Abstract
Introduction Jet aircraft pilots are exposed to huge pressure variation during flight, which affect physiological functions as systems, such as the respiratory system. Objectives The objective of the present investigation was to evaluate inflammatory changes of paranasal sinuses of jet aircraft pilots before and after a jet aircraft training program, using multislice computed tomography (CT), in comparison with a group of nonairborne individuals with the same age, sex, and physical health conditions. A second objective of the present study was to assess the association between the ostiomeatal complex obstruction and its anatomical variations. Methods The study group consisted of 15 jet aircraft pilots participating in the training program. The control group consisted of 41 nonairborne young adults. The 15 fighter pilots were evaluated before initiating the training program and after their final approval for the presence of inflammatory paranasal sinus disease. The ostiomeatal complex anatomical variations and obstructions were analyzed in pilots after the training program. Results Jet aircraft pilots presented higher incidence of mucosal thickening in maxillary sinus and anterior ethmoid cells than controls. Prominent ethmoidal bulla showed significant association with obstruction of the osteomeatal complex. Conclusions Jet aircraft pilots present increased inflammatory disease when compared with nonairborne individuals. The presence of a prominent ethmoidal bulla is associated with ostiomeatal complex obstruction.

Abstract
OBJECTIVES Chronic rhinosinusitis (CRS) is prevalent in people with cystic fibrosis (PwCF) and is often refractory to treatments. Uncontrolled CRS might negatively impact the lower airways and the quality of life. The aim of this study is to evaluate the burden of cystic fibrosis (CF)-related CRS in the era of CF transmembrane conductance regulator (CFTR) modulators. METHODS Adult PwCF were asked to fill in a questionnaire on sinonasal complaints, they underwent a nasal endoscopy, bacteriological sampling, and a CT scan. Afterwards, these outcome measures were compared between patients treated with and without modulators. RESULTS In the 122 included patients, CRS was present in 83%. CFTR modulators were prescribed in 48% of the patients, with a median of 10 months since the start of the treatment. Subjectively, the median SNOT-22 score was 16/110. Objectively, a median Lund-Kennedy score of 6/12 and modified Lund-Mackay score of 10/24 were observed. No correlation could be found between SNOT-22 score and other outcome measures including endoscopy and radiology. Altogether, 21% of the patients had controlled disease. When comparing patients treated with and without modulators, significantly lower CT scores (p = 0.0018) and less bacterial colonization (p = 0.0082) were observed in patients receiving modulators. CONCLUSION CF-CRS is highly prevalent in our cohort and only the minority of PwCF has a well-controlled disease. A multidisciplinary ENT-pneumology clinic would be beneficial, as there is a high discrepancy between patient-reported symptoms and the extent of the disease. CFTR modulators are promising, as lower CT scores and less bacterial colonization were observed in the modulator group. LEVEL OF EVIDENCE Level 3 Laryngoscope, 133:2898-2909, 2023.

Abstract
OBJECTIVE Understanding of how specific mutations impact the cystic fibrosis transmembrane conductance regulator (CFTR) protein has given rise to the classification of CF patients into low-risk and high-risk genotypes. Few prior studies have investigated differences in sinonasal disease between low-risk and high-risk CF genotypes. This multi-institutional review aimed to evaluate radiographic sinus disease severity based on genotype. METHODS A review was conducted on adult patients with CF evaluated between 2005 to 2017 at three academic institutions. Data including age, gender, CFTR mutation, and presence of a maxillofacial/sinus computed tomography scan was collected. A modified Lund-Mackay score (MLMS) was assigned to each scan, and the presence of sinus aplasia or hypoplasia was determined. Patients were further grouped depending on genotype into low- or high-risk for comparison. RESULTS A total of 126 patients were included with 99 patients in the high-risk and 21 in the low-risk groups. The high-risk group had significantly higher MLMS than the low-risk group (mean 13.88 vs. 8.06, P < 0.0001, 95% CI -8.196 to -3.462) The rate of frontal (P < 0.01), maxillary (P = 0.04), and sphenoid (P < 0.001) hypoplasia/aplasia was significantly higher in high-risk patients compared to low-risk. CONCLUSION This is one of the largest studies to date evaluating the impact of CF genotype on paranasal sinus development and disease. Genotype appears to impact sinonasal disease severity and also potentially paranasal sinus cavity development to a degree, although the exact mechanism is unknown.

Abstract
OBJECTIVE To evaluate the impact of FESS in children with chronic rhinosinusitis with nasal polyps, regarding their overall postoperative quality-of-life (QoL) and constituent QoL domains. Potential differences between cystic fibrosis (CF) sufferers and non-sufferers, or cases with recurrent sinonasal polyposis versus single-operations were also explored. METHODS 39 children were studied. The mean patient age was 10.9 years; four children suffered from cystic fibrosis. The children (or parents) completed the Glasgow Benefit Inventory for Children (GCBI) at least six months after their operation. The Mann-Whitney test compared the GCBI scores between non- and CF sufferers, as well as children with and without recurrent polyposis. RESULTS The median overall QoL score was 98. There were no statistically significant differences between CF sufferers and non-sufferers regarding their overall QoL, or the respective individual QoL domains, apart from their physical postoperative activity (p = 0.04). Twelve children demonstrated recurrent polyposis (30.7%); among them three were cystic fibrosis sufferers. No statistically significant differences were identified in the overall QoL score, or individual GCBI subscale scores between children with recurrent polyposis versus single-operations. Children with recurrent polyposis but not CF performed better regarding their overall QoL (p = 0.021) and medical status (p = 0.015), compared to their CF counterparts. CONCLUSION FESS performed for chronic rhinosinusitis with nasal polyps in children is associated with improved postoperative QoL, irrespective of the presence of CF (although the latter needs to be confirmed in larger patient cohorts). The absence of appreciable differences in the overall QoL, or its constituent domains, between single and re-operated children, indicate that the positive effect of FESS outweighed the burden of re-operation. Appropriate preoperative informed consent in cases of recurrent sinonasal polyposis necessitates acknowledging worse respective outcomes in CF sufferers.

Sino nasal inhalation of isotonic versus hypertonic saline (6.0%) in CF patients with chronic rhinosinusitis - Results of a multicenter, prospective, randomized, double-blind, controlled trial. J Cyst Fibros 2016; 15:e57-e66. [PMID: 27267518 DOI: 10.1016/j.jcf.2016.05.003] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2016] [Revised: 04/27/2016] [Accepted: 05/02/2016] [Indexed: 11/23/2022]
Abstract
BACKGROUND Chronic rhinosinusitis is a hallmark of Cystic fibrosis (CF) impairing the patients' quality of life and overall health. However, therapeutic options have not been sufficiently evaluated. Bronchial inhalation of mucolytic substances is a gold standard in CF therapy. Previously, we found that sinonasal inhalation of dornase alfa as vibrating aerosol reduces symptoms of chronic rhinosinusitis more effectively than NaCl 0.9% (net treatment benefit: -5.87±2.3 points, p=0.017; SNOT-20 total score). This multicenter study compares the effect of NaCl 6.0% vs. NaCl 0.9% following the protocol from our preceding study with dornase alfa. METHODS Sixty nine CF patients with chronic rhinosinusitis in eleven German CF centers were randomized to receive sinonasal vibrating inhalation of either NaCl 6.0% or NaCl 0.9% for 28days. After 28days of wash-out, patients crossed over to the alternative treatment. The primary outcome parameter was symptom score in the disease-specific quality of life Sino-Nasal Outcome Test-20 (SNOT-20). Additionally, pulmonary function was assessed, as well as rhinomanometry and inflammatory markers in nasal lavage (neutrophil elastase, interleukin (IL)-1β, IL-6, and IL-8) in a subgroup. RESULTS Both therapeutic arms were well tolerated and showed slight improvements in SNOT-20 total scores (NaCl 6.0%: -3.1±6.5 points, NaCl 0.9%: -5.1±8.3 points, ns). In both treatment groups, changes of inflammatory parameters in nasal lavage from day 1 to day 29 were not significant. We suppose that the irritating properties of NaCl 6.0% reduced the suitability of the SNOT-20 scores as an outcome parameter. Alternative primary outcome parameters such as MR-imaging or the quantity of sinonasal secretions mobilized with both saline concentrations were, however, not feasible. CONCLUSION Sinonasal inhalation with NaCl 6.0% did not lead to superior results vs. NaCl 0.9%, whereas dornase alfa had been significantly more effective than NaCl 0.9%.

Abstract
The purpose of this study was to develop a paranasal sinus CT scoring system that could be used as a diagnostic tool to discriminate cystic fibrosis (CF) patients from control patients examined for sinonasal disease. The model should include as few and easily applicable criteria as possible, supported by statistical analyses and clinical judgement. We used data from 116 CF and 136 control patients. The CF patients were grouped according to the number of confirmed CF mutations: genetically verified (CF-2), or based on sweat testing and clinical findings alone (CF-1, CF-0). Nine paranasal sinus CT criteria, including development, pneumatisation variants and inflammatory patterns, were evaluated. The final model included three criteria: (a) frontal and (b) sphenoid sinus development, and (c) absence of three pneumatisation variants. This model discriminated CF-2 from controls with overlap of summed scores in only 8 of 206 patients. When this model was applied in the CF-1 and CF-0 groups, two populations seemed to exist. A larger group with summed scores overlapping that of the CF-2 group and a smaller group with summed scores overlapping that of the control group. We conclude that this CT scoring system may support, as well as exclude, a CF diagnosis in cases of diagnostic uncertainty.
