The objective of this study was to investigate the effects of cleft palate itself on the growth of maxilla and mandible.
Fifty-two adult female patients with unoperated isolated cleft palate and 52 adult female individuals with normal occlusion were included in our study. Computer software was used for lateral cephalometry measurement. Manual measurement was performed for dental cast measurements, and sample t test analysis was applied to analyze the differences between the 2 groups using SPSS 17.0.
The sella-nasion-subspinale point angle, subspinale-nasion-supramentale point angle, and maxillary arch length of the cleft group were significantly smaller than those of the control group (P < 0.01). Both maxillary and mandibular posterior dental arch widths of the cleft group were significantly larger compared with the control group (P < 0.01), whereas the sella-nasion-supramentale point angle, mandible arch length, palate height, and palate shelf inclination did not differ between the 2 groups. The measurements did not differ between the submucosal cleft and the overt cleft patients.
Cleft palate itself has adverse effects on the maxilla growth with shorter maxillary arch length and wider posterior dental arch width.
本研究旨在探讨腭裂本身对上颌骨和下颌骨生长的影响。
本研究纳入了52例未接受手术的成年女性孤立性腭裂患者和52例咬合正常的成年女性个体。使用计算机软件进行头影测量。对石膏模型进行手工测量，并应用样本t检验分析，使用SPSS 17.0分析两组之间的差异。
腭裂组的蝶鞍-鼻根-前鼻棘点角、前鼻棘-鼻根-颏下点角和上颌弓长度均显著小于对照组（P < 0.01）。腭裂组的上颌和下颌后牙弓宽度均显著大于对照组（P < 0.01），而两组之间的蝶鞍-鼻根-颏下点角、下颌弓长度、腭高和腭板倾斜度无差异。黏膜下腭裂患者和完全性腭裂患者的测量结果无差异。
腭裂本身对上颌骨生长有不利影响，表现为上颌弓长度较短和后牙弓宽度较宽。
