在Le Fort I型截骨术中，为了准确地将上颌骨定位在上级或后部，需要去除腭降动脉（DPA）和上颌骨结节周围的骨。因为Le Fort I截骨术中最常见的出血部位是后上颌骨，这种骨切除术为外科医生提供了DPA损伤的手术挫折。当在去骨和结扎过程中损伤DPA时，可能会发生上颌骨的无菌性坏死。因此，我们报告了在Le Fort I截骨术中使用简单的手工牵开器来保护DPA。
For accurate superior or posterior repositioning of the maxilla in Le Fort I osteotomy, bone removal around the descending palatine artery (DPA) and maxillary tuberosity is required. Because the most common site of hemorrhage in the Le Fort I osteotomy is the posterior maxilla, this bone removal provides surgeons to surgical frustration of DPA injury. When the DPA is injured during the bone removal and the ligation is performed, aseptic necrosis of the maxilla may occur. Therefore, we report the use of a simple handmade retractor to protect the DPA in Le Fort I osteotomy.
