Cephalic malposition is an anatomical variant that is found particularly in Middle Eastern people. Malpositioning of the alar cartilage may cause both functional and aesthetic problems. This study aimed to investigate and compare the functional and aesthetic outcomes of the two techniques used to correct cephalic malposition of the lower lateral cartilage: lateral crural overlay (LCO) and lateral crural transposition. This current randomised double-blinded clinical trial was performed on 40 patients who were referred for rhinoplasty in 2017-2018. They were randomly divided into two groups, the lateral crural transposition group (n = 20), and the LCO group (n = 20). The angle between the lateral crura and the midline, nasal rotation, nasal tip projection, nasal axis deviation, columella labial angle, and nasofacial angle, plus a visual analogue scale (VAS) and the 10-item Standardised Cosmesis and Health Nasal Outcomes Survey (SCHNOS), were assessed for each patient before surgery and after 12 months, and further compared between the two groups. Both techniques successfully improved the lateral crural angle, nasal tip rotation, and columella labial angle (p < 0.05). Despite the satisfactory outcomes of the VAS and SCHNOS based on both the patients' and the surgeons' opinions (p < 0.05), comparison of the indices revealed insignificant differences between the two groups (p> 0.05). We obtained successful aesthetic and functional outcomes with both techniques.
头部位置异常是一种解剖学变异，尤其在中东人群中较为常见。鼻翼软骨位置异常可能会导致功能和美观问题。本研究旨在调查和比较用于矫正下外侧软骨头部位置异常的两种技术的功能和美观效果：外侧脚覆盖术（LCO）和外侧脚移位术。这项随机双盲临床试验于2017年至2018年对40例行鼻整形术的患者进行。他们被随机分为两组，外侧脚移位组（n = 20）和LCO组（n = 20）。在手术前和术后12个月，对每位患者评估外侧脚与中线之间的角度、鼻旋转、鼻尖突出度、鼻轴偏差、小柱唇角和鼻面角，以及视觉模拟量表（VAS）和10项标准化美容与健康鼻结果调查（SCHNOS），并在两组之间进一步比较。两种技术均成功改善了外侧脚角度、鼻尖旋转和小柱唇角（p < 0.05）。尽管基于患者和外科医生的意见，VAS和SCHNOS的结果令人满意（p < 0.05），但指标比较显示两组之间差异不显著（p> 0.05）。两种技术均获得了成功的美学和功能效果。
