目的：确定鼻窝大小的正常值，以更好地描述有鼻塞而无后鼻孔闭锁的婴幼儿鼻狭窄的概念。设计：病例系列。设置：转诊中心。患者：62名婴儿的对比样本（年龄0至6个月），没有颅面畸形，接受了常规轴向计算机断层扫描检查神经系统疾病。干预：从计算机存储的图像中，检查了在鼻窝底水平和上方水平拍摄的切片。长度和10个测量的宽度的鼻窝被用来确定正常values.Results：大多数测量，甚至长度的鼻窝，正相关的患者的年龄（R = 0.44）。在0至2个月组中，中位长度为29.35 mm（范围：21.3-40.4 mm）。4 - 6个月组为31.5 mm（范围：25.3-36.9 mm）。前骨性开口是评估新生儿鼻窝狭窄最准确的距离。其中位宽度为13.5 mm（范围：8.8-17.2 mm）。大的变化特点的尺寸中鼻窝和choeble：中位数为7.6毫米（范围，4.9-13.5毫米）和14.3毫米（范围，10.8-19.0毫米），分别。结论：本研究定义的正常范围内的变化的主要尺寸的鼻窝在水平面。这些可以作为确定新生儿阻塞性鼻狭窄的基础。
Objective: To determine normal values in the size of nasal fossae to better delineate the concept of nasal stenosis in young infants with nasal obstruction and without choanal atresia.Design: Case series.Setting: Referral center.Patients: Consecutive sample of 62 infants (aged 0 to 6 months) with no craniofacial anomalies who underwent conventional axial computed tomography scans for a neurologic disorder.Intervention: From computer-stored images, the slices taken at the level of the nasal fossae floor and those just above were examined. The length and 10 measurements of the width of the nasal fossae were used to determine normal values.Results: Most measurements, even the length of the nasal fossae, were positively correlated to the age of the patient (R =.44). In the age 0 to 2 months group, the median length was 29.35 mm (range, 21.3-40.4 mm). It was 31.5 mm in the age 4 to 6 months group (range, 25.3-36.9 mm). The anterior bony aperture seems to be the most accurate distance for the assessment of neonatal nasal fossae stenosis. Its median width was 13.5 mm (range, 8.8-17.2 mm). Large variations characterized the dimensions of the middle nasal fossae and the choanae: median values were 7.6 mm (range, 4.9-13.5 mm) and 14.3 mm (range, 10.8-19.0 mm), respectively.Conclusions: This study defined the normal range of variation for the main dimensions of the nasal fossae in the horizontal plane. These can be used as a basis for determining nasal stenosis in cases of neonatal obstruction.
