (P
