To evaluate the effects of cleft palate on the craniofacial morphology in adult patients with unoperated cleft palate by cephalometric analysis.
X-ray cephalometry was used for the study of craniofacial morphology carried out in 7 male and 8 female patients with unoperated cleft palate. Pointing measurements were done with the methods of Downs and Steiner. The data of the cephalometric measurements were compared with that of Guangxi native normal adults by t test.
The unoperated cleft palate patient,s SNA,ANS-Ptm(FH) and L1-MP were smaller or shorter than those of normal group while Po-NB was longer. There was significant difference between the two groups (P<0.05 or 0.01).
The deformities of adult patients with unoperated cleft palate were mainly considered to be that the anterior and posterior length of maxilla show hypoplastic while the vertical height of the maxilla the length of anterior cranial fossa and mandible was normal. But the retrusion of alveolar mandible led to chin protrusion.
通过头影测量分析评估成年腭裂未手术患者的腭裂对颅面形态的影响。
采用X线头影测量法对7例男性和8例女性腭裂未手术患者的颅面形态进行研究。采用唐斯（Downs）和施泰纳（Steiner）法进行定点测量。通过t检验将头影测量数据与广西本地正常成年人的数据进行比较。
腭裂未手术患者的SNA、ANS-Ptm（FH）和L1-MP比正常组小或短，而Po-NB更长。两组之间存在显著差异（P<0.05或0.01）。
成年腭裂未手术患者的畸形主要表现为上颌前后长度发育不足，而上颌垂直高度、前颅窝长度和下颌骨正常。但牙槽突下颌后缩导致颏部前突。
