Abstract

This case report documents a patient with a Class II skeletal malocclusion and suspected obstructive sleep apnea who underwent a combined mandibular inverted L osteotomy and total subapical osteotomy. The surgery involved a single-piece Lefort 1 osteotomy of the maxilla, bilateral inverted L osteotomies of the mandible, and a total mandibular subapical osteotomy. After the patient's pre-surgical orthodontic phase was completed, a traditional bilateral sagittal split osteotomy (BSSO) was initially planned to achieve mandibular advancement. However, the large horizontal and yaw correction required for the patient's mandibular teeth made a BSSO alone unrealistic. The virtual surgical plan (VSP) indicated that a subapical osteotomy was necessary, and due to the extension of the total subapical segment, an inverted L osteotomy was added to benefit the subapical osteotomy. The patient's surgery was successful, and the results were satisfactory.

下颌倒 L 型截骨术和下颌角下全切骨术联合应用

本病例报告记录了一名患有二类骨骼错合畸形和疑似阻塞性睡眠呼吸暂停的患者，她接受了下颌骨倒 L 型截骨术和全下颌角下截骨术。手术包括上颌骨单块Lefort 1截骨术、双侧下颌骨倒L截骨术和下颌骨根尖下全截骨术。患者的术前正畸阶段结束后，最初计划采用传统的双侧矢状劈开截骨术（BSSO）来实现下颌前突。然而，由于患者下颌牙齿需要进行较大的水平和偏航矫正，因此仅靠 BSSO 是不现实的。虚拟手术计划（VSP）显示，有必要进行心尖下截骨，而且由于心尖下总段的扩展，还增加了倒 L 截骨，以利于心尖下截骨。患者的手术很成功，效果令人满意。
