{Abstract}: OBJECTIVE: The effects of using a maxillary skeletal expander (MSE) on the orbital volume and width between periorbital bones in the treatment of adult female patients with maxillary transverse deficiency (MTD) were evalua⁃ted.
METHODS: A total of 20 adult female patients with MTD with an average age of (22.60±6.29) years were included in the study. The patients were treated with MSE. Cone beam computed tomography was performed before expansion (T0) and no more than 3 weeks after expansion (T1). Orbital volume and periorbital bone width were measured with Mimics 21.0 and analyzed with SPSS 20.0. Paired t-test was performed, and a P value of <0.05 indicated significant difference.
RESULTS: After expansion, the orbital volume increased by (346.80±275.31) mm3 (P<0.05). The width between the right and left zygomaticomaxillary sutures increased by (1.69±0.57) mm (P<0.05), and the width between the right and left infraorbital points increased by (1.71±0.70) mm (P<0.05). However, the width between the right and left frontozygomatic sutures increased by (0.15±0.32) mm (P>0.05). Finally, the width between the right and left supraorbital points increased by (0.23±0.52) mm (P>0.05).
CONCLUSIONS: The maxillary skeletal expander slightly expanded the orbital volume in the adult female patients and increased the lateral widths of the periorbital bones.
目的: 评价上颌骨性扩弓器(MSE)治疗成年女性上颌骨宽度不足(MTD)对眼眶容积及眶周骨骼间宽度的影响。方法: 选取采用MSE治疗的MTD成年女性患者20例,年龄为(22.60±6.29)岁。分别于扩弓前(T0)和扩弓结束3周内(T1)拍摄锥形束CT,将数据导入Mimics 21.0软件,测量眼眶容积及眶周骨骼间宽度,采用SPSS 20.0软件进行统计分析,扩弓前后测量数据采用配对样本t检验,P<0.05为差异有统计学意义。结果: 扩弓后,眼眶容积增加(346.80±275.31)mm3,颧颌点间宽度增加(1.69±0.57)mm,眶下点间宽度增加(1.71±0.70)mm,差异有统计学意义(P<0.05);额颧点间宽度增加(0.15±0.32)mm,眶上点间宽度增加(0.23±0.52)mm,差异无统计学意义(P>0.05)。结论: MSE对成年女性眼眶容积有轻微的扩大效应,可增大眶周骨骼横向宽度。.
