Treatment: Comprehensive treatment mainly based on surgery.1. Treatment of primary foci The treatment of palate cancer is mainly based on surgery. Pinyamycin chemotherapy can be used, and radiotherapy or radioactive particle implantation in our hospital can be added. In general, surgery should be performed to remove the lesion including the palate bone. For larger lesions, a subtotal maxillary resection should be performed. If the maxillary sinus has been invaded, total maxillectomy should be performed. After surgical resection of the primary lesion of palatal cancer, restoration of the defect and teeth should be done with prosthesis (pseudo-replica), and temporal muscle flap transfer repair is optional for some cases. The rate of cervical lymphatic metastasis of palatal cancer is about 40%, and bilateral cervical metastasis often occurs in advanced cases. In addition to therapeutic treatment, bilateral selective cervical lymphatic dissection can also be considered, and the operation can be performed with one functional or bilateral functional cervical lymphatic dissection. Prognosis: The prognosis of squamous carcinoma of the palate is poor, and the 5-year survival rate is 66% according to statistics. Those with advanced stage and cervical lymphatic metastasis have poorer prognosis, and the 5-year survival rate is only 25%. Early detection and early standardized treatment are the main reasons to achieve better results. Prevention: 1, often self-examine the oral mucosa for lesions. 2, do quit smoking, alcohol, reduce the stimulation of the mucosa. 3, early extraction or adjustment of the residual roots and crowns or crooked teeth, to reduce the stimulation of the adjacent mucosa. 4. Ask the specialist to examine and treat the mucosal lesions as early as possible. To achieve the purpose of early detection and treatment.
