Transmucosal Pterygomaxillary Separation in the Le Fort I Osteotomy.

Abstract:

:The Le Fort I osteotomy is a versatile operation for correction of developmental, congenital, and posttraumatic deformities of the lower midface. One of the challenges of the osteotomy is pterygomaxillary separation, with the potential for unfavorable fractures to the orbit/skull base or vascular injury. A modified technique for pterygomaxillary disjunction is the transmucosal tuberosity osteotomy. The authors have used this technique for pterygomaxillary separation in 200 consecutive Le Fort I osteotomies over a 3-year period (2014 to 2017). There were no episodes of unfavorable propagation to the skull base or orbit, oroantral or oronasal fistulae, excessive bleeding/vessel injuries, or vascular insufficiency to the maxilla. The transmucosal tuberosity approach is a reliable and safe method of performing the pterygomaxillary separation during the Le Fort I osteotomy.
