Influence of different types of guns, projectiles, and propellants on patterns of injury to the viscerocranium.
Gunshot injuries to the oral and craniomaxillofacial region vary with the type of gun used. Computed tomography (CT) is the standard diagnostic tool for assessing tissue damage in patients with gunshot injuries. Cone-beam computed tomography (CBCT) is a new imaging technique that has recently become available for clinical diagnosis. The objective of this study was to characterize injury patterns with a focus on gun types and identify the imaging modality that is best suited to assessing injuries caused by different gun types. ⋯ Every gun/projectile combination is associated with a typical pattern of injury. Even in the absence of the offending projectile, it is thus possible to narrow down the likely gun and/or projectile. In the diagnostic imaging of injuries caused by high-density projectiles, CBCT is more suitable than CT.

Controlled Clinical TrialPreventing pressure sores of the nasal ala after nasotracheal tube intubation: from animal model to clinical application.
Nasal-ala pressure sores induced by nasotracheal intubation are common complications of oral and maxillofacial surgery, but are easily ignored. To determine whether such sores could be prevented, we studied the effects of a combination of cushioning material in an animal model, and then analyzed the efficacy of this combination clinically. ⋯ We found that the combined use of Soft Liner and DuoDERM reduced the size and severity of nasal-ala pressure sores attributable to nasotracheal intubation during oral and maxillofacial surgery.
