A case of anterior skeletal open bite was successfully treated with a sagittal osteotomy of the mandibular horizontal ramus. Advantages of this technique are good access and ease of surgery, broad medullary contact at osteotomy sites, and elimination of the need for a bone graft. Close cooperation between speech pathologist and surgeon is essential when apertognathia is acquired by tongue-thrust or abnormal oral habits. Removal of causal factors and adequate immobilization will reduce the chance for relapse often seen in open bite surgery.
一例前牙骨性开颌病例通过下颌水平支矢状骨切开术成功治疗。该技术的优点是手术入路良好且操作简便，截骨部位有广泛的骨髓接触，并且无需植骨。当因舌前伸吞咽或异常口腔习惯导致开合时，言语病理学家与外科医生密切合作至关重要。消除病因并进行充分固定将减少开颌手术中常见的复发几率。
