From 1992 to 1996 six children and one adult woman presented at our clinic with choanal atresia. In four newborns bilateral choanal atresia was found and in two older infants and one adult unilateral atresia was discovered. Although several different techniques for management of posterior choanal atresia (PCA) are described already in the literature, we decided to try a new approach using rigid endoscopes. This techniques enables the surgeon to visualize the whole atresia plate directly and to see the tips of his instruments. Under direct view it is possible to safely remove the bony plate and to allow immediately for an adequate and persistent airway. This technique is less traumatic and minimizes the risks of conventional surgery. Follow-ups after 1, 2 and 3 years still showed remaining opening of the posterior nose and normal physical development. A second surgical intervention was necessary after 9 months in one case of a newborn however, in whom the first procedure was performed as an emergency on the second day of his life.
1992年至1996年期间，有6名儿童和1名成年女性到我们诊所就诊，患有后鼻孔闭锁。在4名新生儿中发现双侧后鼻孔闭锁，在2名较大婴儿和1名成年人中发现单侧闭锁。尽管文献中已经描述了几种不同的后鼻孔闭锁（PCA）治疗技术，但我们决定尝试使用硬性内窥镜的新方法。这种技术使外科医生能够直接看到整个闭锁板，并看到其器械的尖端。在直视下，可以安全地移除骨板，并立即建立足够且持久的气道。该技术创伤较小，将传统手术的风险降至最低。1年、2年和3年后的随访仍显示后鼻孔保持开放，身体发育正常。然而，有1例新生儿在出生第二天作为紧急情况进行了首次手术，9个月后需要进行第二次手术干预。
