Abstract

Objective

Nasal septal surgery is an effective procedure for nasal obstruction; however, caudal deviation (CD) must be managed carefully. The diagnosis of CD is often subjective, and an objective index test method is required. Accordingly, we established reference values for the nasal area ratio in the horizontal section (NAR-H) and nasal area ratio in the coronal section (NAR-C) on computed tomography in CD.

Methods

This retrospective observational study included 120 patients who underwent septoplasty for nasal obstruction. Patients who underwent caudal septoplasty were categorised into the CD group, while those who underwent classical septoplasty were categorised into the septal deviation (SD) group. The mean NAR-H and NAR-C values of both groups were compared. Moreover, the cutoff NAR-H and NAR-C values in the CD group were calculated, and the sensitivity and specificity of each were calculated.

Results

CD and SD groups included 49 and 71 patients, respectively. The mean NAR-H was 0.43 and 0.75 in the CD and SD groups, respectively (p < 0.0001). The mean NAR-C was 0.56 and 0.80 in the CD and SD groups, respectively (p < 0.0001). The cutoff NAR-H and NAR-C values in the CD group were 0.56 and 0.675, respectively. The area under the ROC curve of the NAR-H and NAR-C were 0.90 and 0.88, respectively.

Conclusions

The NAR-H and NAR-C may be useful for diagnosing CD. An NAR-H of <0.56 and NAR-C of <0.675 indicates the need to prepare for a caudal septoplasty.

计算机断层扫描测量的左右鼻腔面积比能否作为尾间隔偏曲的客观诊断标准？

目的：鼻中隔手术是治疗鼻塞的有效方法；然而，尾侧偏（CD）必须谨慎处理。乳糜泻的诊断往往是主观的，需要客观的指标测试方法。因此，我们建立了cd计算机断层水平面鼻面积比（NAR-H）和冠状面鼻面积比（NAR-C）的参考值。方法：本回顾性观察研究纳入120例鼻中隔成形术治疗鼻塞的患者。接受尾侧鼻中隔成形术的患者被归类为CD组，而接受经典鼻中隔成形术的患者被归类为间隔偏曲（SD）组。比较两组患者的平均NAR-H、NAR-C值。计算CD组的临界值NAR-H和NAR-C，并计算各自的敏感性和特异性。结果：CD组49例，SD组71例。CD组和SD组的平均NAR-H分别为0.43和0.75 （p < 0.0001）。CD组和SD组的平均NAR-C分别为0.56和0.80 （p < 0.0001）。CD组NAR-H和NAR-C的临界值分别为0.56和0.675。NAR-H和NAR-C的ROC曲线下面积分别为0.90和0.88。结论：NAR-H和NAR-C可用于诊断CD

期刊介绍： The international journal Auris Nasus Larynx provides the opportunity for rapid, carefully reviewed publications concerning the fundamental and clinical aspects of otorhinolaryngology and related fields. This includes otology, neurotology, bronchoesophagology, laryngology, rhinology, allergology, head and neck medicine and oncologic surgery, maxillofacial and plastic surgery, audiology, speech science. Original papers, short communications and original case reports can be submitted. Reviews on recent developments are invited regularly and Letters to the Editor commenting on papers or any aspect of Auris Nasus Larynx are welcomed. Founded in 1973 and previously published by the Society for Promotion of International Otorhinolaryngology, the journal is now the official English-language journal of the Oto-Rhino-Laryngological Society of Japan, Inc. The aim of its new international Editorial Board is to make Auris Nasus Larynx an international forum for high quality research and clinical sciences.
