PURPOSE: This report presents the results of distraction osteogenesis using an extra oral device in 28 patients with different grade of vertical mandibular ramus hypoplasia.
MATERIAL AND METHOD: 28 patients (aged 2 to 15 years) with hemifacial microsomia underwent unilateral lengthening of the ascending ramus using unidirectional extraoral devices (Molina distractor). 3D-CT and cephalometric radiographs were analysed to determine the placement of the mandibular osteotomy and select the appropriate placement of the distraction device.
RESULT: On the basis of one-year follow-up we can conclude that excellent, stable and functional mandibular lengthening was achieved with external distraction osteogenesis with minimal complications in all our patients. Coordinated growth between maxillary and mandibular arches with stable occlusion is observed.
CONCLUSION: Mandibular distraction osteogenesis has proved to be an excellent technique for the treatment of mandibular deficiency. Careful and comprehensive planning of treatment, coupled with control of the distraction vector can bring about predictable results with minimal morbidity. Nevertheless. It is our conclusion that good and effective orthodontics within the period of consolidation is the key to achieve satisfactory stability results.
