Expansion Technique for Reconstruction of Craniofacial Defect after Plexiform Neurofibroma Excision.

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.
