Nasal dynamics were studied on 87 patients undergoing rhinoplasty of one zone or two distant nasal zones. Statistical analysis of the result revealed that reduction of the nasion area, besides setting the soft tissue back, gave the appearance of increased intercanthal distance and lengthened the nose. Reduction of the nasal bridge resulted in a wider appearance on front view and a cephalically rotated tip on profile. Augmentation of the bridge affected the nose reversely. Tip cephalad rotation was achieved by resecting one of the three areas: the cephalad portion of the lower lateral cartilages (affecting the rims more), the caudal septum (affecting the central portion more), and the caudal portion of the medial crura of the lower lateral cartilages (affecting the central portion only). Resection of the alar base not only narrowed the nostrils but also moved the alar rim caudally. Furthermore, it reduced tip projection when a large alar base reduction was done. Reduction of the nasal spine increased the upper lip length on profile and reduced tip projection when a large reduction took place. Significant reduction in caudal nose projection resulted in widening of the alar base.
对87例行单区域或两个远隔鼻区域鼻整形术的患者的鼻腔动力学进行了研究。结果的统计分析显示，鼻根区域的缩小，除了使软组织后移外，还会使内眦间距增大，鼻子显得变长。鼻梁的缩小导致正面观变宽，侧面观鼻尖向上旋转。鼻梁增高对鼻子的影响则相反。通过切除以下三个区域之一可实现鼻尖向上旋转：下外侧软骨的头侧部分（对鼻翼缘影响更大）、鼻中隔尾侧部分（对中央部分影响更大）以及下外侧软骨内侧脚的尾侧部分（仅对中央部分有影响）。鼻翼基底切除术不仅使鼻孔变窄，还使鼻翼缘向尾侧移动。此外，当大量切除鼻翼基底时，还会降低鼻尖突出度。鼻棘的缩小会增加侧面观的上唇长度，当大量缩小鼻棘时会降低鼻尖突出度。鼻尾侧突出度的显著降低会导致鼻翼基底变宽。
