To determine the dimensions of the nasal cavity in infants with congenital pyriform aperture stenosis (CPAS).
The nasal cavities of seven children with CPAS were identified and were compared to the nasal cavities of 13 neonates (<30 days old) who had received CT scans for other indications.
The width of the nasal cavities was measured at the pyriform aperture, choana, and at two standardized points along the lateral nasal wall (LW-1 and LW-2) between the pyriform aperture and choana.
Comparison between neonates with and without CPAS demonstrates significant narrowing of the nasal cavity (not just the pyriform aperture) in infants with CPAS. Significantly smaller nasal width was noted at pyriform aperture, LW-1, and LW-2 (p<0.01, p<0.01, p=0.02). No significant narrowing was seen at the choana.
These findings suggest that CPAS is associated with narrowing of the anterior 75% of the nasal cavity. This has implications for surgical management because simple pyriform aperture ostectomy may not be sufficient to relieve symptoms of obstruction.
确定先天性梨状孔狭窄（CPAS）婴儿鼻腔的尺寸。
识别出7例CPAS患儿的鼻腔，并与13例因其他指征接受CT扫描的新生儿（<30日龄）的鼻腔进行比较。
在梨状孔、后鼻孔以及梨状孔与后鼻孔之间沿鼻侧壁的两个标准化点（LW-1和LW-2）测量鼻腔宽度。
CPAS患儿与非CPAS患儿的比较表明，CPAS婴儿的鼻腔（不仅是梨状孔）明显变窄。在梨状孔、LW-1和LW-2处观察到鼻腔宽度显著更小（p<0.01，p<0.01，p=0.02）。后鼻孔未见明显变窄。
这些发现表明CPAS与鼻腔前75%变窄有关。这对手术治疗有影响，因为单纯的梨状孔造口术可能不足以缓解梗阻症状。
