The One

The one of the most informative method of preoperative diagnosis of fungal paranasal sinuses is computed tomography. The radiological marker that allows to identify chronic sinusitis of fungal origin is an eclipse with hyperintensive inclusions. The sensitivity of this criterion for fungal ball is about 80%. In addition, a sign of recalcitrant chronic sinusitis is the presence of reactive changes in the bone wall of the sinus – "osteitis". The purpose of the work was to study the frequency of radiological signs of osteitis and areas of increased radiological density in the maxillary sinuses of the patients with chronic sinusitis of fungal and non-fungal etiology, to clarify the diagnostic significance of these symptoms in the differential diagnostics. Material and methods. The results of a retrospective study of computer tomography data of 60 people with chronic rhinosinusitis (intraoperative was verified fungal ball in the maxillary sinus space of 30 patients, other 30 patient had no signs of fungal etiology). Results and discussion. In patients with chronic rhinosinusitis of non-fungal nature, hyperintensive inclusions in the sinus were found in 13.3%, and signs of osteitis were detected in 36.7%, which was significantly less common than in patients with fungal processes, 83.3% and 80,0% respectively (p <0,05). The presence of both of the radiological symptoms was observed in 63.3% of patients from the group of chronic rhinosinusitis in the presence of a fungal body in the space of the sinus and in 6.7% of cases the chronic rhinosinusitis of non-fungal etiology. The severity of osteitis according to KOS, in patients with a fungal body in the sinus was 0.71 ± 0.15 points, and 0.55 ± 0.2 points in patients without a fungus. The pathogenesis of osteitis in the cases of sinusitis with fungal origin is a violation of bone trophism, which develops due to periostitis after the influence of biologically active substances secreted by the fungus. The increase of radiation density in areas of osteitis indicates the predominance of osteogenesis over osteolysis in the inflammatory focus of the bone wall of the maxillary sinus. Conclusion. The frequency of detecting radiological signs of osteitis in patients with chronic rhinosinusitis of the maxillary sinus with fungal bodies was 80%, that was comparable to the frequency of detecting hyperintense inclusions in the lumen of the sinus in these patients (83.3%), and was significantly more than in patients with chronic sinusitis nonfungal etiology. The presence of radiological signs of osteitis of the bone wall of the maxillary sinus in computed tomography should be regarded as an additional symptom in the differential diagnosis of maxillary sinusitis of fungal origin

The work carried out made it possible to substantiate the need to apply a method for studying the frequency of beating of cilia of the mucous membrane of the nasal cavity and paranasal sinuses in patients with chronic rhinosinusitis when choosing treatment tactics in an ENT hospital. Analysis of the study of data on the functional and morphological state of the mucous membrane of the nasal cavity and maxillary sinus allows us to judge the severity of the pathological process before surgery, which is the fundamental factor in the algorithm for the treatment of chronic rhinosinusitis.

Sinus Ostium

Chronic maxillary sinusitis may present as atelectasis of the sinus with changes to surrounding structures. Several mechanisms have been proposed for this problem. Chronic obstruction of the sinus ostium, with resultant retention of secretions and osteitic bone resorption, may account for these changes. Enophthalmos is one manifestation that may require corrective treatment. Titanium micromesh reconstruction of the orbital floor, with or without onlay concha cartilage, has reliably resolved the enophthalmos. Reconstruction of the orbital floor and ventilation of the obstructed sinus ostium may be carried out relatively safely in a single operation. The standard endoscopic technique of uncinate removal and middle meatal antrostomy should be modified to prevent orbital penetration. This report reviews our series of 6 patients with this problem, as well as a comprehensive review of the literature. Recommendations for management of both the obstruction and the secondary orbital manifestations are presented.

Sinus Ostium

The effect of topical oxymetazoline hydrochloride on the blood flow of the nasal and sinus mucosa of the rabbit was measured by laser-Doppler flowmetry. Oxymetazoline, the active component in clinically used nose drops, induced a dose-dependent decrease of the nasal mucosal blood flow. This effect has previously been shown in humans and suggests the presence of α2–adrenoceptors in the nasal mucosa of the rabbit. Doses of oxymetazoline used clinically in humans induced a 50% reduction of blood flow in rabbits. Rhythmic variations in blood flow were seen in 30% of the rabbits after administration of oxymetazoline. Additionally, oxymetazoline induced a dose-dependent decrease of the mucosal blood flow in the maxillary sinus when the drug was applied in the nose. A vasoconstricting effect of oxymetazoline on the arteries penetrating the maxillary sinus ostium is a possible explanation. This can have positive as well as negative consequences on acute sinus infections.
