Abstract

BACKGROUND

Cephalic malposition of the lower lateral cartilages is a common nasal anatomic variation. Knowing the range of lateral crura (LC) divergence angle in Iranian population can help Middle East plastic surgeons. This study aimed to determine LC divergence angle of candidates for primary rhinoplasty in Iranian population.

METHODS

This cross-sectional study was conducted on 256 candidates for primary rhinoplasty from November 2017 through May 2018. Two sides of LC divergence angle were measured intraoperatively by a researcher-made device.

RESULTS

Totally, 211 female and 45 male patients with the mean age of 29.9±6.51 years were recruited. The mean LC divergence angle was 35.86±4.74° (between 20-50°). The mean LC divergence angle was 35.11° and 36.02° in male and females, respectively. There was no significant difference between males and females. In addition, there was no significant correlation between LC divergence angle and age. LC divergence angle had normal distribution and about 68% of the LC divergence angle were within one standard deviation of the mean (i.e. 32 to 40 degree).

CONCLUSION

In 16% of studied people, the divergence angle of the lateral crus of the lower lateral cartilage was lower than 32° and was considered as malposition.

摘要

背景

下外侧软骨的头部位置异常是一种常见的鼻部解剖变异。了解伊朗人群中外侧脚（LC）发散角的范围有助于中东地区的整形外科医生。本研究旨在确定伊朗人群中原发性鼻整形术候选人的LC发散角。

方法

本横断面研究于2017年11月至2018年5月对256例原发性鼻整形术候选人进行。由研究人员自制的设备在术中测量LC发散角的两侧。

结果

共招募了211名女性和45名男性患者，平均年龄为29.9±6.51岁。平均LC发散角为35.86±4.74°（20 - 50°之间）。男性和女性的平均LC发散角分别为35.11°和36.02°。男性和女性之间无显著差异。此外，LC发散角与年龄之间无显著相关性。LC发散角呈正态分布，约68%的LC发散角在平均值的一个标准差范围内（即32至40度）。

结论

在16%的研究对象中，下外侧软骨外侧脚的发散角低于32°，被认为是位置异常。
