The Department of Oral and Maxillofacial Surgery, Peking University School of Stomatology, developed from the dental unit, Medical College Peking University, which was founded in 1941. As one of the earliest departments of oral and maxillofacial surgery in China, it was formally established in 1955. In 1982, the department was appointed as one of the first Doctorate Program in China by the Academic Degree Committee of the State Council. The first medical PhD degree in China was awarded in this department, which was selected among the first key disciplines being qualified for the "National 211 Project" . Currently it is a designated National Key Discipline, National Continuing Education Base, AOCMF Fellowship Center and IAOMS Oral and Maxillofacial Oncology and Reconstructive Surgery Training Center.

The Department of Oral and Maxillofacial Surgery is composed of one outpatient clinic, one laser and cosmetic clinic, five wards for in-patients, one resuscitation room and one laboratory. The department is equipped with 29 dental units and 171 patient beds, providing medical services to approximately more than 100,000 out-patients; more than 7,000 in-patients are operated under general anesthesia per year.

Currently the department has many domestic and international well-known experts and professors. Among the 227 staff members, there are 64 doctors and 157 nurses. There are 28 professors/chief physicians and 19 associate professors/chief physicians. 10 doctoral supervisors and 9 master's supervisors are listed in the postgraduate program. More than 87% of the doctors in the department hold doctoral degrees. The department enrolls more than 40 postgraduate students, 50 visiting doctors and 15 International Fellows per year.

During the last three years, 55 research grants with an overall amount of 38 million RMB from National Natural Science Foundation, Ministry of Education and Ministry of Science and Technology of China were granted. 204 papers were published in international and national peer reviewed journals.

The diseases involved in lips, oral cavity (teeth, gingival and alveolar bone, buccal, tongue, mouth floor, palate, oropharyngeal), face (maxilla, mandible, orbital, zygoma), cranial base, neck, salivary gland may be treated in the department of oral and maxillofacial surgery. These diseases are listed as follows:

1. Alveolar surgery, i.e. wisdom teeth extraction, alveoloplasty.

2. Oral and facial implantation.

3. Head and neck tumors and tumor-like disease.

4. Oral and maxillofacial trauma.

5. Congenital developmental deformities such as cleft lip and palate.

6. Orthognathic surgery and distraction for acquired cranio-maxillofacial deformities.

7. Salivary gland diseases.

8. Functional reconstruction of defects of the head and neck.

9. Brachytherapy for malignant tumors in the oral and maxillofacial areas.

10. Infectious diseases.

11. Organ transplantation, submandibular gland transfer for severe keratoconjunctivitis sicca.

12. Facial nerve diseases such as trigeminal neuralgia.

13. Oral and maxillofacial vascular malformations.

Clinical specialties and research topics include: digital techniques and surgical navigation, dental extraction under ECG monitoring, sedation management for oral surgery, radiofrequency treatment of trigeminal neuralgia, brachytherapy for malignant tumors in the oral and maxillofacial areas, surgical treatment for tumors of skull base, submandibular gland transfer for severe keratoconjunctivitis sicca, functional surgeries of salivary gland tumors, multidisciplinary management of trauma and related deformities, orthognathic surgery and distraction for cranio-maxillofacial deformities, comprehensive treatment of oral and maxillofacial vascular malformations, functional reconstruction of head and neck defects, TMJ ankylosis and surgical management, sequencing treatment of cleft lip and palate, translational medicine, and tissue regeneration.
