      Anterior maxillary osteotomy (AMO) has reported by Cohn-Stock in 1921, modified methods such as Wassmund, Cuper, Wunderer, and Epker methods have been described

      . However, it has been reported that periodontal tissue atrophy or partial necrosis may occur due to blood supply problems in the anterior segment3,

      . In fact, we have encountered cases of periodontal tissue atrophy (Fig. 1). Therefore, we established a novel AMO strategy to further improve the blood supply in the periodontal tissues near the osteotomy line.
