    Regarding the open surgery of temporomandibular joint mobilization for the removal of adhesive pseudwalls assisted by arthroscopy, this summary explained the surgical approach by Al-Kayat and Bramley, anatomically important points to remember, indications and treatment results, and procedures and the importance of postoperative rehabilitation.
    This introduced the diagnostic procedures and treatment algorithm for temporomandibular joint disorders (types IIIb and IV) patients with severe mouth-opening disturbance (mouth-opening distance was less than 30 mm) in the Second Department of Oral and Maxillofacial Surgery, Osaka DentalUniversity. Furthermore, regarding intractable cases whose disease period was more than 6 months and adhesion lesions in the temporomandibular joint were suspected, we evaluated the clinical significance of the open surgery of temporomandibular joint mobilization for the removal of adhesive pseudwalls assisted by arthroscopy as a salvage operation.

    The Japanese Society of Oral and Maxillofacial Surgeons, the Japanese Academy of Maxillofacial Implants, the Japanese Society of Oral Implantology, and the Japanese Society of Oral Medicine performed a cross-sectional study examining the relation between tobacco smoking and oral diseases among Japanese, conducted using a questionnaire survey. Material and methods: Among 503 related designated training facilities, information on the clinical characteristics of smoking, age, sex, alcohol consumption, and diabetes were collected from patients with oral squamous cell carcinoma (OSCC) , oral potentially malignant disorders (OPMD), necrotizing ulcerative gingivitis (NUG), dry socket, bisphosphonate-related osteonecrosis of the jaw (BRONJ), and dental implants during a 1-year period from January 1, 2012 through December 31, 2012. Smoking rates were calculated for each disease, and the relations between smoking and other demographic features were investigated in subgroup analyses. Results: We collected 260 (51.7%) survey sheets from the 503 target facilities that were sent questionnaires. Among these, 246 met the study criteria. Data on smoking habits were unavailable for approximately 20% to 40% percent of the target diseases. For dental implants (n=1,933), the rate of current smokers in the implant failure group (24.4%, failure within 1 year) was higher than that in the non-failure group (12.8%). The odds ratio for implant failure was 2.20 (95% confidence interval: 1.34-3.63) for current smokers. The rates of current smokers among patients with OSCC (n=3,223)/OPMD (n=1,224) were respectively 31.9%/41.0% in males and 8.8%/17.3% in females, and the rate of past smokers was higher in OSCC. The rates of smoking were highest for OSCC and OPMD arising in the floor of the mouth among all primary sites. The rates of current smokers in NUG (n=59), dry socket (n=629), and BRONJ (n=830) for males and females were 36.4%/ 2.8%, 36.1%/ 11.6%, and 13.2%/ 5.2%, respectively. Conclusion: Our results suggest that smoking is associated with OSCC and OPMD in the floor of the mouth and is significantly related to implant failure. Based on these findings, further studies of interventions for the prevention and cessation of smoking are expected to control oral diseases.

    Metastatic tumors of the oral region are rare, accounting for about 1.6% of all malignant tumors in the oral cavity. In this article, we report a case of pulmonary pleomorphic carcinoma that metastasized to the mandibular gingiva. A 66-year-old man was referred to our department to determine the cause of fever. Although the patient had a medical history of pulmonary pleomorphic carcinoma, the lung cancer was controlled. He presented with marked bleeding from a left mandibular gingival swelling at the first visit. The tumor marker was in the normal range, but he had a markedly elevated white-cell count and C-reactive protein levels. We diagnosed his condition at the initial visit as the acute phase of periodontitis. A biopsy was performed because the gingival tumor was suspected to be a metastasis from lung cancer. The gingival tumor was histopathologically similar to the pulmonary lesion. Therefore, the final diagnosis was metastasis of pulmonary pleomorphic carcinoma to the left mandibular gingival mucosa. Surgical treatment was not performed because of other distant metastatic lesions found on systemic examination. The patient died 3 months later.
    The outcomes of lung cancer with gingival metastasis are very poor. Early detection and appropriate treatment are necessary. We described a rarely reported case of gingival metastasis from pulmonary pleomorphic carcinoma.

    Solitary plasmacytoma of bone is extremely rare in the jaw and most frequently arises in vertebrae and the skull. We report a case of solitary plasmacytoma arising in the mandible. A 67-year-old woman was referred to our hospital because of a slowly developing swelling in the right cheek. Intraoral examination disclosed a diffuse swelling in the right retromolar region. The patient did not have any pain or numbness. Panoramic radiography and computed tomography showed an osteolytic lesion measuring 20 × 15 mm in the right mandibular ramus. Laboratory analysis of the patient's blood and urine did not indicate any remarkable data. An incisional biopsy was performed with the patient under general anesthesia. The histopathological examination confirmed the diagnosis of plasmacytoma, predominantly IgA- λ type. Because there were no abnormal findings on bone marrow aspiration, the patient received local radiotherapy with a total dose of 50 Gy (in daily fractions of 2 Gy), and the tumor completely regressed. Seven years after radiotherapy, the patient is still alive without signs of recurrence or progression to multiple myeloma.

    We report a case of cyst of the papilla palatina. A 70-year-old woman was referred to our department to receive consultation for a swelling of the anterior hard palate. On intraoral examination, we confirmed a defined swelling, measuring approximately 13 × 10 mm, in the soft tissue of the palatine papilla. A computed tomographic scan showed pressure-induced enlargement of the incisive fossa. We removed a cyst with the patient under general anesthesia. Histopathological examinations revealed inflammatory cell infiltration of the cyst wall, which was lined by stratified squamous epithelium, ciliated columnar epithelium, and simple cuboidal epithelium. We diagnosed a cyst of the papilla palatina based on clinical, radiological, and histopathological findings. After operation, there has been no sign of recurrence.
