Objective:To evaluate the clinical efficacy of endoscopic repair of medial orbital wall fractures using an autogenous ethmoid perpendicular plate-septal cartilage complex. Methods:A total of 27 patients with medial orbital wall fractures who underwent endoscopic reconstruction using the ethmoid perpendicular plate-septal cartilage complex were enrolled in Department of Otolaryngology, the Third Affiliated Hospital of Anhui Medical University[the First People's Hospital of Hefei]. The follow-up period was at least 6 months. Improvements in diplopia, restricted ocular motility, enophthalmos, and orbital volume were assessed before and after surgery. Results:All surgeries were successfully completed, with no complications such as infection, graft displacement, or vision loss observed during the follow-up period. Postoperative CT scans showed restoration of the structural continuity of the medial orbital wall. Diplopia, ocular motility disorders, and enophthalmos significantly improved in all patients. Compared to the preoperative measurements, the postoperative reduction in the orbital volume difference between the normal and fractured orbits was statistically significant （mean reduction:[1.54±0.93] cm³, P<0.05）. Postoperatively, the mean volume difference between the healthy and affected sides was not statistically significant （mean difference:[0.78±0.41]cm³，P＝0.287）, indicating that the orbital volume on the affected side approached that of the contralateral side. Conclusion:Endoscopic repair of medial orbital wall fractures using an autologous composite graft of the perpendicular plate of the ethmoid bone and nasal septal cartilage demonstrates favorable surgical outcomes. 目的：探讨鼻内镜下自体筛骨垂直板鼻中隔软骨复合体治疗眼眶内侧壁骨折的临床疗效。 方法：收集安徽医科大学第三附属医院（合肥市第一人民医院）耳鼻咽喉科27例行鼻内镜下筛骨垂直板软骨复合体眼眶重建术的眶内侧壁骨折患者。随访时间至少6个月。评估手术前后复视、眼球运动障碍、眼球内陷、眼眶容积的改善情况。 结果：所有手术均成功完成，随访期间未出现感染、移植物移位或视力下降等并发症，术后CT扫描显示眶内侧壁结构连续性恢复。所有患者复视、眼球运动障碍、眼球内陷显著改善。与术前比较，术后正常眼眶与骨折眼眶容积差异的降低程度有统计学意义（P<0.05），差异变化均值为（1.54±0.93） cm³，术后健侧和患侧的平均眼眶容积差异无统计学意义（P=0.287），差异均值为（0.78±0.41）cm³，表明患侧眼眶容积接近健侧水平。 结论：鼻内镜下采用自体筛骨垂直板鼻中隔软骨复合体修复眶内侧壁骨折，手术效果较好。.
