Sagittal splitting ramus osteotomy is now a widely used procedure in orthognatic surgery. The techniques are well standardized and carry a low complication rate. Neurological complication resulting from mandibular osteotomy can be found in the inferior alveolar and mental nerves.
In this report, peripheral facial nerve palsy is discovered in a male patient with cleft lip and palate who underwent bilateral sagittal splitting ramus osteotomy for the correction of an anterior open bite associated with mandibular prognathism.
A possible mechanism pertinent to this distressing complication is discussed.
