Because intraoral and submental trajectories are almost always present in the setting of attempted suicide, this study sought to determine if intent (self-harm versus other-harm) influenced mortality in facial gunshot wound (GSW) patients.</p><p><strong>Methods: </strong>All patients with a diagnosis of a facial fracture secondary to firearm injury were included in the study sample. The primary predictor was self-harm. Secondary predictors were derived from patient, injury, and hospitalization characteristics. The study outcome was death.

As such, this article aims to review the indications and timing of repair, surgical approaches, materials used for repair, and contemporary adjuncts to repair. Indications for orbital floor fracture repair remain controversial as many of these fractures heal without intervention or adverse sequelae. Intraoperative navigation and imaging, as well as endoscopic guidance, can improve visualization of defects mitigating implant positioning errors, thereby reducing the need for secondary corrective procedures. Patient-specific implants may be constructed to fit the individual patient's anatomy using the preoperative CT dataset and mirroring the contralateral unaffected side and have been shown to improve pre-operative efficiency and minimize postoperative complications.
