OBJECTIVE: To probe the possibility of trans-sutural distraction osteogenesis for correction of children midfacial hypoplasia.
METHODS: The trans-sutural distraction system of mid-facial skeleton consisted of the bone-borne traction hooks of titanium, the face-bow, and the elastic loops. Nine children with midfacial hypoplasia were treated at their 6 - 12 years of age. No osteotomy was made in them. Bone holes were drilled with a dental bur at each side of the lateral-inferior rim of the aperture, or at the anterior part of the hard palate. The traction device was hatched to the holes through the nostrils. Protraction began 3 days postoperatively, with the forces adjusted dependently upon the rate of progress. When the skeleton reached to the planed position, it was retained with a minor force for 8 weeks.
RESULTS: The mid-facial skeleton of the nine children showed a balanced advancement. Their facial profile and cross-bite were corrected satisfactory.
CONCLUSIONS: Patients with severe mid-facial hypoplasia could be corrected ideally by the new technique, with minor trauma, easy manipulation. The design of protraction system was reasonable.
