Cephalometric assessment of the nasopharynx and its adjacent structures was carried out in two experimental groups of 5-year-old male patients with unilateral cleft lip and palate. The first group included individuals who had not had surgery, and the second was comprised of individuals who were at least 1 year postpalatoplasty with primary pharyngeal flap. They were compared with a control group of boys of comparable average age who did not have clefts. Both groups of patients with clefts showed a reduction of the nasopharyngeal bony framework related to the posterior position and decreased posterior height of the maxilla without hypertrophy of the adenoids. The smaller nasopharyngeal airway was consistent with the reduction of the size of the bony nasopharynx. There was shortening of the anterior cranial base located in the region of the middle cranial fossa. The height of the body of the sphenoid bone was reduced, but the angle of the cranial base was within normal limits.
对两组5岁单侧唇腭裂男性患者进行了鼻咽部及其相邻结构的头影测量评估。第一组包括未接受手术的个体，第二组由至少在腭裂修复术后1年且行一期咽瓣手术的个体组成。将他们与年龄相当、无腭裂的男性对照组进行比较。两组腭裂患者均显示与上颌骨后位相关的鼻咽骨框架减小，上颌骨后高度降低，且腺样体无肥大。较小的鼻咽气道与鼻咽骨大小的减小一致。位于中颅窝区域的前颅底缩短。蝶骨体高度降低，但颅底角度在正常范围内。
