Despite humanitarian otolaryngology groups traveling in record numbers to resource-limited areas treating pediatric otolaryngology disease processes and training local providers, there remains a large burden of unmet needs. There is a meager amount of published information that comes from the developing world from an otolaryngology standpoint. As would be expected, the little information that does comes involves some of the most common pediatric otolaryngology diseases and surgical burdens including childhood hearing loss, otitis media, adenotonsillectomies, airway obstructions requiring tracheostomies, foreign body aspirations, and craniomaxillofacial surgeries, including cleft lip and palate...

Three-dimensional printing of patient-specific models is being used in various aspects of craniomaxillofacial reconstruction. Printing is typically outsourced to off-site vendors, with the main disadvantages being increased costs and time for production. Office-based 3-dimensional printing has been proposed as a means to reduce costs and delays, but remains largely underused because of the perception among surgeons that it is futuristic, highly technical, and prohibitively expensive. The goal of this report is to demonstrate the feasibility and ease of incorporating in-office 3-dimensional printing into the standard workflow for facial fracture repair...

Cross-disciplinary collaborations have initiated translational studies in an effort to harness naturally occurring diseases in companion animals to accelerate the development of new treatment modalities, drugs, and device inventions. These synergistic collaborations can identify clinically relevant models that offer the opportunity to conduct rigorous translational investigations. However, the relationship between craniomaxillofacial diseases in companion animals and humans has been widely overlooked. We report here an innovative and visionary 2-d symposium that was organized to gather professionals working on craniomaxillofacial disorders and solutions in humans and/or animals from multiple disciplines, including veterinary physicians, basic scientists, biomedical engineers, physicians, and dentists...

The need to restore bone loss in maxilla and mandible has led to find natural bone substitutes, such as fresh autogenous bone grafts. Fresh autogenous bone grafts (FABGs) have a remarkable capacity to induce new bone formation, a phenomenon called ‘osteoinduction.’ FABGs are useful in craniomaxillofacial and oral applications to restore bone deficiencies. The isolation of those proteins believed to be responsible for the osteoinductive activity of FABGs, namely Natural Bone Morphogenetic Proteins (NBMPs), led to a new era in bone regeneration...

PURPOSE: A biodegradable magnesium alloy system has been developed as a substitute for conventional plates and screws made of titanium or absorbable polymer. However, previous studies were limited to small animal experiments using screws or wires. In the present study, we preliminarily evaluated the biocompatibility and effectiveness of human standard-size biodegradable magnesium-based plates and screws in facial fractures of beagles. MATERIALS AND METHODS: Fracture lines were created bilaterally in the zygomatic arches of 6 beagles...

To evaluate the clinical results of reconstruction orbital defect with craniomaxillofacial implant. Three patients with orbital defect were treated with ten implants. The magnetic abutments were attached six months after one stage operation and the prostheses were fabricated. Within 11 to 47 months of follow up, all implants were stable with successful osseointegration. The prosthesis fit the orbital defects well. Reconstruction of orbital defect with craniomaxillofacial implant can be considered as a viable alternative treatment...

Gardner syndrome (GS) is a rare genetic disorder. Dentists play an important role in diagnosis considering that craniomaxillofacial osteomas are a major criteria for GS. We report a 26-year-old male patient who referred to our department with toothache. On routine panoramic radiographic examination, multiple radiopaque masses were detected incidentally. In addition, on extraoral examination, a soft tissue tumor was detected on his shoulder. The patient was referred to the gastroenterology department and intestinal polyps were detected in the colon...

There is a need in orthopaedic and craniomaxillofacial surgeries for materials that are easy to handle and apply to a surgical site, can fill and fully conform to the bone defect, and can promote the formation of new bone tissue. Thermoresponsive polymers that undergo liquid to gel transition at physiological temperature can potentially be used to meet these handling and shape-conforming requirements. However, there are no reports on their capacity to induce in vivo bone formation. The objective of this research was to investigate whether the functionalization of the thermoresponsive, antioxidant macromolecule poly(poly-ethyleneglycol citrate-co-N-isopropylacrylamide) (PPCN), with strontium, phosphate, and/or the cyclic RGD peptide would render it a hydrogel with osteoinductive properties...

Fibrous dysplasia (FD) is a disturbance of the mesenchymal tissue that accounts for 2.5% of all bone tumors and more than 7% of nonmalignant bone tumors. In the craniomaxillofacial region, FD affects the calvaria, skull base, zygoma, and jaws, the prevalent site being the maxilla (50% of cases). Therapy for craniomaxillofacial FD is surgical. The goals of surgery are to prevent functional disorders and restore facial symmetry, volume, and contour. In this article, we present a case of a young female patient affected by right orbital-zygomatic-maxillary FD...

Generating accurate 3D models from cone-beam computed tomography (CBCT) images is an important step in developing treatment plans for patients with craniomaxillofacial (CMF) deformities. This process often involves bone segmentation and landmark digitization. Since anatomical landmarks generally lie on the boundaries of segmented bone regions, the tasks of bone segmentation and landmark digitization could be highly correlated. However, most existing methods simply treat them as two standalone tasks, without considering their inherent association...

Osteomas are benign, slow-growing tumors that most frequently occur in the craniomaxillofacial region. These tumors are mostly asymptomatic and are generally found incidentally. A giant osteoma is generally considered to be greater than 30 mm in diameter or 110 g in weight. A 35-year-old female presented to us with complaints of a firm mass that showed continuous growth on the forehead following trauma. A hairline incision was made to expose the osteoma. Biopsy of the tumor confirmed a osteoma. There were no complications after surgery...

PURPOSE: The use of technology to aid in assessment, planning, and management of complex craniomaxillofacial injuries is increasingly common. Preoperative computed tomography (CT) evaluation is considered the standard of care, and intraoperative imaging is becoming increasingly accessible. Limited data exist regarding the implication of intraoperative CT on decision making in the management of all sites of facial fractures. The purposes of this study were to characterize the use of an intraoperative CT scanner for craniomaxillofacial surgery within our institution, to quantify the effect of intraoperative CT on surgical decision making, and to attempt to provide guidance on when to use this technology...
