Greetings
Our department treats benign and malignant tumors (cancer) and cysts of the oral cavity and jaw, jaw deformities, oral and maxillofacial trauma, infections extending around the jaw, oral mucosal diseases, salivary gland diseases, temporomandibular joint disorders, and tooth extractions that are difficult to perform at other hospitals. We also provide oral function management for patients undergoing treatment under general anesthesia, with the aim of reducing perioperative complications. Our experienced staff, including board-certified oral surgeons, strive to provide advanced and medically safe care.
Most of our patients are referred to us from nearby medical institutions. We sometimes prioritize patients with urgent conditions, which may result in waiting times, but we strive to provide a comprehensive medical care system.

Treatment details
In oral surgery, we treat diseases affecting the oral cavity, jaw, and surrounding areas, providing both surgical and medical care. We practice safe, team-based medical care, collaborating with various departments such as plastic surgery medicine, general surgery, Otolaryngology, Head and Neck Surgery Department of Radiation Therapy Department of Anesthesiology, radiation oncology, pediatrics, Department of Rehabilitation, and rehabilitation as needed. In most cases, we ask referring dentists to continue pre- and post-operative procedures, as well as general dental treatments such as prosthetics and restorative dentistry. We also ask medical doctors to manage underlying medical conditions. In cooperation with local dental and medical associations, we strive to fulfill our role as an acute care hospital based on regional collaboration and as a specialized hospital providing advanced medical care.
Main target diseases
We treat oral and surrounding conditions such as tooth extraction, inflammation, jaw, facial, and oral trauma, temporomandibular joint disorders, cystic diseases, jaw deformities, benign tumors, and malignant tumors. We also treat oral diseases that occur in conjunction with systemic diseases, such as oral mucositis caused by drug therapy, and osteonecrosis of the jaw caused by bisphosphonate drugs used to treat osteoporosis and bone metastases from cancer.
Main medical achievements
The oral surgery department sees over 8,000 new patients annually, approximately 70% of whom are referred by dentists or other physicians. Outpatient services include tooth extraction, dental infections, trauma, temporomandibular joint disorders, oral mucosal diseases, neurological disorders, oral symptoms associated with systemic diseases, and postoperative follow-up. Inpatient care includes approximately 540 patients annually, of which over 400 undergo general anesthesia. The most common general anesthesia surgeries are for malignant tumors, followed by jaw deformity surgery, cyst and benign tumor surgery, trauma surgery, and infection and inflammation surgery. For patients undergoing minor surgeries such as tooth extraction, we also offer short-term hospitalization with intravenous sedation to alleviate anxiety and discomfort.
Our department is one of the leading oral cancer treatment facilities in Japan. We develop treatment plans after obtaining thorough informed consent from patients and their families. We perform approximately 120 oral cancer-related surgeries annually, one-third of which are immediate reconstructive surgeries using free flaps. We strive to provide treatment that balances function preservation and radical cure, taking into account occlusion, mastication, swallowing, articulation, facial appearance, and lifestyle. We collaborate with related departments to provide evidence-based, multidisciplinary medical care.
