Predictability in orbital reconstruction: A human cadaver study. Part I: Endoscopic-assisted orbital reconstruction

摘要: In the treatment of orbital defects, surgeon errors may lead to incorrect positioning implants and, consequently, poor clinical outcomes. Endoscopy can provide additional visualization orbit through transantral approach. We aimed evaluate whether endoscopic guidance during reconstruction facilitates optimal implant placement and serve as a convenient alternative for navigation intra-operative imaging. Ten human cadaveric heads were subjected thin-slice computed tomography (CT). Complex fractures (Class III/IV) created in all eligible orbits (n = 19), which then reconstructed using conventional transconjunctival approach with or without guidance. The ideal location was digitally determined pre-operative CT images, accuracy evaluated by comparing planned postoperative location. There no statistically significant differences (p > 0.05) degree dislocation (translation rotation) between endoscopic-assisted groups. Endoscopic-assisted facilitate defects is particularly useful training purposes; however, it offers benefits terms accurate anatomical complex defects.
