Reconstruction of critical-sized defects of composite facial units is a challenging one. This is amplified when facial hair-bearing areas are included. A case of reconstruction of multiple midfacial defects is presented. Initially, defective jaws were addressed. Later, appropriate modification of existing extended paramedical forehead flap to sequentially reconstruct defective lip, moustache, and parts of alae are described. The flap design was such that hair-bearing areas were used to reconstruct moustache while the nasal alar defect was reconstructed using the non-hair-beating forehead skin. Finally, dental implants were also placed. The technique was reliable, giving minimal donor site deformity but with maximum result. However, it is a multi-stage procedure. The paper also describes the challenges of midfacial unit reconstruction as handled in this case.
复合面部单元临界尺寸缺损的重建是一项具有挑战性的工作。当涉及到有毛发的面部区域时,这一挑战会进一步加剧。本文介绍了一例多发性面中部缺损的重建病例。首先处理了有缺陷的颌骨。随后,描述了如何对现有的扩展辅助前额皮瓣进行适当修改,以依次重建缺损的唇部、胡须和鼻翼部分。皮瓣设计使得有毛发的区域用于重建胡须,而鼻翼缺损则使用无毛的前额皮肤进行重建。最后,还植入了牙种植体。该技术可靠,供区畸形最小但效果最佳。然而,这是一个多阶段的手术。本文还描述了该病例中处理面中部单元重建所面临的挑战。
