This study aimed to elucidate the relationship between nasal septal deviation (NSD) and upper lateral cartilage (ULC) collapse.
We conducted a retrospective review of 142 paranasal sinus computed tomography scans from patients who had undergone septoplasty due to confirmed NSD. The ULC angle was measured on both the narrow and wide sides of the nasal cavities, and these measurements were compared to evaluate the extent of ULC collapse in relation to the degree of NSD and patient age. The correlation between the degree of NSD and the degree of ULC collapse was also analyzed.
The mean ULC angle was found to be 13.4°±2.7° on the narrow side and 14.3°±2.7° on the wide side, with a statistically significant difference between the two (p<0.001). When comparing caudal and non-caudal NSD patients, there was no significant difference in the degree of ULC on either side (p=0.166). When comparing the ULC angle between two age groups (≥50 vs. <50 years), the difference in ULC angles was significantly greater in the group of patients aged under 50 years (0.3°±3.8° vs. 1.1°±2.2°, p=0.014). There was a significant positive correlation between the degree of ULC collapse and the degree of septal deviation (r=0.214, p=0.01).
NSD was associated with ULC collapse on the narrow side and a narrow internal nasal valve area. This result indicates that clinicians should check for concomitant ULC collapse in patients with NSD.
本研究旨在阐明鼻中隔偏曲（NSD）与上外侧软骨（ULC）塌陷之间的关系。
我们对142例因确诊NSD而接受鼻中隔成形术患者的鼻窦计算机断层扫描进行了回顾性分析。在鼻腔的狭窄侧和宽阔侧测量ULC角，并比较这些测量值，以评估ULC塌陷程度与NSD程度和患者年龄的关系。还分析了NSD程度与ULC塌陷程度之间的相关性。
发现狭窄侧的平均ULC角为13.4°±2.7°，宽阔侧为14.3°±2.7°，两者之间存在统计学显著差异（p<0.001）。比较尾侧和非尾侧NSD患者时，两侧的ULC程度无显著差异（p=0.166）。比较两个年龄组（≥50岁与<50岁）之间的ULC角时，50岁以下患者组的ULC角差异明显更大（0.3°±3.8°对1.1°±2.2°，p=0.014）。ULC塌陷程度与鼻中隔偏曲程度之间存在显著正相关（r=0.214，p=0.01）。
NSD与狭窄侧的ULC塌陷和狭窄的鼻内瓣膜区域相关。这一结果表明临床医生应检查NSD患者是否伴有ULC塌陷。
