Because neonates are obligate nasal breathers, neonatal nasal obstruction may have serious consequences. Prompt diagnosis and appropriate treatment are essential to avoid severe hypoxia. Anterior inlet, piriform aperture stenosis is an extremely rare cause of neonatal nasal airway obstruction and can easily be confused with choanal atresia or stenosis. Computed tomography with direct coronal scans is the best means of establishing a definitive diagnosis. We present our experience with four neonates having nearly complete piriform aperture stenosis. Prompt surgical enlargement of the nasal inlet through an upper buccal sulcus approach is recommended.
由于新生儿是 obligate nasal breathers，新生儿鼻阻塞可能会产生严重后果。及时诊断和适当治疗对于避免严重缺氧至关重要。前鼻孔、梨状孔狭窄是新生儿鼻气道阻塞极为罕见的原因，很容易与后鼻孔闭锁或狭窄相混淆。直接冠状扫描的计算机断层扫描是确立明确诊断的最佳方法。我们介绍了4例患有近乎完全梨状孔狭窄的新生儿的经验。建议通过上颊沟入路迅速对鼻入口进行手术扩大。
