Introduction: Cysts of the maxillary sinuses are found in about 10% of the population. There is a necessity to clarify indications for cyst removal taking into account its size. The purpose of the study to clarify the indications for surgical treatment of maxillary sinus cysts as a risk factor for sinus drainage disorders in the development of maxillary sinusitis. Methods and materials: 57 people (92 sinuses) were examined. There were 20 patients (40 sinuses) with acute rhinosinusitis, 22 patients (22 sinuses) with post-augmentation sinusitis, and 15 (30 sinuses) almost healthy individuals among them. Prediction of the cyst size, which can lead to blockage of the maxillary sinus ostium, was performed by direct measurement on coronary sections at the ostiomeatal complex level distance from the surface of the mucoperiosteum in the area of the alveolar recessus to the lower surface of the mucosal surface in the area of the ostium. The obtained data were verified by calculation method taking into account the height of the sinus at the level of the osteomeatal complex, the magnitude of possible mucoperiosteum edema in the alveolar recessus and ostium in acute rhinosinusitis and post-augmentation sinusitis, as well as the magnitude of mucoperiosteum elevation due to sinus lift. Results: It was found that the vertical size of the cyst, which can potentially lead to blockage of the maxillary sinus ostium in acute rhinosinusitis is 21.2±0.8 mm, 14.7±1.1 mm in sinusitis after augmentation of the maxilla, and 28.5±0.7 mm in practically healthy individuals. The calculated values are 18.5 mm, 14.0 mm and 24.5 mm, respectively. In case of acute rhinosinusitis, the distance from the apex of the cyst to the surface of the mucous membrane of the ostiomeatal complex area may decrease by 12.8 mm, and in sinusitis after sinus lift it may decrease by 20.4 mm. Conclusions: To assess the potential of the ostiomeatal complex block by a cyst located in the alveolar recessus in acute rhinosinusitis, its vertical size is really important according to coronary sections of at the ostiomeatal complex level corresponding to the location of 5-6 teeth of the upper jaw. The indication for removal of the cyst of the alveolar recessus of the maxillary sinus, as a factor that may worsen the course of acute rhinosinusitis due to the anastomosis block, is its size exceeding 20 mm, and 15 mm for patients who plan to sinus lift.

Functional endoscopic sinus surgery concentrates primarily on the removal of ostiomeatal complex disease. When required, maxillary sinus ostioplasty is performed. However, surgical widening of a sinus ostium is contrary to common precepts. A study therefore was performed to reevaluate the effects of antrostomies and of intrasinus mucosal removal. Widening of the natural ostium, a separate antrostomy at some distance from the ostium, or radical mucosal removal was performed on 30 rabbits. Fifteen sinuses were used as controls. After 6 to 8 weeks the status of the sinus mucosa and mucociliary clearance was studied. The study confirmed that mucociliary clearance continued toward the natural ostium following inferior antrostomy. Following widening of the natural ostium, mucociliary clearance through the ostium redeveloped in 11 of 18 sinuses but was typically imperfect. There were no cases of ostial closure; however, the incidence of infection was significantly higher in all three experimental groups than in the control group.

AbstractBackground. Functional endoscopic sinus surgery may be indicated when certain anatomic variations impede the normal drainage of the paranasal sinuses through the ostiomeatal complex. We aimed at studying the drainage system of the maxillary sinus which consists of the maxillary infundibulum, the main ostium of the maxillary sinus, the ethmoidal infundibulum and the hiatus semilunaris inferior.Material and methods. The study was performed retrospectively on cone beam computed tomography (CBCT) scans of 60 subjects (N=120 maxillary sinuses). The anatomical pattern of the maxillary sinus drainage was studied on coronal scans.Results. As related to different morphological possibilities in the supero-lateral limit of the maxillary sinus drainage system, five different patterns were defined: in type I (55%) there was no pneumatization in that situs, in type II (18%) there was an infraorbital recess of the maxillary sinus placed above the sinus ostium, in type III (14%) an ethmoidal recess of the maxillary sinus was expanded within the ethmoid bone, above the ethmoidal infundibulum, in type IV (3%) there were Haller cells above the sinus ostium, while in type V (10%) there were non-infraorbital ethmoid air cells above and draining into the ethmoidal infundibulum.Conclusion. It appears that CBCT is a reliable tool to make an anatomical distinction of the variable pattern of pneumatization impeding a normal drainage of the maxillary sinus, between maxillary sinus- and ethmoid-derived air-filled spaces.

Acute rhinosinusitis treatment and prevention is connected to the rational choice of drug dosage form, which will provide the therapeutic effect and the safety of a drug substance or a drug substance complex. Nasal spray with Enisamium Iodide can be used to nasal congestion relief in acute rhinosinusitis because the active substance has an anti-exudative action. Nasal endoscopy could be used in experimental rhinology as a method for direct pathology visualization and for evaluation of the effectiveness of test drugs. Aim: To substantiate Enisamium Iodide (nasal spray) 10 mg/mL effectiveness on maxillary sinus ostium via nasal endoscopy in rabbits with experimental rhinosinusitis. Methods: As a test object was used Enisamium Iodide (nasal spray). As a reference drug, we used BNO-101. Experimental rhinosinusitis was induced in the 1st day. On the 1st , 15th and 25th days in all groups (four groups, six rabbits in each group), we used nasal endoscopy and semi-quantitative assessment to the result objectivity. Results: The total score in the intact control group was 0 (0÷0) on the 15th and 25th days (physiological state). The total score in the control pathology group was 2.0 (2.0÷2.0) and 2.0 (1.0÷2.0) (severe rhinosinusitis) respectively. The total score in Enisamium Iodide treated group was 2.0 (1.0÷2.0) (severe rhinosinusitis) and 0.0 (0.0÷1.0) (physiological state). The total score in BNO-101 treated group was 2.0 (1.0÷2.0) (severe rhinosinusitis) and 1.0 (1.0÷1.0) (mild rhinosinusitis). Conclusions: Nasal endoscopy can be used as an informative visual method. Enisamium Iodide (nasal spray) has been shown a positive effect by endoscopic evaluation of maxillary sinus ostium and exceeded activity of the reference drug.

Background. Endoscopic sinus surgery (ESS) is considered for chronic rhinosinusitis (CRS) after failure of conservative therapy. Objective. The aim of this study was to evaluate endoscopically ostium patency and mucosal recovery after ESS, with either maxillary sinus ostium-preserving or -enlarging techniques. Materials and Methods. Thirty patients with non-polypous CRS were enrolled. Uncinectomy-only and additional middle meatal antrostomy were randomly and single-blindly performed for each side. Pre- and postoperative endoscopic scores were semi-quantitatively determined according to findings in the ostiomeatal complex area. Adhesions, maxillary sinus mucosal swelling, secretions, and ostium obstruction were also endoscopically evaluated. In addition, symptoms were asked and computed tomography scans were taken preoperatively and 9 months postoperatively. Results. At 16 days postoperatively, a better endoscopic score and a less obstructed ostium were found with antrosomy. At 9 months postoperatively the endoscopic score improved significantly and identically with both procedures, however, obstructed ostia and sinus mucosal swelling/secretions were insignificantly more frequently found on the uncinectomy-only side. Endoscopic and radiologic findings of the maxillary sinus mucosa and ostium correlated significantly 9 months postoperatively. Conclusion. There was a good long-term mucosal recovery with both surgical procedures. In terms of early mucosal recovery and ostium patency, antrostomy might be slighly superior.

Introduction: The modern strategy of the treatment of maxillary sinus cysts provides for the surgery in cases of clinically significant cysts, and in other cases – observation. When performing sinuslifting, cysts of the maxillary sinuses are a risk factor for complications. The objective of the study: to increase the effectiveness of treatment of patients with cysts of the maxillary sinus, who are scheduled for dental implantation. Material and Methods: The results of dental implantation in 124 patients with maxillary sinus cysts were studied in order to substantiate the feasibility of removing, before sinuslifting, not only cysts accompanied by complaints but also those located at a distance of 10 mm from the planned implantation site. Results: The frequency of Schneider membrane perforation during sinuslifting was observed in 12.1% of patients. Removing the cysts located within 10 mm from the dental implantation site before sinuslifting reduced the frequency of Schneider membrane perforations by 2.7 times and other complications by 3.7 times. Conclusion: When determining the treatment tactics for patients with maxillary sinus cysts to whom dental implantation is planned, the localization of the cyst in the sinus and its relationship between the ostiomeatal complex and the site of dental implantation should be taken into account. Removal of cysts of the maxillary sinus, located above the site of the planned dental implantation and within 10 mm from it, reduces the frequency of sinuslifting complications.

Mosher said that intranasal ethmoidectomy is the most dangerous and terrifying. He said that in the mid-twentieth century. Endoscopy changed this view significantly. Since the commencement of medication, various endeavours have been made to light up and analyse within the different empty depressions situated inside the body.A hospital-based comparative and correlative study was undertaken with 50 patients. The research assessed the clinicoradiological comparison of obstructive ostiomeatal complex in cases of rhinosinusitis. Majority (28%) patients were 31-40 years in the age group. The 34.2±12.50 years was the mean age of patients.60% patients were males. The most common symptoms were nasal obstruction (80%) followed by headache (76%), nasal discharge (42%), postnasal discharge (40%), sneezing (28%) and epistaxis (20%). Osteomeatal complex and maxillary sinus were the most frequently affected regions seen in 88% of patients. The most common sign is purulent middle meatal discharge in 86% of patients. The next most common sign seen is deviated nasal septum in 46% of the patients. 62% of the patients in our study suffered from chronic rhinosinusitis. Out of 50 cases, 33 cases have septal deviation using DNE. Uncinate attachment to the skull base is seen in 18 (36%) cases each on the right, and 17 (34%) left side in both DNE and CT. In DNE 7 (14%) cases show middle turbinate hypertrophy on the right side.There was statistically significant correlation between Middle turbinate: concha bullosa and Maxillary sinus (r=0.621; p=0.0005), Pneumatiseduncinate and Anterior ethmoids (r=0.452; p=0.0001), Aggernasi and Frontal sinus (r=0.318; p=0.024) and Middle turbinate: paradoxical and Maxillary sinus (r=0.864; p=0.0001). The significance of variations is that they impair the normal drainage pathway, hinder endoscopic access to distal areas and increase the risk of endoscopic mishaps.

Abstract Background The presence of septa increases the risk of Schneiderian membrane perforation during sinus lift procedure, and therefore, the chance of graft failure increases. We present a safe method of managing septa and, in particular, overcoming small and palatally located septa. Methods After the elevation of the flap and the creation of a small bony window positioned anterior to the septum, the Schneiderian membrane is lifted carefully. A thin and narrow osteotome is then placed at the indentation created at the base of the septum, and mobilization of the septum is achieved by gentle malleting. The membrane is again carefully lifted up behind the septum. Results There was one small membrane perforation case in all 16 cases, and none of these patients showed postoperative complications such as implant failure, infection, or maxillary sinusitis. Conclusions This technique is useful for overcoming the problem of maxillary sinus septa hindering the sinus floor elevation procedure, leading to fewer complications.

Introduction. There is an increasing interest in the association between erectile dysfunction (ED) and cardiovascular risk factor. Epicardial adipose tissue (EAT) is associated with insulin resistance, increased cardiometabolic risk, and coronary artery disease. Our aim was to investigate relationships between epicardial fat thickness (EFT) as a cardiometabolic risk factor and erectile dysfunction.Method. We selected 30 erectile dysfunction patients without comorbidities and 30 healthy individuals. IIEF-5 score was applied to all patients, and IIEF-5 score below 22 was considered as erectile dysfunction. EFT was measured by echocardiography.Results. Body mass index (BMI) was higher in ED patients than those without ED (28.19 ± 4.45 kg/m2versus23.84±2.36 kg/m2,P = 0.001, resp.). Waist circumstance (WC) was higher in ED patients than those without ED (106.60±5.90versus87.86 ± 14.51,P = 0.001, resp.). EFT was higher in ED patients compared to non-ED patients (0.49 ± 0.09 cm versus0.45 ± 0.03 cm,P = 0.016, resp.). There was positive correlation among BMI, WC, and EFT. There was negative correlation between EFT and IIEF-5 score (r : -0.632,P = 0.001).Conclusion. EAT, BMI, and WC as cardiometabolic risk factors were higher in erectile dysfunction patients.
