There are two primary locations in the mouth where frenula are identified; lip frenula and cheek frenula exist in the oral vesitibule and a lingual frenulum exists in the oral cavity proper. All frenula appear as a ruffle or fold of the mucous membrane.   Few disturbances originate in a morphological abnormality; almost all originate in a malpositioning of the adhesion, and present various symptoms. In cases where abnormal adhesion of the frenulum causes oral problems and treatment is needed, age seems to be an important factor. Ankyloglossia causes breastfeeding difficulties, articulation disorders, pronunciation disorders, and chewing and swallowing difficulties in the infant and young child. An abnormal cheek frenulum, which influences oral hygiene, can lead to gingivitis and periodontitis in young and middle-aged people. An abnormal cheek frenulum interferes with the stability of dentures when teeth are lost in old age; it makes it difficult to set them properly.  Because there seem to be many abnormalities in the lingual frenulum and the upper lip frenulum of infants and young children, we focused on assessment, diagnosis and surgical procedures (frenectomy) for both types of abnormality.

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.

It is beneficial for postdoctoral Japanese oral and maxillofacial surgery (OMFS) training to evaluate postdoctoral OMFS programs in other developed countries. Such studies should contribute to improving the quality of oral health in Japan. Currently there have been no research articles introduced for Japanese oral and maxillofacial surgeons that report on the postdoctoral OMFS training programs in the United States of America (USA). We therefore report the current status of oral and maxillofacial surgery training programs in the USA.Eleven topics are discussed. OMFS residency programs in the USA are speciality programs designed for oral and maxillofacial surgeons. Certification by the American Board of Oral and Maxillofacial Surgery is achieved after 4 to 6 years of training. A medical school curriculum is included in 46 of 102 OMFS residency programs. The average duration of the medical school curriculum was 28.4 months. Such curricula are designed to train OMFS residents who possess standard knowledge and techniques. The programs are strictly managed by a program director.
