Abstract
Objective: To evaluate the effect of internal distraction osteogenes is in treatment of difficult and complicated dento-gnatho-facial deformities, and to study the advantages, disadvantages, and indications of different distractio n modalities. Methods: Those cases hard to be treated with conve ntional proced ures were selected for study. Seven kinds of dento-gnatho-facial deformities ( 88 cases) were treated with the intraoral distraction osteogenesis technique. They included: 9 cases of severe maxillary hypoplasia secondary to cleft palate, 11 cases of hemifacial microsomia, l7 cases of severe micrognathia accompanie d with obstructive sleep apnea syndrome, l4 cases of TMJ ankylosis, 8 cases of r econstruction of jaw defects, 17 cases of alveolar-bone defect treated by verti c al distraction, and 12 cases with upper and lower dental arch constriction for expansion. The youngest patient was 4.5 years of age, and the oldest 54 year s, with a mean of 22.5 years. The Germany Medicon Co. and Martin Co. produced distr actors were used in 22 cases. In other cases, 7 types of distractors designed an d cooperatively developed by the first author were used. The mode of osteotomy, t he selection and placement of distractor, and the modality of distraction depend ed on the types of deformity, the degree of severity, and the sites of the jaws. Results: The distraction distances in maxilla were 7-l5 mm, and 1 2-50 mm in man dible. 3 cases had local chronic infection leading to resorption of a part of th e new bone; other 3 cases had fracture of the mandibular inferior border and the troubles of the distractor; they had had addi tional operations to complete the distraction. The other cases went on with dist racti on osteogenesis smoothly obtaining good bone formation, their dento-gnatho-fac ia l deformities were corrected satisfactorily. Conclusion: The intraor al distract ion osteogenesis for jaws provides a new and effective means for those difficult and complicated dento-gnatho- facial deformities which are hard to be treated b y conventional measures. This is a technique of wide application value and worth y to be spread.
