This study traces the changes in maxillary dimension in 44 unilateral cleft lip and palate (UCLP) patients and 28 bilateral cleft lip and palate (BCLP) patients from birth up to the time of palate surgery at age 3. Measurements on dental casts were carried out at 4 defined registration stages. The results revealed a continuous reduction in cleft dimension parallel to an increase in the transversal and sagittal maxillary dimensions. The inclination of the palatal slope displayed such a high degree of variability that no statement regarding the development in this variable could be made. Differences between the 2 types of cleft patients were found only in the maxillary sagittal dimension. Wearing an orthopedic plate after surgery appears to prevent transversal collapse in the anterior region and to counteract external transversal and sagittal forces. Only temporary inhibition of growth in the sagittal dimension of the maxilla was observed after lip surgery.
本研究追踪了44名单侧唇腭裂（UCLP）患者和28名双侧唇腭裂（BCLP）患者从出生到3岁腭裂手术时上颌尺寸的变化。在4个确定的记录阶段对石膏模型进行测量。结果显示，腭裂尺寸持续减小，同时上颌横向和矢状尺寸增加。腭斜率的倾斜度变化很大，无法对该变量的发育情况做出说明。仅在上颌矢状尺寸方面发现了两种腭裂患者之间的差异。术后佩戴矫形板似乎可防止前部区域横向塌陷，并抵消外部横向和矢状力。唇裂手术后仅观察到上颌矢状尺寸的生长受到暂时抑制。
