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.
