Sinusitis

We aim to provide an updated and comprehensive review of the current literature on the clinical profile and treatment options of CSBO caused by sinusitis. Three databases, Pubmed, Embase and Scopus, were searched from inception until 2 October 2022. Titles and abstracts were used for the first stage of study selection; subsequently, full texts were screened for final inclusion. Nine studies were included, with eight case reports and one case series. Patients ranged between 33 and 75 years old, with four females and four males total in the case reports. In the case series, there were 14 patients with a mean age of 62 years old. Patients with CSBO secondary to sinusitis often present with non-specific symptoms which may mimic other pathologies of the head and neck. A high index of suspicion for CSBO is important in the presence of an unremitting headache or cranial nerve palsy. Treatment options include culture-directed long-term antibiotics and surgery. The role of surgery in these patients, however, needs to be investigated more thoroughly. We believe that more large-cohort observational studies assessing the association between sinusitis and CSBO should be performed to further analyze and evaluate this topic. Full article

Nasal polyposis is defined as a Th2-driven chronic inflammation of the nose and sinus with polyps visible in the nasal fossae. It is a prevalent disease with a significant impact on health-related quality of life (HRQL). Allergies, allergic rhinitis, asthma, and aspirin intolerance are frequently associated. The management is individual. The first line of treatment is long-term treatment with intranasal corticosteroids. Oral corticosteroids should be used with caution. When the medical treatment fails, the patient is eligible for sinus surgery, which usually consists of a complete sphenoethmoidectomy. In the case of symptomatic recurrence after both medical and surgical treatment, biologics are currently a very promising treatment effective on all respiratory tracts. Dupilumab is considered in the literature to be the molecule of choice. However, besides the international guidelines published by EPOS and Euforea, the molecule prescribed depends also on its availability in each country and the criteria edited by the health authorities to receive reimbursement. Traditional medical treatment remains necessary as a complement to biologics. At the moment, there is no consensus on when the medical treatment can be stopped. Full article

Although technical causes of endoscopic sinus surgery (ESS) failure have long been reported, we were curious about the quality of contemporary sinus surgery. The electronic health database of Mayo Clinic, Arizona was scrutinized to identify adult patients with diffuse chronic rhinosinusitis (CRS) who underwent revision ESS between January 2019 and September 2023 with a history of bilateral full-house ESS. Anatomical features on preoperative radiology and intraoperative endoscopy were cataloged: residual uncinate tissue, maxillary antrostomy with a non-incorporated natural os, residual ethmoidal septations (three septations > 3 mm), and inadequate sphenoid osteotomy (os size < 6 mm). Sixty-nine subjects were identified. A deviated nasal septum was present in 53.6%. Residual uncinate tissue was noted in 50.7% of patients associated with missed natural maxillary os in 39.13% of antrostomies. An inadequate os diameter was noted in 63.8% of sphenoidotomies. Significant residual septations were seen in posterior ethmoidal cells in 66.7% and anterior ethmoidal cells in 62.3% of patients. Residual frontoethmoidal cells were noted in 72.4% of patients. Although the extent of ESS must be individualized, a high prevalence of features reflecting suboptimal surgery that could limit the success of ESS was identified. These findings merit further consideration for focused training during residency and continuous professional development activities. Full article

Background: A centrally limited radiological pattern, marked by mucosal thickening in the central sinonasal cavity with relatively unaffected surrounding sinuses, has been linked to allergy in chronic rhinosinusitis (CRS). However, a comparison between allergic and non-atopic CRS patients is lacking. The role of anatomical variations in the ostiomeatal complex also remains unclear. Methods: Adult CRS patients with allergic rhinitis, asthma, eczema, and positive allergy tests were recruited. CRS patients without atopic disease and negative allergy tests were controls. CT scans were evaluated for the centrally limited radiologic pattern. Anatomical variations in the ostiomeatal complex were also examined. Results: The study included 15 allergic CRS and 17 non-atopic CRS participants. Allergic CRS patients showed a higher prevalence of centrally limited sinus disease compared to non-atopic CRS patients (50% vs. 14.7%, p < 0.01). No anatomical variations were conclusively linked to allergy status or the centrally limited sinus disease. Conclusion: Centrally limited sinus disease on radiology is associated with underlying allergy in CRS but should not be the primary diagnostic tool. Anatomical variants did not clearly relate to allergy status or the radiologic pattern but this requires further studies. Full article

Background: Sinusitis, whether acute or chronic, is likely due at least in part to disruptions in the microbiota of the paranasal sinuses. Sinus cultures are often employed to guide medical treatment. Objective: To quantify the contemporary microbiology of the paranasal sinuses and better understand the utility of paranasal sinus cultures. Methods: We identified patients from 2018 to 2019 with sinus cultures taken by an otolaryngologist in the outpatient setting in our healthcare system with a concurrent diagnosis of acute or chronic rhinosinusitis. These cultures were analyzed based on their culture type and result. The most commonly isolated bacteria were further analyzed by species; Staphylococcus resistance patterns were analyzed as well. Results: A total of 2302 culture samples were collected: 2012 (87%) bacterial, 287 (13%) fungal, and 3 (0.1%) mycobacterial cultures. The results of more than half (1142, 57%) of these bacterial cultures were positive for a named genus, while those of 592 (29%) were positive for normal sinus flora and 16 (0.8%) for normal oral flora, and those of 183 (9%) showed no growth. The results of another 79 (4%) bacterial cultures were positive for unnamed bacteria, which were not further classified (e.g., Gram-negative rods). Of the positive bacterial cultures with named genera, the most common genera identified was Staphylococcus (383, 34%). Of these, the most common species of Staphylococcus was S. aureus (311, 81%), 42 of which (14%) showed methicillin resistance (MRSA). Of the fungal cultures, 265 (92%) resulted in no growth, and all three mycobacterial cultures showed no growth. Conclusions: In contrast to fungal cultures, the majority (57%) of sinus bacterial cultures showed positive results, with the identification of a named genus, highlighting the potential utility of this assay in guiding medical therapy.

Although the cough reflex is one of the essential protective mechanisms in the respiratory tract, it is considered a considerable health problem in adults and children when it becomes chronic and hypersensitive. However, the need for biomarkers for chronic cough in children and adults is critical. The problem with cough is also a severe symptom in hypersensitivity children. Respiratory infections are a considerable challenge for pediatricians, especially in allergic children. The term cough hypersensitivity syndrome, although introduced in adults, was questioned for children. Eosinophil cationic protein (ECP) is a promising marker for chronic cough but still needs to be validated and proved in clinical settings. In this review article, we aimed to discuss the possible role of ECP in connection to IgE for chronic cough in children. Full article

Cystic fibrosis (CF) is an autosomal recessive disorder that results in deranged ion transport and affects multiple organ systems, including the upper and lower respiratory tracts. People with CF (PwCF) often develop chronic rhinosinusitis (CRS) with or without nasal polyposis. CRS can significantly decrease quality of life for PwCF and can lead to more frequent pulmonary exacerbations. The management of CRS in PwCF is different from that in individuals without CF. Novel therapies have emerged in the last several years that have drastically altered the progression of both pulmonary and sinonasal disease in people with CF. It is critical for providers who manage CF-related CRS to understand the unique characteristics and challenges that coincide with this disease process. This review article aims to provide readers with an overview of the pathophysiology of CF and to summarize best practice strategies for the management of CF-related CRS. Full article

Central compartment atopic disease (CCAD) is a distinct phenotype within chronic rhinosinusitis with nasal polyps (CRSwNP) with a pathophysiology that bridges the gap between allergy and CRSwNP, an association that was previously ambiguous. Understanding this endotype and its link to allergic disease is crucial for improved CCAD management. Using a systematic search and an independent dual-reviewer evaluation and data extraction process, this scoping review examines the clinical features, management options, and treatment outcomes of CCAD. Central compartment (CC) polypoid changes of the MT predominantly correlate with allergic rhinitis, increased septal inflammation, oblique MT orientation, and decreased nasal cavity opacification and Lund–Mackay scores compared to other CRSwNP subtypes. CCAD patients also exhibit higher rates of asthma, allergen sensitization, and hyposmia or anosmia. Surgical outcomes, including revision rate and SNOT-22 improvement, are favorable in CCAD as well. In conclusion, CCAD primarily affects atopic individuals and is managed using endoscopic sinus surgery combined with treating the underlying allergy. Continued research is needed to further refine understanding and develop optimal treatment strategies of this emerging CRS subtype. Full article

The authors describe an unusual case of chemical sinusitis and orbital cellulitis secondary to a sodium hypochlorite accident in a patient who had just undergone root canal treatment. The patient presented with acute, progressive symptoms of unilateral maxillary sinusitis, facial cellulitis and orbital cellulitis which began hours after root canal treatment on the ipsilateral side. He was admitted to hospital under the care of the Otorhinolaryngology team and reviewed regularly by the Ophthalmologists. He underwent Endoscopic Sinus Surgery during his hospital stay. The intraoperative findings revealed necrotic sinus mucosa and slough within the involved maxillary sinus, which were suggestive of chemical burn injury induced by the highly alkaline sodium hypochlorite solution used during root canal treatment. He was treated postoperatively with regular nasal toilet, culture-directed antibiotics and topical ocular pressure-lowering eyedrops. He displayed a slow recovery with eventually no orbital sequelae, but experienced persistent cheek numbness three months post-injury. Severe chemical sinusitis with orbital cellulitis secondary to sodium hypochlorite accident is a rare complication of root canal treatment, with potentially severe consequences. It can present with symptoms similar to complicated acute bacterial sinusitis. Otorhinolaryngologists and dental surgeons should maintain a high index of suspicion when managing a patient post-root canal treatment with symptoms of unilateral sinusitis, facial cellulitis, orbital cellulitis and even airway compromise. This would allow prompt intervention before sight or life-threatening complications set in. Full article

Introduction: Chronic rhinosinusitis with nasal polyps (CRSwNP) and severe eosinophilic asthma (SEA) are common comorbidities characterised by type 2 inflammation associated with increased expression of interleukin 5. Methods: Eight patients with SEA and severe CRSwNP attended the Scottish Centre for Respiratory Research as part of a clinical trial (EudraCT number 2019-003763-22). Following an initial 4-week run-in period (baseline) when patients took their usual inhaled and intranasal corticosteroid treatment for SEA and CRSwNP, they all received subcutaneous benralizumab 30 mg q4w for 12 weeks. Results: Following 12 weeks of benralizumab, no significant differences were detected in nasal global symptom visual analogue score (VAS), hyposmia VAS, total nasal symptom score, or peak nasal inspiratory flow. In contrast, Asthma Control Questionnaire significantly improved along with near-complete depletion of peripheral blood eosinophils by 99%, while eosinophil-derived neurotoxin fell by 72%. Conclusions: Greater improvements in patient-reported outcomes related to asthma were observed than with CRSwNP in response to benralizumab. Full article

(1) Background: A number of studies have demonstrated the connection between developing or exacerbating chronic respiratory diseases in adults and children. However, still, few studies focus on reducing exacerbations via immunomodulation. (2) Methods: In this pilot study, a total of 25 pediatric and adult patients with bronchial asthma (BA) and chronic obstructive pulmonary disease (COPD)/persistent bacterial bronchitis (PBB) were included, administered over-the-counter (OTC) immunomodulators and followed up for 6 or 12 months. (3) Results: We observed a decrease in the frequency of exacerbations with slight improvements in functional respiratory indicators in adults on their second and third visits and a reduced number of exacerbations and improved spirometry indices in children with BA, although exacerbations requiring hospital admission remained at a similar rate. (4) Conclusions: We confirmed that the number of exacerbations of underlying chronic respiratory disease in adults and children could be reduced after the administration of OTC immunomodulators, probably by optimizing the immune resistance to common viral infections.

Tranexamic acid (TXA) is an inexpensive and widely used medication indicated for the reduction of bleeding. There are data showing the efficacy of intravenous (IV) and topical TXA in endoscopic sinus surgery (ESS) but the safety of this practice is not well studied. The objective of this study was to assess the safety of using both IV and topical TXA in ESS. A scoping review was performed to investigate the effect of TXA on respiratory epithelia. A retrospective single-surgeon study was used to assess 177 comprehensive ESS cases from January 2017–December 2019 for the safety of combined IV and topical TXA. The scoping review demonstrated that respiratory epithelia could withstand a wide range of TXA concentrations without detrimental morphological effects. Topical TXA may have positive effects on wound healing and inflammation. The retrospective study showed no thromboembolic complications attributable to TXA in the 28 days after ESS. Only two patients (1.3%) who received TXA re-presented with post-operative bleeding. The use of IV and topical TXA is safe with regards to its effect on respiratory epithelium and thromboembolic disease. Topical TXA may have more positive effects than merely the reduction of bleeding following ESS. Full article

Despite significant advances in pharmacological treatment over the last few decades, COPD remains a heavy burden on the health systems around the world, affecting approximately 210 million people, with elevated morbimortality and socioeconomic impact. Barriers to healthcare access were even more evident during the coronavirus disease 19 (COVID-19) pandemic and increased patients’ vulnerability to physical deconditioning, depression, and social isolation. Home-based respiratory care in patients with COPD provides a valuable contribution to effective disease management, with potential advantages for monitoring, treatment adherence, and cost reduction. Technological innovation allows clinical markers of interest, such as respiratory frequency, pulmonary function, and oxygen saturation, to be tracked remotely from the patients’ homes, providing a better understanding of their real needs. Home-based telerehabilitation can also be a viable alternative to hospital-based programs. Here, we highlight the full extent of health benefits of HRC in COPD, particularly for patients with a higher risk of exacerbations, multiple comorbidities, and limited access to health services.

Introduction: Acute Otitis Media (AOM) is the most commonly-occurring bacterial complication in childhood. After making certain corrections to the patients’ dietary habits, which we found to be excessively high in animal-based and industrially-processed foods, we observed a significant reduction in recurrent colds and their bacterial complications. We promote an original way of treating these diseases, since until now the conventional treatment is based on pharmacological and surgical treatment. From our point of view, the mucosa that covers the entire ENT area is in a pro-inflammatory and hyper-reactive state, as a consequence of the alterations produced by an inadequate diet. For us there is no difference in the nutritional treatment of the different mucous membranes that cover the ENT area. The purpose of the study was to assess the effects of the Traditional Mediterranean Diet (TMD) on patients diagnosed with Recurring Acute Otitis Media (RAOM). Methods: prospective pre-postest comparison study with 48 girls and 42 boys aged 1–5 years, each of whom had been and included on the 1-year programme “Learning to eat the Mediterranean Way”, designed to encourage the adoption of the TMD. We studied clinical and therapeutic variables and various anthropometric parameters. Results: all the symptomatic indicators studied (number and intensity of episodes of otitis and emergency admissions) showed a positive and statistically significant evolution in RAOM. By the end of the study, none of the patients met the criteria for classification as RAOM, and 60% percent of patients did not present any further episodes of AOM. In line with the above, the use of anti-microbial drugs and symptomatic treatments reduced considerably; the use of antibiotics dropped from 4.30 occasions/patient/year, to 0.66 (p < 0.001), and the used of symptomatic treatments dropped from 7.63 to 2.75 (p < 0.001). The level of family satisfaction was very high. Conclusions: the adoption of the Traditional Mediterranean Diet has been demonstrated to significantly reduce occurrence of acute otitis media and may contribute to the treatment of patients diagnosed with recurrent acute otitis media.

Chronic obstructive pulmonary disease (COPD) is a global public health burden that stands out as a leading cause of mortality around the world, especially in less developed countries. COPD treatment should be centered on the individual necessities of each patient, integrating pharmacological therapy, immunization, nutritional support, pulmonary rehabilitation and control of comorbidities. Combining a long-acting antimuscarinic (LAMA) with a long-acting beta2-agonist (LABA) bronchodilator has proven to be more effective than monotherapy with LABA or LAMA, in terms of the functional improvement of forced expiratory volume (FEV1), symptoms and life quality and may be helpful in patients with progressive dyspnea. The eosinophil blood count is a simple biomarker that could guide personalized treatment strategies by identifying patients with greater clinical benefits of inhaled corticosteroid (ICS) treatment. However, one critical concern is the increased risk of pneumonia in individuals treated with ICS. Full article

It is established that non-white people experience worse health outcomes than white people within the same population. Equity addresses differences between patient subgroups, allowing needs-based distribution of resources. The use of quality-of-life (QoL) tools to assist clinical decision making such as the SNOT-22 for chronic rhinosinusitis promotes equality, not equity, as quality-of-life (QoL) tools provide the same criteria of symptom scoring across diverse populations. We considered the effects of ethnicity and race on SNOT-22 scores and whether these scores should be adjusted to improve equity. PubMed and MEDLINE provided papers for a scoping review. A combination of the following search terms was used: patient-reported outcome measures (PROM) (OR) quality of life; (AND) race (OR) ethnicity (OR) disparities; (AND) otolaryngology (OR) SNOT-22 (OR) sinusitis. The first study identified no evidence of ethnic variability in SNOT-22 scores. However, the study did not represent the local population, including 86% white people. Other studies identified baseline SNOT-22 disparities with respect to population demographics, gender, and age. Ethnic differences appear to exist in acute sinusitis symptomatology. In other fields both within and outside of otorhinolaryngology, ethnic differences exist with regard to QoL tools. This scoping review identified a paucity of data in rhinology. However, evidence implies some form of correction to QoL scores could help promote equity for non-white patients. Full article
