本研究的目的是确定上颌骨快速扩张的矫形力是否会导致颅骨和上颌骨缝线发生显着的数量变化。 20 名需要快速上颌扩张作为综合正畸治疗一部分的患者（平均年龄为 12.3 ± 1.9 岁）接受了扩张前和扩张后计算机断层扫描。在每位患者扩张前和扩张后计算机断层扫描的轴向、冠状或矢状切片之一上定位并测量了 10 条颅骨和环颌骨缝合线。使用 Wilcoxon 符号秩检验比较 2 次测量之间的定量变量。 P值小于0.05被认为具有统计显着性。上颌骨快速扩张导致颌间缝、鼻内缝、上颌骨缝、额颌缝和额鼻缝的宽度显着增加，而额颧缝、颧上颌缝、颧颞缝和翼上颌缝则表现出不显着的变化。颌间缝线宽度增加最大（1.7±0.9毫米），其次是鼻内缝线（0.6±0.3毫米）和上颌鼻缝线（0.4±0.2毫米）。中腭缝的宽度增加最大的是中切牙水平（1.6±0.8毫米），其次是尖牙水平（1.5±0.8毫米）和第一磨牙水平（1.2±0.6毫米）。与后部（颧骨界面）颅面结构相比，快速上颌扩张引起的力主要影响前缝线（颌间和上颌额鼻界面）。
The aim of this study was to determine whether the orthopedic forces of rapid maxillary expansion cause significant quantitative changes in the cranial and the circummaxillary sutures. Twenty patients (mean age, 12.3 ± 1.9 years) who required rapid maxillary expansion as a part of their comprehensive orthodontic treatment had preexpansion and postexpansion computed tomography scans. Ten cranial and circummaxillary sutures were located and measured on one of the axial, coronal, or sagittal sections of each patient’s preexpansion and postexpansion computed tomography scans. Quantitative variables between the 2 measurements were compared by using the Wilcoxon signed rank test. A P value less than 0.05 was considered statistically significant. Rapid maxillary expansion produced significant width increases in the intermaxillary, internasal, maxillonasal, frontomaxillary, and frontonasal sutures, whereas the frontozygomatic, zygomaticomaxillary, zygomaticotemporal, and pterygomaxillary sutures showed nonsignificant changes. The greatest increase in width was recorded for the intermaxillary suture (1.7 ± 0.9 mm), followed by the internasal suture (0.6 ± 0.3 mm), and the maxillonasal suture (0.4 ± 0.2 mm). The midpalatal suture showed the greatest increase in width at the central incisor level (1.6 ± 0.8 mm) followed by the increases in width at the canine level (1.5 ± 0.8 mm) and the first molar level (1.2 ± 0.6 mm). Forces elicited by rapid maxillary expansion affect primarily the anterior sutures (intermaxillary and maxillary frontal nasal interfaces) compared with the posterior (zygomatic interface) craniofacial structures.
