Modeling aberrant wound healing using tissue-engineered skin constructs and multiphoton microscopy.
Keloids and hypertrophic scars result from aberrant wound healing and remain a potential complication of any surgical procedure or trauma. Investigation of aberrant wound healing has been limited to the study of growth factors, collagen precursors, and DNA synthesis in simple in vitro systems, which necessitate removal or destruction of cells or factors in the growth environment of cell cultures. Multiphoton microscopy (MPM) can use endogenous chromophores such as collagen and nicotinamide adenine dinucleotide hydrogenase to produce thin optical sections of thick living tissues without the use of dyes or stains. Endogenous second-harmonic-generation (SHG) signals in collagen can be collected to form an MPM image. ⋯ The MPM model described herein permits serial observation of the same intact specimens without the need for fixation or cytotoxic stains. Furthermore, it demonstrates the biologic activity of RAFT artificial tissue constructs.

Endoscopically assisted repair of subcondylar fractures of the mandible: an evolving technique.
To review one surgeon's experience with the endoscopic approach to assist with reduction and rigid fixation of subcondylar fractures of the mandible. ⋯ The endoscopically assisted approach for the repair of subcondylar fractures of the mandible is a feasible but challenging technique.

Effect of air bags and restraining devices on the pattern of facial fractures in motor vehicle crashes.
To examine the relationship between the use of restraining devices and the incidence of specific facial fractures in motor vehicle crashes. ⋯ Use of restraining devices in vehicles significantly reduces the chance of incurring facial fractures in a severe motor vehicle crash. However, use of air bags and seat belts does not change the pattern of facial fractures greatly except for ZMC fractures. Air bags are least effective in preventing ZMC fractures. Improving the mechanics of restraining devices might be needed to minimize facial fractures.
