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
Proximal Scar Progression in Idiopathic Subglottic Stenosis After Wedge Excision: Does it Happen?
ObjectiveTo compare the incidence of glottic stenosis in idiopathic subglottic stenosis (iSGS) patients with no prior surgical intervention to those with a history of endoscopic dilation and characterize the incidence of glottic involvement, changes in scar length, and progression of scar toward glottis following laser wedge excision (LWE).MethodsA retrospective review of iSGS patients who underwent LWE between 2002 and 2021 was performed. Patients without prior airway surgery were labeled LWE primary (LWEP) and operative findings for LWEP patients were reviewed for glottic involvement, scar length (DL), and distance from the glottis to superior‐most aspect of scar (DGS). Rates (in mm/procedure) of DΔL, reflecting an increase in length, and D−ΔGS, reflecting proximal migration, were calculated by dividing DΔL and D−ΔGS by the number of LWE procedures.Results213 iSGS patients underwent LWE, with 132 being LWEP patients. LWEP had a lower incidence of baseline glottic involvement (n = 6, 4.5%) than LWE secondary (LWES; n = 6, 7.5%). Four new cases of glottic involvement were noted in LWEP patients following LWE, with only one being clinically significant resulting in permanently decreased vocal fold mobility. With each procedure, scar length increased by 1.0 mm and DGS decreased by 0.7 mm, reflecting a migration or decrease in DGS of 9.5% with each procedure with respect to initial DGS. Overall rates of glottic stenosis following operations were similar between LWEP and LWES cohorts, 7.6% and 7.5% respectively.ConclusionThere appears to be a low risk of glottic involvement resulting from the LWE procedure in iSGS patients.Level of Evidence4 Laryngoscope, 133:875–882, 2023
Recurrence Following Endoscopic Laser Wedge Excision and Triple Medical Therapy for Idiopathic Subglottic Stenosis
ObjectiveWe present the outcomes for patients with idiopathic subglottic stenosis (iSGS) following their first carbon dioxide laser wedge excision (LWE) procedure, additionally examining the effect of compliance with adjuvant medical therapy (triple therapy) after the operation.Study DesignRetrospective chart review.SettingTertiary center.MethodsA retrospective review was performed on 183 patients with iSGS following their first LWE and their compliance to adjuvant medical therapy (inhaled corticosteroid, proton pump inhibitor, trimethoprim‐sulfamethoxazole) following the operation, with all reviewed to December 31, 2020. The primary outcome variable was median time to recurrence (MTR). Patients were stratified by whether the LWE was their first operation (LWE primary or secondary), by compliance to triple therapy, and by compliance with trimethoprim‐sulfamethoxazole. Kaplan‐Meier analysis and Cox proportional hazards were used to evaluate the MTR across the stratifications.ResultsAn overall 113 patients underwent their first LWE, while 70 received the procedure after having undergone 1 to 13 procedures. The MTR between LWE primary and secondary was 4.6 and 2.9 years, respectively. Adjusted Cox proportional hazards comparing these 2 groups revealed the number of prior operations to be a confounding variable. A statistically increased MTR was demonstrated with greater degrees of medical compliance.ConclusionLWE conferred an MTR of 4.1 years in the iSGS cohort. The number of prior procedures preceding LWE behaved as a confounding variable. Patients who were completely or partially compliant to triple therapy appear to demonstrate increased intervals prior to recurrence.
Predicting Gag, Discomfort, and Laryngeal Visualization in Patients Undergoing Flexible Laryngoscopy with Stroboscopy
Objective: To investigate potential associations between the Predictive Gagging Survey (PGS) with patient experience of gag and discomfort as well as provider perception of patient gag and level of laryngeal visualization during flexible laryngoscopy with stroboscopy (FL-S). Methods: A total of 53 adult patients undergoing FL-S were recruited for this prospective non-controlled study. PGS was completed before FL-S. Patients rated perceived level of gag and discomfort on a 10-point severity scale after FL-S. Additionally, providers completed a Gagging Severity Index (GSI) reflecting their impression of patient gag and level of laryngeal visualization following FL-S. Spearman rank correlation coefficients were used to assess associations. Results: There was a positive association with PGS score and patient perception of gagging (0.34; P = .013) and patient perception of discomfort (0.38; P = .005). No significant association was found between PGS score and provider GSI (−0.12; P = .39) or level of laryngeal visualization (0.15; P = .29). A negative association was found between level of laryngeal visualization and patient perception of gagging (−0.34; P = .012) and discomfort (−0.44; P = .001). No significant differences were found between current and former smokers compared to never smokers for GSI or patient-perceived gag or discomfort. Conclusions: While not predictive of GSI or level of laryngeal visualization, the PGS was found to be a useful tool in predicting patient experience of gagging and discomfort during FL-S, further reinforcing the subjective experience of this procedure. Use of the PGS may be helpful in identifying specific candidates who may struggle with subjective discomfort or gagging during FL-S for future studies considering interventions to manage and meaningfully decrease discomfort. Having such an instrument is important given the low number of individuals who struggle with discomfort during the exam.
In Response to Regarding Cricopharyngeal Myotomy in IBM: Comparison of Endoscopic and Transcervical Approaches
ObjectiveInclusion body myositis (IBM) is a progressive inflammatory myopathy with dysphagia as a debilitating sequalae. Otolaryngologists are consulted for surgical candidacy when there are findings of cricopharyngeal dysfunction. We aim to compare transcervical cricopharyngeal myotomy (TCPM) versus endoscopic cricopharyngeal myotomy (ECPM) in the IBM population with particular focus on objective swallow study outcomes, complications, and recurrence rates.MethodsA retrospective cohort study was performed on IBM patients who underwent TCPM or ECPM (1981–2020) in the Department of Otolaryngology at a tertiary academic center with a high volume IBM referral base. Videofluoroscopic swallow studies, Eating Assessment Tool (EAT‐10), Reflux Symptom Index (RSI), and Functional Outcome Swallowing Scale (FOSS) were collected at preoperative and follow‐up visits. Baseline patient characteristics, intraoperative data, and postoperative course were recorded.ResultsForty‐one patients were identified (18 TCPM; 23 ECPM). There was no significant difference in the recurrence rates, complications, hospitalization length, operative time, or return to preoperative diet between approaches. For the 12 patients (11 ECPM; 1 TCPM) that had subjective swallow data, there was a statistically significant difference in the pre and postoperative scores for EAT‐10, RSI, and FOSS (P < .05). There was a statistically significant improvement in the degree of narrowing between pre and postoperative imaging for both approaches (P < .05).ConclusionBoth TCPM and ECPM are safe approaches for the management of dysphagia in patients with IBM with objective evidence of cricopharyngeal dysfunction. Cricopharyngeal myotomy is a durable technique that has demonstrated improved subjective and objective outcomes in this patient population.Level of Evidence3 Laryngoscope, 131:E2426–E2431, 2021
Endoscopic Wedge Excisions with
CO2
Laser for Subglottic Stenosis
Objective: Recurrent laryngeal nerve injury is a potential complication of cardiothoracic surgery and cause of unilateral vocal fold paralysis (UVFP). Injection laryngoplasty (IL) is an intervention offered to patients with UVFP to alleviate symptoms including dysphagia, dysphonia and weak cough. There is no definitive evidence that IL prevents pneumonia. In this study, we compare rates of pneumonia in patients with UVFP secondary to cardiothoracic surgery who did or did not undergo IL. Methods: A retrospective chart review identified patients diagnosed with UVFP by an otolaryngologist using flexible laryngoscopy following cardiothoracic surgery from January 1, 2008 to December 31, 2017. Each subject was grouped by IL status and assessed for subsequent pneumonia within 6 months of their diagnosis of UVFP. The association of IL with pneumonia was evaluated using Cox proportional hazards regression. Results: Of 92 patients who met inclusion criteria, 35 (38%) underwent IL and 57 (62%) did not. Twenty patients developed pneumonia, four who had undergone IL and 16 who had not; 12 patients developed aspiration pneumonia including two having undergone IL and 10 who had not. Those who had IL were less likely to develop total pneumonia compared to those who had not (HR = 0.33, P = .045). The protective effect of IL was not as clearly sustained when measuring for aspiration pneumonia, specifically (HR = 0.34; P = .10). Discussion: Injection laryngoplasty may reduce the risk of pneumonia in patients with UVFP secondary to cardiothoracic surgery; however, further research is needed to quantify the potential protective nature of IL in this patient population. Level of evidence: 3 (A retrospective cohort study).
Acute airway compromise after recombinant human TSH administration: A case report and review of the literature
Radioiodine ablation is a commonly utilized treatment for differentiated thyroid carcinoma. Uptake of radioiodine can be enhanced by pretreatment with thyroid hormone withdrawal or administration of recombinant human thyroid‐stimulating hormone (rhTSH). rhTSH is generally well‐tolerated with minimal adverse effects. However, in patients with extensive tumor burden in confined anatomic spaces, rapid enlargement of normal or neoplastic thyroid tissue secondary to rhTSH administration can result in significant compressive effects. In this report, we describe a case of rapid airway deterioration requiring intubation in a patient with involvement of the thyroid cartilage by papillary thyroid carcinoma.Laryngoscope, 122:0000–0000, 2019 Laryngoscope, 130:2725–2727, 2020
