Zygomatic aplasia in patients with Treacher Collins syndrome requires reconstruction with autogenous bone grafts. Serial bone grafting may be required if optimal malar projection is not achieved with the initial procedure. This report demonstrates the use of distraction osteogenesis in repositioning a previously bone-grafted zygoma in an adolescent patient with Treacher Collins syndrome, thus avoiding the need for repeat bone graft harvest. The limitations of this technique include difficulty in achieving the desired vector of distraction and the potential of graft devitalization. Nevertheless, the case report illustrates the versatility of distraction osteogenesis in skeletal augmentation/remodeling.

CBCT-Based Analysis of Factors Influencing the Quality of New Bone Formation Following Mandibular Distraction Osteogenesis in Children With Pierre Robin Sequence.
J Craniofac Surg
January 2025
Department of Oral and Maxillofacial Surgery, Guangzhou Medical University Affiliated Women and Children's Medical Center, Guangzhou, China.
The aim of this study was to explore the factors influencing the quality of new bone formation after distraction osteogenesis in children with Pierre Robin sequence (PRS). Using cone-beam computed tomography (CBCT), bone density relative grayscale values of the region of new bone formation before and 3 to 4 months after mandibular distraction osteogenesis (MDO) were measured in 80 children with PRS, and correlation analysis was conducted with the potential clinical influencing factors of the children. CBCT reconstruction of the panoramic film showed that the new bone formation was good at 3 to 4 months after MDO.

Purpose: Ollier's disease (multiple enchondromatosis) can cause severe lower limb length discrepancy and deformity in children. Osteotomy and limb lengthening with external fixation can correct the lower extremity deformity. There may be lesions in the osteotomy part (OP), and the internal fixation part of the external fixation(FP).

Article Synopsis
- The prolonged use of external fixation during distraction osteogenesis (DO) can heighten complications, while bone marrow mesenchymal stem cells (BMSCs) play a crucial role in bone regeneration due to their pro-angiogenic and osteogenic abilities.
- RSC-96, a type of Schwann cell, has been shown to promote the proliferation, migration, and differentiation of BMSCs when co-cultured, enhancing both bone formation and blood vessel development through neurotrophic factor secretion and activation of specific signaling pathways.
- In a rat DO model, RSC-96's conditioned medium improved bone healing outcomes, with notable increases in gene expression markers for osteogenesis and angiogenesis, alongside positive radiological and biomechanical assessments.
Craniosynostosis surgery practice patterns in the United States: what are we doing and how are we doing it?

Objective: The surgical management of craniosynostosis varies without consensus on technique or standard outcomes reporting. The authors of this study aimed to investigate current surgical management of craniosynostosis in the United States.
Methods: Two hundred seventy-five surgeons actively treating craniosynostosis in the United States were surveyed.
Locking compression plate as a sequential external fixator following the distraction phase for the treatment of tibial bone defects caused by fracture-related infection: experiences from 22 cases.

Background: The purpose of this study was to report the clinical and psychological outcomes of using a locking compression plate (LCP) as a sequential external fixator following the distraction phase in the treatment of tibial bone defects caused by fracture-related infection (FRI).
Methods: We retrospectively analyzed the clinical records and consecutive X-ray images of patients with tibial bone defects who were treated with an LCP as a sequential external fixator following the distraction phase, between June 2017 and December 2022. The ASAMI criteria were applied to assess the bone and functional outcomes, and postoperative complications were evaluated by using the Paley classification.
