Accurate measurement of orbital volume after fracture is key in improving intraocular correction. OBJECTIVE: This study aims to explore the impact of 3D reconstruction technology in restoring normal exophthalmos in patients with old orbital wall fractures. METHODS: A total of 31 patients were randomly divided into an experimental group (n= 15) and a control group (n= 16). For orbital wall repair and reconstruction, the conventional group used the conventional surgical scheme, and the 3D group used 3D printing technology. RESULTS: There was no statistical difference between the preoperative mean extraocular muscle volume of the healthy eye and the affected eye. However, the mean orbital volume (24.76 vs 27.11, P= 0.005) and mean retrobulbar fat volume (17.53 vs 16.42, P= 0.006) were significantly different between the healthy eye and the affected eye. After an average follow-up of 16 weeks, the differences in pre- and post-surgery exophthalmos in the two groups were 0.42 \u00b1 0.08 mm and 1.63 \u00b1 0.51 mm, respectively. The difference between the two groups was statistically significant (t= 4.42, P= 0.003). The complications were not statistically different. CONCLUSION: Using 3D reconstruction technology preoperatively can significantly improve exophthalmos in patients with old orbital wall fractures.<\/jats:p>","DOI":"10.3233\/thc-220245","type":"journal-article","created":{"date-parts":[[2023,3,24]],"date-time":"2023-03-24T12:38:18Z","timestamp":1679661498000},"page":"1647-1657","source":"Crossref","is-referenced-by-count":1,"title":["A
