ABSTRACT Objective Weight loss is frequently considered a cardinal presenting symptom for patients with Zenker diverticulum (ZD). We hypothesized that weight loss in patients with cricopharyngeal muscle dysfunction (CPMD), with or without diverticula, was associated with the length of symptoms and size of diverticulum. Methods Prospective, multicenter observational study of CPMD patients with and without diverticula reporting unintentional weight loss (+WL) or no weight loss (−WL) prior to enrollment in the Prospective Outcomes of Cricopharyngeal Hypertonicity (POuCH) database. Complications and symptom response using a patient reported outcome measure, the Eating Assessment Tool (EAT‐10), were compared. Results Of 427 patients, 101 (23.6%) were +WL. Median weight loss was 14 pounds (interquartile range [IQR] 10–25). +WL cohort had a mean age of 71.5 (standard deviation [SD] 11.5) vs. 67.9 in −WL (SD 11.6, p = 0.007). Mean preoperative EAT‐10 score was 24.7 in +WL (SD 9.7) and 14.8 in −WL (SD 8.8, p < 0.0001). Higher preoperative weight loss was associated with higher preoperative EAT‐10 ( p < 0.0001, Spearman's ρ = 0.43). Size of diverticulum was associated with WL ( p = 0.003), but weight loss was highest in both large diverticula and CP bars. Duration of symptoms was not associated with weight loss ( p = 0.30). Postoperative complications in +WL and −WL patients were similar ( p = 0.78). Conclusion Unintentional weight loss is common with ZD. Patients with worse dysphagia are more likely to have more weight loss. Weight loss does not increase with the size of the diverticulum or length of symptoms. Surgery has a similar safety profile with greater improvement in dysphagia in patients reporting weight loss. Level of Evidence 3.
Surgical Nonresponders in Zenker Diverticulum and Lower Esophageal Pathology (POUCH Collaborative)
ObjectiveTo identify characteristics of patients who have poor improvement in symptoms following surgical management of Zenker Diverticulum (ZD).MethodsProspective, multicenter cohort study of all individuals enrolled in the Prospective OUtcomes of Cricopharyngeus Hypertonicity (POUCH) Collaborative who underwent surgical repair of ZD between August 2017 and January 2024. Patient demographics, esophagrams, and the 10‐item Eating Assessment Tool (EAT‐10) pre‐ and post‐procedure were obtained from a REDCap database. t‐tests, Wilcoxon rank sum tests, Chi‐square or Fisher's exact tests were used to compare the characteristics. Patients with <50% improvement in their EAT‐10 scores were deemed surgical nonresponders (SNRs). Those with ≥50% improvement in their EAT‐10 scores were deemed surgical responders (SRs).ResultsA total of 184 patients were prospectively followed after undergoing either open or endoscopic surgical management. Twenty‐two patients (12%) were deemed SNRs. Preoperative presence of a hiatal hernia was statistically significant characteristic between the SNRs (63.6%) and SRs (32.1%) (p = 0.004). Size of the ZD and history of previous ZD surgery was not a significant characteristic. The length of stay and complication rate were not statistically different between the groups.ConclusionCoexistent esophageal pathology may lead to poor symptomatic improvement following ZD surgery. Preoperative workup of other esophageal disorders is recommended to detect likely SNRs. For SNRs, further esophageal workup may be necessary to evaluate for other esophageal causes related to poor symptomatic improvement following ZD surgery.Level of Evidence3 Laryngoscope, 134:4897–4902, 2024
Postoperative Care of Zenker Diverticula: Contemporary Perspective from the Prospective OUtcomes Cricopharyngeaus Hypertonicity (POUCH) Collaborative
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.

Surgical Outcomes in Zenker Diverticula: A Multicenter, Prospective, Longitudinal Study
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
Killian Jamieson Diverticulum, the Great Mimicker: A Case Series and Contemporary Review
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
Cricopharyngeus Muscle Dysfunction and Hypopharyngeal Diverticula (e.g., Zenker): A Multicenter Study
ObjectiveTo describe demographics and imaging and compare findings and symptoms at presentation in a large cohort of persons with cricopharyngeus muscle dysfunction (CPMD) with and without hypopharyngeal diverticula.MethodologyProspective, multicenter cohort study of all individuals enrolled in the Prospective OUtcomes of Cricopharyngeal Hypertonicity (POUCH) Collaborative. Patient survey, comorbidities, radiography, laryngoscopy findings, and patient‐reported outcome measures (e.g., Eating Assessment Tool [EAT‐10]) data were abstracted from a REDCap database and summarized using means, medians, percentages, and frequencies. Diagnostic categories were compared using analysis of variance.ResultsA total of 250 persons were included. The mean age (standard deviation [SD]) of the cohort was 69.0 (11.2). Forty‐two percent identified as female. Zenker diverticula (ZD) was diagnosed in 85.2%, 9.2% with CPMD without diverticula, 4.4% with a Killian Jamieson diverticula (KJD), and 1.2% traction‐type diverticula. There were no differences between diagnostic categories in regard to age, gender, and duration of symptoms (p = 0.25, 0.19, 0.45). The mean (SD) EAT‐10 score for each group was 17.1 (10.1) for ZD, 20.2 (9.3) for CPMD, and 10.3 (9.4) for KJD. Patients with isolated CPMD had significantly greater EAT‐10 scores compared to the other diagnostic groups (p = 0.03).ConclusionZD is the most common, followed by CPMD without diverticula, KJD, and traction‐type. Patients with isolated obstructing CPMD may be more symptomatic than persons with ZD or KJD.Level of Evidence4 Laryngoscope, 133:1349–1355, 2023
Endoscopic Findings in Male Prepubertal Choir Singers
Objectives/HypothesisThe male singing voice through puberty undergoes many changes that present challenges for the singer and choral director. The purpose of this study was to discuss the endoscopic findings seen in prepubescent choir singers.Study DesignSingle‐institution prospective study.MethodsSubjects were recruited from the Cincinnati Boychoir and were described as Cooksey stage unchanged or mid‐voice I, as described by the Boychoir artistic director. Vocal history was obtained via questionnaire at the initial visit. Subjects with known laryngeal pathologies were excluded. Endoscopic laryngeal examinations were performed using videoendoscopy. During examination, each subject sang four discrete frequencies. Findings of the endoscopic exam were judged by a board‐certified pediatric otolaryngologist specializing in pediatric voice.ResultsWe evaluated 28 subjects prior to vocal maturation. Their age range was 8 to 13 years old (mean = 10.2 ± 1.2 years). The singing voice category of all 28 subjects was described as soprano vocal range by the Boychoir artistic director. The subjects had a mean of 1.7 ± 1.1 years in the Boychoir (0–5 years). None reported history of vocal issues or voice problems in the past; seven (25%) subjects had vocal fold lesions seen at one or more frequencies; 24 (85%) subjects had a posterior gap seen at one or more frequencies. Two subjects (7%) had a posterior gap at one frequency, C3 and G3, respectively. Five subjects (18%) had a posterior gap at two frequencies, seven subjects (25%) at three frequencies, and 10 subjects (36%) in all four frequencies.ConclusionsOur study aimed to describe the laryngeal examination of dedicated Boychoir singers prior to undergoing pubertal development and vocal maturation. In elite pediatric singers we found that vocal nodules are common (25%) and are not correlated with vocal symptoms. These findings may suggest that asymptomatic lesions may be more prevalent than previously thought. In these individuals, posterior glottic gap is common and can be considered a normal glottal configuration.Level of Evidence4 Laryngoscope, 131:592–597, 2021
Endoscopic posterior cricoid reduction: A surgical method to improve posterior glottic diastasis
Objectives/HypothesisDescribe the preoperative evaluation of patients with glottic diastasis who are candidates for endoscopic posterior cricoid reduction (EPCR) and their perioperative and postoperative surgical and voice outcomes, and validate the aerodynamic benefit of EPCR using computation fluid dynamics (CFD)‐based modeling from computed tomography (CT) scans.Study DesignRetrospective case series.MethodsThirteen patients who underwent EPCR were followed from 2013 to 2017. They received a preoperative voice evaluation, microlaryngoscopy and bronchoscopy, dynamic voice CT (performed on patients seen from 2014 to study completion), and postoperative voice evaluation (n = 12). Postoperative inpatient days, complications, and postoperative endoscopic intervention were collected. To validate the aerodynamic benefit of EPCR, CFD modeling was carried out on one patient.ResultsThirteen patients (nine females, nine with intubation injury, and four with post–airway reconstruction dysphonia) underwent EPCR at a mean age of 11.0 years. The mean preoperative and postoperative Pediatric Voice handicap Index scores were 53.8 and 33.8, respectively (P = .006). Mean maximum phonation time preoperatively and postoperatively was 5.3 and 6.7, respectively (P = .04). Of eight patients who underwent preoperative CT imaging, all demonstrated a posterior gap. Modeling demonstrated a change in flow and pressure. The mean hospital stay was 2.4 days. Nine patients underwent postoperative endoscopic intervention, and one experienced a complication that resolved with intervention.ConclusionsPatients who underwent EPCR for dysphonia following intubation or airway reconstruction showed improvements in vocal efficiency, loudness, and perceived voice handicapping. Their hospital stay was brief, with few complications. CFD modeling corroborated these clinical findings. EPCR thus warrants consideration in the management of patients with posterior glottic diastasis.Level of Evidence4 Laryngoscope, 129:S1–S9, 2019
Design and Implementation of an Interactive Website for Pediatric Voice Therapy—The Concept of In-Between Care: A Telehealth Model
Purpose: This article describes the design and implementation of a web-based portal developed to provide supported home practice between weekly voice therapy sessions delivered through telehealth to children with voice disorders. This in-between care consisted of supported home practice that was remotely monitored by speech-language pathologists (SLPs). Methods: A web-based voice therapy portal (VTP) was developed as a platform so participants could complete voice therapy home practice by an interdisciplinary team of SLPs (specialized in pediatric voice therapy), telehealth specialists, biomedical informaticians, and interface designers. The VTP was subsequently field tested in a group of children with voice disorders, participating in a larger telehealth study. Results: Building the VTP for supported home practice for pediatric voice therapy was challenging, but successful. Key interactive features of the final site included 11 vocal hygiene questions, traditional voice therapy exercises grouped into levels, audio/visual voice therapy demonstrations, a store-and-retrieval system for voice samples, message/chat function, written guidelines for weekly therapy exercises, and questionnaires for parents to complete after each therapy session. Ten participants (9–14 years of age) diagnosed with a voice disorder were enrolled for eight weekly telehealth voice therapy sessions with follow-up in-between care provided using the VTP. Conclusion: The development and implementation of the VTP as a novel platform for the delivery of voice therapy home practice sessions were effective. We found that a versatile individual, who can work with all project staff (speak the language of both SLPs and information technologists), is essential to the development process. Once the website was established, participants and SLPs effectively utilized the web-based VTP. They found it feasible and useful for needed in-between care and reinforcement of therapeutic exercises.
Revision thoracic slide tracheoplasty: Outcomes following unsuccessful tracheal reconstruction
Objectives/HypothesisOver the past decade, thoracic slide tracheoplasty (TST) has become the principal operation in the management of congenital tracheal stenosis. The purpose of this report was to describe our experience with revision TST following unsuccessful prior tracheal reconstruction.Study DesignRetrospective analysis at an academic children's hospital.MethodsPatients undergoing TST on cardiopulmonary bypass between January 2005 and May 2014 were reviewed. Patients with a history of prior airway surgery were extracted for further analysis. Preoperative patient variables and postoperative outcomes were evaluated and compared between patients undergoing revision slide tracheoplasty (RTST) and a control group of 26 matched patients undergoing primary surgery TST.ResultsTwenty‐six revision patients (25 referrals, one primary patient) of 162 patients reviewed over the study period met inclusion criteria. Twenty‐three patients had a history of complete tracheal rings, and three patients had cartilaginous deficiency. A total of 41 airway reconstruction procedures had been performed prior to RTST. When compared to primary TST, patients undergoing RTST required fewer cardiac procedures intraoperatively, and fewer mean ventilator hours (P = .01) postoperatively. There was no significant difference in the median length of stay, requirement of >48 hours ventilation, or postoperative complications between groups. There was one nonsurgical postoperative mortality following RTST.ConclusionsDespite some differences in the postoperative management when compared to nonrevision cases, revision TST can be successfully performed after prior tracheal reconstruction with good postoperative outcomes.Level of Evidence4.
