“双一流”建设的中心内容是学科建设。该文通过回顾上海交通大学医学院附属第九人民医院口腔颌面外科的学科发展、取得的成绩，以及学科发展过程中“志存高远”和“改革开放”的2条指导思想，总结出4条学科建设的成功经验：人才培养，梯队建设为先；人才分流，增加溢出效应；倡导学科交叉与交叉学科；推行体制改革与学科创新。此外，该文还对学科建设的未来提出4点建议：宜将“中国式”的口腔颌面外科更名为“中国特色”的口腔颌面外科；以创新为先导，以科研为灵魂；以自然科学与人文科学整合为切入点，以“整合”为指导，培养复合型人才；进一步加强和重视医学中的人文教育。

The core of “Double First-Class” initiative is discipline construction. Through reviewing the development and the achievements of the Department of Oral and Maxillofacial Surgery, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine, and two guiding thoughts, i.e., “high ambition” and “reform and opening up”, the following four experiences are summarized: talent cultivation and echelon construction, talent diversion to increase spillover effect, advocating interdisciplinarity and transdisciplinarity, and introducing system reform and discipline innovation. Furthermore, four suggestions for the future are proposed: the oral and maxillofacial surgery of “Chinese style” should be changed to “Chinese characteristics”; innovation should be taken as the forerunner and scientific research as the soul; with the integration of natural science and humanities as the breakthrough point and the guidance of integration, the interdisciplinary talents should be trained; humanistic education in medicine should be further enhanced.
