BACKGROUND: Thyroid cancer is the fastest growing cancer in the United States. A small portion of differentiated thyroid cancers (DTCs; 2% to 13%) develop bone metastases, which can decrease a patient's survival rate by more than 60%. METHODS: A systematic literature search of studies, including patients with DTC with bone metastases, was conducted by following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A case series of patients with DTC diagnosed with bone metastases seen at our institution was also included...

BACKGROUND: Craniomaxillofacial reconstruction with patient-specific, customized craniofacial implants (CCIs) is ideal for skeletal defects involving areas of aesthetic concern-the non-weight-bearing facial skeleton, temporal skull, and/or frontal-forehead region. Results to date are superior to a variety of "off-the-shelf" materials, but require a protocol computed tomography scan and preexisting defect for computer-assisted design/computer-assisted manufacturing of the CCI. The authors developed a craniomaxillofacial surgical assistance workstation to address these challenges and intraoperatively guide CCI modification for an unknown defect size/shape...

PURPOSE: Because of less attention to the sagittal component of maxillary fractures, these fractures are often misdiagnosed and the reduction leading to maxillary transverse discrepancies is missed. Therefore, the purpose of this study was to identify factors associated with good or adverse postoperative outcomes of maxillary sagittal fractures. MATERIALS AND METHODS: This study was a single-center retrospective cohort study. The sample was composed of cases of maxillary sagittal fractures treated at the Department of Oral and Maxillofacial Surgery, Craniomaxillofacial Trauma Unit of Xi'an Jiaotong University (Xi'an, China) from January 2008 through December 2013...

Tissue-engineered approaches to regenerate bone in the craniomaxillofacial region utilize biomaterial scaffolds to provide structural and biological cues to stem cells to stimulate osteogenic differentiation. Bioactive scaffolds are typically comprised of natural components but often lack the manufacturability of synthetic materials. To circumvent this trade-off, we 3D printed materials comprised of decellularized bone (DCB) matrix particles combined with polycaprolactone (PCL) to create novel hybrid DCB:PCL scaffolds for bone regeneration...

Therapies using mesenchymal stem cell (MSC) seeded scaffolds may be applicable to various fields of regenerative medicine, including craniomaxillofacial surgery. Plastic compression of collagen scaffolds seeded with MSC has been shown to enhance the osteogenic differentiation of MSC as it increases the collagen fibrillary density. The aim of the present study was to evaluate the osteogenic effects of dense collagen gel scaffolds seeded with mesenchymal dental pulp stem cells (DPSC) on bone regeneration in a rat critical-size calvarial defect model...

INTRODUCTION: Several bioresorbable plating systems have become standard in pediatric craniosynostosis reconstruction. A comparison of these systems is needed to aid surgeons in the preoperative planning process. The authors aim to evaluate 1 institution's experience using Resorb-X by KLS Martin and Delta Resorbable Fixation System by Stryker (Stryker Craniomaxillofacial, Kalamazoo, MI). METHODS: A sample of patients with single-suture nonsyndromic craniosynostosis treated at St Louis Children's Hospital between 2007 and 2014 using either Resorb-X or Delta bioresorbable plating systems were reviewed...

There is a recognized need to reconstruct and restore complex craniomaxillofacial soft tissues. The objective of this article is to focus on the role that tissue engineering/regenerative medicine can play in addressing various barriers (vascularity, tissue bulk, volitional control, and esthetics) and impediments (timing, regional applicability/dissemination, and regulation by the US Food and Drug Administration) to optimal tissue reconstruction of complex soft tissue structures. We will use the lips as an example to illustrate our points...

Orbital fractures are a common result of facial trauma. Sequelae and indications for repair include enophthalmos and/or diplopia from extraocular muscle entrapment. Alloplastic implant placement with careful release of periorbital fat and extraocular muscles can effectively restore extraocular movements, orbital integrity, and anatomic volume. However, rare but devastating complications such as retrobulbar hematoma (RBH) can occur after repair, which pose a risk of permanent vision loss if not addressed emergently...

There are a variety of biomedical materials applied in craniomaxillofacial and dental clinical practice, plastic surgery, otorhinolaryngology and neurosurgery. With the increasing investment for the biomedical materials study, considerable progress has been obtained in biomaterials research. But overall, the field of biomaterials in China is still in a backward state. The development of advanced manufacturing technology has put forward new demands for the research of biological materials and has expanded the application, but at present, there are few biomaterials that meet the requirements...

This work deals with the mechanical characterization by depth-sensing indentation (DSI) of PLLA and PLDA composites reinforced with micro-particles of Mg (up to 15wt%), which is a challenging task since the indented volume must provide information of the bulk composite, i.e. contain enough reinforcement particles. The composites were fabricated by combining hot extrusion and compression moulding. Physico-chemical characterization by TGA and DSC indicates that Mg anticipates the thermal degradation of the polymers but does not compromise their stability during processing...

INTRODUCTION: Congenital intraoral synechias are adhesions of intraoral structures involving soft tissue. These conditions and another anomaly called ankyloblepharon filiforme adnatum, which is partial fusion of the eyelid margins by bands of tissue, are rarely reported in the literature. The association of both anomalies of the craniomaxillofacial region is an even more unusual finding. PURPOSE: This article adds more information to the literature by reporting a case of a neonate with a rare association of bilateral synechia between the jaws, fusion of buccal mucosa to the ridges and between the tongue and palate, and ankyloblepharon filiforme adnatum in both eyes, without any other facial or systemic malformation...

In craniomaxillofacial (CMF) surgery, a reliable way of simulating the soft tissue deformation resulted from skeletal reconstruction is vitally important for preventing the risks of facial distortion postoperatively. However, it is difficult to simulate the soft tissue behaviors affected by different types of CMF surgery. This study presents an integrated bio-mechanical and statistical learning model to improve accuracy and reliability of predictions on soft facial tissue behavior. The Rubin-Bodner (RB) model is initially used to describe the biomechanical behavior of the soft facial tissue...

Facial trauma causes significant of morbidity in the United States. With injuries varying widely, the clinical benefits of antibiotics use in facial fracture treatment are not easily determined. The pediatric population is more predisposed to craniofacial trauma secondary to their increased cranial mass to body ratio. All patients with traumatic injury should be assessed according to the Advanced Trauma Life Support protocol. This article discusses the types and prevalence of injuries and approaches to management...

The works of Hippocrates known in the Western World as the Corpus Hippocraticum have dominated medical thought and surgical practice for centuries. A substantial part of the Hippocratic Collection is dedicated to the description of injuries pertinent to Cranio-maxillofacial surgery and their management. Hippocrates has reached this level of surgical skill despite the limited pre-recorded knowledge and the restriction to perform post-mortem dissections.

Peripheral nerve injury is a common clinical entity, which may arise due to traumatic, tumorous, or even iatrogenic injury in craniomaxillofacial surgery. Despite advances in biomaterials and techniques over the past several decades, reconstruction of nerve gaps remains a challenge. Autografts are the gold standard for nerve reconstruction. Using autografts, there is donor site morbidity, subsequent sensory deficit, and potential for neuroma development and infection. Moreover, the need for a second surgical site and limited availability of donor nerves remain a challenge...
