BACKGROUND: Although the term paraclival carotid pervades recent skull base literature, no clear consensus exists regarding boundaries or anatomical segments. OBJECTIVE: To reconcile various internal carotid artery (ICA) nomenclatures for transcranial and endoscopic-endonasal perspectives, we reexamined the transition between lacerum (C3) and cavernous (C4) segments using a C1-C7 segments schema. In this cadaveric study, we obtained a 360°-circumferential view integrating histological, microsurgical, endoscopic, and neuroradiological analyses of this C3-C4 region and identified a distinct transitional segment...

A 24-year-old man was admitted to our Otolaryngology Department following a head and neck CT scan performed for cranial trauma that showed a bulky neoformation in the right parapharyngeal space. Magnetic resonance imaging confirmed the presence of an oval formation with sharp margins and colliquative areas of necrosis involving the right parapharyngeal space. The mass was completely excised by a latero-cervical approach. Based on histological features and immunohistochemical analysis, a diagnosis of embryonal rhabdomyosarcoma of the parapharyngeal space was made...

The aim of this study was the evaluation of three localizations for the implantation of a semi-implantable transcutaneous bone conduction device after previous mastoid surgery. This is a retrospective review of electronic datasets of cranial computed tomography studies. The study setting is one tertiary referral center and included 52 consecutive adult patients (60 temporal bones) with a history of mastoid surgery. The intervention was virtual placement of the device with a planning software within the remaining mastoid as well as dorsal of the sigmoid sinus and caudal of the transverse sinus (retrosigmoidal localization) and dorsocranial of the parietomastoid suture and cranial of the transverse sinus (parietal localization)...

PURPOSE: Complete visualization of certain acetabular fractures of posterior wall or column with cranial extension involving superior dome from standard surgical exposures is a challenge. Osteotomy of the greater trochanter has been used to enhance fracture visualization, especially the dome, in posterior and lateral exposures of the acetabulum. It also decreases the need for excessive muscle retraction. The purpose of the study was to investigate the outcome associated with trochanteric flip osteotomy in the management of certain acetabulum fractures...

The climate of northeastern Europe is likely to resemble in many ways Late Pleistocene periglacial conditions in Europe, but there have been relatively few studies exploring the association between climate and morphology in the mid-face of modern northeastern European populations. To fill this gap, we sampled 540 male skulls from 22 European and Near Eastern groups, including 314 skulls from 11 populations from northeastern Europe, to test for possible climate-morphology association at the continental scale...

Encephalocele is defined as protrusion of cranial contents beyond the normal confines of the skull. Although most encephalocele cases have a congenital etiology, fractures of the skull base can cause traumatic encephalocele. In most encephalocele cases, the bone defect presents reduced dimensions and the endoscopic treatment is generally performed to reconstruct the area using mucosal and/or fat grafts. This article sought to report on a rare case of traumatic encephalocele associated with an extensive defect of the anterior skull base...

The simultaneous evaluation of cerebral hemodynamics and the light scattering properties of in vivo rat brain tissue is demonstrated using a conventional multispectral diffuse reflectance imaging system. This system is constructed from a broadband white light source, a motorized filter wheel with a set of narrowband interference filters, a light guide, a collecting lens, a video zoom lens, and a monochromatic charged-coupled device (CCD) camera. An ellipsoidal cranial window is made in the skull bone of a rat under isoflurane anesthesia to capture in vivo multispectral diffuse reflectance images of the cortical surface...

Chiari malformation type I (CMI) is a congenital abnormality of the cranio-cerebral junction with an estimated incidence of 1 in 1280. CMI is characterized by underdevelopment of the occipital bone and posterior fossa (PF) and consequent cerebellar tonsil herniation. The presence for a genetic basis to CMI is supported by many lines of evidence. The cellular and molecular mechanisms leading to CM1 are poorly understood. The occipital bone formation is dependent on complex interactions between genes and molecules with pathologies resulting from disruption of this delicate process...

BACKGROUND: Primate neurobiologists use chronically implanted devices such as pedestals for head stabilization and chambers to gain access to the brain and study its activity. Such implants are skull-mounted, and made from a hard, durable material, such as titanium. NEW METHOD: Here we present a low-cost method of creating customized 3D-printed cranial implants that are tailored to the anatomy of individual animals. We performed pre-surgical computed tomography (CT) and magnetic resonance (MR) scans to generate three-dimensional (3D) models of the skull and brain...

BACKGROUNDS: Irradiation of the hippocampus plays a role in neurocognitive toxicity. Its delineation is complex and in practice different head position can vary hippocampus morphology on axial images; so atlas in a single standard position can result ineffective to describe different hippocampal morphologies in different head set-up. The purpose of our study was to develop a guide based on magnetic resonance imaging for hippocampus delineation in three different head set-ups. MATERIALS AND METHODS: Three patients were selected to elaborate our guide...

The restless endeavors revealing the molecular pathways underlying many neurodegenerative diseases and brain tumors have paved the way for the introduction of the selective exogenous gene-based therapeutics. The implicated active biomolecules encompass mainly negatively-charged nucleic acids ranging from DNA, mRNA, non-coding RNAs (small-interfering RNA, siRNA, and microRNA, miRNA), to antisense oligonucleotides. They selectively interfere with the genes translational and/or transcriptional processes. Although many reviews previously addressed brain targeting, a thorough correlation between the molecular properties of these biomacromolecules, the nature of blood brain barrier (BBB) in the accompanying pathological condition, the intracellular targets, as well as the design of the delivery system which will transport the bioactive cargo to the target cells attempting efficient delivery to the active sites in the brain will be appraised...
