Despite numerous papers relating to the prediction of nose projection for the purposes of facial approximation, there is little guidance for nose tip shape that has been evaluated on a known data set. This study presents a novel, simple technique for validation of the reconstructed nose tip shape based on methods used in actual approximation practice. The data set was comprised of 25 full-head computed tomography (CT) patient scans. In 22 of the 25 patients across all age and sex groups, when the head is tilted so that soft tissue pronasale is superimposed on hard tissue rhinion, the curvature of the nose tip was found to mimic the curvature of the superior portion of the nasal aperture. This occurs when the head is tilted dorsally by approximately 60° (55.87±5.91). Individuals with snub noses presented a much wider tip curvature. The method was highly repeatable and was evaluated through inter- and intra-observer studies (error=3.15%).
尽管有许多关于预测鼻子突出度以进行面部模拟的论文，但对于鼻尖形状的指导却很少，而且这些指导也没有在已知的数据集上进行评估。本研究提出了一种新颖、简单的技术，用于基于实际近似实践中使用的方法验证重建鼻尖形状。该数据集由 25 名全头颅计算机断层扫描 (CT) 患者扫描组成。在 25 名患者中的 22 名患者中，当头部倾斜以使软组织 pronasale 与硬组织 rhinion 重叠时，发现鼻尖的曲率类似于鼻口上部的曲率。当头部向后倾斜约 60°（55.87±5.91）时，会发生这种情况。塌鼻患者的鼻尖曲率较宽。该方法具有高度的可重复性，并通过观察者间和观察者内研究进行了评估（误差=3.15%）。
