Application of Autologous Human Bone Marrow-Derived Mesenchymal Stem Cells in Distraction Osteogenesis for the Treatment of Bilateral Mandibular Hypoplasia

Distraction osteogenesis a surgical procedure conducted to improve craniofacial deformities. Compared with conventional operations, this technique has advantages such as the ability to lengthen the soft tissue and hard tissue. Therefore, this method is used to treat severe craniofacial abnormalities. The major disadvantage of distraction osteogenesis is the long treatment period. If the consolidation period is not sufficiently long after the distraction period, complications such as discontinuity or contraction of newly formed bone may occur. Recently, many researchers have attempted to develop methods for enhancing the ossification of newly formed bone, reducing shrinkage, and shortening the overall treatment period. The authors injected autologous bone marrow-derived mesenchymal stem cells during the consolidation phase after distraction osteogenesis surgery in a bilateral mandibular hypoplasia patient. Here, the authors report the treatment results, which were found to be favorable.
