Clinical Characteristics of the Cervical Inlet Patch: A Case Series.

Objective: The goal of this study was to characterize the symptoms and outcomes of patients with a symptomatic cervical inlet patch (CIP). Study Design: Retrospective case series. Setting: Tertiary care laryngology clinic in Charlottesville, Virginia. Methods: A retrospective chart review of the patient's demographics, comorbidities, prior workup, interventions, and response to treatment was performed. All patients received flexible nasolaryngoscopy and barium swallow study. The analysis was descriptive. Results: Eight patients (6 female) were followed for the management of symptoms related to CIP. The mean age at presentation to our clinic was 64.9 (standard deviation = 15.7). Five out of 8 patients presented with a chief complaint of dysphagia, and the remaining 3 with chronic coughs. Five out of 8 patients demonstrated findings of laryngopharyngeal reflux (LPR) including vocal fold edema, mucosal erythema, or postcricoid edema. Swallow study demonstrated hiatal hernia in 3 of 8 patients, and cricopharyngeal (CP) dysfunction (CP hypertrophy, CP bar, and Zenker's diverticulum) in 3 of 8 patients. One patient presented with a history of Barrett's esophagus. Treatment included increased acid suppression therapy and management of coexisting esophageal pathologies. Ablative procedures were performed in 5 out of 8 cases, with 2 patients requiring repeat procedures. All patients experience subjective symptom improvement. Conclusion: CIP tends to present in complex patients with multifactorial dysphagia, with the most common symptoms being dysphagia and cough. Clinical features of CIP overlap with other more common pathologies encountered by otolaryngologists including LPR and CP dysfunction, and future prospective studies in larger populations should seek to clarify these associations.

BPPV Information on Google Versus AI (ChatGPT).

OBJECTIVE: To quantitatively compare online patient education materials found using traditional search engines (Google) versus conversational Artificial Intelligence (AI) models (ChatGPT) for benign paroxysmal positional vertigo (BPPV). STUDY DESIGN: The top 30 Google search results for "benign paroxysmal positional vertigo" were compared to the OpenAI conversational AI language model, ChatGPT, responses for 5 common patient questions posed about BPPV in February 2023. Metrics included readability, quality, understandability, and actionability. SETTING: Online information. METHODS: Validated online information metrics including Flesch-Kincaid Grade Level (FKGL), Flesch Reading Ease (FRE), DISCERN instrument score, and Patient Education Materials Assessment Tool for Printed Materials were analyzed and scored by reviewers. RESULTS: Mean readability scores, FKGL and FRE, for the Google webpages were 10.7 ± 2.6 and 46.5 ± 14.3, respectively. ChatGPT responses had a higher FKGL score of 13.9 ± 2.5 (P < .001) and a lower FRE score of 34.9 ± 11.2 (P = .005), both corresponding to lower readability. The Google webpages had a DISCERN part 2 score of 25.4 ± 7.5 compared to the individual ChatGPT responses with a score of 17.5 ± 3.9 (P = .001), and the combined ChatGPT responses with a score of 25.0 ± 0.9 (P = .928). The average scores of the reviewers for all ChatGPT responses for accuracy were 4.19 ± 0.82 and 4.31 ± 0.67 for currency. CONCLUSION: The results of this study suggest that the information on ChatGPT is more difficult to read, of lower quality, and more difficult to comprehend compared to information on Google searches.

Evolving Endotracheal Tube Preferences and Practices: Intensivist Knowledge Gaps and Sex Disparities.

OBJECTIVES: The complex management of intubation-related laryngeal injury makes prevention vital. The purpose of this study is to assess endotracheal tube (ETT) practices and preferences among intensivists at our institution. METHODS: Chart review of intubated patients and intensivist survey were simultaneously performed in January 2016 and August 2022. A height-to-ETT size ratio (H:ETT) was calculated for each patient in the 2022 cohort. Intubated patients were followed until tracheostomy, extubation, or death occurred. Surveys assessed intensivist preferences for ETT size and management of intubated patients. RESULTS: 300 ICU patients were included. The mean ETT size for males decreased from 7.73 ± 0.30 in 2016 to 7.57 ± 0.25 in 2022 (p < 0.001). The average H:ETT of men was higher than females (p = 0.004), indicating that females in this population were intubated with larger ETTs relative to their height compared to males. Whereas the majority (66.7%) of intensivists endorse 7.0 ETTs as the standard for women, the majority (70%) of women at our institution are intubated with a 7.5 ETT or larger. Of intubated patients in the ICU, 23 (19.5%) were intubated for 11 days or longer. CONCLUSIONS: Compared to men, women are intubated with larger-than-preferred ETTs relative to height. Additionally, patients in our study were intubated for longer than preferred based on intensivist surveys, putting this population at higher risk for acute laryngeal injury (AlgI)-related laryngotracheal stenosis (LTS). Further studies should seek to identify similar trends and barriers to reducing ALgI-related LTS. LEVEL OF EVIDENCE: 3 Laryngoscope, 133:3080-3086, 2023.

"Quality, Readability, and Understandability of Online Posterior Glottic Stenosis Information".

OBJECTIVES: To assess the quality, readability, and understandability of posterior glottic stenosis (PGS) information available to patients online. METHODS: The top 50 Google search results for "posterior glottic stenosis" were categorized based on website affiliation and target audience (patient or provider). Readability was assessed using the Flesch-Kincaid Grade Level (FKGL) and the Flesch Reading Ease (FRE) scores. The DISCERN tool was used to assess quality and the Patient Education Assessment Tool for Printed Materials (PEMAT-P) was used to assess understandability and actionability. Simple descriptive statistics were used to analyze the data. RESULTS: 36 of the top 50 results were eligible for scoring. 17% (6 of 36) were classified as patient-focused while 83% (30 of 36) were provider-focused. Patient-focused materials had a higher mean FRE score (36.9) than provider-focused materials (15.5) (P < 0.001). Patient-focused materials had an average reading level of 12.5 compared to 15.8 for provider-focused materials (P < 0.001). There was a significant correlation between overall PEMAT-P and DISCERN (r = 0.63, P < 0.001), PEMAT-P understandability and DISCERN (r = 0.63, P < 0.001) and FRES and FKGL (r = -0.67, P < 0.001). From this, we can infer that higher quality sites are easier to understand but not necessarily tailored to a certain reading level. CONCLUSIONS: Shared decision making in PGS management is crucial as patients must be aware of how treatment modalities affect airway, voice, and swallowing. However, this study shows that patient targeted PGS information is limited, and the readability, quality, and understandability is generally low. We suggest the development of web pages with PGS information tailored for patient education and search optimization to make this information appear earlier in Google search results. Furthermore, future studies should seek to characterize the link between online health information and socioeconomic-based health disparities.

Differing Progression to Posterior Glottic Stenosis in Autoimmune and Idiopathic Subglottic Stenosis.

OBJECTIVES/HYPOTHESIS: We sought to characterize rates of progression to posterior glottic stenosis (PGS) from autoimmune or idiopathic subglottic stenosis. STUDY DESIGN: This was a retrospective review. METHODS: Patients from a tertiary-care laryngology practice over a 10-year period with autoimmune or idiopathic subglottic stenosis (SGS) were included. Patients with a history of prolonged intubation or other causes of iatrogenic stenosis were excluded. PGS was confirmed on videostrobolaryngoscopy recordings by a fellowship-trained laryngologist. PGS type (1-4) was also recorded. Demographic information was recorded, and if applicable, autoimmune disease type was specified. Time until PGS was recorded along with the number of interventions. Chi-squared analysis was used to compare PGS in autoimmune and idiopathic SGS. RESULTS: A total of 77 patients were identified with autoimmune (32 patients) or idiopathic (45 patients) subglottic stenosis. Autoimmune pathologies included systemic lupus erythematosus, granulomatosis with polyangiitis (GPA), rheumatoid arthritis, relapsing polychondritis, and sarcoidosis, with GPA the most common (14/32). Patients with autoimmune SGS had a higher rate of PGS (10 of 32) compared to idiopathic subglottic stenosis (1 of 45) for an odds ratio of 20 (95% CI: 2.4-166.4, P = .006). Patients with idiopathic SGS were more likely to be female (all 45 compared to 29/32 autoimmune, P = .07) and older (mean 53 (range 29-75) compared to 46 (20-82), P = .02). CONCLUSIONS: In this large patient cohort, autoimmune SGS patients were found to have a higher likelihood of developing PGS compared to their idiopathic counterparts, suggesting that counseling for this progression may be warranted.
