The Ottawa Valve Collapse scale (OVCS) was developed to classify the severity of nasal valve collapse (NVC) in patients with nasal obstruction. The goal of this study was to determine, in patients who have nasal obstruction due to a septal deviation, whether those with a higher OVCS grade will have a reduced improvement in patient-centered clinical outcomes at one-year following septoplasty with inferior turbinate diathermy compared to those with a normal or lower OVCS grade. This study was a prospective study of 78 patients who completed an assessment using the NOSE questionnaire before and at one-year following the surgical intervention. A repeated-measures ANOVA was used to asses for differences in scores between OVCS groups. There was a significant improvement in NOSE scores one year post-septoplasty (p < 0.01). There was no difference in NOSE score improvement when comparing the grades of the OVCS at one-year (F = 0.09, p = 0.968). Though the OVCS was designed to categorize the severity of NVC preoperatively, there is no evidence that it is helpful in predicting which patients will demonstrate poor results following septoplasty. Future studies are required to further evaluate the OVCS and whether complimentary assessments will improve its clinical utility.
渥太华鼻阀塌陷分级量表（OVCS）用于对鼻塞患者的鼻阀塌陷（NVC）严重程度进行分类。本研究旨在确定鼻中隔偏曲导致鼻塞的患者中，与 OVCS 分级正常或较低的患者相比，OVCS 分级较高的患者在鼻中隔成形术联合下鼻甲电凝术后一年时，以患者为中心的临床结局改善程度是否降低。本研究是一项前瞻性研究，共纳入 78 例患者，这些患者在手术干预前和术后一年均使用 NOSE 问卷进行了评估。采用重复测量方差分析评估 OVCS 组之间的评分差异。鼻中隔成形术后一年时，NOSE 评分显著改善（p<0.01）。比较 OVCS 分级一年时的 NOSE 评分改善情况，差异无统计学意义（F=0.09，p=0.968）。尽管 OVCS 旨在对 NVC 的术前严重程度进行分类，但尚无证据表明其有助于预测鼻中隔成形术后哪些患者会出现不良结果。需要进一步的研究来评估 OVCS 及其补充评估是否会提高其临床实用性。
