Cleft Palate Craniofac J. 1994 Sep;31(5):376-84. doi: 10.1597/1545-1569_1994_031_0376_pcalsi_2.3.co_2.
This study concerns palatal development during 6 months following primary lip closure. The sample consisted of 75 children with different forms of cleft lip and palate and 51 noncleft children. The palate was measured at 3 months of age, just before lip surgery, after surgery at 6 months, and again at 9 months of age. The results showed that lip closure has a strong effect in the anterior alveolar region. This effect was restricted to 3 months after surgery. The changes in complete clefts were more explicit than in incomplete cleft forms. Furthermore, the data showed that arch depth reduction due to lip surgery was compensated for by continued anteroposterior palatal growth. Early orthopedics appeared to prevent major palatal collapse immediately after lip surgery. Finally simultaneous closure of the alveolar cleft at the nasal side resulted in continued reduction of anterior cleft width.
本研究关注一期唇裂修复术后6个月内的腭部发育情况。样本包括75名患有不同形式唇腭裂的儿童和51名非唇腭裂儿童。在患儿3个月龄时，即唇裂修复手术前、术后6个月以及9个月龄时分别对腭部进行测量。结果显示，唇裂修复手术对前牙槽区域有显著影响。这种影响仅限于术后3个月。完全性腭裂的变化比不完全性腭裂更为明显。此外，数据表明，唇裂修复手术导致的牙弓深度减小可通过腭部前后径的持续生长得到补偿。早期正畸治疗似乎可预防唇裂修复手术后腭部的严重塌陷。最后，鼻侧牙槽裂的同期关闭可使前部裂隙宽度持续减小。
