Can all of these procedures be done in one surgery? 

In most cases, yes. A full plan combining forehead, nose, jaw, chin, and tracheal shave runs to roughly nine or ten hours of surgery, and we do this routinely for patients who are medically fit for it. 

Twelve hours is our limit, and that is what a full facial surgery looks like when something else is added to it, a breast augmentation for example. At the other end of the scale, the shortest standard surgery we perform is a tracheal shave on its own, at around an hour and a half.
