Choanal atresia is a congenital malformation of the posterior portion of the nasal cavity, which is usually unilateral. The incidence is estimated to be 1 in 5,000 to 8,000 live births. Several surgical approaches have been described to correct choanal atresia since Emmert's initial trocar perforation in 1853, including transnasal, transpalatal, transseptal, sublabial transseptal, transantral, and external rhinoplasty. Although the micro-endoscopic transnasal access is a more conservative technique, it allows greater surgical precision, and is currently recommended by many authors; choanal atresia repair is still considered a challenge, with risks of intraoperative and postoperative complications and re-stenosis. This paper reports the results of a series of 33 patients operated via the transnasal micro-endoscopic surgical approach, and describes a new endoscopic technique that the authors call "nasal septal crossover flap technique."
后鼻孔闭锁是鼻腔后部的一种先天性畸形，通常为单侧。据估计，其发病率为每5000至8000例活产中有1例。自1853年埃默特首次进行套管针穿孔以来，已有多种手术方法被描述用于矫正后鼻孔闭锁，包括经鼻、经腭、经鼻中隔、唇下经鼻中隔、经鼻窦和鼻外整形术。尽管鼻内镜经鼻入路是一种更为保守的技术，但它能提供更高的手术精度，目前被许多作者推荐；后鼻孔闭锁修复仍然被认为是一项具有挑战性的手术，存在术中及术后并发症和再狭窄的风险。本文报告了33例经鼻内镜手术治疗患者的系列结果，并描述了一种作者称之为“鼻中隔交叉皮瓣技术”的新内镜技术。
