In addition to prosthetic rehabilitation, maxillary defects can also be surgically reconstructed. Soft-tissue reconstruction employs a radial forearm or latissimus dorsi muscle flap, while bony reconstruction can be achieved using a fibula, iliac crest, or scapular flap. Reconstruction using a scapular flap is further divided into two subgroups: the traditional scapular flap with the circumflex scapular artery as the donor vessel and the scapular angle flap with the angular artery originating from the thoracodorsal artery as the donor vessel.
We report on four patients who underwent successful reconstruction with a free scapular angle flap between 2009 and 2011, following maxillary resection due to malignancy.
Vertical positioning of the scapular angle flap enables reconstruction of the facial contour, whereas its horizontal alignment and microvascular anastomosis makes a bony reconstruction of the hard palate possible.
The versatility, low rate of donor site morbidity and shape of the scapular angle flap--which resembles that of the hard palate--render it ideal for plastic reconstruction. The suitability of bone quality for dental rehabilitation with implants is a topic of controversial discussion. The scapular angle flap represents an alternative to obturator prosthesis for the reconstruction of maxillary defects ≥ grade I according to Okay et al.
除了假体修复外,上颌骨缺损也可通过手术进行重建。软组织重建采用桡侧前臂或背阔肌肌皮瓣,而骨重建可使用腓骨、髂嵴或肩胛皮瓣。肩胛皮瓣重建又进一步分为两个亚组:以旋肩胛动脉为供血血管的传统肩胛皮瓣和以源自胸背动脉的角动脉为供血血管的肩胛角皮瓣。
我们报告了2009年至2011年间4例因恶性肿瘤行上颌骨切除术后采用游离肩胛角皮瓣成功重建的患者。
肩胛角皮瓣的垂直定位可实现面部轮廓的重建,而其水平排列和微血管吻合则使硬腭的骨重建成为可能。
肩胛角皮瓣的多功能性、供区发病率低以及其形状与硬腭相似,使其成为整形重建的理想选择。骨质量对于种植体牙修复的适用性是一个有争议的讨论话题。根据奥凯等人的标准,肩胛角皮瓣是用于重建I级及以上上颌骨缺损的闭孔假体的替代方案。
