PURPOSE OF THE STUDY: This study was to establish a three-dimensional (3D) coordinate system and to study the normal dimensions of intra-orbital structures in Chinese adults. MATERIALS AND METHODS: One hundred and forty-five adult Chinese were selected from patients who had undergone cranio-facial computed tomography scans with diagnosis other than orbital or ocular abnormality. An orbital 3D coordinate system was built on the basis of the scans. Morphological variables of intra-orbital structures were measured in this coordinate system...

Tricortical cortico-cancellous bone allografts from the anterior iliac crest are routinely used in revision arthroplasty and to treat non-union. Trans-iliac herniation (TIH) has been reported as an exceptional complication after extensive graft harvesting. The various reconstruction techniques include isolated parietal reconstruction and combined parietal and bone reconstruction using allografts or a spacer to reconstruct the bone defect. No previous study has evaluated a combined reconstruction technique involving both bone reconstruction with a titanium plate and abdominal wall reconstruction with a parietal reinforcement prosthesis...

INTRODUCTION: Orthodontists have long tried to predict future growth. It is one of the most difficult goals to achieve precisely despite the different methods of growth forecasting. A simple technique based on clinical and radiological analyses of the nose and premaxilla makes it possible, using no measurements, to accurately predict future maxillary growth and to deduce the therapeutic indications. A morphologic study of the nose is also an important item in the diagnosis of cranio-facial syndromes...

Eagle's syndrome is a condition associated with the elongation of the styloid process or calcification of the stylohyoid ligament, clinically characterised by throat and neck pain, radiating into the ear. In this report, we describe the case of a 60-year-old woman who presented with a severe unilateral trigeminal and glossopharyngeal neuralgia. The patient was subjected to conservative therapy for four months and did not report improvement of the symptoms. After several consultations with different physicians, a diagnosis was accomplished by radiological investigation (multidetector computer tomography with multi-planar reconstructions and 3D volumetric reconstructions)...

Fibrous dysplasia is a benign bone disease, presenting as monostotic or polyostotic lesions, or as part of a syndrome (McCune-Albright/Mazabraud). Its clinical course shows a variegated picture and the progression of its growth is unpredictable. In the workup of 39 fibrous dysplasia cases in the cranio-facial area, four cases presented fast growth tendencies, of which two patients with McCune-Albright syndrome showed malignant-like rapid growth. This local aggressive form is extremely rare, and the concept of this issue has not been clearly defined...

This review encompasses different pre-clinical bioengineering approaches for periodontal tissues, maxillary jaw bone, and the entire tooth. Moreover, it sheds light on their potential clinical therapeutic applications in the field of regenerative medicine. Herein, the electrospinning method for the synthesis of polycaprolactone (PCL) membranes, that are capable of mimicking the extracellular matrix (ECM), has been described. Furthermore, their functionalization with cyclosporine A (CsA), bone morphogenetic protein-2 (BMP-2), or anti-inflammatory drugs' nanoreservoirs has been demonstrated to induce a localized and targeted action of these molecules after implantation in the maxillary jaw bone...

BACKGROUNDː Functional Endoscopic Sinus Surgery (FESS) is a minimally-invasive surgical technique for patients with paranasal sinus pathology. Surgical bleeding reduces operative field visibility and increases the incidence of serious complications. Epinephrine injection into the nasal mucosa and controlled hypotension are used to minimise bleeding. Hypotension carries risks and sometimes does not reduce surgical bleeding. The goal of this study is to discover which haemodynamic parameter better correlates with surgical bleeding...

BACKGROUND: Determining and restoring physiological vertical dimension of occlusion (VDO) is the critical step during complete mouth rehabilitation. The improper VDO compromises the aesthetics, phonetics and functional efficiency of the prosthesis. Various methods are suggested to determine the accurate VDO, including the facial measurements in the clinical situations with no pre-extraction records. The generalisation of correlation between the facial measurements to VDO is criticised due to gender dimorphism and racial differences...

Jae-Woo Heo, Ung Sik Jin
Treacher Collins syndrome is a congenital disorder that is characterized with a wide range of cranio-facial deformities. Zygomatic hypoplasia or aplasia is one of the key features, and surgical reconstruction of the consequent depression on the zygomatic area is deemed necessary by many patients. Various surgical options are available-injectables, alloplastic materials, autologous grafting, and autogenous tissue transfer. It depends on each patient which technique to use. Here, we present a clinical case, in which bilateral free groin flaps were adopted in attempt to resolve the remnant aesthetic deformity associated with zygomatic depression, despite a series of previous surgical efforts, in a 25-year-old Treacher Collins syndrome male patient...

INTRODUCTION: Traumatic brain injury (TBI) is one of the main causes of morbidity and mortality in young trauma patients with resultant multi-organ effects. Hypopituitarism following TBI can be debilitating and life threatening. TBI which causes hypopituitarism may be characterized by a single head injury, such as from a motor vehicle accident, or by chronic repetitive head trauma, as seen in combative supports including boxing, kick-boxing, and football. In the majority of cases, a diagnosis of hypopituitarism can be entirely missed resulting in severe neuro-endocrine dysfunction...

Isolated congenital vomer agenesis is a very rare and poorly understood condition. In the context of dental work-up by cone-beam computed tomography (CBCT), the explored volume of the facial bones occasionally reveals incidental abnormalities. We report the case of a 13-year old Caucasian female who underwent CBCT for the pre-treatment evaluation of primary failure of tooth eruption affecting the permanent right upper and inferior molars. CBCT depicted a large defect of the postero-inferior part of the nasal septum without associated soft tissue abnormality and without cranio-facial malformation or cleft palate...

OBJECTIVE: Dystonia is occasionally found in patients with Parkinson's disease (PD) and atypical parkinsonisms. However, systematic comparative analysis of the association between dystonia and parkinsonism have seldom been reported. The goals of this study are to compare the clinical characteristics and distributions of dystonia between PD, multiple system atrophy (MSA), progressive supranuclear palsy (PSP) and corticobasal degeneration (CBD). METHODS: We prospectively enrolled 176 patients who presented with dystonia and parkinsonism out of 1278 patients with parkinsonism...

Russell S Kirby
Although collectively they are fairly common, birth defects receive limited attention as a group of outcomes either clinically or from a public health perspective. This article provides an overview of the prevalence, trends and selected socio-demographic risk factors for several major birth defects, including neural tube defects, cranio-facial anomalies, congenital heart defects, trisomies 13, 18, and 21, and gastroschisis and omphalocele. Attention should focus on strengthening existing registries, creating birth defects surveillance programs in states that do not have them, and standardizing registry methods so that broadly national data to monitor these trends are available...

The Sonic Hedgehog (SHH) pathway is a key signaling pathway orchestrating embryonic development, mainly of the CNS and limbs. In vertebrates, SHH signaling is mediated by the primary cilium, and genetic defects affecting either SHH pathway members or ciliary proteins cause a spectrum of developmental disorders. SUFU is the main negative regulator of the SHH pathway and is essential during development. Indeed, Sufu knock-out is lethal in mice, and recessive pathogenic variants of this gene have never been reported in humans...

BACKGROUND: Pain is a very common condition in patient undergoing rehabilitation for neurological disease; however the presence of primary headaches and other cranio-facial pains, particularly when they are actually or apparently independent from the disability for which patient is undergoing rehabilitation, is often neglected. Diagnostic and therapeutic international and national guidelines, as well as tools for the subjective measure of head pain are available and should also be applied in the neurorehabilitation setting...

The authors present a case of a 42-year-old female admitted for disabling complex and atypical bilateral facial spasms associated with painful masticatory and motor ocular dystonic movements, difficult to fit in the definition of any known cranio-facial dyskinesias. MRI showed a left PICA loop invaginated into the brainstem, considered responsible of an hyperactive disorder of the brainstem nuclei neighboring the conflict. After microvascular decompression, the patient made a full recovery with complete disappearance of the paroxystic phenomena...
