Nasal tip correction is one of the most challenging parts of rhinoplasty. The objective of the study was to compare the prevalence of supra-alar crease deepening in lateral crura steal (LCS) and lateral crura overlay (LCO) techniques.
In this prospective study, eligible patients referred to a university hospital for septorhinoplasty during 2022 were included.
The study was conducted on 200 patients in two groups (100 patients in each group), 162 were women and 38 men with a mean age of 31.12 ± 0.60 years. In the third month of follow-up, 36.5% of all studied patients had supra-alar crease deepening, of whom 13% were in the interrupt group and 23.5% were in the steal group (P = 0.002); however, only 4% in the LCO and 9% in the LCS group had aesthetic or breathing disorders (P = 0.25). Deepening of the alar crease was not significantly related to the skin thickness in the two techniques.
According to the results, both LCO and LCS techniques are effective in achieving successful outcomes, although the problematic supra-alar crease deepening is less common in the LCO group; therefore, it seems to be a more suitable option in cases where there is a greater need to tip rotation, although this finding was not statistically significant.

鼻尖矫正术是鼻整形术中最具挑战性的部分之一。本研究的目的是比较外侧脚窃取（LCS）和外侧脚覆盖（LCO）技术中鼻翼上皱襞加深的发生率。
在这项前瞻性研究中，纳入了2022年期间转诊至大学医院接受鼻中隔鼻整形术的符合条件的患者。
该研究对两组共200例患者进行（每组100例），其中女性162例，男性38例，平均年龄为31.12±0.60岁。在随访的第三个月，所有研究患者中有36.5%出现鼻翼上皱襞加深，其中中断组为13%，窃取组为23.5%（P = 0.002）；然而，LCO组仅有4%，LCS组有9%出现美学或呼吸障碍（P = 0.25）。两种技术中鼻翼皱襞加深与皮肤厚度均无显著相关性。
根据结果，LCO和LCS技术在取得成功结果方面均有效，尽管鼻翼上皱襞加深问题在LCO组中较少见；因此，在更需要鼻尖旋转的情况下，它似乎是一个更合适的选择，尽管这一发现无统计学意义。
