Abstract
Background/Objectives: Orbital fractures are common facial injuries that require precise reconstruction to restore both function and esthetics. Heterologous cortical lamina and titanium preformed meshes are widely used for orbital wall reconstruction; however, comparative data on their outcomes remain limited. Methods: This retrospective observational study analyzed 67 patients treated for orbital fractures at Santa Maria Hospital, Terni, between January 2021 and November 2024. Patients underwent orbital reconstruction using either a heterologous cortical lamina or titanium mesh. Clinical data, including demographics, trauma etiology, fracture characteristics, surgical approach, and postoperative complications were collected. Outcomes such as diplopia, enophthalmos, ocular motility, and sensory impairment were assessed preoperatively and postoperatively and compared between groups. Statistical analyses included Chi-square and Mann-Whitney U tests, with logistic regression to identify risk factors for complications. Results: Accidental falls were the leading cause of injury (46.3%), with the orbital floor being the most commonly affected site (83.6%). Postoperative complications occurred in 15% of patients, with diplopia significantly reduced from 47.8% preoperatively to 10.4% postoperatively (p < 0.05). Sensory impairment and motility restrictions also improved significantly. Patients reconstructed using heterologous cortical lamina experienced significantly fewer postoperative complications compared to those treated with titanium mesh (OR = 0.171, 95% CI: 0.023-0.799, p = 0.040). Conclusions: Both heterologous cortical lamina and titanium mesh provide effective orbital reconstruction; however, the heterologous cortical lamina was associated with fewer postoperative complications, particularly diplopia and sensory impairment. Material selection should consider the fracture complexity, patient characteristics, and potential long-term outcomes.
