Oral(oropharyngeal)cancer is a type of malignant tumors of the head and neck with the highest incidence.Many patients have been clinically advanced,and most of them need to be treated by surgery combined with radiotherapy and chemotherapy.Many patients with oral(oropharyngeal)cancer will have local recurrence or metastasis after the first surgical or chemoradiotherapy,and the second treatment is more difficult with the poor prognosis.How to effectively treat these patients with advanced or recurrent oral(oropharyngeal)cancer has become the focus of clinical attention.However,there is no basis to follow about how to carry out therapeutic surgical treatment,and non-standard diagnosis and treatment are also common.Therefore,we formulated this consensus in the fields of definition,indications,perioperative evaluation,surgical classification,adjuvant therapy,functional rehabilitation and other fields of advanced or recurrent oral(oropharyn-geal)cancer,based on evidence-based medical evidence and national maxillofacial head and neck surgery expert sugges-tion,for reference by oral and maxillofacial,and head & neck surgeons across the country.
