Objectives The aim of the study was to identify trends in postoperative management of persons undergoing surgery for Zenker diverticula (ZD) by evaluating length of stay (LOS), diet on discharge, and imaging with or without surgical complication. Methods Prospectively enrolled adult patients with cricopharyngeal muscle dysfunction with diverticula undergoing surgery from August 1, 2017 to February 1, 2023 were included. Data were extracted from a multi‐institutional REDCap database, summarizing means, medians, percentages, and frequencies. Fisher's exact or chi squared analyses were utilized, as appropriate, to compare subsets of data. Descriptive analysis assessed differences in clinical course and the relationship to postoperative management. Results There were 298 patients with a mean (standard deviation) age of 71.8 (11.2) years and 60% male. Endoscopic surgery was performed in 79.5% (237/298) of patients versus 20.5% (61/298) open surgery. Sixty patients (20.1%) received postoperative imaging, with four leaks identified. Complications were identified in 9.4% of cases ( n = 29 complications in 28 patients), more commonly in open surgery. Most (81.2%) patients were discharged within 23 h. About half of patients (49%) were discharged from the hospital on a pureed/liquid diet; 36% had been advanced to a soft diet. In patients without complications, LOS was significantly longer following open cases ( p = 0.002); postoperative diet was not different between open and endoscopic ( p = 0.26). Conclusions Overall, most patients are discharged within 23 h without imaging. However, LOS was affected by surgical approach. Postoperative complications are different in endoscopic versus open surgery. Complications with either approach were associated with prolonged LOS, need for imaging, and diet restriction.

ObjectiveTo compare improvement in patient‐reported outcomes (PROM) in persons undergoing endoscopic and open surgical management of Zenker diverticula (ZD).MethodologyProspective, multicenter cohort study of all individuals enrolled in the Prospective OUtcomes of Cricopharyngeus Hypertonicity (POUCH) Collaborative who underwent surgery for ZD. Patient survey, radiography reports, and the 10‐item Eating Assessment Tool (EAT‐10) pre‐ and post‐procedure were abstracted from a REDCap database, which summarized means, medians, percentages, and frequencies of. Outcome based on operative intervention (endoscopic vs. open) was compared using t‐test, Wilcoxon rank sum test or chi‐square test, as appropriate.ResultsOne hundred and forty‐seven persons were prospectively followed. The mean age (SD) of the cohort was 68.7 (11.0). Overall, 66% of patients reported 100% improvement in EAT‐10; 81% of patients had greater than 75% improvement; and 88% had greater than 50% improvement. Endoscopic was used for n = 109 patients, and open surgical intervention was used for n = 38. The median [interquartile range, IQR] EAT‐10 percent improvement for endoscopic treatment was 93.3% [72, 100], and open was 100% [92.3, 100] (p = 0.05). The incidence of intraoperative complications was 3.7% for endoscopic and 7.9% for open surgical management. The median [IQR] in follow‐up was 86 and 97.5 days, respectively.ConclusionBoth endoscopic and open surgical management of ZD provide significant improvement in patient‐reported outcomes. The data suggest that open diverticulectomy may provide a modest advantage in symptomatic improvement compared to endoscopic management. The data suggest that the postoperative complication rate is higher in the open surgical group.Level of Evidence3 Laryngoscope, 134:97–102, 2024

ObjectiveTo assess barium esophagram (BAS) as a diagnostic marker for patients with Killian Jamieson diverticula (KJD).MethodsProspective, multicenter cohort study of individuals enrolled in the Prospective OUtcomes of Cricopharyngeus Hypertonicity (POUCH) Collaborative. Patient demographics, comorbidities, radiographic imaging reports, laryngoscopy findings, patient‐reported outcome measures (PROM), and operative reporting were abstracted from a REDCap database and summarized using means, medians, percentages, frequencies. Paired t‐tests and Wilcoxon Signed Rank test were used to test pre‐ to post‐operative differences in RSI, EAT‐10, and VHI‐10 scores. Diagnostic test evaluation including sensitivity, specificity, positive, and negative predictive value with 95% confidence intervals were calculated comparing BAS findings to operative report.ResultsA total of 287 persons were enrolled; 13 (4%) patients were identified with confirmed KJD on operative reports. 100% underwent open transcervical excision. BAS has a 46.2% (95% confidence interval [CI]: 23.2, 70.9) sensitivity and 97.8% (95% CI: 95.3, 99.0) specificity in detecting a KJD and 50% (95% CI: 25.4, 74.6) positive predictive value but 97.4% (95%CI: 94.8, 98.7) negative predictive value. Preoperatively, patients reported mean (SD) RSI and EAT‐10 of 19.4 (9) and 8.3 (7.5) accordingly. Postoperatively, patients reported mean (SD) RSI and EAT‐10 as 5.4 (6.2) and 2.3 (3.3). Both changes in RSI and EAT‐10 were statistically significant (p = 0.008, p = 0.03).ConclusionKJD are rare and represent <5% of hypopharyngeal diverticula undergoing surgical intervention. Open transcervical surgery significantly improves symptoms of dysphagia. BAS has high specificity but low sensitivity in detecting KJD.Level of Evidence4 Laryngoscope, 133:2110–2115, 2023

ObjectiveTo determine how social media is used in the dissemination of new information within otolaryngology, and to emphasize the importance of standardizing Twitter hashtag use.MethodsBased on the 2019 SCImago journal rankings, the Twitter posts from the accounts of the top three journals covering each otolaryngology subspecialty were reviewed from August 1, 2020 to May 1, 2021. Twitter posts from the primary otolaryngology‐related academic societies were also reviewed during this timeframe. A list of hashtags was generated based on a combination of the most common otolaryngologic procedures and most commonly used hashtags in the social media space. This list was then crowd‐sourced with 10 fellowship‐trained otolaryngologists for each subspecialty.ResultsHashtag use among key stakeholders in the otolaryngology social media space varies considerably. For instance, #HNSCC, #HeadAndNeckSquamousCellCarcinoma, #HeadAndNeckCancer, #HeadAndNeckCancers, #OropharyngealCancer, #OropharynxCancer, #OralCancer, and #OPSCC were all commonly used hashtags to identify posts discussing oropharyngeal squamous cell carcinoma. #HeadAndNeckCancer and #HNSCC were most popular and used in a total of 85 and 65 tweets, respectively. #HeadAndNeckCancer was found alone in 32 out of 85 tweets (38%), whereas #HNSCC was found alone in 27 out of 65 tweets (42%). A standardized hashtag ontology covering all subspecialties within otolaryngology is proposed herein.ConclusionsAdoption of a standardized social media ontology within otolaryngology will improve information dissemination across all key stakeholders.
