Abstract:Abstract:ObjectiveTo explore the clinical application of endotoscopic myringoplasty for tympanic membrane marginal perforation in anterior inferior quadrant.MethodsA retrospective study was carried out among 13 patients with tympanic membrane marginal perforation in anterior inferior quadrant, who underwent endotoscopic myringoplasty. The preoperative results of pure tone audiometry and otoscopy were compared with the postoperative ones, and their airbone gap and improvement value were calculated.ResultsAt 3 months after operation, otoscopy showed that the tympanic membrane of all patients were integrity. The mean thresholds of air conduction, bone conduction and airbone gap were (16.0±15.64)dB, (12.16±11.92)dB, and (3.83±3.73)dB respectively. The airbone gap at 3 months after operation was significantly smaller than that before operation(P<0.05).ConclusionWith advantages of simplicity, minimal invasion and satisfied efficacy, endotoscopic myringoplasty is worthy of being widely applied in repair of tympanic membrane marginal perforation in anterior inferior quadrant.
