When managing extensive maxillary defects it is difficult to provide a stable biomechanical frame for prostheses, and obturators are difficult to use. This study reviews cases involving angular branch artery pedicled scapular bone flaps (SBF) combined with or without latissimus dorsi musculocutaneous flap (LDMF). Between 2004 and 2007, four wide maxillary defects were repaired using the angular vascularized branch of the scapular bone. Tumor resection with immediate reconstruction using combined LDMF and angular artery pedicled SBF was used in 3 cases and angular artery pedicled SBF alone in 1 case. Follow up was 6 months to 2 years. Satisfactory results were obtained for facial contour, appearance, speech, deglutition and breathing. No donor site complications or restricted shoulder movements were detected. The only complication was a minor infection of one flap. This procedure is useful, functionally and aesthetically, for reconstruction of wide extensive maxillary defects as bone supplied by the angular branch has a wider arc of rotation in relation to skin flaps and has a longer pedicle length from the axillary artery, long enough to reach the maxilla. This procedure also benefits from the flexibility of the soft tissue pedicle, such as the latissimus dorsi, serratus anterior and fasciocutaneous flaps.
当涉及广泛的上颌骨缺损时,为义齿提供稳定的生物力学框架很困难,而且闭塞器也难以使用。本研究回顾了涉及角支动脉蒂肩胛骨骨瓣(SBF)联合或不联合背阔肌肌皮瓣(LDMF)的病例。2004 年至 2007 年间,使用肩胛骨的角血管化分支修复了 4 例广泛的上颌骨缺损。3 例采用联合 LDMF 和角动脉蒂 SBF 的即刻肿瘤切除和重建,1 例采用角动脉蒂 SBF 单独重建。随访 6 个月至 2 年。面部轮廓、外观、言语、吞咽和呼吸均获得满意效果。未发现供区并发症或肩部活动受限。唯一的并发症是一个皮瓣的轻微感染。这种方法在功能和美学上对于广泛的上颌骨缺损的重建是有用的,因为角支供应的骨具有相对于皮瓣更大的旋转弧度,并且从腋动脉到骨的蒂长足够长,足以到达上颌骨。这种方法还受益于软组织蒂的灵活性,如背阔肌、前锯肌和筋膜皮瓣。
