Cleft Palate J. 1987 Jul;24(3):200-8.
Roentgencephalometry was used in a study of 30 boys and 30 girls with isolated cleft palate prior to palatoplasty. Their ages ranged from 3.5 to 4.5 years. These patients were compared with a control series and with a group of 20 boys with unilateral cleft lip and palate, examined similarly prior to palatoplasty. The isolated cleft palate (CP) group showed four basic differences from the control group: a shortening of maxillary depth and mandibular length (body and ramus), a reduction of the posterior height of the upper face, and a marked widening of the nasal cavity. In contrast to the unilateral cleft lip and palate group the CP group failed to demonstrate a shortening of the anterior height of the upper face or an elongation of the lower face. There was also no indication of a posterior displacement of the upper jaw, of a dentoalveolar retroinclination of the maxilla, or of an increase of the interocular distance. The observed shortening of both jaws in the CP group might be of importance in understanding the pathogenesis of isolated cleft palate. Unilateral cleft lip and palate was not associated with a reduction of the depth of the upper jaw, although the observed shortening of the lower jaw and of the posterior height of the upper face and the widening of the nasal cavity were similar to those seen in isolated cleft palate.
在腭裂修复术前，对30名孤立性腭裂男孩和30名孤立性腭裂女孩进行了X线头颅测量研究。他们的年龄在3.5岁至4.5岁之间。将这些患者与一个对照组以及一组20名单侧唇腭裂男孩进行比较，这组单侧唇腭裂男孩在腭裂修复术前也进行了类似检查。孤立性腭裂（CP）组与对照组相比有四个基本差异：上颌深度和下颌长度（体部和升支）缩短，上颌面部后部高度降低，鼻腔明显增宽。与单侧唇腭裂组相比，CP组未表现出上颌面部前部高度缩短或下颌面部伸长。也没有迹象表明上颌骨后移、上颌牙牙槽后倾或两眼间距增加。CP组观察到的上下颌缩短可能对理解孤立性腭裂的发病机制具有重要意义。单侧唇腭裂与上颌骨深度减小无关，尽管观察到的下颌缩短、上颌面部后部高度降低以及鼻腔增宽与孤立性腭裂所见相似。
