Nasal obstruction (NO) is defined as the subjective perception of discomfort or difficulty in the passage of air through the nostrils. It is a common reason for consultation in primary and specialized care, and it may affect up to 30-40% of the population. It affects the quality of life (it especially disturbs sleep) and lowers work efficiency. The aim of this document is to agree on how to treat NO, establish a methodology for evaluating and diagnosing it, and define an individualized approach to its treatment...

Although the embryology of the posterior cranial fossa can have life altering effects on a patient, a comprehensive review on this topic is difficult to find in the peer-reviewed medical literature. Therefore, this review paper, using standard search engines, seemed timely. The embryology of the posterior cranial fossa is complex and relies on a unique timing of various neurovascular and bony elements. Derailment of these developmental processes can lead to a wide range of malformations such as the Chiari malformations...

OBJECTIVES: Craniofacial sutures are important growth sites for skull development and are sensitive to mechanical stress. In order to determine the role of bone resorption in stress-mediated sutural bone growth, midpalatal suture expansion was performed in mice receiving alendronate, an anti-resorptive bisphosphonate. MATERIALS AND METHODS: The midpalatal sutures of 8-week-old C57BL/6 mice were expanded by orthodontic wires over the period of 2 weeks. Mice with maxillary expansion without drug treatment as well as untreated animals served as controls...

Tuberous-sclerosis-complex (TSC) is associated with a high lifetime risk of severe complications. Clinical manifestations are largely variable and diagnosis is often missed. Sclerotic-bone-lesions (SBL) could represent a potential imaging biomarker for the diagnosis of TSC. In this study, computed tomography (CT) data sets of 49 TSC patients (31 females) were included and compared to an age/sex matched control group. Imaging features of SBLs included frequency, size and location pattern. Sensitivities, specificities and cutoff values for the diagnosis of TSC were established for the skull, thorax, and abdomen/pelvis...

A rare case of a 15-year-old male patient with neuromuscular scoliosis with forced vital capacity (FVC) below 30%, who went through a successful surgery without any pulmonary complications, is reported herein. The patient had obvious asymmetric shoulders and poor exercise tolerance. The Cobb's angle of the main thoracic curve was 62.8°, and FVC in sitting position was 18% of predictive value. After skull traction and pulmonary rehabilitation, the FVC was still below 30%, and he finally went through surgery under this serious condition...

REVIEW
Fabrice Gankam Kengne, Guy Decaux
Hyponatremia is defined by low serum sodium concentration and is the most common electrolyte disorder encountered in clinical practice. Serum sodium is the main determinant of plasma osmolality, which, in turn, affects cell volume. In the presence of low extracellular osmolality, cells will swell if the adaptation mechanisms involved in the cell volume maintenance are inadequate. The most dramatic effects of hyponatremia on the brain are seen when serum sodium concentration decreases in a short period, allowing little or no adaptation...

Massospondylus carinatus is a basal sauropodomorph dinosaur from the early Jurassic Elliot Formation of South Africa. It is one of the best-represented fossil dinosaur taxa, known from hundreds of specimens including at least 13 complete or nearly complete skulls. Surprisingly, the internal cranial anatomy of M. carinatus has never been described using computed tomography (CT) methods. Using CT scans and 3D digital representations, we digitally reconstruct the bones of the facial skeleton, braincase, and palate of a complete, undistorted cranium of M...

A 60-year-old woman with history of multiple myeloma was in remission after stem cell transplant 6 years prior. She was undergoing work-up for headaches that were thought to be secondary to a right mastoiditis seen on magnetic resonance imaging (MRI). On routine eye exam, papilloedema was noted. A lumbar puncture was performed, with elevated opening pressure with normal constituents. She was an atypical age for idiopathic intracranial hypertension, and her mastoiditis raised concern for secondary cerebral venous sinus thrombosis...

OBJECT: Skull base meningiomas carry a non-negligible risk of recurrence. In particular, those arising from the sphenoid wings or middle cranial fossa penetrate into extracranial regions, uncommonly showing massive expansion into the craniofacial regions on recurrence. The role of endoscopic endonasal surgery for those intractable lesions remains unclear. METHODS: We performed endoscopic endonasal craniofacial surgery for 8 recurrent meningiomas invading into the pterygopalatine fossa, infratemporal fossa, nasopharynx, paranasal sinus, or orbit, comprising 2 meningothelial and 1 fibrous meningiomas (WHO grade I), 3 atypical and 1 clear cell meningiomas (grade II), and 1 anaplastic meningioma (grade III)...

BACKGROUND: A few options of extracranial donor vessels exist for utilization in intracranial vascular bypass procedures. To our knowledge, the use of an internal thoracic artery for cerebral revascularization has not been studied previously. Hence, this cadaveric feasibility study was performed. METHODS: The internal thoracic artery was dissected in five adult cadaveric specimens. The proximal diameter, distal diameter, and the length of the vessel were measured and recorded...

With an annual incidence of 5/100,000, meningioma is the most frequent primary tumor of the central nervous system. Risk factors are radiotherapy and hormone intake. Most meningiomas are grade I benign tumors, but up to 15% are atypical and 2% anaplastic according to the WHO 2016 histological criteria. Areas covered: This review details the current standard therapy based on international guidelines and recent literature, and describes new approaches developed to treat refractory cases. First-line treatments are observation and surgery, but adjuvant radiotherapy/radiosurgery is discussed for atypical and indicated for anaplastic meningiomas...

OBJECTIVE: This study adds important information regarding the morphological alterations caused by growth hormone hypersecretion in the skull and craniocervical junction (CCJ). A variably asymmetric skull due to acromegaly coexists with expansion of the paranasal sinuses and multiple Wormian bones. CASE REPORT: A pathologically asymmetric dry skull of a European male, aged 38 years at death, with cranial vault and skull base thickening is described. The extensive paranasal sinus pneumatization caused a generalized thinning of the bony walls...

BACKGROUND: Radionecrosis is a complication of nasopharyngeal carcinoma (NPC) that is difficult to treat. Endoscopic debridement is the first-line treatment for radionecrosis. After debridement, however, either bone or the internal carotid artery is exposed and requires mucosal coverage. OBJECTIVES: This study sought to demonstrate the effectiveness of a nasoseptal flap (NSF) after endoscopic debridement of radionecrosis in the reconstruction of nasopharyngeal or skull base defects...

BACKGROUND: Endoscopic transsphenoidal skull base surgery (ETSS) is now considered the criterion standard approach for resection of pituitary adenomas and other midline anterior skull base lesions. Normal sinonasal structures are resected during ETSS, which raises concerns for nasal morbidity and patient-based outcome. OBJECTIVE: To perform a surgical outcome assessment by examining whether the extent of ETSS approaches affected patient-specific sinonasal quality of life as measured by the 22-item Sino-Nasal Outcome Test (SNOT-22)...
