Abstract:

Maxillary sinus hypoplasia (MSH) is an uncommon abnormality of paranasal sinuses noted in clinical practice. Computed tomography (CT) scan helps in diagnosing the anomaly along with any anatomical variation that may be associated with it. MSH is usually associated with other anomalies like uncinate process hypoplasia. Three types of MSH have been described. Type 1 MSH shows mild maxillary sinus hypoplasia, type 2 shows significant sinus hypoplasia with narrowed infundibular passage and hypoplastic or absent uncinate process, and type 3 is cleft like maxillary sinus hypoplasia with absent uncin

Abstract:

Background: The understanding of the dural venous sinus anatomy and normal anatomical variations is fundamental for appropriate diagnosis of cerebral venous sinus pathology and also for surgical planning and treatment of neurological diseases. Cerebral MRV (Magnetic Resonance Venography) is an exclusive imaging technique for appropriate identification of the normal anatomical variations as well as pathology of the dural venous sinuses. Most of the variations have been detected in the superior sagittal, transverse and sigmoid venous sinuses. Objectives: To identify and determine the frequencies

ABSTRACT Paranasal sinus anatomical anomalies with unknown etiology are common. Paranasal sinus-related diseases are associated with so high rate of morbidities, it becomes essential to identify the structure and pathophysiology of the paranasal sinuses. Computed tomography (CT) is a valuable tool in displaying its anatomy, any anatomic variations and diseases. As paranasal sinus development is a complex and long-lasting process, there are great structural variations between individuals. Maxillary and/or frontal sinus aplasia or hypoplasia are more common than the other types. Several degrees

Objectives: Magnetic resonance venography (MRV) is a widely used non-invasive imaging technique to diagnose cerebral dural venous sinus thrombosis (CVST) and intracranial venous abnormalities. Non-visualization of a dural venous sinus is diagnostic of CVST on MRV. However, there are numerous common variances and technical aberrations on MRV that mimic filling defects and might be confused with CVST, making diagnosis difficult. These include aberrant veins and missing, hypoplastic or asymmetric venous sinuses. In addition, reconstruction artifacts might take the form of flow gaps with various l

Abstract:

Background and objective: The frontal bone contains a pair of air-filled hollow cavities called frontal sinuses, the size, shape and anatomic measurements and dimensions of the frontal sinuses are determined by the degree of its pneumatization. Any disturbance to the sinus during its early development stages could results whether in hypoplasia (underdevelopment) or aplasia (total lack) of the sinus either unilaterally or bilaterally. This study aims to investigate the prevalence of aplasia of the frontal sinus among Kurdish populations of Erbil city, in addition to assessment of the type of ap

Cyclic vomiting syndrome is considered to be a chronic functional disorder, the etiology and pathogenesis of which is currently not well understood, and which is characterized by recurrent attacks of intense nausea and vomiting, and sometimes accompanied by abdominal pain, headaches or migraine. This article is the first to demonstrate a case of a cyclic vomiting syndrome in an adult patient with typical vomiting attacks and revealed during the examination dysfunction of the cerebral venous drainage due to a variant of the cerebral venous system development.

Abstract:

The Dandy–Walker Malformation was first described in 1914 by Dandy and Blackfan and is characterized by hypoplasia of the vermis, pseudocystic fourth ventricle, upward displacement of the tentorium, torcular and lateral sinuses, and anteroposterior enlargement of the posterior fossa. This syndrome commonly manifests as hydrocephalus in children, though rare adult cases have been reported. The literature reveals adult symptomatology including brainstem infarction, psychosis, and neuromuscular disease.

Abstract:

Asthma has been implicated as a driving force in lower airway remodeling; however, its effect on upper airway development has not been studied. Clinical disease, particularly cystic fibrosis (CF), has been associated with anatomical paranasal sinus variation, although the mechanism for these variations remains unclear. The purpose of this study was to determine whether asthma is associated with altered sinus pneumatization. Five hundred ninety-one computed tomography scans, including 303 adolescents (age 13-18) and 288 adults (age > 18), were evaluated using the Assessment of Pneumatization

Abstract Introduction: Maxillary sinuses (MS) are the largest paranasal sinuses (PNSs) and the first to develop in the human body. They lie in close proximity to delicate and vulnerable structures such as orbit, nasal and oral cavities, and pterygopalatine fossae and are readily involved in sinonasal pathology; hence, a thorough knowledge of normal dimensions and frequently encountered variations of MS is of utmost importance to the performing surgeons. Methodology: A study was conducted to see the morphometry and prevalent variations of MS in 101 patients through multidetector computed tomogr

Abstract:

Endovascular embolization is the treatment of choice for carotid-cavernous fistulas (CCFs), but failure to catheterize the cavernous sinus may occur as a result of vessel tortuosity, hypoplasia, or stenosis. In addition to conventional transvenous or transarterial routes, alternative approaches should be considered. The authors present a case in which a straightforward route to the CCF was accessed via transsphenoidal puncture of the cavernous sinus in a neurosurgical hybrid operating suite.This 82-year-old man presented with severe chemosis and proptosis of the right eye.

Binder’s syndrome is an uncommon congenital condition which develops in the first trimester of pregnancy and has characteristic effects on the facial features. Those effects are: arhinoid face, intermaxillary hypoplasia (associated with malocclusion), abnormal position of the nasal bones, nasal mucosa atrophy, anterior nasal spine agenesis and (in most cases) a lack of frontal sinuses. Other deformities, as well as mental retardation, are also possible. Due to the rarity of the disease, there are no treatment trials for these patients.
