本文通过对３３名单侧完全性唇腭裂术后反及２９名普通反患者进行Ｘ线头影测量比较研究发现，两组患者虽然均存在颌间关系不调及前牙反，但机制却不尽相同。唇腭裂组患者上颌向前发育更差且上颌位置更偏远中。而下颌位置，突度基本正常。但普通及下颌突度较大。唇腭裂患者ＰＦＨ／ＴＦＨ较小，表明其面部生长呈开张型。其软组织面型更凹，软组织补偿机制较差。
In this paper, after 33 pairs of unilateral complete cleft lip and palate patients with anti-29 and anti-routine anti-X-cephalometry comparison study found that although there are two groups of patients with no intermaxillary relationship and anterior crossbite, but the mechanism is not the same . Patients in the cleft lip and palate group had a worse maxillary forward development and a more distal maxillary position. The jaw position, the degree of disruption is basically normal. But the common and jaw greater than the sudden. Cleft lip and palate patients PFH / TFH smaller, suggesting that the facial growth was open type. Its soft tissue surface is more concave, soft tissue compensation mechanism is poor.
