Fracture of orbital floor — Clinical Guidelines

Overview

Orbital floor fractures result from trauma leading to bony disruption of the orbital floor, often causing functional and aesthetic issues including enophthalmos, diplopia, and periorbital swelling. 1 7

Diagnosis

Clinical Presentation: Periorbital ecchymosis, edema, diplopia, enophthalmos, and infraorbital nerve symptoms. 7

Imaging: CT scans are essential for identifying fractures, assessing bony defects, and evaluating associated injuries. 2 7

Anatomical Variance: Age influences the morphology of orbital floor fractures; childhood fractures may differ significantly from adult cases. 2

Management

Surgical Repair: Customized implants (PSIs) and bioresorbable materials like P(L/DL)LA 70/30 plates are effective for large defects. 1 17

Endoscopic Techniques: Transantral endoscopic approaches offer precise visualization and repair. 15

Image Guidance: Intraoperative image guidance improves surgical accuracy in complex cases. 6

Postoperative Evaluation: Formal ophthalmology evaluation post-repair is debated; necessary for symptomatic patients or those with potential ocular injuries. 3 9

Special Populations

Pediatrics: Anatomical differences suggest tailored approaches; detailed imaging is crucial. 2

Elderly: Increased risk of comorbidities; careful assessment and management of associated injuries are necessary. 7

Key Recommendations

Utilize CT imaging for definitive diagnosis and planning of orbital floor fracture repair. (Evidence: Strong 2 7)

Consider customized implants or bioresorbable materials for repair of significant bony defects. (Evidence: Moderate 1 17)

Postoperative ophthalmology consultation should be individualized based on clinical symptoms and potential ocular injury risk. (Evidence: Moderate 3 9)

Employ intraoperative image guidance to enhance surgical precision in complex orbital fractures. (Evidence: Moderate 6)

Evaluate anatomical differences in pediatric patients to tailor surgical approaches appropriately. (Evidence: Moderate 2)
