Frontal Bone Fracture Patterns Suggesting Involvement of Optic Canal Damage.

Purpose: Fracture of the frontal bone can be accompanied by damage to the optic canal. The present study uses finite element analysis to identify fracture patterns, suggesting the involvement of the optic canal.

Methods: Ten finite-element skull models were generated from computer tomography data of 10 persons.

Separation patterns of orbital wall and risk of optic canal injury in Le Fort 3 osteotomy.

Purpose: The authors hypothesized that the risks of optic canal injury in down-fracturing after Le Fort 3 osteotomy vary depending on the separation patterns of the orbital walls. This study verifies this hypothesis using biomechanical simulation.

Methods: Ten finite-element skull models were produced using computer tomography data from ten persons.
