Circulating tumor HPV DNA assessments after surgery for human papilloma virus-associated oropharynx carcinoma.

PURPOSE: To understand the utility of circulating tumor human papillomavirus DNA (ctHPVDNA) blood testing for HPV-associated oropharynx squamous cell carcinoma (HPV + OPSCC) after definitive surgery. MATERIALS AND METHODS: Prospective cohort study of HPV(+)OPSCC patients with ctHPVDNA test data to assess its accuracy in detecting biopsy-confirmed disease at various post-treatment time points. Eligible patients had p16(+)/HPV(+) OPSCC and ctHPVDNA testing performed at any time pre-operatively and/or postoperatively. In cases of recurrence, patients were excluded from analysis if ctHPVDNA testing was not performed within 6 months of biopsy. RESULTS: 196 all-treatment-type patients had at least one PT ctHPVDNA test. The initial post-treatment (PT) ctHPVDNA sensitivity, specificity, PPV, and NPV were 69.2 % (9/13), 96.7 % (177/183), 60.0 % (9/15), and 97.8 % (177/181). 61 surgery alone (SA) patients underwent 128 PT tests. The initial PT SA ctHPVDNA sensitivity, specificity, PPV, and NPV were 100 % (2/2), 96.0 % (48/50), 50 % (2/4), and 100 % (48/48). 35 of 61 (57.4 %) SA patients had NCCN-based histopathologic indications for adjuvant (chemo)radiation but declined. 3 of 35 (8.57 %) had a positive PT ctHPVDNA test of which 1 of 3 (33 %) had biopsy-proven recurrence. Prospectively, ten patients had a PreT positive ctHPVDNA, underwent SA, refused adjuvant treatment, had an undetectable ctHPVDNA within 2 weeks of SA, and remained free of disease (mean 10.3 months). CONCLUSION: The high specificity and NPV of ctHPVDNA after SA suggest ctHPVDNA may have a role in determining the omission of PT adjuvant (chemo)radiation in select patients.

The diagnostic dilemma of identifying perforated appendicitis.

BACKGROUND: Despite extensive research, the classification of perforated (PA) versus nonperforated appendicitis (NPA) remains poorly defined. We hypothesize that the variability across specialties in the classification of appendicitis as PA or NPA may be associated with variation in clinical behavior as demonstrated by a variation in length of stay (LOS). METHODS: Retrospective review of 1311 appendectomies over a 16-mo period from an independent children's hospital allowed a comparison of the diagnostic classification of appendicitis as PA or NPA based on radiology (R), operative (O), and pathology (P) reports. Three groups, P + O (n = 1241), P + R (n = 516), O + R (n = 512) were compared to identify interspecialty discordance in classification. The LOS was analyzed as a proxy for clinical behavior to test if the diagnostic classification was consistent with expected clinical behavior (NPA with LOS ≤48 h and PA with LOS >48 h). RESULTS: The subsets P + O, P + R, and O + R revealed a discordance of 11%, 15.7%, and 16.6% within the classification of appendicitis, respectively. Cases designated as PA in all subsets clinically behaved as PA with a mean LOS >48 h (97, 95, and 95 h, respectively), whereas the cases designated as NPA exhibited greater variation from the expected LOS ≤48 h, with means 35, 83, and 62 h, respectively. CONCLUSIONS: Variability in the classification of appendicitis between specialties suggests an error rate inherent in diagnosis. Standardizing the criteria for classification across specialties may improve the diagnostic accuracy of the type of appendicitis needed to identify best practices for optimal use of hospital resources and for meaningful clinical trials.

Finding the Potholes in Academic Career Pathways for Underrepresented Groups in Otolaryngology.

OBJECTIVE: To assess inequities in representation among ranks and odds of promotion by race in academic otolaryngology. STUDY DESIGN: Cross-sectional study. SETTING: US academic medical centers. METHODS: Demographic data was collected for medical students, residents, and faculty in the Association of American Medical Colleges and Accreditation Council for Graduate Medical Education databases for the academic year 2020 to 2021. The rank equity index (REI) was used to make pairwise comparisons between ranks to determine groups' representation between levels. Odds ratios (ORs) and 95% confidence intervals (CIs) demonstrating the likelihood that an individual of a particular rank/race would advance in their academic career were determined. RESULTS: Representation comparing medical students with full professors for black, Latine, and Asian otolaryngologists was below parity (REI: 0.27, 0.85, 0.85, respectively). Black (OR: 0.20, CI: 0.15, 0.26), Latine (OR: 0.61, CI: 0.50, 0.75), and Asian (OR: 0.62, CI: 0.55, 0.71) medical students all faced lower odds of becoming otolaryngology residents compared to their white counterparts. Similar findings occurred when comparing resident and assistant professor representation. American Indian/Alaskan Native (AIAN) and Native Hawaiian/Pacific Islander (NHPI) REIs and ORs could not be assessed as only 1 self-reported AIAN and no NHPI faculty are present in the studied data. CONCLUSION: Underrepresented in Medicine and Asian physicians faced worsening representation at each rung of the academic otolaryngology ladder. The greatest losses occurred when medical students transitioned to residents and residents transitioned to assistant professors. AIAN and NH faculty were absent in otolaryngology, indicating vital targets for recruitment efforts.

The Toxicological Effects of e-Cigarette Use in the Upper Airway: A Scoping Review.

OBJECTIVE: While evidence continues to emerge on the negative health effects of electronic cigarettes (e-cigarettes) on the lungs, little is known regarding their deleterious effects on the upper airway. The purpose of this review is to summarize the toxicological effects of e-cigarettes, and their components, on the upper airway. DATA SOURCES: PubMed, SCOPUS, EMBASE databases. REVIEW METHODS: Systematic searches were performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines from 2003 to 2023. Studies were included if they investigated the toxicological effects of e-cigarette exposure on human or animal upper airway tissue. Two authors independently screened, reviewed, and appraised all included articles. RESULTS: A total of 822 unique articles were identified, of which 53 met inclusion criteria and spanned subsites including the oral cavity (22/53 studies), nasal cavity/nasopharynx (13/53), multiple sites (10/53), larynx (5/53), trachea (2/53), and oropharynx (1/53). The most commonly observed consequences of e-cigarette use on the upper airway included: proinflammatory (15/53 studies), histological (13/53), cytotoxicity (11/53), genotoxicity (11/53), and procarcinogenic (6/53). E-cigarette humectants independently induced toxicity at multiple upper airway subsites, however, effects were generally amplified when flavoring(s) and/or nicotine were added. Across almost all studies, exposure to cigarette smoke exhibited increased toxicity in the upper airway compared with exposure to e-cigarette vapor. CONCLUSION: Current data suggest that while e-cigarettes are generally less harmful than traditional cigarettes, they possess a distinct toxicological profile that is enhanced upon the addition of flavoring(s) and/or nicotine. Future investigations into underexamined subsites, such as the oropharynx and hypopharynx, are needed to comprehensively understand the effects of e-cigarettes on the upper airway.

"Left on their own": Left-handedness among rhinologists and otolaryngology trainees.

KEY POINTS: Left-hand-dominant (LHD) respondents reported higher rates of training difficulties because of handedness differences. LHD respondents cited particular difficulty with functional endoscopic sinus surgery. Both LHD and right-hand-dominant respondents perceived a need for laterality-specific training during residency.

Limitations in Faculty Advancement for Underrepresented Groups in Academic Otolaryngology.

OBJECTIVE: Despite the increasing racial diversity of the United States, representation in academic medicine faculty does not reach concordance with the general population and worsens with higher rank. Few studies have examined this within academic Otolaryngology and surgical subspecialties. This project aims to compare rank equity in academic Otolaryngology on self-reported gender and race/ethnicity between the years 2000 and 2020. METHODS: Publicly available data were obtained from the Association of American Medical Colleges under the "Data & Reports" section for the years 2000 and 2020. The report comprised of full-time faculty from all U.S. medical schools. To determine parity between faculty ranks across gender and race/ethnicity, rank equity index (REI) was calculated for associate/assistant, professor/associate, and professor/assistant professor comparisons. RESULTS: The percentage of women faculty in Otolaryngology has increased from 21% in 2000 to 37% in 2020; however, they did not achieve parity at all rank comparisons for both years. On the contrary, men were above parity at all rank comparisons. Improvements in rank equity occurred for Black/African American (Black) and Hispanic Latino/Spanish Origin (Latine) faculty between the years 2000 and 2020; however, when accounting for gender, benefits were concentrated among men. CONCLUSION: Advancement along the academic ladder is limited for women of all racial groups in academic Otolaryngology. While improved rank equity was seen for Black and Latine faculty, these improvements were largely among men. Future directions should aim to identify barriers to recruitment, retention, and promotion for women and underrepresented in medicine (URiM) academic otolaryngologists and create interventions that diversify Otolaryngology faculty at all ranks.

Outcomes in Pediatric Endoscopic Skull Base Surgery: A Systematic Review.

Objectives The frequency of endoscopic skull base surgery in pediatric patients is increasing. This study aims to systematically review the literature for endoscopic skull base surgery outcomes in children/adolescents aged 0 to 18 years. Design A systematic review of the literature was performed in PubMed and SCOPUS databases querying studies from 2000 to 2020 using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Final inclusion criteria included: case series with more than 10 patients with pediatric patients aged ≤18 years, endoscopic or endoscopic-assisted skull base surgery, and outcomes reported. Setting This study was conducted at a tertiary care medical center. Participants Children/adolescents aged 0 to 18 years who underwent endoscopic skull base surgery were participated in this study. Main Outcome Measures Patient demographics, pathology, reconstructive technique, intraoperative findings, intraoperative, and postoperative surgical complications were measured through this study. Results Systematic literature search yielded 287 publications. Of these, 12 studies discussing a total of 399 patients aged 0 to 18 years met inclusion criteria for final analysis. Seven of the 12 studies discussed a single pathology. The most common pathology was a skull base defect causing cerebrospinal fluid (CSF) leak. The majority of skull base repairs were made with free tissue grafts. The most common postoperative complication was CSF leak ( n = 40). Twelve cases of meningitis occurred postoperatively with two of these episodes resulting in death. Conclusion Endoscopic skull base surgery has been performed recently in the pediatric population in a variety of disease states. Inconsistent individual-level data and reporting standards are present in existing studies posing challenges for comparative analysis. Standardized reporting will aid future reviews and meta-analysis for rare skull base pathology.

Effect of Application Screening Methods on Racial and Ethnic Diversity in Otolaryngology.

Otolaryngology-head and neck surgery (OHNS) lags behind other surgical subspecialties in the representation of underrepresented minorities in medicine (URMs). Given the recently announced changes to Step 1 scoring, we aimed to assess the effect of alternative application screening methods-Step 2 Clinical Knowledge scores and Alpha Omega Alpha membership-on the racial/ethnic diversity of the OHNS applicant pool. After reviewing OHNS residency applications submitted to our institution for the 2015-2020 matches (N = 2177), we determined that a significantly greater proportion of URM vs non-URM applicants would be screened out from interview consideration if any the following were used as an initial screening method: Step 2 cutoff score of 240, Step 2 cutoff score of 253 or non-Alpha Omega Alpha membership (P < .01 for each). Given that using these metrics to screen applications disproportionately affects URMs, programs should consider implementing alternative application review methods, such as holistic evaluation, which may promote more equitable distribution of interviews.

Availability of Readable Online Spanish Rhinosinusitis Outcome Measures.

BACKGROUND: Patient-reported outcome measures (PROMs) are useful instruments that give providers insight into patients' experiences with disease by quantifying the symptoms that matter most to patients. Results of these questionnaires can help guide management in chronic rhinosinusitis. However, these tools are often developed for native English speakers, which disadvantages others, who already have a language barrier to care. The aim of this study is to evaluate accessibility and readability of Spanish PROMs used to evaluate rhinosinusitis. METHODS: Three Spanish readability measures, Gilliam, Peña & Mountain; SOL; and Fernandez-Huerta were used to evaluate PROMs utilized for rhinosinusitis. PROMs with sixth-grade readability level or easier were considered to meet health literacy recommendations. RESULTS: Four Spanish PROMs utilized in assessment of rhinosinusitis were identified and evaluated. Cuestionario Español de Calidad de Vida en Rinitis (ESPRINT-15) was the most readable PROM and met readability recommendations in two of three measures. Nasal Obstruction Symptom Evaluation met suggested levels in one measure. The remainder of readability scores were more difficult than recommended. CONCLUSION: PROMs are powerful clinical tools that help patients communicate their symptoms and self-advocate. For providers to gain accurate and useful information, these measures should be written at appropriate readability levels. Most Spanish PROMs used for assessment of rhinosinusitis were above recommended readability. Development of future PROMs should ensure appropriate readability levels to provide good patient-centered care for our primarily Spanish speaking patients.

Long-Term Academic Outcomes of Triological Society Research Career Development Award Recipients.

OBJECTIVES/HYPOTHESIS: Each year, the Triological Society awards several Research Career Development Awards (CDAs) to support early-career otolaryngologists. The objective of this study was to evaluate academic outcomes of CDA recipients including National Institutes of Health (NIH) funding acquisition and h-index. A secondary objective was to appraise gender differences in outcomes among awardees. STUDY DESIGN: Cross-sectional study. METHODS: Recipients' practice setting, degree type, academic rank, and leadership titles were determined through review of academic and private practice profiles in October 2019. NIH funding was assessed using the NIH Research Portfolio Online Reporting Tool and the h-index was calculated using the Scopus database. RESULTS: Between 2004 and 2019, 70 investigators received a CDA. Of the 65 awardees prior to 2019, 26 (40.0%) obtained NIH grants after the CDA. Having an MD/PhD or MD/master's was not associated with NIH funding attainment (P = .891) nor with higher funding total (P = .109). However, funding total was significantly higher for full professors compared to assistant professors (P = .022). The median h-index among awardees was 16 (interquartile range = 11-21) and differed significantly by academic rank (P < .001). Moreover, 23 CDAs (32.9%) were awarded to women. However, fewer female recipients obtain NIH funding after the CDA compared to men (10.5% vs. 52.2%, P = .002), and they had significantly lower h-indices than men (10 vs. 17, P < .001). CONCLUSIONS: As a cohort, CDA awardees achieve higher academic success than academic otolaryngologists in general. However, female CDA recipients lag behind their male colleagues, highlighting the need for more research to uncover contributors to gender differences and ways to foster equity in research.

Readability analysis of pediatric otolaryngology patient-reported outcome measures.

OBJECTIVE: (s): Patient-reported outcome measures (PROMs) are tools that allow patients to directly share information about their health with their healthcare provider. Health literacy experts recommend that health information, such as PROMs, be written at a 6th grade level to ensure patients can read and comprehend it. As the readability of PROMs used in pediatric otolaryngology has yet to be studied, our goal was to analyze the readability of these PROMs and assess their compliance with readability recommendations. METHODS: The Gunning Fog, the Simple Measure of Gobbledygook (SMOG), and the FORCAST readability formulas were used to determine the readability of disease-specific PROMs for pediatric otolaryngology. RESULTS: Fourteen PROMs were reviewed in the study. Most were intended for caregiver completion (n = 13, 92.9%). Ten PROMs when measured by Gunning Fog (71.4%), 2 PROMs when measured by SMOG (14.3%), and 0 PROMs when measured by FORCAST (0.0%) were at or below the 6th grade reading level. CONCLUSION: Most PROMs available for use in pediatric otolaryngology are above the recommended 6th grade reading level when measured by FORCAST, the most appropriate metric for assessing questionnaires. The high reading grade level needed to complete these PROMs can contribute to health disparities among underserved and vulnerable populations, such as children. Pediatric otolaryngology PROMs developed in the future should take readability into account in order to ensure equity in the delivery of care.

Recent Trends in Female and Racial/Ethnic Minority Groups in U.S. Otolaryngology Residency Programs.

OBJECTIVES: Our objectives were to analyze the recent trends in applicants of otolaryngology-head and neck surgery (Oto-HNS) residency programs, including evolutions in sex and racial/ethnic distribution within the applicant pool and subsequent residency cohort. METHODS: Retrospective database and literature review. Data regarding applicants to Oto-HNS programs as well as Oto-HNS residents in the United States from 2008 to 2017 were analyzed from the Electronic Residency Application Service, National Resident Matching Program, and Journal of the American Medical Association. RESULTS: Between 2008 and 2018, the number of Oto-HNS residency programs and residency positions offered increased from 105 to 112 and from 273 to 315, respectively. There was no statistically significant difference between applicant sex in 2008 to 2012 compared to 2013 to 2018 (P > .05), but significantly more females made up the residency workforce from 2013 to 2018 compared to 2008 to 2012 (P < .001). However, the percentage increase in female residents from 2008 to 2017 was only 6.1% (29.8% to 35.9%). No statistically significant difference was present between applicant race in 2008 to 2012 compared to 2013 to 2018 (P > .05), but significantly more minority residents made up the residency workforce from 2013 to 2018 compared to 2008 to 2012 (P < .0001). However, the percentage increase in minority residents from 2008 to 2017 was only 4.9% (35.1% to 40%). CONCLUSION: Women and minority racial and ethnic groups continue to be underrepresented among Oto-HNS applicants. However, the presence of these groups among current residents has increased. Understanding and tracking these national trends yearly is critical for training a diverse future otolaryngology workforce. LEVEL OF EVIDENCE: VI Laryngoscope, 131:277-281, 2021.

HPV in the malignant transformation of sinonasal inverted papillomas: A meta-analysis.

OBJECTIVES: To date, there is still a significant debate on the role of human papilloma virus (HPV) infection in transformation of inverted papillomas (IPs) to squamous cell carcinoma (SCC). This study was designed to determine if the presence of HPV in a sinonasal IP increases the risk of malignant transformation to IPSCC. METHODS: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, 19 high-quality case-control and cohort studies with tissue-diagnosed IP or IPSCC and HPV diagnosis were analyzed. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using the Mantel-Haenszel method with correction for random effects. Subgroup, publication bias and a sensitivity analyses were also performed. RESULTS: Nineteen studies with minimal bias met the inclusion criteria for quality and identified HPV infection in an IP. The pooled data revealed a strong association with progression to malignancy with an unweighted, pooled OR of 2.38 (CI95 1.47 to 3.83) and a weighted OR of 2.80 (CI95 1.42 to 5.51). Sensitivity analysis revealed that no single study contributed significantly to our pooled OR calculations (ORs 2.52 to 3.57). Subgroup analyses stratified by publication date, nucleic acid target, HPV detection method and type, sample size, and region all demonstrated a positive association of HPV with IPSCC. CONCLUSIONS: There appears to be a significant association between HPV infection and malignant transformation of IPs. While HPV testing is not currently the standard of care for IPs, these data suggest a link between the two and suggest further studies should be performed to identify a link between the virus and malignant transformation.

Radiologic Analysis of Balloon Sinuplasty in a Human Cadaver Model: Observed Effects on Sinonasal Anatomy.

BACKGROUND: Balloon sinuplasty is increasingly used in the outpatient clinic for treatment of chronic rhinosinusitis, but radiologic analysis of its effects on sinonasal anatomy is largely uncharacterized in the known literature. OBJECTIVE: The purpose of this study is to examine the anatomic effects of balloon sinuplasty in a cadaveric model. METHODS: Five fresh cadaver heads underwent sequential endoscopic balloon dilation of maxillary ostia, frontal recess outflow tracts, and sphenoid ostia bilaterally by fellowship-trained rhinologists. Pre- and post-procedural CT imaging was obtained. CT scans were imported into Mimics™ software and sinonasal anatomy was analyzed systematically. RESULTS: Visual confirmation of balloon dilation was achieved in all 3 sites bilaterally in each cadaver. Radiologic analysis demonstrated that the frontal sinus outflow tract was appropriately dilated 60% (6/10 sites) of the time while the agger was inadvertently dilated 30% of the time (3/10). The sphenoid os was successfully dilated 70% (7/10 sites) of the time. In two cases, a posterior sphenoethmoid (Onodi) cell was dilated instead of the sphenoid. Successful dilation of maxillary os was noted 60% of the time (6/10 sites). No significant change in maxillary os was noted after balloon dilation. Normal middle turbinates were significantly medialized following balloon dilation 75% (6/8 sites) of the time. CONCLUSIONS: While the goal of balloon sinuplasty is to improve natural sinonasal drainage by dilating existing outflow tracts, as evidenced by radiologic evaluation the procedure appears not to achieve this in all cases, while occasionally creating unintended changes in sinonasal anatomy as well. These unrecognized changes in anatomy may be responsible for the post-procedure change in symptomatology that some patients experience.

Readability of Patient-Reported Outcome Measures for Head and Neck Oncology.

OBJECTIVES/HYPOTHESIS: Patient-reported outcome measures (PROMs) are communication tools to help patients convey their disease experience to medical providers and guide management decisions. However, the utility of healthcare outcome measures is dependent on patient literacy and readability of PROMs. If written for a more advanced literacy level, they can misestimate symptoms and add significant barriers to care, especially in the underserved. However, readability of head and neck (H&N) oncology PROMs has not been assessed. The aim of this study was to evaluate the readability of H&N oncology PROMs to assess whether they meet recommended readability levels. STUDY DESIGN: Bibliometric review. METHODS: Three readability measures: Gunning Fog, Simple Measure of Gobbledygook, and FORCAST were used to evaluate the readability level of commonly used H&N PROMs. PROMs with sixth grade readability level or lower were considered to meet the recommendations of health literacy experts. RESULTS: Eight H&N oncology PROMs were reviewed. None of H&N PROMs met health literacy experts' and National Institutes of Health recommended reading levels. Gunning Fog consistently estimated easiest readability and FORCAST the most difficult. CONCLUSIONS: PROMs are important clinical tools that drive patient-centric care in H&N oncology. All H&N PROMs are written above recommended reading levels and do not meet suggested standards. Future PROMs should be written with easier readability to accurately convey patients' H&N oncology disease experiences. LEVEL OF EVIDENCE: 4 Laryngoscope, 2020.

Readability of patient-reported outcome measures for chronic rhinosinusitis and skull base diseases.

OBJECTIVE: Outcome measures in healthcare that presume a higher level of patient health and overall literacy may inadequately estimate the disease experiences of less-educated patients and further disadvantage them. Patient-Reported Outcome Measures (PROMs) are widely used communication tools for clinical practice and are often used to evaluate and guide management for chronic rhinosinusitis (CRS) and skull base diseases. However, their readability and subsequent incomprehensibility for patients have not been assessed. The aim of this study is to evaluate the readability of commonly used PROMs for these conditions and whether they meet recommended readability levels. METHODS: Three readability measures, Gunning Fog, Simple Measure of Gobbledygook (SMOG), and FORCAST were used in the evaluation of commonly used PROMs for CRS and skull base disease. PROMs with sixth-grade readability level or lower were considered to meet health literacy experts' recommendations. RESULTS: A total of 11 PROMs were reviewed (8 CRS, 3 skull base). Gunning Fog consistently estimated the easiest readability, whereas FORCAST the most difficult. One hundred percent of CRS and 67% of skull base PROMs were above National Institutes of Health and health literacy experts' recommended reading levels. PROMs developed more recently had easier readability. CONCLUSION: PROMs are important clinical tools in otolaryngology that help guide management of disease for improved patient-centered care. Like many other fields of medicine, those used in otolaryngology are beyond recommended reading levels. Development of PROMs in the future should meet recommended readability levels to fully assess the disease experience of our patients. LEVEL OF EVIDENCE: 4 Laryngoscope, 130:2305-2310, 2020.

Intranasal Corticosteroids: Patient Administration Angles and Impact of Education.

INTRODUCTION: Intranasal corticosteroids sprays (INCS) are first line treatment for allergic rhinitis and are frequently used for chronic rhinosinusitis. Improperly aiming INCS increases the risk of epistaxis and may decrease the efficacy of the medication. The goal of this study was to determine how patients position INCS for drug delivery and if verbal or written instructions improve their positioning. METHODS: Patients in rhinology clinics were photographed while administering a generic spray bottle. The angle of the spray bottle relative to the patients' head and a fixed background was determined. RESULTS: A total of 46 participants were included. The average spray angle for the right naris was 10.1° towards the septum and 67.2° below the Frankfurt Horizontal plane. The average spray angle for the left naris was 4.5° towards the septum and 62.2° below the Frankfurt horizontal plane. The angle of the spray bottle ranged from 50° toward the septum to 43° away from the septum. Only 8 patients aimed away from the septum for both nares. Patients who recalled receiving verbal and written instructions aimed the INCS bottle at the lateral wall and inferior turbinate in contrast to patients who only received one form of instruction or no instructions. CONCLUSIONS: Most patients (83%) incorrectly aim INCS when compared to current guidelines. There was statistically significant improvement in the positioning of patients who reported receiving both verbal and written instruction; however, this study highlights a greater need for patient education.

Streamlining care in cystic fibrosis: survey of otolaryngologist, pulmonologist, and patient experiences.

BACKGROUND: Care coordination for cystic fibrosis (CF) is essential. The objectives of this study were to: (1) compare otolaryngologists' and pulmonlogists' understanding of long-term chronic rhinosinusitis (CRS) management; and (2) query patient perceptions of otolaryngologic care and CRS. METHODS: A cross-sectional survey was administered by the Cystic Fibrosis Foundation in 2018 to patients with CF or their caregivers, otolaryngologists, and pulmonologists. Statistical analysis was performed comparing specialists. Descriptive statistics were computed for patient/caregiver-reported data. RESULTS: Respondents included 126 otolaryngologists, 115 pulmonologists, and 186 patients with CF or their caregivers. Pulmonologists had greater experience caring for CF patients compared with otolaryngologists (66.7% vs 43.2% with 13+ years of experience, respectively), but more otolaryngologists cared for both adult and pediatric CF patients (39.2% vs 10.4%, respectively). Significantly more otolaryngologists advocated for establishing otolaryngologic care at time of CF diagnosis (64.8%) compared with pulmonologists (14.4%, p < 0.001), of whom 60.4% recommended otolaryngologist referral when sinonasal symptoms affect quality of life. More otolaryngologists perceived sinus surgery as beneficial for pulmonary function (74.5% vs 57.7%, p = 0.009); 60.8% of patients first sought otolaryngologic care in infancy or childhood (<13 years). Median number of sinus surgeries was 3 (interquartile range, 2-5). The most common perceived benefits of surgery according to patients/caregivers included improved breathing (31.2%) and improved sinonasal symptoms (23.7%). Top patients/caregiver otolaryngologic priorities included symptom/infection control (49.0%) and care coordination (15.0%). CONCLUSION: Our results highlight variable patient/caregiver experiences, and suggest that otolaryngologist and pulmonologist perceptions of CF otolaryngologic care also differ in some respects requiring improved interspecialty coordination/education.

Cystic Fibrosis Transmembrane Conductance Regulator Modulator Therapy: A Review for the Otolaryngologist.

BACKGROUND: Cystic fibrosis (CF) is a genetic disease that may result in multiple systemic disorders and potentially fatal severe respiratory compromise. However, the advent of CF transmembrane conductance regulator (CFTR) modulators has changed the management of CF for patients with select mutations. Although clinical trials have highlighted increased pulmonary function and decreased exacerbations as a result of these novel therapies, their effect on the sinuses has not been well-described. OBJECTIVE: Our objective is to review the CFTR modulators to provide otolaryngologists, physicians who frequently care for patients with CF, a basic understanding of these drugs and their effects on chronic rhinosinusitis (CRS) in patients with CF. METHODS: The clinically approved and available CFTR modulators and specific indications for their use are reviewed. Additionally, a systematic review of these therapies and effects on CRS in CF was performed. RESULTS: Four Food and Drug Administration approved CFTR modulators are available for patients with CF. Current drugs are approved for gating, residual function, or F508del mutations. Multiple reports describe CFTR modulators' increase in transepithelial ion transport in nasal epithelial cultures; however, clinical studies regarding effects of these modulators on sinonasal health are limited to 5 studies that present new data of the effects of CFTR modulators in CRS. CONCLUSIONS: CFTR modulators have changed management of CF. Initial studies of these medications demonstrate promising results in CF; however, there is a paucity of literature describing the effect of CFTR modulators on CF-associated CRS, although initial results are encouraging.

Numerical evaluation of spray position for improved nasal drug delivery.

Topical intra-nasal sprays are amongst the most commonly prescribed therapeutic options for sinonasal diseases in humans. However, inconsistency and ambiguity in instructions show a lack of definitive knowledge on best spray use techniques. In this study, we have identified a new usage strategy for nasal sprays available over-the-counter, that registers an average 8-fold improvement in topical delivery of drugs at diseased sites, when compared to prevalent spray techniques. The protocol involves re-orienting the spray axis to harness inertial motion of particulates and has been developed using computational fluid dynamics simulations of respiratory airflow and droplet transport in medical imaging-based digital models. Simulated dose in representative models is validated through in vitro spray measurements in 3D-printed anatomic replicas using the gamma scintigraphy technique. This work breaks new ground in proposing an alternative user-friendly strategy that can significantly enhance topical delivery inside human nose. While these findings can eventually translate into personalized spray usage instructions and hence merit a change in nasal standard-of-care, this study also demonstrates how relatively simple engineering analysis tools can revolutionize everyday healthcare. Finally, with respiratory mucosa as the initial coronavirus infection site, our findings are relevant to intra-nasal vaccines that are in-development, to mitigate the COVID-19 pandemic.
