This report describes the development of a new technique for harvesting facial allograft for facial transplantation. The coronal-posterior surgical approach for facial/scalp flap harvesting from donor cadavers has been developed to allow extended length to the neurovascular bundles utilized in facial composite allograft transplantation. Cadaveric anatomic dissections were performed to harvest facial/scalp flaps via a posterior-coronal approach. Supraorbital and infraorbital neurovascular bundle lengths were extended by osteotomy of the cranial/orbital bone. The mental nerve lengths were extended into the inferior alveolar neurovascular bundle utilizing a sagittal split ramus osteotomy. This surgical approach extends the length of these craniofacial nerves for future neurorrhaphy. The mean length of the supraorbital, infraorbital, and mental nerves was 3.52 +/- 0.31 cm, 4.65 +/- 0.20 cm, 5.6 +/- 0.14 cm, respectively. Based on anatomical dissection in this cadaver study, the authors introduce a new technique for facial/scalp flap harvesting that extends the neurovascular bundles of sensory nerves of the anterior craniofacial skeleton.
本报告描述了一种用于获取面部移植同种异体面部组织的新技术的开发。已开发出从供体尸体获取面部/头皮皮瓣的冠状-后入路手术方法，以延长面部复合移植同种异体组织中使用的神经血管束的长度。通过尸体解剖，采用后冠状入路获取面部/头皮皮瓣。通过颅骨/眶骨截骨术延长眶上和眶下神经血管束的长度。利用矢状劈开下颌支截骨术将颏神经长度延长至下牙槽神经血管束。这种手术方法延长了这些颅面神经的长度，以便将来进行神经缝合。眶上神经、眶下神经和颏神经的平均长度分别为3.52±0.31厘米、4.65±0.20厘米、5.6±0.14厘米。基于本尸体研究中的解剖，作者介绍了一种获取面部/头皮皮瓣的新技术，该技术可延长前颅面骨骼感觉神经的神经血管束。
