OKAYAMA UNIVERSITY HOSPITAL

Message from the Director of the Department

Scope of Target Diseases

• Surgical treatment of teeth and periodontal tissues (oral mucosa and alveolar bone): tooth extraction with higher difficulty, tooth extraction in medically compromised patients, pre-prosthetic surgery, and fenestration and extrusion of delayed eruption.
• Inflammation: severe infection in the oral and maxillofacial region
• Oral tumor: benign and malignant tumors (oral cancer) in the oral region
• Jaw deformity: abnormalities of the jaw resulting in malocclusion
• Cyst: cysts in the jaw and oral soft tissues
• Trauma: bone fracture of the jaw, dental injury, oral soft tissue injury and facial soft tissue injury
• Salivary gland disease: sialolithiasis, mucocele, and salivary gland tumor
• Dental implant: difficult cases with atrophy of the jaw and maxillofacial prosthesis with dental implant
• Oral mucosal disease and xerostomia (dry mouth): leukoplakia, lichen planus, and intractable stomatitis
• Temporomandibular joint diseases: temporomandibular joint dislocation and temporomandibular joint disorder
• Drug-induced (such as therapeutic drugs for osteoporosis) osteonecrosis of the jaw and oral disease

Features and Description of Medical Care

• Oral mucosal disease and oral tumor
  We provide diagnosis and treatment for oral mucosal lesions, precancerous lesions, odontogenic tumor, and oral cancer.
  We produce a treatment policy with the aim of improving treatment outcomes through multidisciplinary treatment.
  Speech disorder, masticatory disturbance, dysphagia, and aesthetic problems after initial treatment are treated by reconstructive surgery, maxillofacial prosthesis, and therapy for dysphagia in close collaboration with the supporting team.
• We reconstruct the jawbone with a custom made titanium mesh tray and autogenous iliac cancellous bone. Then we reconstruct the occlusion using the dental implant.
• Superselective intra-arterial infusion chemoradiotherapy for oral cancer
  We are striving to preserve organs as much as possible and to perform tumor resection minimally through a combination of radiotherapy and special chemotherapy. Anticancer drugs are injected super-selectively into the targeted cancer through a catheter.
• Jaw deformity
  We perform surgical correction with an orthodontist. Our department has one of the largest operation volumes in western Japan. Severe jaw deformity is treated by distraction osteogenesis, which is a method of gradual jaw extension.
• Habitual temporomandibular luxation
  We perform autologous blood injection therapy and surgical treatment.
• Oral and maxillofacial implants
  Implantation combined with bone regeneration by bone graft and bone extension is performed for difficult cases such as severe bone defects or jaw atrophy.
