Comprehensive orthognathic correction of post-traumatic Le-Fort II deformity

摘要

The correction of post-traumatic craniofacial deformitiesis recognized as a challenge to experienced surgeons. Thereason for developing post-traumatic deformity of thecraniofacial skeleton can be categorized into two groups:those related to the fracture itself, severe comminutionand bone and soft tissue loss, and those related to thetreatment, excessively delayed initial treatment, a lack ofdefinitive treatment, inadequate initial surgical repair,and failure of hardware.1 Malocclusion after primarytreatment of maxillofacial trauma is not as frequentlyseen. The most common reason for malocclusion afterprimary midfacial trauma treatment is maxillary wideningor impaction, as the anteroposterior (AP) and/or transversal dimensions have been altered during the operation,and the occlusal plane might easily become oblique andtilted. In impacted maxilla, the impaction of the nose isusually the most disturbing subjective symptom for thepatient.
