【摘要】 研究目的应用X线头影测量的方法对成年未手术的腭裂患者进行颅颌面部软硬组织的测量分析,通过分析研究成人未手术腭裂的软硬组织特点。研究方法选取2009年9月-2011年9月安徽医科大学附属口腔医院颌面外科收治的60例未手术的成年腭裂患者,无唇裂病史,年龄18-23(20.2±1.8)岁,男34例,女26例。其中不完全性腭裂25例,男13例,女12例；单侧完全性腭裂35例,男22例,女13例；对照组：选取安徽医科大学在校健康学生60例,男30例,女30例,年龄20-25(22.9±2.6)岁。采用X线头影测量方法对实验组和对照组分别进行软硬组织测量,参考Downs及Wylie分析法测量项目,选择28项测量内容,其中硬组织22项,软组织6项。线距测量12项,角度测量14项,得到的两组数据以t检验进行统计学分析。结果研究发现,实验组的SNA(上牙槽座角)、ANB(上下牙槽座角)及N-A-Po(颌凸角)等结果低于对照组,差异有统计学意义(P<0.01)。MP-SN(下颌平面角)与对照组比较偏大,差异有统计学意义(P<0.05),Y轴角值减小(P<0.01)。ANS-Ptm(上颌长)、Co-Po(下颌长)、SL均低于正常组,差异有统计学意义(P<0.01)。G-Sn-Po’(面型角)、G-Prn-Po’(全面凸角)、均增大；ULP(上唇突度)减少,与对照组比较差异有统计学意义(P<0.01)。实验组和对照组之间年龄、性别结构比较均衡,没有统计学差异；不同组的数据具有可比性。同时还发现在成人腭裂患者中,有56例存在严重的咬合错乱现象,占总体的93.3%。结论硬组织方面腭裂患者的上颌骨存在明显的发育不足、硬腭长度过短、下颌颏部前伸现象明显,下颌骨向下旋转及后退。而软组织方面腭裂患者面中1/3凹陷明显,上唇突度不足。更多还原

【Abstract】 ObjectsTo evaluate the effects of cleft palate on the craniofacial morphology in adult patients with unoperated cleft palate by cephalometric analysis,analysis the characteristics of the soft and hard tissues.MethodsSelection60cases the adult patients with unoperated cleft surgery from anhui medical university hospital affiliated oral and maxillofacial surgery in September2009to September2011, no harelip history, age18to23(20.2+/-1.8) years old, male34cases,26were women.The incomplete of cleft25cases, male13cases, female12cases; Unilateral complete cleft35cases, male22cases, female13cases. The control group: select60health students in anhui medical university, male30cases, female30cases, aged20to25(22.9+/-2.6) years old.By using cephalometric analysis measured the hard and soft tissues between experimental group with the control group, reference Downs and Wylie analysis measurement items, selected28measurement items, which a hard tissue22, the soft tissue6items.linespacing measuring12, Angle measurement14items, The data of the cephalometric measurements were compared with the control group by t test.Results Research found that the SNA, ANB and N-A-Po results such as the lower than those of the control group, the difference was statistically significant (P<0.01). MP-SN compared with controls group bigger,difference was statistically significant (P<0.05), the Y-axis Angle decreased (P<0.01). ANS-Ptm (maxillary long), Co-Po (mandible long), SL are below normal groups, the difference was statistically significant (P<0.01). G-Sn-Po’ and G-Prn-Po’ will increased; ULP reduced, compared with the difference was statistically significant (P<0.01). The experimental group and control group between age, gender structure is balanced, no statistical difference; The different groups of data comparable. It is also found that the56cases has serious occlusal disturbance in adult patients, accounting for93.3%of the total.ConclusionsThe result show that, in hard tissue of the cleft palate patients,there were obvious deficiency of the maxillary development, the longth of the hard palate was too short, the mentum stretch before the mandibular phenomenon is obvious and the mandibular down rotation and back. In soft tissue of the cleft palate, the central in one third of the cleft palate patients’face develope insufficiently,upper lip protrusion insufficiently too.更多还原
