Previously described methods for quantifying nasal tip projection were evaluated. Fifty-one nasal profiles were analyzed and scored by expert rhinoplastic surgeons. The noses and faces were then evaluated quantitatively using several methods. The methods were found to vary widely in their correlation with the experts' subjective analyses. Several helpful relationships and guides were obtained: 1. Aesthetic tip projection does not correlate well with upper lip length. 2. A new method described in this paper showed the best correlation with the experts' opinions (regression, r value = 0.8132). This method related tip projection to total nasal length (including upper lip length). 3. The second new method tested in this report yielded helpful data by comparing tip projection with overall facial length. 4. After slight modification the method previously described by Goode proved useful as nasal length and desired tip projection formed a 3:4:5 right triangle.
对先前描述的鼻尖突出度量化方法进行了评估。51例鼻外形由鼻整形专家进行分析和评分。然后使用几种方法对鼻子和面部进行定量评估。结果发现，这些方法与专家主观分析的相关性差异很大。获得了几个有用的关系和指导原则：1. 美学鼻尖突出度与上唇长度的相关性不佳。2. 本文描述的一种新方法与专家意见的相关性最佳（回归分析，r值 = 0.8132）。该方法将鼻尖突出度与鼻总长度（包括上唇长度）相关联。3. 本报告中测试的第二种新方法通过比较鼻尖突出度与面部总长度得出了有用的数据。4. 经过轻微修改后，古德先前描述的方法证明是有用的，因为鼻长度与期望的鼻尖突出度形成了一个3:4:5的直角三角形。
