Midface microvascular reconstruction after maxillary complex tumor resection: A retrospective study.

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.
