Abstract

Abstract:

BACKGROUND: Orthodontic treatment can improve facial aesthetics by changing the position of nose and chin. Therefore, fully-understanding of the nasal morphology and craniomaxillofacial structure is critical for the design of orthodontic treatment, so as to avoid the postoperative facial incongruity.
OBJECTIVE: To study the correlation of nose morphology index with sex, sagittal skeletal features and vertical skeletal features and its differences in adults of Luzhou, and to explore the relationship between nasal parameters and craniofacial parameters, thereby providing references for the diagnosis and design of orthodontics.
METHODS: Totally 240 adult patients in the Department of Orthodontics, Hospital of Stomatology, Southwest Medical University between 2014 and 2016 were enrolled, and X-ray examination of the oral and maxillofacial region was performed to measure the 27 related indexes.
RESULTS AND CONCLUSION: The results of the three-factor ANOVA showed that sex-related significant factors in certain nasal parameters included nasal length, nasal tip height, alarheight, hump, soft-tissue facial convexity, columella convexity, and nasal bone length (P < 0.05). The sagittal skeletal features significantly influenced four nasal parameters including hump, nasolabialangle, nasomentalangle, soft-tissue facial convexity (P < 0.05). The vertical skeletal features were found to be significant for nasal-bone length, soft-tissue facial convexity (P < 0.05). Sex was found to be a significant correlation in nasal morphology and nasal size and nasal protrusion of the male were larger than those of the female. Sagittal skeletal classification had obvious influence on certain nasal parameters, but there were no significant differences in the nasal size among skeletal patterns. Vertical skeletal classification had obvious influence on certain nasal parameters. To conclude, nasal length, prominence, and form are associated with height, length and anteroposterior/vertical position of the maxilla and mandible.

2.1 参与者数量分析纳入患者240例，按意向性处理分析，全部进入结果分析。 2.2 患者基线分析见表1。 2.3 样本重复性检验从240张X射线头颅侧位片中随机抽取30张，由研究者本人于2周后再次进行定点测量，2次测量结果进行配对t 检验，检验结果显示2次测量结果无明显差异，样本重复性好。 2.4 样本正态性检验及方差齐性检验对所有测量项目所得数据进行正态性检验及方差齐性检验，结果显示各测量数据服从正态分布，且方差齐。 2.5 鼻部形态测量指标的三因素分析结果见表2。 2.6 与不同性别有关的鼻部形态指标的差异性比较对与性别有关的的7项鼻形态指标进行t 检验分析，结果显示男性成年人的鼻背长、鼻尖深度、鼻翼深度、鼻峰高度、鼻小柱高度、鼻骨长、软组织面突角等7项指标均大于女性成年人。见表3。 2.7 与不同矢状骨面型有关的鼻部形态指标的差异性比较对与矢状骨面型有关的鼻形态指标在不同矢状骨面型中的差异进行比较分析，显示鼻唇角在Ⅱ类骨面型中大于Ⅰ类与Ⅲ类骨面型，Ⅰ类与Ⅲ类骨面型之间未见明显差异，鼻颏角在Ⅱ类、Ⅰ类、Ⅲ类骨面型中依次增大，软组织面突角在Ⅱ类、Ⅰ类、Ⅲ类骨面型中依次减小，而鼻峰高度在Ⅰ类、Ⅱ类、Ⅲ类骨面型中未见明显差异。见表4。 2.8 与不同垂直骨面型有关的鼻部形态指标的差异性比较对软组织面突角、鼻骨长等鼻形态指标在不同垂直骨面型中的变化趋势进行比较分析，结果显示：软组织面突角表现为高角组>低角组，但低角组与均角组、均角组与高角组之间未见明显差异，鼻骨长则随着低角、均角、高角的变化而依次增大。见表5。 2.9 鼻形态指标与颅颌面形态指标的相关性分析对鼻形态指标与颅颌面形态指标进行Person相关性分析，显示鼻形态指标与颅面形态指标间大部分存在低到中度的相关性：鼻背长与SNA角、Nperp-A呈低度负相关，与上颌长、下颌长、上颌后面高、后面高、上面高、全面高等指标呈中度正相关。鼻尖深度与上颌长、下颌长、上颌后面高、后面高等呈低度正相关，与上面高、全面高呈中度正相关。鼻颏角与SNA角、Nperp-A、上颌长、颌凸角呈低度负相关，与Nperp-Pg、ANB角呈中度负相关，与下颌长、SNB角、面角呈正相关，相关系数从低度到中度。软组织面突角与Nperp-A、Nperp-Pg、ANB角、颌凸角呈中度到高度正相关，与SNB角、面角、下颌长呈中度负相关变化。鼻骨长与SNA角、Nperp-A呈低度负相关变化，与下颌长、上颌后面高、后面高、全面高、腭平面角、下颌平面角呈低度正相关，与上面高呈中度正相关变化。见表6。 "
