Oral Maxillofacial Surgery

  • Head of division
    Kazuo Ryoke
We deal with not only "surgical diseases" but all the oral and maxillofacial surgeons; in other words, we are "Oral and Maxillofacial Surgery" Division.  

In addition to periodontal diseases, we treat a wide variety of diseases such as malignant tumor, congenital anomaly such as harelip and cleft palate, external injury, jaw deformity, temporomandibular joint disease, oral mucosal disease, salivary gland disease, and halitosis. For oral cancer including tongue cancer, we often use a non-surgical approach, namely super-selective intra-arterial chemotherapy to conserve the function. In our division, 60% of tongue cancers are cured with this method, conserving the organ and function.

Field of expertise

  • Oral cancer

We are one of the very few facilities in the San-in area and also in Japan that provides consistent treatment for patients with harelip/cleft palate, namely surgical treatment, orthodontics by an orthodontist, and logotherapy by a speech-language pathologist.

For the treatment of maxillofacial defects, we try to recover esthetic quality by implant prosthesis and epithesis.
