Medial displacement of proximal segments. A complication to oblique sliding osteotomy of the mandibular rami.
In a retrospective study of 125 patients operated by oblique sliding osteotomy of the mandibular rami, unilateral medial displacement of the proximal segment was found in 10 patients. In 8 of these retropositioning of the distal segment during surgery was combined with lateral rotation and the amount of retropositioning was small. Medial displacement of the proximal segment had no influence on postoperative stability. In 6 of the 10 patients transient anesthesia for the inferior alveolar nerve was found on the side where the proximal segment was medially displaced.
