The aim of this study was to report on total mandibular subapical osteotomy (TMSO) to correct inferior alveolar retrusion, to describe its indications, the surgical technique and to analyse the aesthetic, occlusal changes and stability. Patients treated with TMSO from January 2004 to December 2014 were included and analysed retrospectively. Delaire's cephalometric analysis was performed before surgery and one year after surgery. Skeletal, occlusal and soft tissue changes were measured comparing lateral cephalographs before and after surgery. From January 2004 to December 2014, 8 patients were treated by TMSO. Six patients were analysed and presented a stable class I occlusion 3 years after surgery with an improvement of the labio-mental sulcus. Mean position of the dental apex of the inferior central incisor (ia) before surgery was -8.5mm corresponding on an inferior alveolar retrusion of -8.5mm. After surgery, mean ia position was -0.25mm showing an average of alveolar advancement of 8.25mm. Regarding the soft tissues movements, the mean labio-mental angle showed a variation from 84.7° to 120.3°, and the deepest point of the labio-mental sulcus (Mli) was advanced with a mean of 9.22mm corresponding to the bone movements. Total mandibular subapical osteotomy may be considered as a stable, safe and ideal procedure for patients having a class II deformity, due to a total inferior alveolar retrusion without mandibular retrognathism, improving labio-mental sulcus and chin shape.Show less >
