To search for means of reducing ionizing radiation during treatment planning for transmandibular osteodistraction.Eleven patients (6 female, 5 male) underwent combined bimaxillary osteodistraction at a mean age of 18 Years. The following investigations were performed to determine symphyseal callus maturation: occlusal radiographs (O-RX) preoperatively, after the active phase of distraction (mean 27 days); ultrasound investigations (US) after the active and consolidation phase.US showed calcification foci at the end of the active phase, when O-RX failed to do so. Both US and O-RX detected callus immaturity after 2 Months of consolidation in 1 patient. Both detected bridging ossification one Month later.US can replace radiography in the diagnosis of callus maturation related to distractor removal.
