Department of Oral and Maxillofacial Surgery 1

We have acted as clinically and academic pioneering facilities in the field of oral surgery under the guidance of Professor Mikihiko Kogo, who took over as the Professor after Professor Nagai (the first professor), Professor Miyazaki, and Professor Matsuya.
The Department of Oral Radiology separated in 1972, and the Division for Oral and Facial Disorders separated in 1985, and the name of our department was changed to Division of Pathogenesis and Control of Oral Disease (The First Department of Oral and Maxillofacial Surgery), along with Department of Dentistry's making to graduate school in 2000. The spirit of the department has not changed since the establishment, and has been succeeded by the present department members.

Research Activities

Research Activities

Since the establishment of the department, we have been eagerly researching about cleft lip and/or palate. Systematical research about articulation, expiratory flow, epidemiology, and development is at base of speech therapy to cleft palate patients. The elements of diagnosis technique were confirmed by observing velopharyngeal closure patterns using fiberscope. Physiological characteristics of innervations and muscle contractions of velar muscles were clarified by animal-tests. Now, the research is expanded to general oral function, not only about cleft lip and/or palate, and is focused on fundamental study about oral function and the brain stem, using experimental animals. Recently, the model of culture brain stem with organs to study mastication and respiratory movements is made, and is showing good performance in the neurophysiology field.
At the same time, there is a wide variety of experiments relevant to tumors, starting from the research on carcinogenesis of polyomavirus, experiments using established cell line of the polyomavirus, and research of organ malformation caused by rubella virus. There are also many researches related to differentiation of salivary glands and salivary gland tumors, metastasis formation mechanism of oral tumor, and bone metabolism.
In the recent years, the relationship between research institutes overseas is increasing, and enhancement in research activities is attempted in our division.
