Application of ultrasound in callus distraction of the hypoplastic mandible: an additional method for the follow-up

Mandibular callus distraction was performed on 14 patients. In addition to established radiological methods, sonography was performed to monitor the c linical progress. Ultrasound shows a precise picture of all interesting ite ms in distraction treatment. Although the value of radiographs is not obsol ete completely, sonography was found to be a meaningful supplement in the c linical monitoring of callus distraction. Furthermore the method is capable of early recognition of complications and it can reduce X-ray exposure.
