코성형술에 있어서 두개골계측영상의 유용성

Background and Objectives: The photographic documentation of the rhinoplasty is important for analysis but it often yields different length depending on the angle or inclination of the object. The aim of this study is to compare the accuracy of the lateral cephalometric analysis for measuring of a nasal tip projection and rotation. Subjects and Method: Retrospectively, nasal tip projection and nasal tip rotation were measured by real-measurement and lateral cephalometry. Totally, 24 patients who were scheduled for rhinoplasty from March 2015 through February 2016 were enrolled. The difference of the nasal tip projection and rotation by real-measurement and lateral cephalometry was analyzed using the paired t-test. Results: The average of nasal tip projection was 25.1 ± 2.22 mm in the lateral cephalometry group and was 25.1 ± 1.94 mm in the real-measurement group. The difference of nasal tip projection was not significantly different between the lateral cephalometry and real measurement group (p=0.925). Nasal tip rotation was significantly lower in the cephalometry group (85.9° ± 10.7°) than in the real measurement group (90.8°± 10.2°) (p<0.001). Conclusions: Lateral cephalometric analysis may suggest reliable nasal tip projection in rhinoplasty. (J Clinical Otolaryngol 2016;27:275–280)
