Eugene A. Chu, MD, and colleagues determine the degree of facial asymmetry required to trigger a perception of facial paralysis by an observer. They do this by digitally manipulating the image of a person without facial paralysis. Progressive asymmetry of various parts of the face was performed, and observers naive to the goals of the study were asked to analyze the images. The study provides insight into the amount of facial asymmetry required to trigger conscious perception of facial paralysis.
Curtis Gaball, MD, and colleagues analyze the use of a bioabsorbable bone plate made of polymer L/DL-lactide 70/30 for bony fracture repair. Although this material lacks the stiffness of titanium, a bioabsorbable implant with sufficient strength may prevent the unwanted adverse effects of a titanium implant. Using a finite element model of the mandible, the authors determine whether the absorbable plate can provide the same mechanical stability as a titanium plate and also study ways to optimize the use of the plate.
Kofi D. Boahene, MD, and colleagues describe a minimally invasive version of the temporalis tendon transposition, which is used for immediate dynamic reanimation in patients with long-standing facial paralysis. They present the surgical technique as well as analysis of the results, including analysis of symmetry, oral competence, and dynamic oral commisure movement.
Mia E. Miller, MD, and colleagues present their data on whether preoperative magenetic resonance angiography (MRA) is predictive of surgical findings in fibula free flap surgery for head and neck reconstruction. In blinded fashion, radiologists reviewed MRAs, with close attention to perforator vessels. The authors analyze the correlation between MRA studies and actual findings in the operating room.
