Facial symmetry is prized for its association with health, genetic quality, and attractiveness, but minor asymmetries are common. Human asymmetry tends to favor the left side and is noticeable in various nose parts. However, the discrepancy in cartilage thickness between the nose's right and left sides remains understudied.
This cross-sectional study involved 60 patients undergoing primary open rhinoplasty. During routine rhinoplasty Procedure, upper and lower lateral cartilage strips were excised from each patient, yielding four tissue samples. Tissue thickness and width were measured using a microscope stage calibration slide. This approach systematically assessed left and right cartilage thickness differences in primary open rhinoplasty patients, offering insights into nasal asymmetry and potential surgical implications.
Out of 60 patients, 43 were female (72%) and 17 were male (28%). The mean thickness of upper lateral (UL) cartilage was 0.53 mm on the right and 0.54 mm on the left side (P value= 0.52). For lower lateral (LL) cartilage, the mean thickness was 0.50 mm on the right and 0.54 mm on the left side (P value < 0.001), indicating significant left-sided dominance. This dominance was consistent across both sexes.
Our study highlights the significance of addressing subtle nasal cartilage asymmetries to improve postoperative symmetry. Modifying nasal cartilage microstructures during rhinoplasty can enhance both aesthetic and functional outcomes.

面部对称因其与健康、遗传质量和吸引力相关而备受推崇，但轻微的不对称很常见。人类的不对称往往更倾向于左侧，并且在鼻子的各个部位都很明显。然而，鼻子左右两侧软骨厚度的差异仍未得到充分研究。
这项横断面研究纳入了60例接受初次开放式鼻整形手术的患者。在常规鼻整形手术过程中，从每位患者身上切除上外侧软骨条和下外侧软骨条，共获得四个组织样本。使用显微镜载物台校准载玻片测量组织的厚度和宽度。这种方法系统地评估了初次开放式鼻整形手术患者左右软骨厚度的差异，为鼻不对称及潜在的手术影响提供了见解。
60例患者中，43例为女性（72%），17例为男性（28%）。上外侧（UL）软骨的平均厚度右侧为0.53毫米，左侧为0.54毫米（P值 = 0.52）。下外侧（LL）软骨的平均厚度右侧为0.50毫米，左侧为0.54毫米（P值 < 0.001），表明左侧明显占优势。这种优势在男女两性中均一致。
我们的研究强调了处理细微的鼻软骨不对称以改善术后对称性的重要性。在鼻整形手术中改变鼻软骨微观结构可以提高美学和功能效果。
