AbstractObjectiveCritical components of the nasal endoscopic examination have not been definitively established for either the normal examination or for clinical disorders. This study aimed to identify concordance among rhinologists regarding the importance of examination findings for various nasal pathologies.Study DesignA consortium of 19 expert rhinologists across the United States was asked to rank the importance of findings on nasal endoscopy for 5 different sinonasal symptom presentations.SettingAn online questionnaire was distributed in July 2023.MethodsThe questionnaire utilized JotForm® software and featured 5 cases with a set of 4 identical questions per case, each covering a common indication for nasal endoscopy. Rankings were synthesized into Normalized Attention Scores (NASs) and Weighted Normalized Attention Scores (W‐NASs) to represent the perceived importance of each feature, scaled from 0 to 1.ResultsGeneral concordance was found for examination findings on nasal endoscopy within each case. The perceived features of importance differed between cases based on clinical presentation. For instance, in evaluating postnasal drip, the middle meatus was selected as the most important structure to examine (NAS, 0.73), with mucus selected as the most important abnormal finding (W‐NAS, 0.66). The primary feature of interest for mucus was whether it was purulent or not (W‐NAS, 0.67). Similar analyses were performed for features in each case.ConclusionThe implicit framework existing among rhinologists may help standardize examinations and improve diagnostic accuracy, augment the instruction of trainees, and inform the development of artificially intelligent algorithms to enhance clinical decision‐making during nasal endoscopy.

Objective To investigate the prevalence of eustachian tube dysfunction (ETD) in elderly adults in the United States and its association with other upper aerodigestive inflammatory processes. Study Design Cross‐sectional study. Setting Population based. Subjects and Methods In total, 147,805 patients without malignancy were compared to 13,804 demographically matched patients with malignancy of the upper aerodigestive tract (UADT) by querying the Surveillance, Epidemiology, and End Results (SEER)–Medicare linked database for patients aged 66 to 99 years between 2003 and 2011. The prevalence of ETD and inflammatory diseases among these patients was compared. Association between ETD, other upper aerodigestive inflammatory processes, and UADT malignancies was evaluated. Results The prevalence of ETD was 5.44% among patients without malignancy and 9.08% in those with cancer (odds ratio [OR], 1.73; 95% CI, 1.63‐1.84). Patients with ETD in the control population were more likely (OR, 95% CI) to be diagnosed with chronic rhinitis (5.00, 4.70‐5.33), chronic sinusitis (4.20, 3.98‐4.43), allergic rhinitis (4.27, 4.08‐4.47), and gastroesophageal reflux disease (GERD) (2.42, 2.31‐2.53). Patients with ETD and chronic rhinitis (1.43, 1.24‐1.65), chronic sinusitis (1.57, 1.38‐1.78), and acute otitis media (1.33, 1.08‐1.65) were associated with higher rates of UADT malignancy. Conclusion Over 5% of patients older than 65 in the United States are diagnosed with ETD in the absence of UADT malignancy. Associations between ETD and chronic rhinitis, chronic sinusitis, allergic rhinitis, and GERD in the absence of UADT malignancy suggest that some patients may benefit from treatment of inflammatory disease as a cause of ETD.

Asthma has been implicated as a driving force in lower airway remodeling; however, its effect on upper airway development has not been studied. Clinical disease, particularly cystic fibrosis (CF), has been associated with anatomical paranasal sinus variation, although the mechanism for these variations remains unclear. The purpose of this study was to determine whether asthma is associated with altered sinus pneumatization. Five hundred ninety-one computed tomography scans, including 303 adolescents (age 13-18) and 288 adults (age > 18), were evaluated using the Assessment of Pneumatization of the Paranasal Sinuses (APPS) instrument. The APPS score is validated for assessing anatomical variation and total sinus volume. A diagnosis of asthma was ascertained from the medical record, and patients with CF were included as a positive control group. Patients with asthma had mean APPS score of 9.66, compared to 9.85 for participants without asthma ( P = .585). Subgroup analysis demonstrated similar findings among adults ( P = .817) and adolescents ( P = .585). Patients with a diagnosis of CF had significant sinus hypoplasia according to a mean APPS scores of 3.50 ( P < .001). Sinus hypoplasia persisted in both adults ( P < .001) and adolescents ( P < .001) with CF. The presence of asthma is not associated with altered paranasal sinus pneumatization. In contrast, CF is associated with significantly reduced sinus pneumatization. These findings suggest that aberrant sinus pneumatization may not be a feature of asthma and that chronic mucosal respiratory disease is not a generalizable cause for altered paranasal sinus pneumatization.

Background Chronic rhinosinusitis (CRS) and allergic rhinitis (AR) may be associated with an increased risk of subsequent diagnosis of nasopharyngeal carcinoma (NPC) or paranasal sinus cancer (PSC) in elderly Americans. The clinical utility of this association remains uncertain. Objective To compare early computed tomography (CT) or nasal endoscopy (NE) with late diagnostic studies for the diagnosis of NPC or PSC in elderly Americans with CRS or AR. Methods The Surveillance, Epidemiology, and End Results (SEER)-Medicare database was queried from 2003 to 2011 and included 150 088 Medicare beneficiaries. Patients with a diagnosis of CRS or AR were examined for either NE or CT performed within 6 months of the exposure diagnosis. The risk of a cancer diagnosis was determined between the early and the late diagnostic groups. Results The relative risk of early cancer diagnosis with NE was 1.98 (95% confidence interval [CI], 1.60–2.43). The number needed to detect (NND) a case of cancer with NE was 503 (95% CI, 387–718). The relative risk of an early cancer diagnosis using CT was 3.40 (95% CI, 2.85–4.06) and NND was 221 (95% CI, 194–255). The stage of NPC or PSC for the late diagnostic group was not different from those with early NE ( P = .458) or CT ( P = .497). Overall survival was not different between diagnostic groups for NE ( P = .789) or CT ( P = .425). Conclusions Early NE or CT is associated with a higher likelihood of cancer diagnosis in elderly individuals with a diagnosis of CRS or AR. The clinical utility of this association is limited due to the low prevalence of these malignancies and lack of difference in disease stage and overall survival between diagnostic groups.

AbstractBackgroundAn association is suggested between gastroesophageal reflux disease (GERD) or laryngopharyngeal reflux (LPR) and malignancy of the larynx in elderly patients in the United States. Early detection with flexible fiberoptic laryngoscopy (FFL) or CT remains poorly defined.MethodsThe Surveillance, Epidemiology, and End Results (SEER)‐Medicare linked database was queried from 2003 to 2011.A case‐cohort design evaluated patients aged 66 and older with a diagnosis of GERD and/or LPR for the occurrence of FFL or CT within 6 months of the exposure diagnosis.ResultsOf a total 156 426 Medicare beneficiaries, the relative risk of early cancer diagnosis with FFL was 14.61(95% confidence interval [CI], 13.59‐15.70), corresponding to a number needed to detect (NND) a case of cancer of 13(95% CI, 13‐14). The relative risk of an early cancer diagnosis with CT was 31.83 (95% CI, 29.57‐34.26), with a NND of 5 (95% CI, 5‐5).ConclusionsEarly FFL and CT are associated with a higher likelihood of laryngeal cancer diagnosis in elderly individuals with a diagnosis of reflux. Screening trials are necessary to establish this relationship.
