Congenital choanal atresia frequently demands immediate recognition in the newborn, and provision of a nasal airway as soon as possible. A variety of techniques are available to correct this problem, but none is entirely satisfactory. Transpalatal procedures are associated with significant morbidity in the newborn, and transnasal microsurgical procedures are less predictable when a thick bony plate is present in the choanal obstruction. Transnasal resection with the CO2 laser has been carried out in seven patients (ten sides), whose ages ranged from 16 hours to 14 years. From this early experience, it appears that the procedure is entirely feasible and convenient. It seems to have significant advantages over conventional microsurgical techniques. Eight out of ten choanae have remained patent for four months or more. A lumen keeper is needed during the immediate postoperative period for at least two to three weeks. The procedure is associated with minimal morbidity.
先天性后鼻孔闭锁常需在新生儿期立即识别，并尽快建立鼻气道。有多种技术可用于纠正这一问题，但均不尽人意。经腭手术在新生儿中会引发严重并发症，而当后鼻孔阻塞存在厚骨板时，经鼻显微手术的效果更难以预测。已对7例患者（10侧）实施了二氧化碳激光经鼻切除术，患者年龄从16小时至14岁不等。从这一早期经验来看，该手术似乎完全可行且简便。与传统显微手术技术相比，它似乎具有显著优势。十分之八的后鼻孔在术后四个月或更长时间保持通畅。术后即刻至少需要两到三周使用管腔保持器。该手术的并发症极少。
