Two cases of congenital bony stenosis of the nasal piriform aperture (anterior nares) are presented. Both patients experienced episodes of respiratory distress and clinical symptoms similar to those seen in patients with posterior choanal atresia. The underlying anatomic abnormalities in congenital bony inlet stenosis are quite different from those in choanal atresia and require different surgical approaches for correction. Computed tomography demonstrates in detail the underlying anatomic abnormality and allows differentiation of bony inlet stenosis from choanal atresia.
本文报告两例先天性鼻梨状孔（前鼻孔）骨性狭窄病例。两名患者均经历过呼吸窘迫发作，且临床症状与后鼻孔闭锁患者相似。先天性骨性入口狭窄的潜在解剖学异常与后鼻孔闭锁截然不同，需要采用不同的手术方法进行矫正。计算机断层扫描详细显示了潜在的解剖学异常，并能区分骨性入口狭窄与后鼻孔闭锁。
