Bilateral choanal atresia presents as neonatal respiratory distress and suckling difficulty. Definitive repair of this anomaly by both transpalatine and transnasal approaches had been effective in young children. The transnasal procedures are preferred in infants because of the shorter operative time, low morbidity, and minimal potential for damage to developing structures. Fourteen children were treated for bilateral choanal insufficiency.
双侧后鼻孔闭锁表现为新生儿呼吸窘迫和吸吮困难。通过经腭和经鼻入路对这种异常进行确定性修复对幼儿有效。由于手术时间短、发病率低且对发育中结构的损伤可能性最小，经鼻手术在婴儿中更受青睐。14名儿童接受了双侧后鼻孔闭锁不全的治疗。
