[Posttraumatic orbital defect correction with bone autografts].

Area of Science:

• Plastic Surgery
• Ophthalmology
• Trauma Surgery

Background:

• Post-traumatic orbital defects require reconstructive solutions.
• Bone autografts are a common method for orbital reconstruction.
• Assessing the safety and outcomes of these grafts is crucial.

Purpose of the Study:

• To evaluate the safety and efficacy of bone autografts in correcting post-traumatic orbital defects.
• To analyze outcomes in patients with isolated orbital deformities versus complex midface injuries.
• To present a diagnostic algorithm for orbital trauma management.

Main Methods:

• Retrospective study of 69 patients undergoing orbital defect correction.
• Use of membranous bone autografts with soft tissue hypercorrection (bone chips and platelet-rich plasma).
• Categorization into isolated orbital deformities (n=21) and complex midface injuries (n=48).

Main Results:

• Ocular vessel hemodynamics improved one year post-surgery.
• Complex midfacial injuries (Group 2) showed restricted ocular mobility and increased diplopia.
• Subciliary approach led to lower lid retraction, negatively affecting esthetic results.

Conclusions:

• Bone autografts can be safely used for orbital defect correction.
• Complex midface injuries present unique challenges and potential complications.
• Further refinement of surgical techniques may improve esthetic and functional outcomes.
