Choanal atresia is a congenital absence of communication between the nasal cavity and nasopharynx. Bilateral Choanal Atresia usually present immediately after birth and in the neonatal period. We report an unusual case who presented at the age of twenty two years. This case was successfully managed by a transnasal approach. Choanal atresia should be considered as a rare diagnostic possibility in any patient who presents with total nasal obstruction and persistent mouth breathing.
后鼻孔闭锁是鼻腔与鼻咽之间先天性的不通畅。双侧后鼻孔闭锁通常在出生后及新生儿期立即出现。我们报告一例罕见病例，患者22岁时发病。该病例通过经鼻入路成功治愈。对于任何出现完全性鼻阻塞和持续性张口呼吸的患者，都应考虑后鼻孔闭锁这种罕见的诊断可能性。
