This is a diagnostic study that investigates the clinical significance between patients with short and long nasal bones and the variation in upper septal composition that would delineate propensity for middle vault collapse. Computed tomographic scans of 16 female patients undergoing evaluation with sinus films were analyzed. Two measurements were taken from each scout image: nasal bone length and total nasal length. Patient scans were separated into 2 groups; patients whose nasal bone length was less than one-half their total nasal length were defined as patients with "short nasal bone" (n = 8), and those with nasal bones longer than one-half the length of their noses were defined as patients with "long nasal bone" (n = 8). Key differences were identified between patients with short and long nasal bones. Total septal area in the upper vault was decreased in the short nasal bone group relative to that of the long nasal bone group (5.7 ± 0.6 cm vs 8.1 ± 1.0 cm, = .002). This was mainly the result of the decreased ethmoid bone component in the short nasal bone group when compared with the long nasal bone group (1.6 ± 0.6 cm vs 3.2 ± 0.8 cm, = .007).
这是一项诊断性研究，旨在调查鼻骨短和鼻骨长的患者之间的临床意义，以及鼻中隔上部结构的变化，这些变化可描绘中鼻拱塌陷的倾向。对16例接受鼻窦片评估的女性患者的计算机断层扫描进行了分析。从每张定位图像上进行两项测量：鼻骨长度和总鼻长度。患者扫描图像被分为两组；鼻骨长度小于总鼻长度一半的患者被定义为“鼻骨短”患者（n = 8），鼻骨长度大于鼻子长度一半的患者被定义为“鼻骨长”患者（n = 8）。鼻骨短和鼻骨长的患者之间发现了关键差异。与鼻骨长的组相比，鼻骨短的组上鼻拱的总鼻中隔面积减小（5.7±0.6平方厘米对8.1±1.0平方厘米，P = 0.002）。这主要是因为与鼻骨长的组相比，鼻骨短的组筛骨成分减少（1.6±0.6平方厘米对3.2±0.8平方厘米，P = 0.007）。
