Airways Type-2 Related Disorders: Multiorgan, Systemic or Syndemic Disease? Int J Mol Sci 2024; 25:730.

Abstract
Chronic rhinosinusitis (CRS) has recently undergone a significant paradigm shift, moving from a phenotypical classification towards an "endotype-based" definition that places more emphasis on clinical and therapeutic aspects. Similar to other airway diseases, like asthma, most cases of CRS in developed countries exhibit a dysregulated type-2 immune response and related cytokines. Consequently, the traditional distinction between upper and lower airways has been replaced by a "united airway" perspective. Additionally, type-2 related disorders extend beyond respiratory boundaries, encompassing conditions beyond the airways, such as atopic dermatitis. This necessitates a multidisciplinary approach. Moreover, consideration of possible systemic implications is crucial, particularly in relation to sleep-related breathing diseases like Obstructive Sleep Apnoea Syndrome (OSAS) and the alteration of systemic inflammatory mediators such as nitric oxide. The trends in epidemiological, economic, and social burden are progressively increasing worldwide, indicating syndemic characteristics. In light of these insights, this narrative review aims to present the latest evidence on respiratory type-2 related disorders, with a specific focus on CRS while promoting a comprehensive perspective on the "united airways". It also introduces a novel concept: viewing these conditions as a multiorgan, systemic, and syndemic disease.

Abstract
BACKGROUND Dupilumab, a monoclonal anti-IL-4Rα antibody, is approved for several type 2 mediated inflammatory diseases like asthma, atopic dermatitis, and diffuse type 2 chronic rhinosinusitis (CRS). Clinical studies had reported a transient increase in blood eosinophils during dupilumab therapy. This study aimed to assess the impact of elevated blood eosinophils on clinical outcome and to investigate the cause of high blood eosinophil levels under dupilumab therapy. METHODS Patients suffering from diffuse type 2 CRS treated with dupilumab were examined on days 0, 28, 90, and 180 after therapy start. Sino-Nasal-Outcome-Test Score (SNOT-22), Total Nasal Polyp Score (TNPS), and blood samples were collected. Cytokine measurements and proteomics analysis were conducted. Flow cytometry analysis measured receptor expression on eosinophils. RESULTS Sixty-eighty patients were included. Baseline eosinophilia ≥0.3G/L was observed in 63.2% of patients, and in 30.9% of patients, eosinophils increased by ≥0.5G/L under dupilumab. Subjects with eosinophilia ≥0.3G/L at baseline had the best SNOT-22 mean change compared to no eosinophilia. Eosinophil elevation during dupilumab therapy had no impact on clinical scores. The eosinophil adhesion molecule VCAM-1 decreased significantly during therapy in all patients. The chemokine receptor CXCR4 was significantly down- and IL-4 upregulated in subjects with eosinophil increase. CONCLUSION Our findings suggest that increased eosinophils in type 2 CRS are associated with a good clinical response to dupilumab. Patients with elevated IL-4 at baseline developed dupilumab-induced transient eosinophilia. We identified the downregulation of VCAM-1 and surface markers CD49d and CXCR4 on eosinophils as possible explanations of dupilumab-induced eosinophilia.

Abstract
OBJECTIVE To critically review the literature on nasal nitric oxide (nNO) and its current clinical and research applicability in the diagnosis and treatment of different sinonasal inflammatory diseases, including acute bacterial rhinosinusitis (ABRS), allergic rhinitis (AR), and chronic rhinosinusitis (CRS). METHODS A search of the PubMed database was conducted to include articles on nNO and sinonasal diseases from January 2003 to January 2020. All article titles and abstracts were reviewed to assess their relevance to nNO and ABRS, AR, or CRS. After selection of the manuscripts, full-text reviews were performed to synthesize current understandings of nNO and its applications to the various sinonasal inflammatory diseases. RESULTS A total of 79 relevant studies from an initial 559 articles were identified using our focused search and review criteria. nNO has been consistently shown to be decreased in ABRS and CRS, especially in cases with nasal polyps. While AR is associated with elevations in nNO, nNO levels have also been found to be lower in AR cases with higher symptom severity. The obstruction of the paranasal sinuses is speculated to be an important variable in the relationship between nNO and the sinonasal diseases. Treatment of these diseases appears to affect nNO through the reduction of inflammatory disease burden and also mitigation of sinus obstruction. CONCLUSION nNO has been of increasing interest to researchers and clinicians over the last decade. The most compelling data for nNO as a clinical tool involve CRS. nNO can be used as a marker of ostiomeatal complex patency. Variations in measurement techniques and technology continue to impede standardized interpretation and implementation of nNO as a biomarker for sinonasal inflammatory diseases.

Abstract
An important role has been recently reported for bacterial biofilm in the pathophysiology of chronic diseases, such as chronic rhinosinusitis (CRS). CRS, affecting sinonasal mucosa, is a persistent inflammatory condition with a high prevalence around the world. Although the exact pathological mechanism of this disease has not been elicited yet, biofilm formation is known to lead to a more significant symptom burden and major objective clinical indicators. The high prevalence of multidrug-resistant bacteria has severely restricted the application of antibiotics in recent years. Furthermore, systemic antibiotic therapy, on top of its insufficient concentration to eradicate bacteria in the sinonasal biofilm, often causes toxicity, antibiotic resistance, and an effect on the natural microbiota, in patients. Thus, coming up with alternative therapeutic options instead of systemic antibiotic therapy is emphasized in the treatment of bacterial biofilm in CRS patients. The use of topical antibiotic therapy and antibiotic eluting sinus stents that induce higher antibiotic concentration, and decrease side effects could be helpful. Besides, recent research recognized that various natural products, nitric oxide, and bacteriophage therapy, in addition to the hindered biofilm formation, could degrade the established bacterial biofilm. However, despite these improvements, new antibacterial agents and CRS biofilm interactions are complicated and need extensive research. Finally, most studies were performed in vitro, and more preclinical animal models and human studies are required to confirm the collected data. The present review is specifically discussing potential therapeutic strategies for the treatment of bacterial biofilm in CRS patients.

Abstract
Nasal nitric oxide concentrations are extremely low in primary ciliary dyskinesia (PCD), and measurement of this nasal gas is recommended as a PCD diagnostic test in cooperative patients aged 5 years and older. However, nasal nitric oxide measurements must be performed with chemiluminescence analyzers using a standardized protocol to ensure proper results, because nasal nitric oxide values can be influenced by various internal and external factors. Repeat nasal nitric oxide testing on separate visits is required to ensure that low diagnostic values are persistent and consistent with PCD. This technical paper presents the standard operating procedures for nasal nitric oxide measurement used by the PCD Foundation Clinical and Research Centers Network at various specialty centers across North America. Adherence to this document ensures reliable nasal nitric oxide testing and high diagnostic accuracy when employed in a population with appropriate clinical phenotypes for PCD.

Abstract
OBJECTIVES We conducted a systematic literature review (SLR) of randomized controlled trials and real-world evidence (RWE) studies to determine the humanistic (e.g. health-related/disease-specific quality of life [QOL]) and economic (e.g. direct and indirect costs) burdens of chronic rhinosinusitis with nasal polyposis (CRSwNP). METHODS The SLR adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Embase, MEDLINE and Evidence-Based Medicine Reviews databases were searched using OVID. Relevant studies involving adult patients with CRSwNP published between 1 January 2008 and 16 February 2019 were included, with relevant conference abstracts from 1 January 2017, onward. RESULTS Sino-Nasal Outcomes Test (SNOT)-22 was the most frequently used disease-specific health-related QOL/patient-reported outcomes instrument for patients with CRSwNP. Baseline SNOT-22 scores ranged from 25 to 73 for surgical candidates and from 14 to 56 for medically managed patients with CRSwNP. Mean baseline EuroQol-5 Dimensions (EQ-5D) index for patients with CRSwNP ranged from 0.81 to 0.86, and mean baseline Short Form-6 Dimensions (SF-6D) ranged from 0.67 to 0.75. Three months (EQ-5D) and 5 years (SF-6D) post-endoscopic sinus surgery (ESS), rates increased from 0.81 to 0.89 and from 0.69 to 0.80, respectively. One year post-diagnosis, patients with CRSwNP had significantly more systemic prescriptions, underwent significantly more medical procedures, demonstrated greater health care resource utilization and had significantly greater mean health care costs compared with matched controls (all p < .001). Overall, for patients with initial ESS, CRSwNP was associated with higher disease-related expenditures compared with CRS without nasal polyposis (NP), even for patients who did not undergo revision surgery. CONCLUSIONS This SLR identified substantial humanistic burden among surgery candidates. RWE shows that surgeries were used to treat relatively more severe CRSwNP patients as recommended by guidelines. Patient QOL is improved significantly after surgery; however, there is a lack of evidence on patients with revision surgery. Surgery is also associated with higher costs, and the presence of NP was a predictor of revision surgery. Patients with CRSwNP demonstrate greater health care resource utilization and costs compared to those with CRS without NP. Costs associated with different severity of CRSwNP and revision surgery need to be assessed further.

Abstract
BACKGROUND The objective of this work was to assess the efficacy of serum eosinophil cationic protein (ECP) concentration in predicting early postoperative recurrence in patients with chronic rhinosinusitis with nasal polyps (CRSwNP). METHODS We prospectively enrolled CRSwNP patients to receive bilateral functional endoscopic sinus surgery (FESS) and followed them for 1 year. Serum ECP level was measured within 1 week before surgery. Demographics and associated medical factors were analyzed with the surgical outcome, and nasal polyp histology was microscopically examined. RESULTS Overall, 58 patients met the inclusion criteria and underwent FESS. After at least a 1-year follow-up period, 9 patients had postoperative recurrence, with significantly higher serum ECP levels (p = 0.030). Receiver operating characteristic curve analysis showed the optimal cutoff level of serum ECP concentration for predicting the postoperative recurrence of nasal polyps was 21.8 µg/L (p = 0.030). Regardless of atopy status and histology type, logistic regression analysis showed that a higher ECP level was the sole significant factor related to early postoperative recurrence of nasal polyps (odds ratio, 54.8; p = 0.014). Cox proportional hazard regression analysis revealed that the hazard ratio of CRSwNP patients with an ECP level of >21.8 µg/L resulting in early postoperative recurrence was 7.6 (p = 0.011). CONCLUSION Serum ECP appears to be a feasible predictor for early postoperative recurrence of nasal polyps. CRSwNP patients with preoperative serum ECP levels of ≥21.8 µg/L had an approximately 55-fold increased risk of early recurrence. CRSwNP patients with higher preoperative serum ECP levels should be closely monitored within the first year after surgery.

Abstract
BACKGROUND A hallmark of eosinophilic chronic rhinosinusitis with nasal polyps (eCRSwNP) is mucosal eosinophil-predominant inflammation. Nasal nitric oxide (nNO) is a known biomarker of eosinophilic inflammation in the upper airway. However, the utility of nNO measurement in the upper airway remains controversial. The present study aimed to compare the use of other clinical parameters with nNO to prediagnose patients with eCRSwNP from Central China. METHODS From June 2019 to December 2019, 70 patients with CRSwNP undergoing endoscopic sinus surgery and 30 healthy subjects were enrolled. nNO measurements were performed in all of these subjects. Computed tomography scans, full blood count with differential analysis, and determination of total immunoglobulin E (total IgE) and plasma cytokines were performed before surgery. Receiver operating characteristic curves and logistic regression analysis were used to assess the predictive potential of the clinical parameters. RESULTS We recruited 24 patients with eCRSwNP and 46 with noneosinophilic CRSwNP (non-eCRSwNP). In patients with eCRSwNP, nNO levels were significantly higher than those in patients with non-eCRSwNP (p < 0.0001). Blood eosinophil percentages and counts, total IgE, and CT-derived ethmoid sinus and maxillary sinus ratio (E/M ratio) were all significantly higher compared with those in patients with non-eCRSwNP (p < 0.05). To diagnose eCRSwNP, the highest area under the curve (0.803) was determined for nNO. At a cutoff of >329 parts per billion (ppb), the sensitivity was 83.30% and the specificity was 71.70%. However, the levels of plasma cytokines Th1/Th2 were not significantly different between the histological types of CRSwNP (p > 0.05). CONCLUSION Measurement of nNO is useful for the early diagnosis of eCRSwNP.

Nasal Nitric Oxide in Chronic Rhinosinusitis with or without Nasal Polyps: A Systematic Review with Meta-Analysis. J Clin Med 2020; 9:jcm9010200.

Abstract
Background and Aims: There has been a recent growing interest in the role of nasal nitric oxide (nNO) as a biomarker for osteomeatal complex obstruction in paranasal sinus diseases. By using meta-analysis, we systematically reviewed the literature to establish the possible link between nNO concentration and chronic rhinosinusitis with nasal polyps (CRSwNP) or without (CRSsNP). Methods: We systematically searched the EMBASE, PubMed, Scopus, and Web of Science databases for related studies. Differences between controls and cases were reported as standardized mean difference (SMD), with 95% confidence intervals (95% CI), using the random-effects method. Results: We selected 23 articles for the final analysis: 15 with data on 461 CRSwNP patients and 384 healthy controls, 10 with data on 183 CRSsNP patients and 260 controls, and 14 studies on 372 CRSwNP and 297 CRSsNP patients. CRSwNP patients showed significantly lower nNO values when compared to both healthy controls (SMD: −1.495; 95% CI: −2.135, −0.854; p < 0.0001) and CRSsNP patients (SMD: −1.448; 95% CI: −2.046, −0.850; p < 0.0001). Sensitivity and subgroup analyses confirmed the results, which were further refined by regression models. They showed that an increasing aspiration flow is related to a greater difference in nNO levels between cases and control subjects. We also documented lower nNO levels in CRSsNP patients with respect to controls (SMD: −0.696; 95% CI: −1.189, −0.202; p = 0.006), being this result no longer significant when excluding patients in therapy with intranasal corticosteroids. As shown by regression models, the increased Lund–Mackay score indicates a high effect size. Conclusions: nNO levels are significantly lower in CRSwNP, especially when using higher aspiration flows. Additional studies are needed to define one single standardized method and normal reference values for nNO.

Abstract
BACKGROUND Although cases of empty nose syndrome (ENS) are not very common, the suffering that ENS causes patient is immense and could be very difficult to imagine. Nasal nitric oxide (nNO) is an airway disease biomarker, and its levels increase after endoscopic sinus surgery. The trend of nNO levels in ENS before and after surgical treatment remains unknown. This study aimed to evaluate the role of nNO in ENS. METHODS Patients with ENS who received surgical implantation and with chronic hypertrophic rhinitis (CHR) who underwent turbinoplasty and completed at least 1 year of follow-up were prospectively enrolled. nNO measurements and subjective assessments [SinoNasal Outcome Test (SNOT)-22, Beck Depression Inventory (BDI)-II, and Beck Anxiety Inventory (BAI)] were performed preoperatively and at 3, 6, and 12 months postoperatively. RESULTS We enrolled 19 ENS and 12 CHR patients. nNO levels were significantly lower in the ENS than in the CHR patients before surgical treatment (p < 0.001). nNO levels in the ENS patients significantly increased 3 months after implantation and remained plateaued (p = 0.015). BDI-II and BAI scores significantly improved after surgical treatment for the ENS patients but not for the CHR patients; changes in nNO levels correlated well with improvements in BDI-II and BAI scores (p = 0.025 and 0.035, respectively). CONCLUSIONS nNO significantly increased at third month after surgical treatment and remained plateaued in ENS patients. This increase correlated with improvements in BDI-II and BAI scores. Therefore, nNO may be important in assessing the psychiatric status of empty nose syndrome.

Abstract
Background Nasal nitric oxide (nNO) could be a biomarker for nasal passage inflammation and sinus ostial patency. We have aimed to investigate the nNO concentration and the effect of antibiotic therapy in children with perennial allergic rhinitis (PAR) children with/without acute bacterial sinusitis. Methods We enrolled a cohort of 90 and 31 children with PAR, without and with acute unilateral maxillary sinusitis, and 79 normal children. Acute bacterial maxillary sinusitis was diagnosed based on clinical signs and symptoms, radiographic examination and nasal fibroendoscopy. Rhinitis control assessment test (RCAT), rhinomanometry, nNO and fractional exhaled NO (FENO) measurements were performed before and 2 weeks after antibiotic therapy. Results We found significantly higher mean nNO levels, FENO values, and total nasal resistance in children with PAR than in normal children (p < 0.05). Acute unilateral maxillary sinusitis was associated with lower lesion-side nNO levels, higher FENO values, total nasal resistance, and poor RCAT scores (p < 0.05). In multivariate analysis, age, IgE, and acute maxillary sinusitis were significant factors influencing nNO levels in children with PAR. The lesion-side nNO levels, FENO values, total nasal resistance, and RCAT scores were reversed after antibiotic therapy (p < 0.05). The lesion-side nNO levels were significantly correlated to nasal obstructive scores (r = 0.59, p < 0.05) and expiratory nasal resistance (r = -0.54, p < 0.05) in the acute maxillary sinusitis. A cut-off nNO value of 538 ppb showed 100% sensitivity and 94.9% specificity, to predict PAR from normal children. An nNO value of 462 ppb showed 100% sensitivity and 100% specificity to discriminate between the lesion-side and the unaffected sinus-side in PAR children with acute unilateral maxillary sinusitis. Conclusions We conclude that the obstruction of NO from the sinus into the nasal passage is the likely explanation for the decreased lesion-side nNO levels in acute unilateral maxillary sinusitis. nNO is a non-invasive biomarker with high sensitivity to diagnose and monitor treatment responses of PAR patients with acute rhinosinusitis. Both nNO and FENO levels return to baseline following antibiotic therapy, supporting the "one airway one disease" concept.

Abstract
INTRODUCTION Allergic rhinitis (AR) is a disorder with high prevalence worldwide. Identification of clinically relevant allergens is the key step for the diagnosis, allergen avoidance and allergen specific immunotherapy for AR. Areas covered: With the new findings of mechanisms of AR and the development of technology, much progress has been achieved in the diagnosis of AR recently. We review the recent advances about local IgE, in vivo and in vitro tests, cytological diagnosis and nitric oxide (NO) in the diagnosis of AR. Expert commentary: AR is traditionally diagnosed with the combined evaluation of history and allergen sensitization by in vivo skin prick tests and in vitro allergen specific IgE in serum, to confirm the correlation between clinical history and potential allergens. Nasal provocation test and local IgE measurement can be used to diagnose local AR. Allergen microarray has the ability to detect more potential allergens. Basophil activation and mast cell activation tests can be used in allergen diagnosis and to modify the response to immunotherapy, while cytological diagnosis is useful in the differential diagnosis of AR and non-AR. Nasal NO has been confirmed to be an optimal biomarker to discriminate between AR and non-AR.

Abstract
BACKGROUND Bacteria, particularly in the biofilm state, may be implicated in the pathogenesis of chronic rhinosinusitis (CRS) and enhance antibiotic resistance. Nitric oxide (NO) is a gaseous immunomodulator with antimicrobial activity and a short half-life, complicating achievement of therapeutic concentrations. We hypothesized that a novel microparticle-based delivery platform, which allows for adjustable release of NO, could exhibit potent antibacterial effects. METHODS Porous organosilica microparticles (SNO-MP) containing nitrosylated thiol groups were formulated. Dissociation of the nitrosothiol groups generates NO at body temperature. The susceptibility of bacterial isolates from CRS patients to SNO-MP was evaluated through a colony forming unit (CFU) assay. Serial dilutions of SNO-MP in triplicate were incubated with isolates in suspension for 6 hours followed by plating on tryptic soy agar and overnight incubation followed by CFU quantification. Statistical analysis was performed with SPSS using one-way analysis of variance with Bonferroni correction. RESULTS SNO-MP displayed antibacterial activity against gram-positive (methicillin-resistant and -sensitive Staphylococcus aureus) and gram-negative (Pseudomonas aeruginosa, Enterobacter aerogenes, and Proteus mirabilis) isolates. SNO-MP induced dose-dependent reductions in CFU across all strains. Compared with controls and blank nanoparticles, SNO-MP (10 mg/mL) induced a 99.99%-100% reduction in CFU across all isolates, equivalent to a 5-9 log kill (p < 0.005). There was no statistically significant difference in CFU concentration between controls and blank microparticles. CONCLUSION SNO-MP demonstrates potent bactericidal effect against antibiotic-resistant CRS bacterial strains.

Abstract
Background Chronic rhinosinusitis (CRS) with nasal polyps (CRSwNP) and CRS without nasal polyps (CRSsNP) nasal polyps is a global health concern. Several clinical biomarkers, such as inhaled carbon monoxide and exhaled nitric oxide (NO), have been studied to assess the presence and degree of inflammation in the airway mucosa. Objective To evaluate the clinical application of exhaled nasal NO (nNO) in distinguishing between CRSwNP and CRSsNP in consideration of the atopic status of patients. Methods Eighty-eight patients with CRS and 20 healthy volunteers were recruited for this study. The exhaled nNO level was measured by using a hand-held device. Nasal endoscopy (with Lund-Mackay scoring of CRS) and sinus computed tomographies (CT) were used to evaluate the nasal cavity and sinuses of the subjects. Atopic status was confirmed by using skin prick tests (SPTs). Results The mean ∓ standard deviation (SD) levels of nNO in patients with CRSsNP were significantly higher than those in patients with CRSwNP (591 ∓ 153 ppb versus 360 ∓ 181 ppb, p <0.001), whereas patients with CRS exhibited lower levels of nNO compared with the control subjects (449 ∓ 204 ppb versus 881 ∓ 161 ppb, p <0.001). Patients with atopy and with and without nasal polyps exhibited significantly higher levels of nNO compared with patients without atopy (atopic CRSsNP versus nonatopic CRSsNP, 734 ∓ 220 ppb versus 503 ∓ 92 ppb [p <0.001]; atopic CRSwNP versus nonatopic CRSwNP, 518 ∓ 161 ppb versus 299 ∓ 150 ppb [p <0.001]). The levels of nNO were negatively correlated with the Lund-Mackay scores in both atopic (r = -0.45; p = 0.016) and nonatopic (r = -0.600; p <0.001) patients with CRS. Receiver operating characteristic curves differentiated patients as CRSwNP, CRSsNP, and healthy controls, and in atopic and nonatopic subgroups, with acceptable sensitivity and specificity (>70 to 90%). Conclusion Exhaled nNO levels can be used to distinguish between patients with CRSwNP and patients with CRSsNP. However, the atopic status of the patient influenced the use of nNO as a diagnostic or monitoring biomarker in CRS.

Abstract
Unilateral sinus disease (USD) can sometimes be difficult to accurately diagnose before surgery. The application of nasal nitric oxide (nNO) for USD diagnosis and its surgical outcome in USD has not been reported in the literature. We prospectively enrolled sixty-six USD patients who underwent endoscopic sinus surgery for fungal rhinosinusitis (n = 19), chronic rhinosinusitis (CRS) without nasal polyps (n = 13), CRS with nasal polyps (n = 12) and sinonasal mass lesions (n = 22). nNO levels were measured preoperatively and at three and six months postoperatively. Correlations between nNO levels and potential clinical parameters, type of disease, disease severity, and disease-related quality of life (QOL) were assessed. Unlike bilateral CRS, in USD, nNO levels did not correlate with disease severity or postoperative QOL improvements. Except for fungus group, there were no differences in nNO levels between lesion and non-lesion sides in all the other groups. nNO levels on both sides were significantly elevated six months postoperatively in all groups. Fungal rhinosinusitis patients had the lowest preoperative nNO levels, and a cutoff of 239.3 ppb had the best sensitivity (79.0%) and specificity (87.2%) for preoperative diagnosis. While preoperative nNO levels cannot serve as an alternative marker for disease severity of USD, they were lower in fungal rhinosinusitis patients than in other USD patients and may be useful for more accurate diagnosis prior to surgery.

Abstract
BACKGROUND Surgery improves symptoms for the majority of chronic rhinosinusitis (CRS) patients; however, physiological changes in the sinus cavities remain poorly characterized. Direct measurement of changes in airflow, pressure, temperature, humidity, and intranasal spray distribution following surgery is technically challenging. Accordingly, we have used computational fluid dynamic modeling to quantify how these parameters change postoperatively. METHODS Computed tomography images from a normal control, a patient with CRS preoperatively and postoperatively, and a patient following an endoscopic Lothrop procedure (ELP) were used to create 4 three-dimensional models of the sinus cavities. Changes in physiologic parameters and topical drug distribution were modeled (inhaled air at 16°C and 10% humidity) at the maxillary ostium, frontal recess, and sphenoid ostium. RESULTS Large differences were seen between models. Following surgery, the maxillary ostia were found on average to be cooler (by 2.4°C), with an increased airflow (0.26 m/second; from 0 m/second), and a 9% reduction in absolute humidity. Sphenoid ostial parameters followed a similar trend. Significant changes in frontal recess physiology were seen following ELP in which the recess was 4.2°C cooler, had increased airflow (0.76 m/second) and a 17% reduction in absolute humidity. Topical drug distribution increased with surgery, particularly after ELP. CONCLUSION Surgery changes the geometry and physiology of the paranasal sinuses. These changes are likely to have an impact on wound healing, mucociliary function, and microbial ecology in postoperative cavities. Application of this model to further understand the effects of surgery may help to optimize surgical techniques and improve topical drug delivery.
