title: Screw fixation following bilateral sagittal ramus osteotomy for mandibular advancement--complications in 700 consecutive cases.
abstract: The use of transbuccal positional screws for stabilisation of bony segments following bilateral sagittal split osteotomy for mandibular advancement was assessed in 700 consecutive cases. In 19 patients (2.7% of cases) screw fixation was not used as the method of fixation. Screw removal was performed in 20 patients (2.8% of cases), in 15 cases due to infection and 5 cases for diverse reasons. The incidence of inferior alveolar nerve damage was increased when compared to a group of patients managed with intermaxillary fixation following advancement BSSO treated in the same unit. In 4 patients (0.6%) a lingual nerve dysaesthesia occurred. Screw loosening in the first postoperative week occurred in 4 patients and in 3 of these re-operation was necessary. Extra oral scar formation did not give rise to any significant problems.
