Abstract：
Reconstruction of large craniofacial defect after plexiform neurofibroma excision poses a continuous challenge for plastic surgeons, on account of characteristics of plexiform neurofibroma and patients\' aesthetic requirements. Skin graft or free flap is hard to obtain satisfactory results or may pose technical challenges. In an attempt to provide the coverage with \'like tissue\', we chose local tissue expansion technique. The expansion period was about an average of 3.4 months. We performed 19 expanded flaps located in the head, face, neck, forearm and superclavical regions to reconstruct the craniofacial defect and achieved satisfactory results. Preoperative endovascular embolism in some cases and several intraoperative hemostatic methods for all cases were undertaken to control the perioperative bleeding. For patients who request aesthetic results and are allowed two-staged operations, our method is viable.
摘要：
丛状神经纤维瘤切除术后大型颅面缺损的重建对整形外科医生提出了持续的挑战，考虑到丛状神经纤维瘤的特点和患者的美学要求。植皮或游离皮瓣很难获得满意的效果或可能构成技术挑战。为了提供带有“类似组织”的覆盖范围，我们选择了局部组织扩张技术。扩张期约为平均3.4个月。我们在头部做了19个扩张皮瓣，脸,脖子,前臂和锁骨上区重建颅面缺损，取得了满意的效果。在某些情况下采取术前血管内栓塞，并在所有情况下采取几种术中止血方法来控制围手术期出血。对于要求美学结果并允许进行两阶段手术的患者，我们的方法是可行的。
