The authors discuss the different approaches in surgical treatment of choanal atresia. They describe a method of endonasal approach under optic control. In this method an opening in the bony atresia is made via the nasal cavity with the aid of a surgical microscope and micro-instruments, while the posterior wall of the atretic plate is observed by means of a 110 degrees endoscope via the nasopharynx. This method is illustrated by a clinical case, with a four year follow-up.
作者们讨论了后鼻孔闭锁手术治疗的不同方法。他们描述了一种在视神经控制下的鼻内入路方法。在这种方法中，借助手术显微镜和微型器械通过鼻腔在骨性闭锁处制造开口，同时通过110度内窥镜经鼻咽观察闭锁板的后壁。通过一个临床病例及四年随访对该方法进行了说明。
