Computer-assisted surgical (CAS) planning tools are available for craniofacial surgery, but are usually based on computer-aided design (CAD) tools that lack the ability to detect the collision of virtual objects (i.e., fractured bone segments). We developed a CAS system featuring a sense of touch (haptic) that enables surgeons to physically interact with individual, patient-specific anatomy and immerse in a three-dimensional virtual environment. In this study, we evaluated initial user experience with our novel system compared to an existing CAD system...

Titania nanotubes (TNTs) engineered on titanium (Ti) surfaces (i.e. TNT/Ti) and loaded with specific drugs have been recognised as a promising solution for localised therapeutic delivery to address several medical problems not feasible with conventional drug administration. We propose the use of TNT/Ti protein-releasing implants to treat paediatric craniofacial abnormality in craniosynostosis caused by premature fusion of cranial sutures. In this study, we have analysed the biological response of human suture mesenchymal cells (SMCs), extracted from two different patients undergoing craniofacial reconstruction surgery, at the TNT/Ti implant surface...

High-grade craniofacial osteosarcoma (CFOS) is an aggressive malignancy with a poor prognosis. Our goals were to evaluate treatment outcomes in those treated at a single referral institution over 35 years and to compare our results to the available literature. A retrospective analysis of all 42 patients treated between 1980 and 2015 at Oslo University Hospital, Norway, identified in a prospectively collected database, was conducted. Mean follow-up was 79.6 months. Overall survival at 2 and 5 years was 70...

BACKGROUND: Since the description of the free fibula flap by Taylor in 1975, many flaps composed of bone have been described. This review documents the history of vascularised bone transfer and reflects on the current understanding of blood supply in an effort to define all clinically described osseous flaps. METHODS: A structured review of MEDLINE and Google Scholar was performed to identify all clinically described bone flaps in humans. Data regarding patterns of vascularity were collected where available from the anatomical literature...

The superior orbital fissure syndrome (SOFS) is an uncommon complication rarely occurring in association with craniofacial trauma. Work-up of a patient injured by a traumatic right orbitozygomatic complex fracture and SOFS is presented. Accurate computed tomography scan and three-dimensional reconstruction showed a medial displacement of the lateral orbital wall, compressing the right superior orbital fissure (SOF), without intraorbital bone fragment displacement or hemorrhage. Imaging also revealed a frontosphenotemporal fracture, according to Pellerin et al, that is, frequently associated with visual impairment...

INTRODUCTION: Frontoethmoidal meningoencephalocele (FMEC) is a rare congenital anomaly characterized by herniation of brain tissue and meninges through a defect in the cranium and associated with facial dysmorphism. Treatment modalities include extra cranial, transcranial, or combined craniofacial approaches. The combined approach is considered the best treatment choice. METHODS: Twelve patients with FMEC aging from 6 months to 4 years were treated by single-stage combined craniofacial approach between July 2011 and July 2015...

Pain is a disabling symptom and is often the foremost symptom of conditions for which patients undergo neurorehabilitation. We systematically searched the PubMed and Embase electronic databases for current evidence on the frequency, evolution, predictors, assessment, and pharmacological and non-pharmacological treatment of pain in patients with headache, craniofacial pain, low back pain, failed back surgery syndrome, osteoarticular pain, myofascial pain syndrome, fibromyalgia, and chronic pelvic pain. Despite the heterogeneity of published data, consensus was reached on pain assessment and management of patients with these conditions and on the utility of a multidisciplinary approach to pain therapy that combines the benefits of pharmacological therapy, physiotherapy, neurorehabilitation, and psychotherapy...

Craniofacial bone defects are challenging problems for maxillofacial surgeons over the years. With the development of cell and molecular biology, gene therapy is a breaking new technology with the aim of regenerating tissues by acting as a delivery system for therapeutic genes in the craniofacial region rather than treating genetic disorders. A systematic review was conducted summarizing the articles reporting gene therapy in maxillofacial surgery to answer the question: Was gene therapy successfully applied to regenerate bone in the maxillofacial region? Electronic searching of online databases was performed in addition to hand-search of the references of the included articles...

INTRODUCTION: Presentation at scientific meetings is the usual first step to communicate new research findings. However, without subsequent, peer-reviewed publication, the wider propagation and the permanent documentation of important scholarly work may be lost. Our aim was to analyze and compare the publication status of the work presented at the European Association of Plastic Surgeons' (EURAPS) and at the American Association of Plastic Surgeons' (AAPS) annual meetings. MATERIALS AND METHODS: By using the abstract booklets from the annual meetings, all presentations given over a 10-year period (2000-2009) were analyzed...

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...

Hemangiopericytomas are soft tissue tumors composed of pericytic cells that are characterized by their "staghorn" vascular branching and their variable clinical presentation. Fifteen to 25% of all HPC occur in the head and neck, with only 5% found in the nose or paranasal sinuses. Sinonasal hemangiopericytoma (SNHPC) is considered distinct from its soft tissue counterpart - the former showing a more uniform cellular organization, has convincing pericytic differentiation and is associated with a far better prognosis...

Repair of calvarial bony defects remains challenging for craniofacial surgeons. Injury experiments on animal calvarial bones are widely used to study healing mechanisms and test tissue engineering approaches. Previously, we identified Gli1+ cells within the calvarial sutures as stem cells supporting calvarial bone turnover and injury repair. In this study, we tested the regenerative capacity of the suture region compared with other areas of calvarial bone. Injuries were made to mouse sagittal sutures or other areas of the calvarial bone at varying distances from the suture...

Neurofibroma is a slow growing benign tumour of the peripheral nerve sheath which is frequently associated with neurofibromatosis type 1 (Prakash et al., 2014). Isolated solitary occurrence of neurofibroma in the maxillary sinus is rare with only 29 reported cases in the literature. We present a rare case of a 70-year-old gentleman who was referred to ENT with a right maxillary sinus neurofibroma with extension into the right inferior orbit. He has significant proptosis, ptosis, and limitation in abduction of the right eye...

Osteosarcoma in the craniofacial region is rare. A 43-year-old female, the patient, self-detected a 3-cm tumor of the right frontoparietal region 4 months before. An incisional biopsy was performed and a osteosarcoma was reported. At admission, a 4 × 5 cm tumor was present on the right frontoparietal region, without extending to the orbital region but the patient underwent surgery 2 months after admission. The delay was due to 2 episodes of upper respiratory tract infection that required resolution. At the time of surgery the tumor measured 8 × 9 cm...

Craniofacial clefts are rare entities, with an incidence reported as 1.43 to 4.85 per 100,000 births. The Tessier number 3 cleft, the most medial of the oblique clefts, can manifest as clefting of the lip between the canine and lateral incisors, colobomas of the nasal ala and lower eyelid, and inferior displacement of the medial canthus-frequently disrupting the lacrimal system with extreme variability in expressivity (Eppley).Literature on cleft lip repair is extensive and has evolved to incorporate anthropometric techniques, based on identifiable landmarks and anthropometric measurements that are compared with contralateral unaffected anatomy or population means and tracked over time to assess impact on growth...

BACKGROUND: Although craniofacial bone correction is the essential step in hypertelorbitism correction, the final result depends on the management of soft tissue deformities. The purpose of this study was to review our surgical strategies for soft tissue reconstruction in hypertelorbitism correction. METHODS: A retrospective study was performed of consecutive patients with hypertelorbitism, undergoing hypertelorbitism correction between 2007 and 2014. All aspects related to the craniofacial surgical procedures (number and type of procedures, outcomes, and complications) were verified through medical records, clinical photographs, and interviews with all patients...

OUTCOME OBJECTIVE: For over fifty years, otolaryngologists, allergists, and immunologists have debated the effect of adenoidectomy or adenotonsillectomy on asthma outcomes in children. Although some have suggested that adenotonsillectomy may contribute to the subsequent development of asthma in children, others have argued that a common mechanism may cause both upper and lower airway disease, and that children who have symptoms severe enough to warrant adenotonsillectomy are also at increased risk of asthma and atopic disease...
