The Japanese Society for Jaw Deformities performed a nationwide survey from 2006 to 2007 and the results were reported in 2008. In the last 10 years, new surgical procedures and medical devices have been developed and brought major changes to surgical orthodontic treatment. Accordingly, we need to assess the current status of surgical orthodontic treatment.A nationwide survey of surgical orthodontic treatment between April 2017 and March 2018 was carried out and 99 surgical facilities and 64 orthodontic facilities were enrolled in the survey. The number of patients who received orthognathic surgery was 3,405, about 69% of whom were diagnosed with mandibular protrusion. Before the surgery, 3D-simulation was performed for about 40% of patients at both surgical and orthodontic facilities. Computer-aided design and computer-aided manufacturing (CAD/CAM) wafers were used at 12.1% of surgical facilities and at 17.7% of orthodontic facilities. Sagittal split ramus osteotomy (SSRO) was performed in 2,768 patients (85.5%) and Le FortⅠosteotomy in 1,829 patients (56.5%). Blood loss during the surgery was reduced compared with that in the previous survey. Autologous blood transfusion tended to be performed in cases as necessary such as surgery for maxilla and anemia of the patient. Duration of intermaxillary fixation and hospital stay were also shortened. This survey revealed the current status of surgical orthodontic treatment in Japan in comparison with the previous survey.

Recently, the occurrence of methotrexate-associated lymphoproliferative disorders (MTX-LPD) in the oral area is reported one after another. We report a case of MTX-LPD of the maxillary gingiva associated with rheumatoid arthritis (RA). A 80-year-old man was referred to our clinic because of severe pain associated with a ulcer on the left side of the maxillary gingiva. On blood tests, soluble interleukin-2 receptor (sIL-2R) was high, and EBV infection was detected. The histopathological diagnosis was EBV-positive diffuse large B cell lymphoma (DLBCL). He had been receiving methotrexate for RA. We therefore requested discontinuation of methotrexate, and the lesion was decreased and symptoms disappeared. Examination after 21 months showed no evidence of recurrence.We reviewed reports documenting 17 cases of oral MTX-LPD in Japan. The age of onset was 40-84 years old, the male-to-female ratio was 4:13, and the methotrexate treatment period was 1-114 months. The affected sites were the maxillary and mandibular gingiva in 14 cases, the tongue in 1 case, and the mouth floor in 1 case. On histopathological classification, 14 cases were non-Hodgkin’s lymphoma, and 1 case was Hodgkin's lymphoma. As for the course of treatment, 11 cases had remission with cessation of methotrexate. Symptoms improved in 1-2 weeks, and lesions disappeared in 1-4 months.

舌癌治療ガイドラインの作成にあたり, 日本での舌扁平上皮癌治療の現状を把握するためアンケート調査を行い, 75回答の集計結果から本邦における舌扁平上皮癌治療の現状を報告した。<BR>有効回答の得られた75施設の過去10年間 (1995-2004) における総症例数は5, 906例であった。T, N分類ではT2が2, 700例 (45.7%) , N0が4, 367例 (73.9%) と最も多かった。<BR>手術療法では原発巣の切除範囲の適応基準, 頸部リンパ節転移に対する頸部郭清術および舌癌切除後の再建術における適応と術式については, 各施設とも適応基準がほぼ共通しており標準的な治療ガイドラインの作成は可能であるように思われた。<BR>一方, 原発巣や頸部の放射線や化学療法による, 術前・術後の補助療法の目的と適応が各施設それぞれに基準があり, その標準化はガイドライン作成の大きな問題点になると思われた。いずれにしても質の高いエビデンスを持つ治療法をガイドラインに盛り込む必要がある。
