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., Level of Evidence: 4 Laryngoscope, 129:788-793, 2019., (© 2018 The American Laryngological, Rhinological and Otological Society, Inc.)

Objective: To evaluate differences in sinus surgery rates in the US Medicaid population by ethnicities., Study Design: Retrospective administrative database analysis., Setting: US-based outpatient settings., Methods: All patients from the MarketScan Medicaid database with endoscopic sinus surgery from 2009 to 2013 were stratified by ethnicity, age (5-year increments, as per US Census), and sex. Crude rates of endoscopic sinus surgery per age group and sex were compiled for all patients and each ethnic group (African American, Caucasian, Hispanics, and others). Age and sex standardization was done with the MarketScan Medicaid overall population as standard. The coefficient of variation, extremal ratio, and chi-square statistics were calculated to determine variation across ethnicities., Results: Overall sinus surgery rates per 1000 people in the Medicaid population ranged from 0.36 to 0.40 from 2009 to 2013 (African Americans: 0.24-0.26; Hispanics: 0.21-0.37; Caucasians: 0.47-0.56; rate of surgery statistically lower for African American vs Hispanics for 4 of 5 years). The coefficient of variation and extremal ratio ranged from 29.3% to 45.6% and 1.98 to 2.6, respectively. Differences among groups were significant for all years (P < .0001). Comparison of sex-adjusted ratios by age group demonstrated greater rates of surgery in the Caucasian group versus other groups for all age categories., Conclusion: The Medicaid database was selected for this analysis to eliminate payer and wealth as potential confounders in access to health care. Despite this approach, significant differences in surgery rates among ethnic groups were observed. Further research is critical to understand those differences and provide actionable and effective recommendations for change., (© American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.)

Introduction: Use of balloon catheter dilation in the management of paranasal sinus diseases, including chronic rhinosinusitis (CRS) and recurrent acute rhinosinusitis, remains controversial. In an effort to gain some clarity about its evolving role, we surveyed members of the American Rhinologic Society (ARS)., Method: Online survey., Results: ARS Members were sent an invitation by e-mail to participate in an online, anonymous 23-item survey. A total of 231 participants completed the survey, for an overall response rate of 25%. Balloon catheter technology (BCT) played no role in the practices of one-third of all the respondents. Of those who did use BCT, more than 50% performed only 1-4 cases per month on average. This did not differ significantly with practice type (p = 0.2988). The overall use of BCT differed between types of practices with those in private practice reporting greater use of the technology for maxillary and sphenoid sinuses (p = 0.0003 and p = 0.0073, respectively). Participants in private practice appeared significantly more impressed with the results of BCT when compared with those in academia (p = 0.0005) and also thought that patients were more satisfied (p = 0.0002). Opinions toward the strength of available evidence also differed significantly between the two groups (p = 0.0007). Thirty-two respondents had experienced a complication with BCT, although the majority of these did not require any intervention., Conclusions: ARS members surveyed used BCT infrequently in their practices. Attitudes on the role of this technology in CRS management differed between academic and private practitioners, but, despite this, the volume of reported BCT use was the same. Surgeons are more accepting of the technology now compared with 5 years ago, and many of them believe that their use of BCT will increase in the future.
