Out of curiosity: Is this actually the fracture line of the type of Lefort III advancement Sinn also performs? Does he also perform the Lefort III including an upper jaw advancement as seen in this pic?
Reading a bit up on this stuff it could and change the orbital volume considerably. How does he make up for that?
Also seems like it would/could lengthen the midface somewhat. So the mandible should be rotated? What about the fracture in the nasal spine, how's that gonna heal?
