OBJECTIVES: The purpose of this study is to evaluate the demographics of patients with orbital blow-out fractures, as well as the success and complications of surgical repair with porous polyethylene membrane sheet implants through transcon-junctival technique and to compare the results to previously published studies.
METHODS: This retrospective study included 57 patients diagnosed with orbital blow-out fractures referred to our clinic between 2018 and 2022. Seventeen patients (29.8%) underwent orbital fracture repair through a transconjunctival tech-nique employing porous polyethylene membrane sheets. The indications for surgery were enophthalmos >2 mm and persistent ocular motility restriction, diplopia, and strabismus. The success criteria were <2 mm of enophthalmos and complete correction of eye motility, diplopia, and strabismus.
RESULTS: The study group consisted of ten females and 47 males with a mean age of 31.12 years. The most common cause of injury was assaults (50.9%), followed by falls (38.6%), traffic accidents (5.3%), and accidental impacts (5.3%). The inferior wall (61.4%) was the most common fracture site, followed by the medial wall (21.1%) and a combination of the inferior and medial walls (21.1%). The surgically treated group showed a significant improvement in ocular motility restriction (88.2–23.5%, p=0.002), diplopia (70.6–23.5%, p=0.008), and enophthalmos (1.41 mm to 0.82 mm, p=0.012) after surgery. The surgery was successful in ten of 17 cases (58.8%), and the success rate was higher in patients who were treated early (77.8% vs. 37.5%), but the difference was not statistically significant (p=0.092).
DISCUSSION AND CONCLUSION: Orbital blow-out fracture repair using porous polyethylene membrane sheets through a transconjunctival approach is a safe and effective surgical technique for orbital blow-out fracture repair. Although patients who had early surgery had a higher success rate in our study group, larger study groups are needed to assess the effect of surgical timing on success.
