Osteosarcoma is one of the rare malignant tumors in the maxillofacial region. Synthetic sequential therapy including radical resection and adjuvant radio-chemotherapy is the most effective currently. Chemotherapy is an important part in synthetic sequential therapy. In the existing chemotherapy regimens, traditional chemotherapy such as MAP(methotrexate, adriacin, cisplatin) plays a key role in the treatment of osteosarcoma in oral maxillofacial-head and neck region. In addition, some other regimens such as neoadjuvant chemotherapy, electrochemical therapy are also proposed in recent years, but their effectiveness remains to be investigated. Chemotherapy has a significant effect on improving the prognosis of osteosarcoma. With the gradual development of the cognition of osteosarcoma molecular biology in recent years, it has become a new trend to study the chemical drugs for tumor cells in the level of molecular biology. This paper reviews the application of chemotherapy in the treatment of osteosarcoma in oral and maxillofacial-head and neck region.%骨肉瘤是颌面头颈部较为罕见的恶性肿瘤之一，包括局部切除手术及辅助放化学治疗在内的综合序列治疗是现阶段最有效的治疗方法。化学治疗是综合序列治疗的重要组成部分。在目前已有的化学治疗方案中，甲氨蝶呤、阿霉素和顺铂（MAP）等经典化学治疗方案在口腔颌面头颈部骨肉瘤的治疗中有重要的作用；此外，新辅助化学治疗和电化学疗法等方案也在近年诞生，然而其临床应用价值尚待考证。随着近年来对骨肉瘤分子生物学认知的逐步深入，在分子生物学水平上探讨针对肿瘤细胞的化学药物成为新的进展趋势。本文就化学治疗在颌面头颈部骨肉瘤治疗中应用的研究进展作一综述。
