Cleft Palate Craniofac J. 1993 Mar;30(2):175-81. doi: 10.1597/1545-1569_1993_030_0175_rbcsad_2.3.co_2.
Relationships between the width of the palatal cleft measured at palatoplasty and the craniofacial morphology or the occlusal conditions present at approximately 4 years of age were studied in 25 cleft palate (CP) and 39 complete unilateral cleft lip and palate (UCLP) subjects treated at the Dental Clinic of Kyushu University. Posteroanterior cephalograms and dental casts showed that the width of the palatal cleft was significantly correlated with wider upper facial width and posterior dental arch width in UCLP, but not in CP subjects. Cleft width was not significantly correlated with the buccolingual occlusal relationship in either subject type. The anterior occlusal relationship in UCLP was not as good as in CP subjects. On lateral cephalograms, the width of the palatal cleft was significantly correlated with vertical hypoplasia of the upper face in UCLP, but not in CP subjects. The cleft palate width appears to be related to the lateral displacement and the retardation of the downward and forward growth of the nasomaxillary complex in UCLP subjects.
在九州大学牙科诊所接受治疗的25名腭裂（CP）患者和39名单侧完全性唇腭裂（UCLP）患者中，研究了腭裂修复术中测量的腭裂宽度与大约4岁时的颅面形态或咬合情况之间的关系。正位头影测量片和牙模显示，腭裂宽度与UCLP患者较宽的上颌面部宽度和后牙弓宽度显著相关，但在CP患者中无此关联。在两种类型的患者中，腭裂宽度与颊舌向咬合关系均无显著相关性。UCLP患者的前牙咬合关系不如CP患者。在侧位头影测量片上，腭裂宽度与UCLP患者上颌面部的垂直发育不全显著相关，但在CP患者中无此关联。腭裂宽度似乎与UCLP患者鼻上颌复合体的侧向移位以及向下和向前生长的迟缓有关。
