A transnasal approach was employed in 28 neonates (26 blacks and 2 whites) with bilateral choanal atresia. In each patient the atresia was perforated microsurgically with the drill, followed by insertion of a Portex endotracheal tube for a period of three months. By this method a satisfactory nasal respiration was established immediately. Removal of the posterior part of the vomer is crucial to the successful result. During the follow-up, one death was recorded in a microcephalic neonate, unrelated to the operation and another four patients required repositioning of the tube under general anesthesia. We feel that the above technique is simple and definitive with negligible complications.
对28例双侧后鼻孔闭锁的新生儿（26例黑人、2例白人）采用经鼻入路。对每例患者，用钻头进行显微手术打通闭锁，然后插入波特克斯气管内导管，持续三个月。通过这种方法，立即建立了满意的鼻呼吸。切除犁骨后部对取得成功结果至关重要。在随访期间，1例小头畸形新生儿死亡，与手术无关，另有4例患者需要在全身麻醉下重新放置导管。我们认为上述技术简单且效果确切，并发症可忽略不计。
