Mandibular reconstruction in osteoradionecrosis or salvage surgery can often be complicated by the lack of suitable recipient vessels in the ipsilateral neck and the associated requirement for significant extraoral skin reconstruction. The scapula tip with its long vascular pedicle and option of a chimeric soft tissue component offers a versatile reconstructive solution in such cases. This article reports four consecutive cases of mandibular reconstruction with poor ipsilateral vascular options and additional soft tissue requirements in which the scapula tip was justified and preferred. The blood supply to the lateral scapula through the circumflex scapular system is well established in the literature and this would be the preferred reconstruction in class I mandibular defects associated with a significant soft tissue requirement. The scapula tip would suit cases where the ipsilateral recipient vessels are compromised, and so justify the potential for mandibular reconstruction with inferior bone stock.
放射性骨坏死或挽救性手术中的下颌骨重建常常因同侧颈部缺乏合适的受区血管以及需要进行大面积口腔外皮肤重建而变得复杂。带有长血管蒂的肩胛尖以及可选择的嵌合软组织成分,为这类病例提供了一种多功能的重建解决方案。本文报告了连续4例同侧血管条件不佳且有额外软组织需求的下颌骨重建病例,在这些病例中,肩胛尖是合理且首选的重建方式。文献中已充分证实通过旋肩胛系统为肩胛外侧供血,这将是伴有大量软组织需求的I类下颌骨缺损的首选重建方式。肩胛尖适用于同侧受区血管受损的病例,因此对于骨量不足的下颌骨重建具有合理性。
