Materials used for reconstruction after orbital floor fracture

The field of orbital floor reconstruction remains uncertain about the optimal material to use. While multiple biomaterials have been proposed, no single material has been consistently shown to outperform others. Prior research has shown that autologous grafts, synthetic polymers, and composite materials are all in clinical use. However, no prior work had resolved the comparative safety and effectiveness of these materials. This gap motivated a systematic review to clarify the evidence base. Surgeons often rely on personal experience rather than robust data when choosing materials. The lack of standardized criteria for material selection has led to inconsistent outcomes. Preoperative and postoperative complications such as diplopia and enophthalmos remain poorly understood in relation to material choice. This uncertainty has driven the need for a broader synthesis of available literature.

The aim of this study was to evaluate the evidence supporting the use of various materials for orbital floor reconstruction. The authors sought to analyze the risks and benefits of each material to guide clinical decision-making. A decision-making algorithm was proposed to help surgeons choose materials based on available data. The study focused on comparing infection rates, ocular motility outcomes, and postoperative complications. No prior work had systematically reviewed all available materials in this context. The authors aimed to highlight inconsistencies in the literature and suggest areas for future research. They wanted to move beyond anecdotal evidence and surgeon preference. Their goal was to provide a structured approach to biomaterial selection in orbital surgery.

The study employed a systematic literature review approach. A total of 48 studies were selected after primary and secondary screening. Inclusion and exclusion criteria were applied to ensure the quality and relevance of the data. The selected studies collectively represented 3,475 orbital floor reconstructions. The authors analyzed the risk and benefit profiles of each material. They categorized materials into autologous grafts, synthetic polymers, and composite materials. Infection rates, diplopia, and enophthalmos were among the key outcomes measured. The data were synthesized to create a decision-making algorithm for clinical use.

The most widely used materials were autologous calvarial bone grafts, porous polyethylene, and polydioxanone (PDS). Infection rates were highest with polyglactin 910/PDS composites and silastic rubber. Ocular motility was most reduced with lyophilized dura and PDS. Preoperative and postoperative rates for diplopia and enophthalmos varied significantly among materials. No single material showed consistent superiority in all outcomes. The data revealed a lack of strong evidence to support exclusive use of any one material. The authors identified a need for more comparative studies between materials. Their findings supported the development of a decision-making algorithm for surgeons.

The authors concluded that the current evidence does not support the exclusive use of any one biomaterial for orbital floor reconstruction. They emphasized the need for further comparative studies to clarify the best options. The results have led to the creation of a decision-making algorithm for clinical application. Surgeons should consider infection risk, ocular motility, and postoperative complications when selecting materials. No prior work had resolved the comparative safety and effectiveness of these materials. The authors propose specific parameters for future studies comparing two or more materials. Their findings highlight the importance of evidence-based decision-making in this field. The study underscores the need for more standardized and comprehensive research.
