Anthropometric proportions and symmetry are considered determinants of beauty. These parameters have significant importance in facial plastic surgery, particularly in rhinoplasty. As the central organ of the face, the nose is especially important in determining facial symmetry, both through the perception of a crooked nose and through the determination of facial growth. The evaluation of the presence of facial asymmetry has great relevance preoperatively, both for surgical planning and counseling.
AIM/OBJECTIVE: To evaluate and document the presence of facial asymmetry in patients during rhinoplasty planning and to correlate the anthropometric measures with the perception of facial symmetry or asymmetry, assessing whether there is a higher prevalence of facial asymmetry in these patients compared to volunteers without nasal complaints.
This prospective study was performed by comparing photographs of patients with rhinoplasty planning and volunteers (controls), n = 201, and by evaluating of anthropometric measurements taken from a line passing through the center of the face, until tragus, medial canthus, corner side wing margin, and oral commissure of each side, by statistical analysis (Z test and odds ratio).
None of the patients or volunteers had completely symmetric values. Subjectively, 59% of patients were perceived as asymmetric, against 54% of volunteers. Objectively, more than 89% of respondents had asymmetrical measures. Patients had greater RLMTr (MidLine Tragus Ratio) asymmetry than volunteers, which was statistically significant.
DISCUSSION/CONCLUSION: Facial asymmetries are very common in patients seeking rhinoplasty, and special attention should be paid to these aspects both for surgical planning and for counseling of patients.
人体测量比例和对称性被视为美的决定因素。这些参数在面部整形手术中具有重要意义，尤其是在鼻整形术中。作为面部的中心器官，鼻子在决定面部对称性方面尤为重要，这既体现在对歪鼻的感知上，也体现在对面部生长的判定上。术前对面部不对称情况的评估对于手术规划和咨询都具有重要意义。
在鼻整形手术规划过程中评估并记录患者面部不对称的情况，并将人体测量指标与面部对称或不对称的感知进行关联，评估与无鼻部问题的志愿者相比，这些患者中面部不对称的发生率是否更高。
这项前瞻性研究通过比较鼻整形手术规划患者和志愿者（对照组）的照片（n = 201），并通过统计分析（Z检验和比值比）评估从穿过面部中心直至每侧耳屏、内眦、鼻翼缘角和口角的一条线所进行的人体测量数据。
患者和志愿者均无完全对称的值。主观上，59%的患者被认为不对称，而志愿者为54%。客观上，超过89%的受访者测量值不对称。患者的RLMTr（中线耳屏比值）不对称程度高于志愿者，具有统计学意义。
讨论/结论：面部不对称在寻求鼻整形手术的患者中非常常见，在手术规划和患者咨询时都应特别关注这些方面。
