The Outcomes of Orbital Blowout Fracture Repairment by Transconjunctival Endoscopic Technique

Abstract

Objectives: The purpose of this case series is to present the benefits and results of using a transconjunctival endoscopic technique to repair orbital blowout fractures. Patients and methods: In this retrospective interventional case series, 133 patients with ocular blowout fractures were enrolled. Between January 2021 and December 2022, these patients underwent transconjunctival orbital blowout fracture repair using an endoscopic technique and a Medpor-Titanium sheet implant. Results: This study included 133 individuals (135 eyes) with orbital blowout fractures, 129 of whom were adults and 4 of whom were pediatric patients. 63 eyes had medial wall fractures, 23 eyes had inferior wall fractures, and 49 eyes had both types of wall fractures. Preoperative eyeball enophthalmos was 2.33 mm on average. In 132 eyes, postoperative exophthalmia improved by ≥2 mm, while it improved by < 2 mm in 6 eyes. After surgery, 73 individuals' diplopia disappeared one month after surgery. 42 patients' facial paresthesia recovered one to three months following surgery. After a 6-month follow-up, 131 out of 133 cases had been cured, and 2 had improved. There was a 100% effective rate and a 95.56% cure rate. Conclusion: This article details the results and experience of using a transconjunctival endoscopic technique to repair orbital blowout fractures. The procedure is efficient in restoring orbital structure and improving visual function, and it has a low rate of postoperative complications.
