%X <B>OBJECTIVE: </B>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.<BR><B>METHODS: </B>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.<BR><B>RESULTS: </B>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).<BR><B>CONCLUSIONS: </B>The maxillary skeletal expander slightly expanded the orbital volume in the adult female patients and increased the lateral widths of the periorbital bones.<BR>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。.
