Orbital Wall Fractures and Ocular Injury: Impact on Management.

Orbital wall fractures are often associated with concomitant ocular injury. In some cases, detection and treatment of such injuries requires ophthalmology evaluation. To identify a change in ocular management as a result of ophthalmology evaluation in patients with orbital wall fractures.

3D printed composite scaffolds with dual small molecule delivery for mandibular bone regeneration.

Functional reconstruction of craniomaxillofacial defects is challenging, especially for the patients who suffer from traumatic injury, cranioplasty, and oncologic surgery. Three-dimensional (3D) printing/bioprinting technologies provide a promising tool to fabricate bone tissue engineering constructs with complex architectures and bioactive components. In this study, we implemented multi-material 3D printing to fabricate 3D printed PCL/hydrogel composite scaffolds loaded with dual bioactive small molecules (i.

Platelet-Rich Plasma for the Treatment of Tissue Infection: Preparation and Clinical Evaluation.

The clinical application of platelet-rich plasma (PRP) has been widely studied for its effects on trauma or injury repair/regeneration, however the antibacterial property of PRP has been overlooked. Increasing evidence suggests PRP as a good antibacterial agent and that it could help prevent/treat tissue infection. This review emphasizes the importance of PRP's antibacterial property and summarizes the preclinical and clinical findings regarding the application of PRP in the prevention and treatment of wound and bone infection.

Prevascularization of 3D printed bone scaffolds by bioactive hydrogels and cell co-culture.

Vascularization is a fundamental prerequisite for large bone construct development and remains one of the main challenges of bone tissue engineering. Our current study presents the combination of 3D printing technique with a hydrogel-based prevascularization strategy to generate prevascularized bone constructs. Human adipose derived mesenchymal stem cells (ADMSC) and human umbilical vein endothelial cells (HUVEC) were encapsulated within our bioactive hydrogels, and the effects of culture conditions on in vitro vascularization were determined.

Short-term hypoxic preconditioning promotes prevascularization in 3D bioprinted bone constructs with stromal vascular fraction derived cells.

Reconstruction of complex, craniofacial bone defects often requires autogenous vascularized bone grafts, and still remains a challenge today. In order to address this issue, we isolated the stromal vascular fraction (SVF) from adipose tissues and maintained the phenotypes and the growth of endothelial lineage cells within SVF derived cells (SVFC) by incorporating an endothelial cell medium. We 3D bioprinted SVFC within our hydrogel bioinks and conditioned the constructs in either normoxia or hypoxia.

Malignant PEComa involving the mandible: report of a unique case.

We report a unique case of a malignant perivascular epithelioid cell neoplasm (PEComa) presenting as a slow-growing mandibular lesion in a 77-year-old Caucasian female. Primary osseous involvement by PEComas is rare. This is the first reported case of a malignant PEComa arising within the jaw.
