BACKGROUND/PURPOSE: Photograph-based visual scoring has been used for evaluation of facial morphological changes. Here, we describe a three-dimensional computed tomography (3D-CT) method for objective analysis of facial and intra-facial (subcutaneous) changes. The effects of facial massage were examined using both methods. METHODS: Subjects were 12 healthy female volunteers without facial scars or deformation (age 30-54 years, mean 39.4 years). Photograph-based scoring of massage-induced morphological changes was done at the nasolabial folds, upper, lower and lateral cheeks and lower eyelids...

Stomatognathic system is strictly correlated to other anatomical regions; many studies investigated relationship between temporomandibular joint and posture, several articles describe cranio-facial pain from dental causes, such as trigger points. Until now less interest has been given to connections between dental occlusion and ophthalmology, even if they are important and involving. Clinical experience in dental practice claims that mandibular latero-deviation is connected both to eye dominance and to defects of ocular convergence...

INTRODUCTION: Facial symmetry has always been a longstanding objective of orthognathic surgery. Patients that present significant facial asymmetry desire functional dental occlusion but also seek to enhance their facial esthetics. In that regard, different surgical techniques have been proposed to enhance facial recontouring. MATERIALS AND METHODS: Through a clinical case report and a literature review, this article explores the use of allopastic microporous titanium implants in volumetric corrections of the face...

INTRODUCTION: The mandible consists of different segments, each of which possess its own specific characteristics regarding emergence, ossification during growth and pathologies. Orthodontists need to be very familiar with these developmental anomalies if they are to avoid failure in their orthopedic or orthodontic treatments and in order to understand the reasons for the lack of success of "conventional" treatments. Each segment must develop correctly if the mandible is to achieve optimal development and occupy a normal position within the cranio-facial complex...

BACKGROUND: Maxillofacial fractures occur in a significant proportion worldwide and can occur as an isolated injury or in combination with other severe injuries including cranial, spinal, and upper and lower body injuries requiring prompt diagnosis with possible emergency interventions. The epidemiology of facial fractures varies with regard to injury type, severity, and cause and depends on the population studied. Hence, understanding of these factors can aid in establishing clinical and research priorities for effective treatment and prevention of these injuries...

The soluble osteogenic molecular signals of the transforming growth factor-β (TGF-β) supergene family are the molecular bases of the induction of bone formation and postnatal bone tissue morphogenesis with translation into clinical contexts. The mammalian TGF-β3 isoform, a pleiotropic member of the family, controls a vast array of biological processes including the induction of bone formation. Recombinant hTGF-β3 induces substantial bone formation when implanted with either collagenous bone matrices or coral-derived macroporous bioreactors in the rectus abdominis muscle of the non-human primate Papio ursinus...

Many types of surgical osteotomies of the cranio-facial skeleton relay on adequate surgical field preparation. Placement and stabilization of nasotracheal tube during orthognathic surgery is very important. In most cases, long-lasting surgery includes various surgical maneuvers around patient's skull, which depend on accurate nasotracheal tube stabilization. Usage of adhesive plasters for heavy anesthetic tube connector placement and stability might result in tube instability and local disfigurement of nasal projection and visibility in the nasal and infraorbital areas...

This patient report describes simultaneous bimaxillary orthognathic surgery and mandibular reconstruction by means of three-dimensional (3D) planning, 3D printed biocompatible surgical wafers, and 3D selective-laser sintered titanium implant. A 26-year-old male patient presented with a left mandibular defect secondary to trauma. The whole body of the mandible on the left hand side was deficient with a narrow connection with the remaining left condyle. He had undergone orthodontic treatment for 18 months and was ready to undergo bimaxillary orthognathic surgery...

BACKGROUND AND AIMS: Despite the fact that implants are sterilized, antiseptic techniques are applied and systemic antibiotics are routinely administered prior to and after craniofacial surgery, infection rates between 3% and 40% are still reported for alloplastic implants, urging for implant removal. The present study focuses on the development of a fiber-reinforced composite (FRC) implant for craniofacial reconstruction with antimicrobial properties. METHODS: A new fiber-reinforced composite coated with gentamicin was developed and tested for bacterial adherence and antibacterial efficiency, using two of the most involved bacterial strains in the postoperative infections: Staphylococcus aureus and Pseudomonas aeruginosa...

Cellular homeostasis is maintained by the highly organized cooperation of intracellular trafficking systems, including COPI, COPII, and clathrin complexes. COPI is a coatomer protein complex responsible for intracellular protein transport between the endoplasmic reticulum and the Golgi apparatus. The importance of such intracellular transport mechanisms is underscored by the various disorders, including skeletal disorders such as cranio-lenticulo-sutural dysplasia and osteogenesis imperfect, caused by mutations in the COPII coatomer complex...

Mucormycosis and aspergillosis are two opportunistic fungal infections, which can evolve into life-threatening complications. They generally affect patients with relevant risk factors such as immunocompromisation or long-term use of antibiotics or corticosteroids. Treatment usually combines medical and surgical approaches, often including extended necrosectomies, although the prognosis of generalized fungal infections is very poor. In this paper, we present the case of a 17-year-old girl affected by combined aspergillosis and mucormycosis, following treatment of a recurrent glioma...

Regulation of gene expression at the level of transcriptional elongation has been shown to be important in stem cells and tumour cells, but its role in the whole animal is only now being fully explored. Neural crest cells (NCCs) are a multipotent population of cells that migrate during early development from the dorsal neural tube throughout the embryo where they differentiate into a variety of cell types including pigment cells, cranio-facial skeleton and sensory neurons. Specification of NCCs is both spatially and temporally regulated during embryonic development...

Polyetherketoneketone (PEKK) a high performance thermoplastic polymer that is FDA-approved for cranio- and maxillo-facial as well as spineal surgery. We studied the viability, growth and osteogenic differentiation of bone marrow-derived human and sheep mesenchymal stem cells (MSC) in combination with a 3D scaffold made of PEKK using different cell-based assays. To investigate if autologous MSC, either undifferentiated or osteogenically pre-differentiated, augmented bone formation after implantation, we implanted cell-seeded 3D PEKK scaffolds into calvarial defects in sheep for 12 weeks...

Interpersonal violence (IPV) and heavy alcohol consumption are major problems in the Western Cape Province of South Africa. Cranio-maxillofacial fractures, particularly nasal and zygomatic bone fractures, as well as isolated radial fractures (Colles fractures) and ulnar shaft fractures (parry fractures), are indicative of IPV, while alcoholic liver disease (ALD) is the consequence of chronic alcohol abuse. We therefore aim to investigate whether a significant association exists between the prevalence of cranio-maxillofacial fractures and parry fractures and ALD in a Western Cape population...

The figurative arts and precisely the ancient Pompeian wall paintings portraits can provide an additional source of information in supplementing bio-anthropological studies. There are several genetic diseases with a wide spectrum of congenital bone stigmata in association to distinctive facial features. Gorlin-Goltz syndrome, also named nevoid basal cell carcinoma syndrome, is an autosomal dominant syndrome characterized by unusual skeletal changes, such as macrocephaly, facial asymmetry, hypertelorism, frontal and parietal bossing caused by germline mutations of the gene PTCH1...

PURPOSE: Mandibular fractures are amongst the most common facial fractures and are usually treated by open reduction and internal fixation (ORIF). Inferior alveolar nerve (IAN) injuries are seen frequently in mandibular fractures as well as after ORIF of these fractures due to the exposition and the close proximity of the nerve during fracture reduction. Therefore the continuity of the IAN can be disrupted. Permanent injury to the IAN can result in diminished quality of life. This retrospective study was designed to objectively analyse the incidence and the outcome of pre- and postoperative mental nerve hypoesthesia after ORIF of mandibular fractures...

BACKGROUND: Decreases in the rates of traditional autopsy (TA) negatively impact traumatology, especially in the areas of quality improvement and medical education. To help enhance the understanding of trauma-related mortality, a number of initiatives in imaging autopsy (IA) were conceived, including the postmortem computed tomography ("CATopsy") project at our institution. Though IA is a promising concept, few studies directly correlate TA and IA findings quantitatively. Here, we set out to increase our understanding of the similarities and differences between key findings on TA and IA in a prospective fashion with blinding of pathologist and radiologist evaluations...

INTRODUCTION: Beta thalassemia is a blood dyscrasia that caused a marked expansion of active marrow spaces and extramedullary haematopoiesis results. In these patients various alterations and abnormalities affects different body areas, including increased risk of sinusitis. The marrow expansion in the facial bones results in delay in pneumatisation of the sinuses, overgrowth of the maxillae, and forward displacement of the upper incisors with skeletal deformities. In current literature, maxillary sinuses are not deeply evaluated by CT scan studies in these kind of patients...

G M Gordon, M Steyn
A recent review paper on cranio-facial superimposition (CFS) stated that "there have been specific conceptual variances" from the original methods used in the practice of skull-photo superimposition, leading to poor results as far as accuracy is concerned. It was argued that the deviations in the practice of the technique have resulted in the reduced accuracies (for both failure to include and failure to exclude) that are noted in several recent studies. This paper aims to present the results from recent research to highlight the advancement of skull-photo/cranio-facial superimposition, and to discuss some of the issues raised regarding deviations from original techniques...
