Study on anatomical variations of nose and paranasal sinuses in patients with sinonasal polyposis

Background: Knowledge regarding the sinonasal variations plays an important role in the management of sinonasal diseases. Despite being postulated as one of the risk factors for sinonasal diseases, its role in the pathogenesis of nasal polyp is still unclear. This study was done to determine the prevalence of sinonasal anatomical variations by CT imaging and examine its association with sinonasal polyposis (SNP). Method: A descriptive cross-sectional study was conducted from January, 2019 to January, 2020 at a tertiary care center after receiving ethical approval from the institutional review committee of the hospital. Patients above 17 years of age having sinonasal polyp and not responding to 3-4 weeks of medical treatment were included in the study. Convenience sampling was done. Data were collected and entered in Microsoft excel and analyzed using statistical package for the social sciences version 24.0. Results: Among 72 patients, 86.11% of the patients were found to have anatomical variations of nose and paranasal sinuses with Agger nasi (79.09%) and deviated nasal septum (DNS) (72.5%) being the most common variations noted, 29% of patients were found to have a single variation while multiple variations were seen 70.9% of patients. Conclusions: Our study showed that patients with sinonasal polyps have a higher prevalence of sinonasal anatomical variations and severity of polyp increased with the presence of more than one variation in a patient.

Bacterial contamination of autologous blood in reinfusion in neurosurgery: a phenomenon or a problem?

To analyze safety of blood reinfusion with white blood cell filtration and X-ray irradiation for blood decontamination in neurosurgery. The study included 57 patients with various neurosurgical diseases. We used intraoperative blood reinfusion in all patients considering high predictable risk of major blood loss due to neurosurgical diseases, features of neoplasm topography, anamnesis and examination data. Microbiological examination of autologous blood was carried out at different stages before reinfusion. Bacterial contamination of autologous blood samples was observed in 42% of patients. Enlargement of surgical access to paranasal sinuses in patients with craniofacial lesions poses a potential risk of bacterial contamination of autologous blood. Additional methods of decontamination including white blood cell filtration and X-ray irradiation reduced bacterial load. The above-mentioned methods were less effective for decontamination of microflora not typical for human skin compared to saprophytic ones. There were no postoperative infectious complications. Combination of white blood cell filtration and X-ray irradiation reduces bacterial contamination and increases safety of reinfusion although these methods do not completely free autologous blood from opportunistic microorganisms. Decontamination quality significantly depended on microflora and surgical approach.

The development of paranasal sinuses in patients with cystic fibrosis: sinuses volume analysis

BackgroundCystic fibrosis (CF) is a severe systemic disease that affects many aspects of patients’ lives. It is known that the progression of the disease adversely affects lower and upper airways including the paranasal sinuses. However, its impact on sinus development in the pediatric population is not fully examined. The purpose of this study was to evaluate the development of the paranasal sinuses in a pediatric population with CF and compare it to a control group consisting of healthy children.MethodsThe results of computed tomography (CT) scans of children with the disease and the control group were evaluated. The study included 114 CT images of children in the study group and 126 images of healthy children aged 0–18 years. The volumes of maxillary, frontal, and sphenoid sinuses were analyzed. The obtained results were compared with those of the control group and analyzed statistically.ResultsThe volume and the development of the paranasal sinuses in both groups increased with age, but statistically significant differences were found between the study and the control group.ConclusionsThe obtained results provide valuable knowledge regarding the impact of the CF on sinuses development. Also, they may be important in understanding the progression of the disease and its influence on the quality and length of life of patients. The results may contribute to enhanced diagnostics and have implications for improving therapy for patients with chronic sinusitis associated with CF.

Sinonasal and Orbital Imaging Findings in COVID-Associated Rhino-Orbito-Cerebral Mucormycosis During the Second Wave of COVID-19: A Retrospective Cohort Study in a Tertiary Hospital in Central India.

Background Mucormycosis is a consequence of the angioinvasive disease caused by filamentous fungi that belong to the order Mucorales, particularly Mucor, Rhizopus, and Rhizomucor. Rhizopus oryzae is the most prevalent form. The invading hyphae lead to damage of blood vessels leading to thrombosis and consequent tissue necrosis. The incidence of this disease entity witnessed a significant rise during the second wave of the coronavirus disease 2019 (COVID-19) pandemic. Timely diagnosis and prompt treatment are crucial to diminish both the mortality and morbidity associated with this disease. Imaging plays a pivotal role in diagnosing the ailment, evaluating its extent, identifying complications such as thrombosis, and facilitating surgical planning. It demonstrates exceptional sensitivity in detecting the disease at its early stages, often before symptoms manifest. Due to the angioinvasive nature of Mucor, early detection assumes utmost importance as it necessitates intensive antifungal therapy and the removal of devitalized tissue through debridement. Methodology We conducted a retrospective cohort study to analyze computed tomography (CT) imaging findings in patients with COVID-associated rhino-orbito-cerebral mucormycosis (ROCM) confirmed by histopathological examination. We compared these findings with CT findings of the nose and paranasal sinuses in patients without mucor following COVID-19 sinusitis (non-ROCM). Results All 16 cases in the non-ROCM group were in stage 1 disease. In contrast, in the ROCM group, three patients had stage 1 disease, five patients had stage 2 disease, and 10 patients had stage 3 disease (p = 0.0001). The pterygopalatine fossa was significantly affected in 10 of 18 ROCM patients and in none of the non-ROCM patients. Conclusions Imaging plays a crucial role in the early detection of mucormycosis. It assists treating physicians in initiating prompt and aggressive treatment, thereby improving the prognosis of this frequently fatal disease.

Combined Radiological and Endoscopic Evaluation of Sino Nasal Anatomical Variations in Patients of Chronic Rhinosinusitis: A North Indian Study.

To determine the prevalence of anatomical variations of nasal cavity and paranasal sinuses of patients with chronic rhinosinusitis (CRS) on CT scan imaging. To correlate the Anatomical variations with the extent of CRS. 100 patients attending the ENT outpatient department with clinically diagnosed CRS were selected for study based on inclusion and exclusion criteria. Patients were subjected to CT scan and diagnostic nasal endoscopy. The correlation of anatomical variation with severity of CRS based on radiological score and endoscopic score was observed. Deviated nasal septum was the most common anatomical variation observed in 71% cases. Followed by Agger nasi (68%), concha bullosa (55%), Onodi cell (25%), Haller cell (14%), frontal sinus hypoplasia (2%) and uncinate bulla (1%) respectively. Statistically significant relationship of radiological score with left side Bullous Concha Bullosa and highly statistically significant relationship with Haller Cell was observed. While statistically significant relationship between Deviated Nasal Septum on left side with endoscopic score was also observed. Correlation of anatomical variation with CRS concludes on the notethat some variations cause impaired sinus drainage and ventilation leading to recurrent sinusitis. Also, incidence of these variations was comparable to other studies done in asymptomatic population therefore, simply detection of a solitary anatomical variant itself does not determine predisposition to disease or the pathogenesis of the CRS and that we should have a critical look out for these anatomical variations from point of view of surgical management.

Computed tomography findings of paranasal sinuses in patients with eosinophilic granulomatosis with polyangiitis: Comparison with other eosinophilic sinus diseases and clinical relevance of their severity

BackgroundAlthough paranasal sinuses are one of the most representative organs affected by eosinophilic granulomatosis with polyangiitis (EGPA), they have not been studied sufficiently. The aim of this study was to compare computed tomography (CT) findings in paranasal sinuses of EGPA with those of other eosinophilic sinus diseases and elucidate the clinical relevance of their severity. MethodsCT findings of paranasal sinuses in EGPA patients prior to therapeutic intervention (n = 30) were evaluated using the Lund–Mackay staging (LMS) system and compared with those of three control diseases [(NSAID-exacerbated respiratory disease (N-ERD), aspirin-tolerant asthma, and eosinophilic chronic rhinosinusitis without asthma (ECRS)]. We divided EGPA patients into three groups based on their LMS scores and examined their association with disease manifestation. ResultsTotal scores of the LMS system in EGPA were significantly lower than those of N-ERD and ECRS without asthma. There was a large variation in total LMS scores in EGPA, suggesting considerable heterogeneity of their sinus lesions. Although EGPA with low LMS system scores showed only minor findings in maxillary and anterior ethmoid regions, those with high LMS system scores were characterized by high scores in the ostiomeatal complex. However, the frequencies of patients with a Five-Factor Score ≥2 and with cardiac involvement were significantly higher for EGPA with low LMS system scores. ConclusionsAlthough paranasal sinus lesions in EGPA were less severe than those of other eosinophilic sinus diseases, their milder CT findings may be associated with a higher frequency of extra-respiratory organ involvement.

Association between mucous retention cyst of paranasal sinuses and nasal septum deviation

IntroductionMucous Retention cyst is a mass of fluid containing serous or mucous. Nasal septum deviation (NSD) is a condition that may cause sinusitis in severe cases. In addition, the frequency of maxillary sinus retention cysts is higher in patients with sinusitis than in patients without sinusitis. This study aimed to evaluate the retention cyst in the paranasal sinuses in patients with septum deviation compared with those without NSD. Materials and methodsThis observational study was performed by simple random sampling from CBCT scans of patients over 18 years’ old those referred to the radiology department of Isfahan Dental School (Khorasgan) 100 patients with NSD and 100 patients with no NSD. Data were analyzed by independent samples t-test, Mann-Whitney U test, Chi-square, and Fisher exact tests. ResultsMucous retention cysts were observed in 5% of patients without NSD and 19% of patients with NSD (p = 0.002). Also, the number of cyst retention was significantly higher in patients with NSD (p = 0.002) but there was no significant relationship between cyst side and nasal deviation in patients with NSD (p = 1.00). ConclusionThere was a significant relationship between the occurrence of mucous retention cysts and NSD and the number of cysts in the group with greater deviation.

Virtual rhinomanometry based on computed tomography of the paranasal sinuses in patients with nasal septum deviation a pilot study.

The aim of the study was to compare the flow disturbances in computational fluid dynamics (CFD) technique based on computed tomography (CT) to the results of active anterior rhinomanometry (RMM), in patients with nasal septum deviation (NSD). In 24 patients with NSD, RMM and CT of the paranasal sinuses were performed as a part of typical clinical management. For each patient, 3D models of air-filled spaces in the nasal cavity were created, based on CT images, and air flow simulations during inhalation were performed using CFD technique. Correlations between RMM, both before and after anemization, during inspiration, and CFD were tested, independently for the left and right side. The obtained correlation coefficients for the comparison of flow in RMM during inspiration and in CFD during simulated inspiration were: before anemization 0.46 for the left side and 0.52 for the right side, after anemization 0.65 for the left side and 0.61 for the right side (p < 0.05). Moderate correlation was found between the results of real and virtual rhinomanometry, with higher correlation coefficients obtained after anemization, compared to the values before anemization.

Rhinological Status of Patients with Nasolacrimal Duct Obstruction

Introduction Studying the state of the nasal cavity and its sinuses and the morphometric parameters of the inferior nasal conchae, as well as a comparative analysis of obtained values in patients with primary (PANDO) and secondary acquired nasolacrimal duct obstruction (SALDO), is relevant. Objective To study the rhinological status of patients with PANDO) and SALDO). Methods The present study was based on the results of computed tomography (CT) dacryocystography in patients with PANDO ( n = 45) and SALDO due to exposure to radioactive iodine ( n = 14). The control group included CT images of paranasal sinuses in patients with no pathology ( n = 49). Rhinological status according to the Newman and Lund-Mackay scales and volume of the inferior nasal conchae were assessed. Statistical processing included nonparametric statistics methods; χ 2 Pearson test; and the Spearman rank correlation method. Results The difference in values of the Newman and Lund-Mackay scales for the tested groups was significant. A significant difference in scores by the Newman scale was revealed when comparing the results of patients with SALDO and PANDO. Comparing the scores by the Lund-Mackay scale, a significant difference was found between the results of patients with SALDO and PANDO and between the results of patients with PANDO and the control group. Conclusion It was demonstrated that the rhinological status of patients with PANDO was worse than that of patients with SALDO and of subjects in the control group. No connection was found between the volume of the inferior nasal conchae and the development of lacrimal duct obstruction.

Clinical Presentations of Patients with Chronic Rhinosinusitis

Purpose of Review: Chronic rhinosinusitis (CRS) is denoted as the symptomatic inflammations of sin nasal mucosa persists for ≥12 weeks. The purpose of this study was to review the recent literatures for digging out a clear concept on the clinical presentations of patients with chronic rhinosinusitis and assess the potentialities of the features.
 Recent Findings: According to the findings, descriptions and discussions of several recent studies it was observed that, a package of clinical features and presentations are associated with chronic rhinosinusitis. Some are major and some are minor potentials. The frequencies and severities of symptoms and features are directly dependent on the duration of that disease.
 Summary: Basically, rhinosinusitis or CRS is an inflammatory and infectious disease which affects the nasal cavities as well as the paranasal sinuses of patients. Rhinosinusitis with polyps is more common in male than that in female. There are many possible clinical features of CRS. But as per the frequencies, duration and effects nasal congestion, nasal discharge (Anterior/posterior nasal drip), pain/pressure on the face, impaired ability to smell (Hyposmia/anosmia), dizziness, fever and cough are the most common clinical features of chronic rhinosinusitis.

Morphofunctional State of the Maxillary Sinus Mucosa in Patients After Endoscopic Infundibulotomy

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.

Correlation between the Opacification Degree of Paranasal Sinuses on CT, Clinical Symptoms and Anatomical Variations of the Nose and Paranasal Sinuses in Patients with Chronic Rhinosinusitis.

Objectives: This study aimed to evaluate the correlation between the opacification degree of the paranasal sinuses on computed tomography (CT) with clinical symptoms, and anatomical variations of the nose and paranasal sinuses in patients with chronic rhinosinusitis (CRS). Materials and Methods: This descriptive prospective study evaluated 100 patients (60 males and 40 females), who were diagnosed with CRS by ENT specialists according to the clinical findings, and were scheduled for a CT scan. The patients were requested to express the severity of their symptoms using a visual analog scale. The CT scans of the paranasal sinuses were assessed for the presence of anatomical variations and scored using the modified Lund-Mackay scoring system for the opacification degree of each sinus. The correlations between the anatomical variations and sinusitis, and also between the severity of symptoms/disease severity and CT scores were statistically analyzed. P<0.05 was considered statistically significant. Results: The most common symptoms were purulent (discolored) nasal drainage and nasal obstruction. Septal deviation was the most common anatomical variation. The maxillary and anterior ethmoid sinuses were the most commonly involved areas. The Spearman’s correlation coefficient showed a significant correlation between the sinus involvement and some of the evaluated symptoms, as well as certain types of anatomical variations (P<0.05). Conclusion: Some specific anatomical variations of the paranasal sinuses may predispose them to sinusitis. The CT scan score can predict the severity of many symptoms such as purulent (discolored) nasal drainage, nasal obstruction, hyposmia/anosmia, halitosis, cough, and fatigue, among the other symptoms of CRS.

Features of the inflammatory process of the nasal mucous membrane and paranasal sinuses in patients with chronic rhinosinusitis with nasal polyps

Objectives to assess the features of the inflammatory process of the nasal mucous membrane and sinuses in patients with сhronic rhinosinusitis with nasal polyps (CRSwNP).&#x0D; Material and methods. We analyzed the results of examination of 44 patients with CRSwNP. The objects of investigation were smears-reprints from the mucous membrane of the middle turbinate (rhinocytograms) and the intensity of the extracellular peroxidase activity of the lavage fluids of the maxillary sinuses. The data obtained were processed using the Statistica 8.0 software.&#x0D; Results. When analyzing rhinocytograms of the mucous membrane of the middle turbinates, the epithelial type of rhinocytogram was most often detected in 65.9% of cases (epithelial cells more than 50%); the eosinophilic type in 22.7% (eosinophils more than 1%) and smears with mast cells in 4.6% of cases; the neutrophilic type was less frequent (neutrophils more than 50%) 6.8% of cases. In 34.1% of patients, the cells of the columnar epithelium had pronounced changes in the cytoplasm (vacuolization and enzymatic activity); and in 38.6% of cases the gross pathology was recorded directly in the nucleus of the cells (nucleoli, granules, destruction of the nucleus). The revealed pathology of the cell nucleus suggests the viral etiology of the development of productive inflammation in the nasal cavity and sinuses In the lavage fluids of the maxillary sinuses, a high intensity of extracellular peroxidase activity was recorded (1777.9132.4 a.u. compared to 1225.0190.9 a.u. in patients with chronic purulent rhinosinusitis and 1245.0362.3 a.u. in patients with purulent-polypous rhinosinusitis).&#x0D; Conclusion. Chronic rhinosinusitis with nasal polyps is accompanied by a pronounced inflammatory process of the nasal mucous membrane and paranasal sinuses in the form of structural and functional changes in the cells of the columnar epithelium and a high intensity of extracellular peroxidase activity. The epithelial nucleus damage (the presence of nucleoli, granules, destruction of the nucleus) suggests a viral nature with the development of productive inflammation in the nasal cavity and sinuses.

The Diagnostic Value of the Leukocyte Shift Index in Purulent-Septic Rhinosinusogenic Complications in Children

The aim of this study was to investigate the diagnostic value of the leukocyte shift index (LSI) in inflammatory pathology of the paranasal sinuses (PNS) with the rhinosinusogenic orbital complications (RSOC) in pediatric patients. Methods and Results: The study involved 50 patients (26 boys and 24 girls) with diseases of the PNS and RSOC (reactive edema of the eyelids, orbital tissue, and purulent-septic complications of the eyelids and orbit) aged from 1 to 17 years (mean age of 6.66±0.63 years). Group 1 included 29 patients (16 boys and 13 girls) with reactive edema of the eyelids and orbital tissue. Group 2 included 21 patients (10 boys and 11 girls) with purulent-septic RSOC. As a marker for determining the activity of the inflammatory process and the disorders of the immunological reactivity of the body, LSI (leukocyte shift index) was calculated. In general, the LSI value was 1.61±0.21 in Group 1 and 3.45±0.49 in Group 2 (P=0.001). Among patients aged between 3 and 12 years, the LSI was 1.66±0.30 in Group 1 and 3.93±0.79 in Group 2 (P=0.012). The results obtained indicate that LSI can be used to predict purulent-septic RSOC in inflammatory diseases of PNS in patients aged between 3 and 12 years. LSI values from 1.36 to 1.96 may predict the development of reactive edema of the eyelids and orbital tissue; from 3.14 to 4.72 - the development of purulent-septic complications of the eyelids and orbit. Conclusion: The results obtained can be useful in predicting the clinical course of the RSOC in inflammatory pathology of PNS in patients in the age group of 3-12 years.

Increased Inflammatory Markers Detected in Nasal Lavage Correlate with Paranasal Sinus Abnormalities at MRI in Adolescent Patients with Cystic Fibrosis.

Chronic rhinosinusitis (CRS) is a characteristic feature of cystic fibrosis (CF) multiorgan disease and develops early in the life of patients with CF. The study aimed to correlate the inflammatory markers and the presence of structural abnormalities detected by MRI in the paranasal sinuses of patients with CF. Methods: Nasal lavage and MRI of the paranasal sinuses was performed in a cohort of 30 CF patients (median age 14 y; range 7–20 y). Morphological abnormalities characteristic of CF were evaluated with a dedicated CRS MRI scoring system and correlated with different inflammation parameters measured in nasal lavage. Inflammation of the paranasal sinuses was positively associated with structural abnormalities in MRI. The concentration of the pro-inflammatory markers neutrophil elastase (NE) and the neutrophil elastase/alpha1-antitrypsin (NE/A1AT) complex correlated significantly with CRS-MRI sum score (p < 0.05, r = 0.416 and p < 0.05, r = 0.366, respectively). S. aureus infection was associated with the increased pro-inflammatory cytokine activity of IL-6 and IL-8, and increased levels of NE/A1AT complex in our patients (p < 0.05, respectively). CRS-MRI sum score and individual sinus MRI scores were positively associated with inflammatory activity as a sign of CRS pathology present in CF.

Лікувальна тактика при грибковому тілі верхньощелепового синусу у пацієнтів із запланованою дентальною імплантацією

The fungal ball is the most common clinical form of fungal etiology sinusitis. The main method of treatment of patients with this pathology is surgery. Achieving complete removal of the fungal body is important, especially in patients who will have planned dental implantation. Among the accesses to the maxillary sinus in cases of the fungal body of the sinus, the most common one is through the middle meatus, but it does not provide visual control of the anterior parts of the sinus during the intervention. The use of modified infraturbinal access provides better opportunities for examination of the anterior parts of the maxillary sinus. The purpose of the study is to increase the effectiveness of surgical treatment of patients with fungal bodies of the maxillary sinus by optimizing access during endoscopic endonasal intervention. Materials and methods. The data of 113 patients with fungal ball of maxillary sinuses who underwent sinusotomy in preparation for dental implantation were analyzed. Cone beam computed tomography of paranasal sinuses of patients were performed twice – before functional endoscopic sinus surgery and before subantral augmentation of the maxillary bone. Group 1 included 78 patients to whom the fungal balls were removed from the sinus through the middle nasal meatus, group 2 – 35 patients to whom, in cases when it was impossible to visually confirm the completeness of removal of the fungal ball from the anterior area of the sinus, an additional infraturbinal approach was performed in our modification. Results and discussion. According to tomography before rhinosurgery it was established that "blackout" of more than 60% of the sinus space is observed in 50.5% of patients with fungal bodies, with the vast majority of patients (88.1%) fungal bodies in the maxillary sinus are located in its lower parts and spread forward from the nasolacrimal canal level. During sinus rehabilitation, the need for additional infraturbinal access arose in 5 (14.3%) patients of the second group. As a result of its performance in all 5 operated patients polyposis-altered tissues were found in "blind zones" and in 2 (5.7%) – there were also remains of a fungal body. Residual fungal bodies in the maxillary sinus were detected in 3 (3.9% CI 95% – 0.01; 11.6) patients of the first group, and were not observed in the second group. All cases of residual fungal masses in the sinus were not accompanied by specific complaints. A revision of sinusitis with fungal masses removing was performed on 3 patients due to the appearance of residual fungal bodies by preformed antrostomy with local anesthesia. Conclusion. Anthrostomy using additional endoscopic infraturbinal access when removing the fungal body from the lower anterior maxillary sinus is the optimal combined access that allows maximum visualization of the maxillary sinus and avoid recurrence of the disease
