In clinical practice, lateral nasal wall collapse during forced inspiration is widely regarded as a sign of nasal obstruction or criterion indicating nasal valve surgery. This study aims to evaluate the relationship between the degree of lateral nasal wall collapse and subjective nasal obstruction. In addition, factors related to lateral nasal wall collapse were also investigated.
In this study, lateral nasal wall collapse is determined by the degree of lateral nasal wall triangle (LNWT) area reduction on frontal view during forced inspiration compared to quiet inspiration. LNWT area ratio of the patient and control groups was compared. The relationship between the lateral nasal wall collapse and clinical factors including symptom scores, nasal valve angles, skin thickness were evaluated.
The average LNWT area ratio of the patient (n = 24) and control groups (n = 27) was 0.96 and 0.83 respectively ( = .001). Symptom score (NOSE and VAS) is not related to the degree of lateral nasal wall collapse. Moreover, nasal valve angle and skin thickness were also not related to the degree of lateral nasal wall collapse. In 14 of the 19 patients, the more obstructed side corresponded to the side of narrower nasal valve angle, and 5 were not.
Lateral nasal wall collapse is not related to a patients' nasal obstruction.
在临床实践中，用力吸气时发生的鼻中隔侧壁塌陷被广泛认为是鼻塞的征象或提示行鼻阀手术的标准。本研究旨在评估鼻中隔侧壁塌陷的程度与主观鼻塞之间的关系。此外，还研究了与鼻中隔侧壁塌陷相关的因素。
本研究中，通过比较用力吸气与安静吸气时正面观鼻中隔侧壁三角形（LNWT）区域的缩小程度来确定鼻中隔侧壁塌陷程度。比较了患者组和对照组的 LNWT 面积比。评估了鼻中隔侧壁塌陷与包括症状评分、鼻阀角、皮肤厚度在内的临床因素之间的关系。
患者组（n=24）和对照组（n=27）的平均 LNWT 面积比分别为 0.96 和 0.83（ = .001）。症状评分（NOSE 和 VAS）与鼻中隔侧壁塌陷的程度无关。此外，鼻阀角和皮肤厚度也与鼻中隔侧壁塌陷的程度无关。在 19 名患者中的 14 名中，更阻塞的一侧对应于鼻阀角较窄的一侧，而有 5 名则不是。
鼻中隔侧壁塌陷与患者的鼻塞无关。
