| 鼻腔底部宽度与鼻腔外侧缘宽度的测量 3A, line between anterior nasal spine (ANS) and posterior nasal spine (PNS) was divided into three equal parts, and nasal lateral width (NLW)/nasal floor width (NFW) was measured at the midpoint of each part; 3B, NLW/NFW was measured. OPS, oropharyngeal sagittal; OPT, oropharyngeal transverse. |
