AIM Intranasal aerosol administration of drugs is widely used by ENT specialists. Although clinical evidence is still lacking, intranasal nebulization appears to be an interesting therapeutic option for local drug delivery, targeting anatomic sites beyond the nasal valve. The sonic nebulizer NL11SN associates a 100Hertz (Hz) sound to the aerosolization to improve deposition in the nasal/paranas...

OBJECTIVE To investigate recanalisation in the first 12 months after cerebral venous thrombosis. METHODS 33 consecutive patients presenting with cerebral venous thrombosis were enrolled in the study. Diagnosis was made by magnetic resonance imaging (MRI) and magnetic resonance venography (MRV) or catheter angiography. Patients were initially treated with intravenous heparin. Warfarin was give...

PURPOSE We report on the evolution in one institution from transarterial embolization for the treatment of dural arteriovenous fistulas of the lateral and sigmoid sinuses to the safer and more durable technique of transvenous endovascular therapy for the majority of these lesions. METHODS Arterial, venous, and combined embolizations were performed for 24 fistulas of the lateral and sigmoid si...

Mittermaier and Marchionini (Zeitschrift f. Hals-NasenOhren-Heilkunde, 1928. B. 20) investigated the state of mucous membranes secretions in acute inflammation paranasal sinuses, found a displacement Pu towards acidic reaction; so, with frontal sinus, Rn 6.63; severe purulent sinusitis Pn 6.4. With transition an process into chronic one, pH also shifts alkalinity; so. polypoidly degenerated muc...

PURPOSE To determine the imaging appearance and frequency with which arachnoid granulations are seen on contrast-enhanced CT and MR studies of the brain. METHODS We retrospectively reviewed 573 contrast-enhanced CT scans and 100 contrast-enhanced MR studies of the brain for the presence of discrete filling defects within the venous sinuses. An anatomic study of the dural sinuses of 29 cadaver...

Objective: A study to evaluate the effectiveness of the use of pre CT checklist in requesting CT paranasal sinuses for managing patients with Chronic Rhinosinusitis (CRS). Place and Duration: CT sinuses performed at Aberdeen Royal Infirmary from 20 Aug 2010 to 3rd Nov 2010 after the introduction of pre CT paranasal sinus request checklist. Methods: Prospective studies of patients undergoing CT ...

affairs which is a cause of great annoyance and distress to the patient, and very often of loss of prestige to the surgeon. Abdominal wounds seem peculiarly prone to the development of sinuses, possibly owing to the fact that it is difficult to apply effective pressure in this situation, there is a greater liability to post-operative oozing and the consequent formation of dead spaces in which o...

The frontal sinuses of bovid mammals display a great deal of diversity, which has been attributed to both phylogenetic and functional influences. In-depth study of the hartebeest (Alcelaphus buselaphus), a large African antelope, reveals a number of previously undescribed details of frontal sinus morphology. In A. buselaphus, the frontal sinuses conform closely to the shape of the frontal bone,...
