Abstract：
The study purpose is to review the surgical approach and evaluate the results in managing patients with advanced midface and maxillary complex tumors. The most common anatomical site of the primary tumor was the maxilla, sometimes with extension to the orbit and anterior fossa, parotid and middle ear or even the lip. Surgical resection included maxillectomy in the majority of cases, combined with orbital exenteration or orbitectomy and anterior fossa resection. Parotidectomy and mastoidectomy/core petrosectomy were also performed. Reconstruction was performed with radial forearm osteocutaneous free flap, latissimus dorsi myocutaneous flap with scapular bone flap, lengthening temporalis myoplasty, rectus abdominis free flap, anterolateral thigh flap, in combination with temporalis and vastus lateralis, as well as pectoralis major myocutaneous flap. A total of 36 midface tumor excisions were performed, followed by the appropriate reconstruction. The average follow-up period was 15 years. To date, 23 patients are disease free, while 6 patients presented disease recurrence and 7 patients died during the 15-year follow-up period. Surgical resection remains the gold standard for midface tumors management. When safely performed, combined with microvascular and dynamic face reconstruction, surgery can offer improvement in quality of life and prolong the overall survival.
摘要：
研究目的是回顾手术方法并评估治疗晚期中面和上颌复杂肿瘤患者的结果。原发性肿瘤最常见的解剖部位是上颌骨，有时延伸到眼眶和前窝，腮腺和中耳甚至嘴唇。在大多数情况下，手术切除包括上颌骨切除术，结合眼眶切除术或眼眶切除术和前窝切除术。还进行了腮腺切除术和乳突切除术/岩心切除术。前臂桡骨游离皮瓣重建，背阔肌肌皮瓣与肩胛骨皮瓣，延长颞肌成形术，腹直肌游离皮瓣，股前外侧皮瓣,结合颞肌和股外侧肌，以及胸大肌肌皮瓣。总共进行了36例中面肿瘤切除术，然后进行适当的重建。平均随访时间为15年。迄今为止,23名患者无疾病，在15年的随访期内，有6例患者出现疾病复发，7例患者死亡。手术切除仍然是中面肿瘤治疗的金标准。安全执行时，结合微血管和动态面部重建，手术可以改善患者的生活质量并延长总生存期.
