We describe a patient with traumatic carotid-cavernous fistula (CCF), subsequently developing contralateral extensive hemorrhagic venous infarction from retrograde venous reflux into the opposite basal vein of Rosenthal. A 54-year-old woman was involved in a motor vehicle accident and sustained severe traumatic brain injury. Two months later, she developed bilateral proptosis and audible bruit. Magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) of the brain demonstrated the right direct CCF...

PURPOSE: Endoscopic sinus surgery (ESS) is a well-established treatment for chronic rhinosinusitis (CRS). However, ESS for frontal sinusitis remains complicated and challenging. The aim of this study was to identify the relationship between residual frontal recess cells and primary ESS failure in the frontal sinus. METHODS: We prospectively collected information on 214 sides of 129 patients with CRS who underwent standard ESS from June 2010 to May 2011. To identify risk factors, we retrospectively analyzed clinical data and computed tomography (CT) images before and 3 months after surgery...

Cardiovascular autonomic neuropathy (CAN) is a well known prognostic marker in diabetes. A large angle between the QRS- and the T-wave vector (QRS-T angle) in the electrocardiogram (ECG) has recently been introduced as another marker of poor prognosis. AIM: To assess and compare the long-term predictive power of the frontal plane QRS-T angle with CAN in people with diabetes. METHODS: In 1992-93 people with diabetes in the municipality of Horsens, Denmark, were identified by the prescription method andan age and gender stratified sample of 240 individuals with diabetes were randomly selected...

BACKGROUND: Extracranial metastasis (ENM) of meningiomas is extremely rare, and typically occurs several years after a primary tumor is diagnosed. However, the genetic changes underlying ENM events have not yet been investigated. CASE PRESENTATION: A 58-year-old male patient was sent to the emergency room of our hospital because of a sudden fall. Magnetic resonance imaging detected a mass at the right frontal sagittal sinus. He underwent tumor resection and recovered well, but post-operative computed tomography revealed three lumps on the right side of his chest...

Woake's syndrome (WS) is a recurrent nasal polyposis, accompanied by broadening of the nose, frontal sinus aplasia, dyscrinia, and bronchiectasis. There has been no previous report on anesthetic management in patients with WS. We describe a case involving a 13-year-old male patient with WS who was scheduled for septorhinoplasty for necrotic ethmoiditis. Anesthesia was induced and maintained with propofol and remifentanil using a target-controlled infusion device. The anesthetic considerations of this rare syndrome and the advantages of an intravenous infusion method over local and volatile anesthesia for these patients are discussed...

Comminuted fractures of the anterior table of the frontal sinus involving frontonasal ducts are traditionally treated with sinus obliteration. This technique entails precise mucosa removal which requires unimpeded visualization of the bony recesses. To achieve adequate access to the mucosa, temporary removal of a large part of the frontal bone may often be necessary. This in turn increases fracture comminution requiring placement of additional hardware associated with the risk for bony malalignment, infection, plate palpability, and visibility, especially in thin-skin individuals...

Introduction Thermography is a form of radiography that images the skin surface temperature. Thermograms are pictorial representations of thermal maps of the entire body's outer surface. Thermography was applied as an attempt to evaluate its usefulness in the diagnosis of chronic sinusitis (CS). Hence, this study was done to determine the diagnostic value of thermography for patients suffering from CS. Methodology Patients attending the Department of Otorhinolaryngology and Head and Neck Surgery over a two years' duration with symptoms suggestive of CS were included in this diagnostic evaluation study...

A population of patients in Amsterdam with midfacial fractures was studied. Traffic accidents were found to be the most common cause, followed by violence and falls. The zygomatic complex was the most common fracture site. The majority of surgically treated patients consisted of men between 20 and 29 years of age. In addition to fracture displacement, indicative factors for surgery appear to be age, comorbidity and the presence or absence of functional problems. 8.1% of the surgically treated patients appear to have suffered brain damage...

Through phenotypic plasticity, bones can change in structure and morphology, in response to physiological and biomechanical influences over the course of individual life. Changes in bones also occur in evolution as functional adaptations to the environment. In this study, we report on the evolution of bone mass increase (BMI) that occurred in the postcranium and skull of extinct aquatic sloths. Although non-pathological BMI in postcranial skeleton has been known in aquatic mammals, we here document general BMI in the skull for the first time...

Background The Draf 3 procedure has been demonstrated to be effective in the treatment of refractory frontal sinus disease. A variety of clinical factors may contribute to the change of frontal neo-ostium (FNO) area after this procedure. Imaging plays a vital role in the evaluation and follow-up after surgery and provides useful prognostic information. Objectives (1) To investigate the influence of local anatomic factors on FNO after a Draf 3 procedure by radiological measurements on imaging software and (2) to explore other predictive factors of FNO restenosis...

Pre-clinical research in rodents provides evidence that the central nervous system (CNS) has functional lymphatic vessels. In-vivo observations in humans, however, are not demonstrated. We here show data on CNS lymphatic drainage to cervical lymph nodes in-vivo by magnetic resonance imaging (MRI) enhanced with an intrathecal contrast agent as a cerebrospinal fluid (CSF) tracer. Standardized MRI of the intracranial compartment and the neck were acquired before and up to 24-48 hours following intrathecal contrast agent administration in 19 individuals...

BACKGROUND: CVST is an important cause of stroke during late pregnancy and in the puerperium, but it is seldom encountered during early pregnancy. We report a case of a 34-year-old woman presenting with convulsive status epilepticus in early pregnancy. METHODS: In this case, the cranial computed tomography detected hemorrhage. Magnetic resonance imaging revealed a bilateral hypointense signal involving the frontal lobes and a hyperintense lesion on the right temporal lobe on T1-weighted imaging, and a large bilateral hyperintense area involving the frontal lobes on T2-weighted and fluid-attenuated inversion recovery imaging...

Delayed pneumocephalus developed in a 9-year-old dog following transfrontal craniotomy and implantation of an experimental local chemotherapy into a partially resected oligodendroglioma, but the animal appeared to be asymptomatic. MRI evidence of increasing intracranial pressure, including progressive ventricular dilatation and compression of periventricular parenchyma, led to the recommendation for exploratory craniotomy. The barrier between the intracranial cavity and frontal sinus was enhanced, and pneumocephalus resolved on MRI at both 1 and 3 months following the repair...

The demand for facial feminization is increasing in transsexual patients. Masculine foreheads present extensive supraorbital bossing with a more acute glabellar angle, whereas female foreheads show softer features. The aim of this article is to describe our surgical technique for fronto-orbital feminization. The mask-lift technique is an upper face-lift. It provides rejuvenation by correcting collapsed features, and fronto-orbital feminization through burring of orbital rims and lateral canthopexies. Depending on the size of the frontal sinus and the thickness of its anterior wall, frontal remodeling is achieved using simple burring or by means of the eggshell technique...
