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

Objectives: To investigate the incidence of accessory maxillary sinus ostia in superior meatus in patients with clinical and radiological signs of maxillary sinusitis and the association with the development of chronic rhinosinusitis. Design: Retrospective study Setting: Tertiary care hospital Participant: 159 patients examined with paranasal sinus computed tomography scans Main outcome measures: We retrospectively evaluated patients who visited the outpatient department at an academic medical facility between January and April 2020 with a clinical diagnosis of chronic rhinosinusitis. Paranasal sinus axial and coronal computed tomography scans were evaluated for accessory maxillary sinus ostia in superior meatus and confirmed by reconstructed three-dimensional simulation images. The demographic information and incidence of accessory ostia in superior meatus were assessed. The Lund–Mackay score was used to rate chronic rhinosinusitis severity. Analysis of variance was performed to correlate the severity of chronic rhinosinusitis with presenting accessory ostia in superior meatus. Results: Of 159 patients (81 males; 78 females), 41.5% had accessory maxillary sinus ostia in superior meatus. Of these, two-thirds were bilateral and one-third was unilateral. The severity of rhinosinusitis was not correlated with having accessory maxillary sinus ostia in superior meatus, but the presence of accessory ostia was significantly associated with less severe chronic rhinosinusitis (P < 0.001). Conclusions: Accessory maxillary sinus ostia in superior meatus are significantly associated with less severe chronic rhinosinusitis and most cases are bilateral.

Maxillary sinusitis due to dental causes is usually secondary to periodontal disease or periapical infection and is commonly associated with mucosal thickening of the floor of the maxillary antrum. Computed tomography (CT) is currently the modality of choice for evaluating the extent of disease and any predisposing factors in patients with symptoms of chronic maxillary sinusitis, but it is unable to diagnose dental disease reliably. The presence of restorative dentistry is, however, easily seen at CT and is associated with both periapical and periodontal disease. We aimed to determine whether its presence at CT may predispose to maxillary sinusitis, and in particular to focal mucosal thickening of the sinus floor characteristic of dental origin.Three hundred and thirty maxillary sinus CT images in 165 patients were reviewed for the presence of restorative dentistry in the adjacent teeth, focal maxillary sinus floor mucosal thickening, any maxillary sinus disease (including complete opacification, air fluid levels, diffuse mucosal thickening, focal mucosal thickening) and evidence of a rhinogenic aetiology (osteomeatal complex pathology, mucosal thickening in other sinuses).One hundred and ninety two sinuses adjacent to restorative dentistry and 178 sinuses not adjacent to restorative dentistry were analysed. Focal floor thickening both with, and without, evidence of a rhinogenic aetiology, was significantly more common adjacent to restorative dentistry. Maxillary sinus disease overall was no more common adjacent to restorative dentistry.This work demonstrated that the presence of restorative dentistry predisposes to focal mucosal thickening in the floor of the maxillary sinus and its presence should prompt clinical and radiographical assessment to exclude dental disease as a source of chronic maxillary sinusitis.

Background and Objectives: Odontogenic sinusitis is a frequently underestimated pathology with fewer symptoms in patients with periapical lesions, periodontal disease, or iatrogenic foreign bodies in the maxillary sinus. The aim of our study was to determine the correlation between maxillary sinusitis and periapical lesions using cone-beam computed tomography (CBCT) imaging and histological and immunohistochemical investigations. Materials and Methods: A total of 1450 initial patients diagnosed with maxillary sinusitis in the Ear-Nose-Throat (ENT) Department, University of Medicine and Pharmacy “Grigore T. Popa” Iasi, Romania, were treated with anti-inflammatory drugs. Of these, 629 still had unresolved symptomatology and were later referred to the Dental Medicine departments for further investigations. Only 50 subjects with periapical lesions in the premolar/molar maxillary area were included in the present study. All the periapical lesions were observed on CBCT and classified using the Periapical Status Index (PSI) and the mean maxillary sinus mucosa thicknesses (MSMT). The enrolled patients underwent surgical procedures with the excision of periapical lesions. The excised samples were submitted to the histological and immunohistochemical investigations. Results: The 50 patients presented periapical lesions of their maxillary teeth in 328 dental units. There was a higher prevalence of periapical lesions in men than in women (chi-square test). We observed a significant difference between the mean MSMT of individuals with periapical lesions compared to those without (p < 0.01). Mean MSMT was 1.23 mm for teeth without periapical lesions and 3.95 mm for teeth with periapical lesions. The histopathological study identified 50% cases with periapical granulomas, 10% cases with periapical granulomas with cystic potential, and 40% cases as periapical cysts. Immunohistochemical stainings showed that CD4+ helper and CD8+ cytotoxic T lymphocytes, along with CD20+ B lymphocytes and CD68+ macrophages, were diffusely distributed in all periapical cysts and in some periapical granulomas, but CD79α+ plasma cells characterized especially periapical granulomas. Conclusions: The current study observed a significant correlation between CBCT maxillary mucosa thickness and type of periapical lesion. Chronic inflammatory lympho-histiocytic infiltrate predominates in periapical lesions, supporting the idea that lesion progression is determined by a humoral-type (CD20+ and CD79α+ B lymphocytes) but also by a cellular-type (CD4+ and CD8+ T lymphocyte population) immune mechanism.

AbstractBACKGROUND. The relationship between the maxillary sinus floor and the roots of the teeth in the upper arch is essential, especially in the correct diagnosis and treatment of odontogenic maxillary sinusitis. The aim of this study was to determine exactly this distance and to observe the most common teeth situated closely to the maxillary sinus.MATERIAL AND METHODS. The study was performed in 2020, in the ENT Department of “Sfanta Maria” Hospital, and was made based on computed tomography (CT) scans of the sinuses from the clinic’s archive. The image analysis was performed with a radiologic software. For each tooth, from both right and left upper hemiarcade, the distance between the dental root and the bony floor of the maxillary sinus was measured and the average distances were compared.RESULTS. Among the present teeth analysed, those with the closest distance were the 1st M (95.15% on the right side and 96.23% on the left side), then the second molars (96.08% on the right side and 90% on the left side). The 2nd and 3rd PM had a similar percentage of the sinusal approach, which varied between 82% and 86%.CONCLUSION. Knowing these dento-sinusal relationships, there is a win-win situation for both the ENT doctor and the dentist. The paraclinical examination necessary for the analysis of the dento-alveolo-sinusal relation and of the afferent pathology is the imaging one, of choice being the CT and CBCT scans.

Back ground: Nasal cytology has generally been employed as a useful diagnostic tool in the differentiation of rhinopathies. Objective The aim of this study was to assess the extent and diagnostic value of inflammation of nasal and paranasal sinus mucosa in chronic rhinosinusitis patients by employing a combination of nasal brushings and a liquid-based cytological technique. Methods Forty-eight patients with chronic sinusitis and 20 control subjects without any sign of sinusitis undergoing endoscopic surgery, although not all underwent endoscopic sinus surgery, were recruited to the study. Nasal cytology samples were collected from all subjects using nasal brush and processed a liquid-based cytological technique for evaluation of total and differential inflammatory cell counts. Biopsies were also taken from the inferior turbinates from its anterior margin in all subjects and from identical lateral maxillary sinus mucosa in patients with chronic sinusitis during surgery and routinely processed for staining and evaluation of inflammatory cells. Results Total and individual inflammatory cell counts in nasal brushings were significantly correlated with the respective inflammatory cell counts in biopsies obtained from the inferior turbinate (eosinophils: r = .519 and P = .016; neutrophils: r = .540 and P = .012; lymphocytes: r = .540 and P = .011) but not in biopsies obtained from the maxillary sinus. No correlation was observed between the inflammatory cells in biopsies from the inferior turbinate and biopsies from the maxillary sinus. The liquid-based cytological technique showed higher sensitivity (94.1%), specificity (76.9%), and positive predictive value (84.2%) for inflammation in the inferior turbinates than for inflammation in the maxillary sinus (sensitivity = 63.4% and positive predictive value = 63.4%). Conclusion Nasal cytology evaluated by use of nasal brushings processed by a liquid-based cytological technique is likely to have higher diagnostic value for the inflammatory response in noninfectious rhinitis than in chronic rhinosinusitis.

Abstract. The mucoperiostitis and local osteitis are radiological symptoms of the fungal ball of the maxillary sinuses. The condition of the mucoperiosteum and the adjacent bone in the alveolar bay of the maxillary sinus predict the results of dental implantation and subantral augmentation. The endoscopic access to the sinus by the antrostomy in the middle meatus and infraturbinal have been used to avoid excessive tissue injury during the removal of the fungal ball. Aim: To assess the condition of the bone and mucoperiosteum of the maxillary sinus in patients with fungal ball after rhinosurgery by the antrostomy with additional osteoplastic infraturbinal access. Methods and materials: The data of 102 patients who underwent surgery for the fungal ball of the maxillary sinus were analyzed, and subsequently - subantral bone augmentation and dental implantation were performed. In patients of the first group (67 people) - endoscopic intervention was performed by antrostomy in the middle meatus, and in 2nd group (35 people) - additional osteoplastic infraturbinal access was used. Result: Computed tomography data were evaluated before endoscopic sinus surgery and before subantral augmentation. The frequency of signs and severity of osteitis according to Kannedy Osteitis Score, after the intervention did not change significantly, and was established as 0.90 ± 0.07 in patients of group №1 and 0.77 ± 0.08 – group №2. The total frequency of complications with subantral augmentation in the comparison groups was 17.91 ± 4.68% and 17.14 ± 6.37%, respectively. Symptoms of osteitis in patients with fungal ball of the maxillary sinus after endoscopic removal, in the first 4 - 6 months of observation tend to regress, but do not disappear. Conclusions: The incidence of osteitis in computed tomography in patients with maxillary sinuses fungal balls in 4.8 months after endoscopic removal tends to decrease and is 77.61 ± 5.09% when approach through the middle meatus and 74.29 ± 7, 39% in patients with combined infraturbinal approach. The use of additional infraturbinal approach in patients with a fungal ball does not adversely affect the results of subsequent subantral augmentation and dental implantation.

IntroductionChronic sinusitis can be caused by both laryngological and dental factors. The number of odontogenic sinusitis (OS) in last decades is increasing and seems to be underrated. A unique developmental and microbiological factors causing OS require a different therapeutic approach.Material and methodsThis study evaluated tomography examinations of 500 patients with a clinical diagnosis of chronic sinusitis. The patients were referred by laryngologists, neurologists, and maxillofacial surgeons. The scans were reanalyzed in view of the presence of odontogenic and laryngological pathologiesResultsAmong the 500 patients, 19,6% showed no inflammatory changes in the mucosa of the paranasal sinuses. All patient groups had numerous teeth missing, ranging from 27.3% to 33.2%. Most common odontogenic pathologies were periapical changes (28,8%) and the presence of teeth after improper endodontic treatment (24,2%). In the group in question dental implants (0,4%) and maxillary sinus augmentation (2,8%) were a marginal etiological factor.ConclusionsComputed tomography allows a thorough assessment of odontogenic changes. Obstruction of osteomeatal complex does not have direct influence on OS development. 43,2 % of the patients with chronic sinusitis have OS. It can be diagnosed in 50,8% of isolated right, 39,0% of isolated left and 57,8% of bilateral maxillary sinusitis patients. The results of this study can be used by dentists, maxillofacial surgeons and otolaryngologists to improve the standard of diagnosis and treatment in case of chronic odontogenic sinusitis.
