Cleft Palate J. 1977 Jan;14(1):52-62.
Between the ages of six months and six years, longitudinal lateral headfilms were taken on 54 patients with palatal clefts or with unilateral and bilateral clefts of the lip and palate. They were measured and were compared to data on both normals and subjects with clefts of the lip only. The objectives of the study were: 1. To sutdy the effects of palatal surgery on the growth of the soft palate. 2. To compare the growth of the soft palate and nasopharynx among the patients with various types of clefts and normals. 3. To study the growth acceleration or so-called catch-up growth after palatal surgery at various ages. (Anterior palatal surgery at 14 months +/- 2 months. Posterior palatal surgery at 16 months +/- 2 months.) 4. To evaluate the relationship between velopharyngeal growth in cleft groups and voice quality.
在6个月至6岁之间，对54例腭裂或唇腭裂（包括单侧和双侧）患者拍摄了头颅侧位片。对这些片子进行了测量，并与正常人和单纯唇裂患者的数据进行了比较。该研究的目的是：1. 研究腭裂手术对软腭生长的影响。2. 比较不同类型腭裂患者与正常人软腭和鼻咽部的生长情况。3. 研究不同年龄腭裂手术后的生长加速或所谓的追赶生长情况。（前腭裂手术在14个月±2个月进行。后腭裂手术在16个月±2个月进行。）4. 评估腭裂组腭咽生长与语音质量之间的关系。
