Randomized Controlled Trial Comparative StudyPropofol dose-dependently increases bite force during sedation.
The purpose of this study was to investigate the dose-dependent effects of propofol on cognitive function and muscle power as well as vital functions. ⋯ Although the detailed mechanisms are unknown, propofol dose-dependently increases bite force during minimal and moderate sedation.

Transoral open reduction with rigid internal fixation for subcondylar fractures of the mandible using a small angulated screwdriver system: is endoscopic assistance necessary?
Although endoscopically assisted transoral open reduction and internal fixation of condylar mandible fractures is currently a popular technique, the need for it and its benefits remains unclear. This prospective study evaluated the efficacy and safety of open reduction and rigid internal fixation of subcondylar fractures of the mandible using a new small angulated screwdriver system without endoscopic assistance. ⋯ The surgical treatment of linear subcondylar fractures of the mandible can be achieved with an intraoral approach alone, using a small angulated screwdriver system, without endoscopic assistance, offering reliable clinical results and safe and minimally invasive surgery.

Comparative StudyComparison of 1-point fixation with 2-point fixation in treating tripod fractures of the zygoma.
Zygomatic tripod fracture is relatively common and generally requires open reduction-internal fixation through several incisions. However, lateral eyebrow incisions have sometimes left unsightly scars, and thus we have used 1-point fixation through a buccogingival incision so as not to leave scars in selected cases. The aim of this study was to compare 1-point fixation in the zygomaticomaxillary (ZM) area with 2-point fixation in the ZM and frontozygomatic (FZ) areas in tripod fractures. ⋯ One-point fixation in the ZM area in zygomatic tripod fractures can avoid unsightly scars and give high satisfaction with surgical outcomes in selected patients with tripod fractures.
