Endoscopic cartilage myringoplasty with the removal of a small rim of the external auditory canal to repair marginal perforations.

ABSTRACT: OBJECTIVE:To evaluate the graft success rate and postoperative hearing gain for marginal perforations using endoscopic cartilage myringoplasty with the removal of a small rim of the external auditory canal (EAC). STUDY DESIGN:Prospective case series. MATERIALS AND METHODS:We performed a prospective study in 41 patients with marginal perforations who underwent endoscopic cartilage myringoplasty with the removal of a small rim of EAC. Patients were followed up for 6?months. RESULTS:Of the 41 patients with unilateral marginal perforation included in this study, the graft success rate was 100% (41/41). The mean ABG improved from 11.31?±?9.71?dB preoperatively to 7.31?±?2.32?dB postoperatively for small-and medium-sized perforations (P?=?0.13); the mean ABG improved from 21.46?±?8.39?dB preoperatively to 9.84?±?2.41?dB postoperatively for large perforations (P?
