Labial tissue defects that extend beyond the anatomic boundary of the labial region confront us with two distinct reconstructive problems. When the extension is centrifugal towards the periphery, the tissue loss is essentially tegumentary. The reconstructive aim in this case is not only to restore tissues of the perilabial areas with the best possible morphologic and functional harmony but also to place the reconstructed lip harmoniously and in good relation to these structures. In the case of posterior extension of tissue losses towards the jaws, it is mandatory to reconstruct the underlying bony and eventually alveolo-dental architecture prior to the lip reconstruction. The reconstruction strategy is emphasised by two cases of complex ballistic injury.
超出唇部区域解剖边界的唇部组织缺损给我们带来了两个截然不同的重建问题。当缺损呈离心状向周边扩展时，组织缺失本质上是皮肤性的。在这种情况下，重建的目标不仅是以尽可能好的形态和功能协调性恢复唇周区域的组织，还要使重建后的唇部与这些结构和谐且位置良好。在组织缺损向后延伸至颌骨的情况下，在进行唇部重建之前必须先重建下方的骨质结构以及最终的牙槽-牙齿结构。两个复杂弹道伤病例突出了重建策略。
