ABSTRACT
NERVES OF THE NECK 2. When performing surgery in the neck, which one of the following statements is
true regarding the marginal mandibular nerve? A. It normally travels 1 cm below the lower mandibular border throughout its course. B. It can be identified in the supraplatysmal plane as it passes anteromedially across the neck. C. Iatrogenic damage is unlikely to occur during neck rejuvenation surgery, as the nerve is
away from the operative field. D. Inadvertent nerve transection will cause denervation of the platysma, risorius, and lower lip
depressors. E. The nerve is most at risk of damage within a circle with a 2 cm radius, inferior and posterior
to the oral commissure.
