Distraction osteogenesis: Our experience of six patients
International Journal of Medical and Dental Case Reports
Distraction osteogenesis (DO) is an established therapeutic technique for new bone formation during significant lengthening of the craniofacial skeleton without the need for bone grafting or orthognathic surgery. Hemifacial microsomia, mandibular retrognathia, posttraumatic or resection deformities of the mandible and multiple syndromes associated with maxillo-mandibular malformations have been successfully corrected using this technique. Materials and Methods: We report six cases who presented
... with a varied range of symptoms due to congenital and acquired deformities of the maxilla and mandible. DO was used for the correction of each of these deformities. Vertical alveolar DO was performed in two patients while two required mandibular distraction. Surgically assisted rapid maxillary expansion (SARME) was used in one patient. Both mandibular distraction and SARME was performed in the other patient. Results: In all cases, the planned lengthening was achieved without any immediate or delayed complications. Conclusion: Thus, DO consistently produce a measurable increase in the bone length with better functional and esthetic outcomes.
