One side underwent a traditional sagittal split ramus osteotomy, and the procedure was modified on the other side by adding a 1\u00a0cm horizontal osteotomy at the lower border of the mandible, just distal to the caudal end of the vertical buccal osteotomy cut.

On the inferior border osteotomy sides, the distribution of LSS1, LSS2, LSS3, and LSS4 was 10 (25%), 6 (15%), 4 (10%), and 0 (00), respectively.
