Advancement of the midface using distraction techniques

Fourteen patients underwent Le Fort III midface advancement using distraction techniques. Six have cephalometric documentation extending beyond 1 year postoperatively, and the positions of cephalometric points A and orbitale over time are reported here. Excellent stability of advancement at the occlusal level and some relapse at the level of orbitale are documented. Elimination or diminution of obstructive sleep apnea occurred in all patients so affected, and one of two patients with tracheostomy has been decannulated. Speech effects have been mild or transient. No untoward effects on extraocular muscle function have occurred.
