Three-Dimensional Diagnosis in Orbital Reconstructive Surgery.

Area of Science:

• Ophthalmology
• Plastic Surgery
• Medical Imaging

Background:

• Orbital floor fractures are common mid-face injuries requiring reconstruction to restore orbital volume and anatomy.
• Implant malpositioning and inadequate volume restoration are frequent complications in traditional orbital reconstruction.
• Patient-specific virtual planning offers a novel approach to enhance surgical outcomes.

Purpose of the Study:

• To evaluate the surgical outcomes of orbital reconstruction using patient-specific virtual planning.
• To compare the efficacy of virtual planning against traditional methods in managing orbital wall fractures.

Main Methods:

• A comparative study involving 77 patients with orbital wall fractures.
• Group A (42 patients) underwent virtual planning-assisted reconstruction; Group B (35 patients) received traditional reconstruction.
• Outcomes were assessed by postoperative diplopia and surgical procedure duration.

Main Results:

• While initial diplopia rates were similar, 6-month residual diplopia was significantly lower in the virtual planning group (9.5% vs. 34.3%).
• Virtual planning led to reduced mean operation times across isolated zygoma, isolated orbital wall, and combined fractures.
• Specific mean operation times were 2.23h (Group A) vs. 3.47h (Group B) for isolated zygoma fractures.

Conclusions:

• Virtual planning significantly enhances postoperative outcomes in orbital reconstruction.
• The technology's application may be limited in highly complex orbital wall defects requiring intricate implant designs.
• Patient-specific virtual planning represents a valuable advancement for improving orbital reconstruction results.
