Upper lateral cartilage manipulation is often associated with compromise of the middle-third vault. Although the anatomical details of the upper lateral cartilages are of great importance for the maintenance or even the creation of an aesthetically pleasing dorsum with proper respiratory function, the literature includes few studies related to these themes. Thus, this study aimed to evaluate the total length of the upper lateral cartilages and their extension under the nasal bones and caudally, and examine the anatomical variations of the upper lateral cartilages and their implications in rhinoplasty.
An anatomical study was performed on 32 upper lateral cartilages of 16 fresh adult cadavers. The upper lateral cartilages were measured for total length, cephalad length (overlapped by the nasal bones), and caudal length (caudally to the nasal bones) using a millimeter ruler. The measurements were recorded and analyzed by BioEstat 5.0 software. The statistical tests were performed at the significance level of 0.05.
A total of 13 male specimens and 3 female specimens with ages ranging between 20 and 60 years were analyzed. The length of the upper lateral cartilage portion under the nasal bones on the right side ranged from 3 to 7 mm (4.62 ± 1.20 mm). On the left side, it ranged from 2 to 7 mm (4.56 ± 1.26 mm). The total length of the upper lateral cartilages ranged from 16 to 28 mm (20.44 ± 3.26 mm) on the right side and 17 to 30 mm (20.75 ± 3.71 mm) on the left side.
Data from this study confirmed the anatomical variations of the upper lateral cartilages, including the portion lying under the nasal bones. This has important surgical implications given the attention required during spreader graft fabrication in order to maintain dorsal aesthetic lines and proper respiratory function.
上外侧软骨的操作常导致中三分之一穹窿的受损。尽管上外侧软骨的解剖细节对于维持甚至创造具有适当呼吸功能的美观背侧非常重要，但文献中很少有关于这些主题的研究。因此，本研究旨在评估上外侧软骨的总长度及其在鼻骨下和尾部的延伸，并检查上外侧软骨的解剖变异及其在鼻整形术中的意义。
对 16 具新鲜成人尸体的 32 个上外侧软骨进行解剖学研究。使用毫米尺测量上外侧软骨的总长度、头侧长度（与鼻骨重叠）和尾侧长度（在鼻骨下方）。使用 BioEstat 5.0 软件记录和分析测量结果。统计检验的显著性水平为 0.05。
共分析了 13 名男性和 3 名女性标本，年龄在 20 至 60 岁之间。右侧鼻骨下上外侧软骨部分的长度范围为 3 至 7 毫米（4.62±1.20 毫米）。左侧范围为 2 至 7 毫米（4.56±1.26 毫米）。右侧上外侧软骨的总长度范围为 16 至 28 毫米（20.44±3.26 毫米），左侧为 17 至 30 毫米（20.75±3.71 毫米）。
本研究的数据证实了上外侧软骨的解剖变异，包括位于鼻骨下方的部分。这对于在制作扩宽移植物时需要注意维持背侧美学线和适当的呼吸功能具有重要的手术意义。
