Just a bit about the surgery. Here is a tracing of an individual with class 2 malocclusion. My personal tracing would be similar, except that I am not having surgery involving the maxilla. You can see how retruded the mandible is compared to the rest of the facial skeleton.
The BSSO involves sectioning the mandible and sliding it forward, careful not to damage the Inf. alveolar nerve (resulting in parasthesia to the lower lip and tongue- meaning you would loose feeling to those areas supplied by the nerve).
After sliding the mandible forward, a plate and screws are used to hold everything in place while the bone re-grows to fill in the empty space. The plate and screws are left in place - and no, it won't set off the metal detectors at the airport (I asked).
