【摘要】：目的：对替牙期单侧完全性唇腭裂(Unilateral complete cleft lip and palate, UCLP)患者与非唇腭裂患者的头颅定位正位片、全颌曲面断层片进行对比分析,研究替牙期UCLP患者颌面部垂直向与横向的对称性,并进一步探讨UCLP患者上下颌骨发育不对称间的相关性。方法：选择30例替牙期UCLP患者(男16例,女14例)作为UCLP组,30例替牙期非唇腭裂患者(男15例,女15例)作为对照组。应用人工描绘定点,通过头颅定位正位片与全颌曲面断层片对两组患者的颌面部硬组织相关测量项目进行比较,分析UCLP患者颌面部垂直向与横向的对称性。所有数据使用SPSS19.0统计软件进行统计分析。结果： 1.垂直向对称性： ①垂直向,替牙期UCLP患者两侧MxH、NcH、NaH、CoH、GoH、AgH、CH。RH、 CH+RH、d-Ag均存在不对称,差异具有统计学意义(P0.05)；其中非裂隙侧的CoH、GoH、 AgH、CH、RH、CH+RH大于裂隙侧。 ②替牙期UCLP患者颌面部垂直向非对称率较大的部位在Na点(8.76%)、Nc点(7.8%)。 ③与对照组相比,替牙期UCLP患者在Mx、Nc、Na、Co、Go、Ag、CH、RH、CH+RH、 d-Ag上的垂直向非对称率有差异且有统计学意义(P0.05)。 ④在垂直向,UCLP患者Go的非对称率与Nc的非对称率,存在一定程度地相关性(P0.05)。 2.横向对称性： ①横向,替牙期UCLP患者两侧MxV、NcV、NaV、CoV、GoV、AgV均存在不对称,且差异具有统计学意义(P0.05),且非裂隙侧上下颌骨的横向宽度大于裂隙侧。 ②替牙期UCLP患者颌面部横向非对称率较大的部位在Na点(29.19%)、Nc点(21.99%)。 ③横向,替牙期UCLP患者Ag的非对称率与Nc的非对称率存在相关性,且有统计学意义(P0.05)。结论： ①替牙期UCLP患者颌面部存在垂直向与横向的不对称畸形。 ②替牙期UCLP患者的上颌骨不对称畸形比下颌骨严重,其中以梨状孔区最为显著。 ③在垂直向与横向,替牙期UCLP患者裂隙侧下颌骨较健侧发育不足；在横向,替牙期UCLP患者裂隙侧上颌骨较健侧发育不足。 ④替牙期UCLP患者上下颌骨的非对称率有一定的相关性。
[Abstract]:Objective: to study the vertical and transverse symmetry of maxillofacial region in patients with unilateral complete cleft lip and palate (UCLP) and non-cleft cleft lip and palate (UCLP) patients with unilateral unilateral cleft lip and palate (UCLP) and non-cleft lip and palate (non-cleft lip and palate) patients with unilateral unilateral cleft lip and palate. And to further explore the relationship between the development asymmetry of the upper and lower jaw in UCLP patients. Methods: 30 UCLP patients (16 males and 14 females) were selected as control group in UCLP group, 30 patients with cleft lip and palate (15 males and 15 females) were selected as control group. The vertical and lateral symmetry of maxillofacial hard tissue in patients with UCLP were analyzed by comparing the items of maxillofacial hard tissue measurement in two groups by cephalometric orthograph and total maxillary surface tomograph. All the data were statistically analyzed by SPSS19.0 statistical software. Results:. 1. Vertical symmetry:. 1 in the vertical direction, there was asymmetry in both sides of UCLP patients with UCLP. The difference was statistically significant (P0.05A), and the RHCH in the non-fractured side was larger than that in the fissured side (P < 0.05), and the RHCH RH in the unfractured side was higher than that in the fissure side (P < 0.05). The results were as follows: (1) there was no symmetry in both sides of the patients with UCLP in the orthodontic phase, and the difference was statistically significant (P0.05A). (2) the higher vertical asymmetry of maxillofacial region in UCLP patients during dental replacement stage was found at Na point 8.76% and NC point 7.8%. 3Compared with the control group, there was a significant difference in the vertical asymmetry rate of the UCLP patients in the Mxncncncncncna CoCoA, CHH, d-Ag in the RHH, d-Ag, and there was significant difference in the vertical asymmetry rate between the patients and the control group (P 0.05). (4) there was a certain correlation between the asymmetric rate of go and the asymmetric rate of NC in the patients with UCLP. 2. Horizontal symmetry:. 1in transverse, both sides of UCLP patients with UCLP had asymmetry in both sides, and the difference was statistically significant (P 0.05), and the transverse width of the upper and lower bones in the non-fissured side was larger than that in the fissured side. 2the greater transverse asymmetry rate of maxillofacial region in patients with UCLP in dental replacement stage was found at Na point 29.19 and NC point 21.99%. 3Transverse, the asymmetrical rate of Ag was correlated with the asymmetrical rate of NC in patients with UCLP in dental replacement stage, and there was statistical significance (P 0.05). Conclusion:. 1 there were vertical and transverse asymmetry in maxillofacial region in patients with UCLP at dental replacement stage. 2the asymmetry of maxilla in UCLP patients was more serious than that in mandible, especially in piriform foramen. (3) in vertical and lateral directions, the mandible of fissure side of UCLP patients was less developed than that of healthy side, and the maxillary bone of fissured side of patients with UCLP was underdeveloped in transverse direction. 4 there was a certain correlation between the asymmetry rate of upper and mandibular bone in UCLP patients.
