Congenital neonatal pyriform aperture stenosis (CNPAS) is a rare but potentially lethal condition that causes respiratory distress. The characteristic narrowing of the pyriform aperture along with other associated craniofacial dysmorphism is diagnosed using cross-sectional imaging such as computed tomography (CT) and magnetic resonance imaging. CT scan is the imaging of choice for confirming and characterizing CNPAS. Infants are obligate nasal breathers in the first 5 months of life. Hence, a high degree of clinical suspicion, prompt imaging diagnosis and adequate respiratory support is critical to help reduce the morbidity of this condition.
先天性新生儿梨状孔狭窄（CNPAS）是一种罕见但可能致命的疾病，可导致呼吸窘迫。梨状孔的特征性狭窄以及其他相关的颅面畸形可通过计算机断层扫描（CT）和磁共振成像等横断面成像进行诊断。CT扫描是确诊和表征CNPAS的首选成像方法。婴儿在出生后的前5个月是完全通过鼻腔呼吸的。因此，高度的临床怀疑、及时的影像诊断和充分的呼吸支持对于降低这种疾病的发病率至关重要。
