【摘要】：研究發(fā)現(xiàn),患有遺傳性疾病的人臉常伴有面部發(fā)育異常的問(wèn)題,如患有威廉姆斯綜合征(WS)和唐氏綜合征(DS)的人臉。為此,對(duì)兒童面部發(fā)育的研究有助于遺傳性疾病的早篩查與早診斷�；谀壳皣�(guó)內(nèi)還沒(méi)有兒童3D人臉數(shù)據(jù)庫(kù)的現(xiàn)狀,通過(guò)3dMDface人臉采集系統(tǒng),采集人臉5 600例,對(duì)原始數(shù)據(jù)進(jìn)行預(yù)處理使人臉稠密對(duì)應(yīng),從而構(gòu)建3D人臉數(shù)據(jù)庫(kù)。利用人體測(cè)量學(xué)標(biāo)定面部各器官的關(guān)鍵點(diǎn),建立標(biāo)準(zhǔn)測(cè)量指標(biāo),建立兒童面部發(fā)育評(píng)估系統(tǒng)。其中,對(duì)浙江地區(qū)分別患有DS的人臉55例和患有WS的人臉30例的19項(xiàng)測(cè)量指標(biāo)與正常人臉比較分析。結(jié)果發(fā)現(xiàn),DS人臉兩眼內(nèi)寬分布在第90百分位以上的樣本為76.3%,鼻長(zhǎng)分布在第10百分位以下的樣本為61.8%,耳長(zhǎng)分布在第10百分位以下的樣本為87.2%,上面深分布在第10百分位以下的樣本為89%,顱面變異指數(shù)為1.630~2.117,T檢驗(yàn)分析為T=10.130,P=.000;WS人臉鼻寬與口裂寬分布在第75百分位以上的樣本分別為50%和66.7%,而兩耳屏間寬分布在第25百分位以下的樣本為63.3%,顱面變異指數(shù)為1.714~2.365,T檢驗(yàn)分析為T=12.213,P=.000。這表明,該兩種特殊人臉與正常人臉差異具有明顯的統(tǒng)計(jì)學(xué)意義。因此,利用該評(píng)估系統(tǒng)能正確反映患有遺傳性疾病特殊人臉的顯著性特征,基于3D人臉數(shù)據(jù)庫(kù)建立的面部發(fā)育評(píng)估系統(tǒng)對(duì)兒童生長(zhǎng)發(fā)育及面部異常的評(píng)價(jià)具有臨床應(yīng)用價(jià)值。
[Abstract]:Studies have found that faces with inherited diseases are often associated with facial dysplasia, such as those with Williams' syndrome (WS) and Down's syndrome (DSV). The research on facial development of children is helpful to the early screening and diagnosis of genetic diseases. Based on the fact that there is no 3D face database for children in China, 3D MDface face acquisition system is adopted. In order to construct 3D face database, 5 600 face samples were collected and processed to make the human face dense. The key points of facial organs were calibrated by anthropometry, and the standard measurement indexes were established. To establish the evaluation system of children's facial development. The 19 indexes of 55 face cases with DS and 30 cases with WS face in Zhejiang area were compared with the normal faces. The results showed that: 1. 76.3% of the eyes of DS face were above the 90th percentile, and 61.8% of the nose length were below the 10th percentile. The ear length distribution below 10th percentile was 87.2 and the upper depth below 10th percentile was 89. The craniofacial variation index was 1.630 and 2.117. The analysis of T test was: TX 10.130 Pu. 000; The samples of WS with nose width and mouth fissure width above 75th percentile were 50% and 66.7, respectively, while 63.3% samples with width between the two ears under 25th percentile. The craniofacial variation index was 1.714 and 2.365 T test. The difference between these two special faces and normal faces is statistically significant. Therefore, the evaluation system can accurately reflect the salient features of special faces with hereditary diseases. The evaluation system of facial development based on 3D face database is of clinical value for the evaluation of children's growth and development and facial abnormalities.
