Ninety-one patients with locally-expanded maxillary malignancies treated with comprehensive therapy had an average age of 44.2 years; 66 cases were epithelial-derived, and 25 cases were non-epithelial; 13 cases were in stage III, 23 cases were in stage IV, and 55 cases could not be staged. Tumor origin: 47 cases (51.6%) of maxillary sinus, 18 cases of ethmoid sinuses, 12 cases of nasal cavity, 14 cases of alveolar ridge and hard palate; 40 cases of excision of orbital wall and orbital ridge, preserved eyeballs, and fistula contents Twenty-five patients underwent patella resection in 24 cases, 43 cases of facial soft tissue resection, 5 cases of anterior cranial fossa resection, and 17 cases of contralateral anatomical resection. (The total number was more than the number of patients because one patient had several resections.) Among 91 cases, there were 47 (66) relapsed patients (38 cases were integrated for the first time)
