RESUMO
PURPOSE: Cricopharyngeus muscle dysfunction (CPMD) is a common clinical occurrence with very few clear diagnostic criteria and multiple pathways for treatment. Incidence of CPMD is not known, but some data suggest around 25% of people with dysphagia experience some degree of CPMD, which negatively impacts swallowing safety and efficiency. Workup and treatment of CPMD can require multidisciplinary collaboration across laryngologists, speech-language pathologists with training in dysphagia management, and gastroenterologists. The purpose of this paper is to review what is known about CPMD and identify areas of future research in CPMD diagnosis and treatment. METHODS: An overview of CPMD, relative treatments and disorders, and a discussion of future areas of research needed to improve clinical care of CPMD. RESULTS: Details regarding historical background, pathophysiology and treatment practiced for CPMD are included. CONCLUSION: In summary, CPMD is a poorly defined disease due to a lack of understanding of its pathophysiology and the lack of consensus diagnostic criteria. Well-designed, prospective clinical trials are necessary to develop a better understanding of clinical incidence of CPMD, impact of the disorder on oropharyngeal swallowing, and how to approach treatment of the disorder surgically or in conjunction with therapy directed by a specialized speech-language pathologist.
RESUMO
OBJECTIVES: Cricopharyngeus muscle dysfunction (CPMD) is a common cause for progressive dysphagia and can lead to dietary restriction, reduced nutrition, weight loss, and pneumonia. Controversy exists whether CPMD is best managed with primary surgical treatment of the cricopharyngeus muscle and who represents a good surgical candidate. METHODS: Retrospective review of patients diagnosed with CPMD who underwent surgical treatment were evaluated through prospectively collected pre- and postoperative Eating Assessment Tool-10 (EAT-10) and Functional Oral Intake Scale (FOIS). Videofluoroscopic swallowing studies (VFSS) were reviewed for presence or absence of a high-pressure barium stream through the upper esophageal sphincter, termed the jet phenomenon (JP). RESULTS: We identified 42 patients with CPMD who underwent surgical treatment and had serial Eating Assessment Tool (EAT-10) measures obtained pre- and postoperatively. Mean EAT-10 scores improved by 12.1 points (95%CI = 8.6-15.6), p < 0.0001. There was a significantly greater improvement among patients with JP (|∆EAT-10|= 17.0, 95%CI = 12.5-21.4) compared to those without (|∆EAT-10|= 6.2, 95%CI = 1.6-10.8), p = 0.0013. Patients with JP also showed improved FOIS score (p = 0.0023) while those without JP did not. CONCLUSION: This study provides the initial report on the utility of JP as a VFSS feature that is strongly associated with improved outcomes following surgical treatment of CPMD. Further work determining the physiologic correlates responsible for JP will help clarify its predictive capabilities. LEVEL OF EVIDENCE: Level 3.

In Parkinson's disease (PD), oropharyngeal dysphagia is common and clinically relevant. The neurophysiology of dysphagia in PD is complex and incompletely understood. The aim of the study was to determine the changes in oropharyngeal deglutitive pressure dynamics in PD and to correlate these with clinical characteristics including dysphagia and PD severity. In prospective consecutive series of 64 patients with PD [mean age: 66.9 ± 8.3 (SD)], we evaluated dysphagia severity clinically as well as with Sydney Swallow Questionnaire (SSQ) and Swallow Quality-of-Life Questionnaire (SWAL-QOL). PD severity was assessed with Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS). We used high-resolution pharyngeal impedance manometry (HRPIM) to objectively evaluate swallow function and compared data from 23 age-matched healthy controls [mean age 62.3 ± 9.1 (SD)]. Metrics assessed were upper esophageal sphincter (UES), integrated relaxation pressure (IRP), relaxation time (RT), maximum opening (MaxAdm), and pharyngeal intrabolus pressure (IBP) and pharyngeal contractility (PhCI). Mean MDS-UPDRS score was positively associated with dysphagia severity on SSQ and SWAL-QOL. HRPIM in PD compared with controls showed impaired UES relaxation parameters, with shorter RT, and elevated IRP and IBP. MaxAdm was not affected. The overall pharyngeal contractility was significantly higher in PD. Only the IBP and IRP were associated with PD severity and only IBP was significantly associated with dysphagia severity. UES dysfunction leading to increased flow resistance is common in patients with PD and correlates with dysphagia severity. Increased flow resistance may suggest impaired UES relaxation and/or impaired neuromodulation to bolus volume.NEW & NOTEWORTHY In Parkinson's disease, objective assessment of swallow function with high-resolution impedance manometry identifies upper esophageal sphincter dysfunction leading to increased flow resistance.

This study aimed to investigate the efficacy and safety of a novel balloon catheter in dilation intervention for patients with cricopharyngeus achalasia after stroke. Thirty-four patients with cricopharyngeus achalasia after stroke received routine swallowing rehabilitation training and were randomly assigned to an experimental group (Exp, n = 17) that received dilation therapy using the novel balloon catheter once daily for 5 days per week or a control group (Con, n = 17) that received dilation therapy with a 14-Fr ordinary urinary catheter once daily for 5 days per week. The intervention duration, Eating Assessment Tool (EAT)-10 scores, and Functional Oral Intake Scale (FOIS) scores were recorded at baseline and each day during intervention. The time for a patient's FOIS score to be ≥ 3 as well as the recovery time for oral intake of water, liquid food, mushy food, and solid food were recorded or estimated. Complications were also recorded during intervention. The intervention duration was shorter in the Exp group than in the Con group (p = 0.005). The Exp group patients improved faster than the Con group patients, with a shorter recovery time for oral intake of liquid food (p = 0.002), mushy food (p = 0.001), and solid food (p = 0.001). At the time of intervention termination, EAT-10 scores were lower in the Exp group than in the Con group (p = 0.005). The Exp group had a similar incidence of complications as the Con group but with better tolerability (p = 0.028). Compared with the urinary catheter, the novel balloon catheter for dilation in patients with cricopharyngeus achalasia after stroke may lead to a better and more rapid recovery.

Cricopharyngeus muscle dysfunction (CPMD) is a common cause for progressive dysphagia and can lead to dietary restriction, reduced nutrition, weight loss, and pneumonia. There is a continuum between small, non-obstructive cricopharyngeus bars representing mild disease and severely obstructive bars or Zenker's diverticulum forming late-stage disease, but the natural history of untreated CPMD and the associated time course for progression is unknown. Retrospective longitudinal cohort study from a tertiary outpatient dysphagia centre. Patients diagnosed with CPMD by fluoroscopy and either awaiting surgical treatment or electing non-operative management were evaluated through prospectively collected Eating Assessment Tool-10 (EAT-10) and Functional Oral Intake Scale (FOIS). Review of available imaging identified degree of CPMD. We identified 174 patients with CPMD diagnosed between July 1, 2016, and June 30, 2020; 52 patients had serial Eating Assessment Tool (EAT-10) measures obtained at time of diagnosis and follow up appointment without operative treatment. Mean EAT-10 scores increased from 17.1 to 20.6 (3.5 ± 8.1 points, p = 0.002) points. This change was related to those with a Zenker's diverticulum rather than an isolated cricopharyngeus bar. Dietary outcomes measured by FOIS were stable. While some patients showed fluoroscopic progression of bar size, no patients developed a Zenker's diverticulum from a pre-existing bar in this population. Our data indicate patients with a cricopharyngeus bar do not decline in subjective dysphagia score or diet tolerance, however those with a Zenker's diverticulum worsen over time. This has implications for treatment timing and counselling patients but also reflects a need to understand the pathophysiology behind CPMD and the subset of patients who show progression.

BACKGROUND: Head and neck surgeries can perturb normal structures of neck muscles and nerve innervations, which are supposed to function in harmony to allow complicated process like swallowing. It is still likely that cricopharyngal dysfunction emerges years after the head and neck surgeries. CASE PRESENTATION: We report a case with history of left unilateral vocal cord immobility and development of dysphagia and aspiration 2 years after radical thyroidectomy with neck lymph nodes dissection and medialization thyroplasty. Cricopharyngeal dysfunction was impressed and was confirmed with visualization of cricopharyngeal narrowing segment in radiographic contrast swallow examination. The patient was treated successfully by cricopharyngeal myotomy, achieving long-term relief in our 4 years of follow up. CONCLUSIONS: Our case of delayed cricopharyngal dysfunction after radical thyroidectomy and medialization thyroplasty shows that it is important to follow up swallowing functions after patients with UVCI undergo medialization thyroplasty. In the event of delayed manifestation of cricopharyngeal function, it can still be treated successfully by cricoharyngeal myotomy, achieving long term relief of dysphagia.

Histological examination of specimens from 22 donated elderly cadavers and 15 human fetuses revealed that the cricopharyngeus muscle (CPM) provided (1) posterior circular muscle fibers adjacent to the external aspect of the uppermost esophageal circular muscle and (2) a thin anterior sling connecting to that same muscle. Another thick lateral bundle of longitudinal muscle originated independently from a fascia covering the posterior cricoarytenoideus muscle, extended laterally and posteriorly, and occupied a space after the CPM had disappeared at the anterolateral angle of the esophagus below the cricoid. The thick fascia contained abundant elastic fibers along the internal surface of the pharyngeal constrictors (posteromedial elastic lamina), but was interrupted or discontinued near the cricoid origin of the CPM. As no submucosal smooth muscles or elastic fibers were connected to it, the CPM did not accompany a specific elastic structure at the interface between the pharyngeal and esophageal muscles. In fetuses, the medial half of the CPM was inserted into the cricoid while the lateral half continued to the sternothyroideus muscle or ended at a fascia covering the cricothyroideus. These anterolateral ends provided a mechanical load for longitudinal growth of the pharyngeal constrictors. Consequently, the CPM was unlikely to develop and grow to form the upper esophageal sphincter, and the muscle bundle crossing the lateral aspect of the pharyngo-esophageal junction appeared to have a secondary passive role as a sphincter. This situation contrasts with that of another sphincter in the human body formed from striated muscle. Clin. Anat., 33:782-794, 2020. © 2019 Wiley Periodicals, Inc.

Although the precise etiology of cricopharyngeus muscle (CPM) dysfunction (CPMD) is uncertain, many have hypothesized that a hypertrophied CPM may develop as a protective compensation against gastroesophageal reflux disease (GERD). The purpose of this investigation was to evaluate the association between CPMD and the presence of hiatal hernia (HH) in an attempt to elucidate the potential etiology of CPMD. The charts of individuals who underwent video fluoroscopic esophagrams between 01/01/14 and 10/30/16 were reviewed from an electronic database. A group of 50 subjects with reported HH were identified and age- and gender-matched to an individual without HH. The prevalence of CPMD was compared between groups. The mean (± SD) age of the HH cohort was 64 (± 13.4) years and 64 (± 12.8) years for the group without HH (p > 0.05). Thirty-eight percent was male. The frequency of CPMD in the HH group was 78% versus 58% in the non-HH group (p < 0.05). Individuals with a HH were 2.57 times more likely to have evidence of CPMD (95% CI 1.07- 6.15). Although these data suggest an association between GERD and CPMD, further research is required before a causal relationship can be presumed.

The swallowing muscles that influence upper esophageal sphincter (UES) opening are centrally controlled and modulated by sensory information. Activation and deactivation of neural inputs to these muscles, including the intrinsic cricopharyngeus (CP) and extrinsic submental (SM) muscles, results in their mechanical activation or deactivation, which changes the diameter of the lumen, alters the intraluminal pressure, and ultimately reduces or promotes flow of content. By measuring the changes in diameter, using intraluminal impedance, and the concurrent changes in intraluminal pressure, it is possible to determine when the muscles are passively or actively relaxing or contracting. From these "mechanical states" of the muscle, the neural inputs driving the specific motor behaviors of the UES can be inferred. In this study we compared predictions of UES mechanical states directly with the activity measured by electromyography (EMG). In eight subjects, pharyngeal pressure and impedance were recorded in parallel with CP- and SM-EMG activity. UES pressure and impedance swallow profiles correlated with the CP-EMG and SM-EMG recordings, respectively. Eight UES muscle states were determined by using the gradient of pressure and impedance with respect to time. Guided by the level and gradient change of EMG activity, mechanical states successfully predicted the activity of the CP muscle and SM muscle independently. Mechanical state predictions revealed patterns consistent with the known neural inputs activating the different muscles during swallowing. Derivation of "activation state" maps may allow better physiological and pathophysiological interpretations of UES function.

The upper esophageal sphincter constitutes an important anatomic and functional landmark in the physiology of pharyngeal swallowing. A variety of clinical circumstances may call for a dedicated evaluation of this mechanism, from the etiologic evaluation of indeterminate symptoms to the generation of complex locoregional therapeutic strategies. Multiple diagnostic tools exist for the assessment of pharyngeal swallowing generally and of upper esophageal sphincter function specifically, some well established and others not yet settled into routine practice. This report reviews five specific modalities for use in making this assessment, outlining the strengths, weaknesses, and logistical considerations of each with respect to its potential use in clinical settings. In many cases, these studies will provide complementary information regarding pharyngeal function, suggesting the relative advantage of a multimodal evaluation.

OBJECTIVES: We sought to determine whether the association between cricopharyngeus muscle activity and upper esophageal sphincter pressure may change in a task-dependent fashion. We hypothesized that more automated tasks related to swallow or airway protection would yield a stronger association than would more volitional tasks related to tidal breathing or voice production. METHODS: Six healthy adult subjects underwent simultaneous intramuscular electromyography of the cricopharyngeus muscle and high-resolution manometry of the upper esophageal sphincter. Correlation coefficients were calculated to characterize the association between the time-linked series. RESULTS: Cricopharyngeus muscle activity was most strongly associated with upper esophageal sphincter pressure during swallow and effortful exhalation tasks (r = 0.77 and 0.79, respectively; P < .01). The association was also less variable during swallow and effortful exhalation. CONCLUSIONS: These findings suggest a greater coupling for the more automatic tasks, and may suggest less coupling and more flexibility for the more volitional, voice-related tasks. These findings support the important role of central patterning for respiratory- and swallow-related tasks.

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.

OBJECTIVE: To identify characteristics of patients who have poor improvement in symptoms following surgical management of Zenker Diverticulum (ZD). METHODS: Prospective, 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). RESULTS: A 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. CONCLUSION: Coexistent 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.

RESUMO
BACKGROUND: Retrograde cricopharyngeus dysfunction (R-CPD), a condition first detailed in 1987 and termed in 2019, refers to the cricopharyngeal muscle's inability to relax to allow the retrograde passage of gas. Limited research exists on the fundamental characteristics of this condition, including its impact on one's life. The purpose of this study is to characterize R-CPD and how the inability to burp affects the social lives of people who suffer from it. METHODS: A Qualtrics survey was distributed on the subreddit "r/noburp," a community of 26,000 individuals sharing information about R-CPD. Adults aged 18-89 experiencing R-CPD symptoms were invited to participate. Participants reported on their experiences with R-CPD and its effects on social life on a 4-point Likert scale (1 = strongly disagree to 4 = strongly agree). Data was analyzed using descriptive statistics. KEY RESULTS: Among the 199 respondents, the mean age was 30.9, and gender identity was 74%/25% female/male. 99% reported inability to burp, 98% reported abdominal bloating, 93% reported socially awkward gurgling noises, 89% reported excessive flatulence, and 55% reported difficulty vomiting. Only half discussed their symptoms with their primary care provider (PCP), and 90% disagreed with receiving adequate help. Average Likert scores indicated embarrassment (3.4), anxiety/depression (3.1), negative impact on relationships (2.6), and work disruption (2.7) due to R-CPD. CONCLUSIONS & INFERENCES: R-CPD is unfamiliar to many healthcare providers, leaving patients underserved. It not only affects daily life but also personal and professional relationships. Raising awareness by understanding disease basic features may increase diagnosis and treatment rates, improving quality of life.

OBJECTIVE: To compare improvement in patient-reported outcomes (PROM) in persons undergoing endoscopic and open surgical management of Zenker diverticula (ZD). METHODOLOGY: Prospective, 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. RESULTS: One 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. CONCLUSION: Both 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 EVIDENCE: 3 Laryngoscope, 134:97-102, 2024.

OBJECTIVES: To describe our center's experience with the identification and treatment of retrograde cricopharyngeus dysfunction (R-CPD), a syndrome involving the inability to belch previously described by only one institution. Additionally, because all patients initially learned of their condition and sought treatment as a result of social media posts, we queried their source and comfort with this form of medical referral. METHODS: Retrospective chart review of patients who underwent botulism toxin injection into the cricopharyngeus muscle for treatment of R-CPD from 2019 to 2022. Demographic data, most common symptoms at presentation, and response to treatment and complications were documented. Post-treatment questionnaires were reviewed. RESULTS: A total of 85 patients were identified. Mean age at surgery was 27 years. There were 54 (63.5%) females and 31 (36.5%) males. The inability to burp (98.8%), bloating (92.9%), gurgling noises (31.8%), and excessive flatulence (21.2%) were the most common symptoms. The minimum units of botox utilized were 25, whereas the maximum was 100. The majority of patients (88.2%) had a successful response at initial follow-up visit. The most common complication was mild dysphagia (30.6%), which was transient for all patients. Most patients learned of our practice through social media, with only one patient being referred by a medical provider. CONCLUSIONS: The majority of patients in our cohort were young and female. The inability to burp and bloating were the most common presenting symptoms. Social media was the primary source of referral. Our institution favors 80-100 units for an effective response.

OBJECTIVE: To assess barium esophagram (BAS) as a diagnostic marker for patients with Killian Jamieson diverticula (KJD). METHODS: Prospective, 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. RESULTS: A 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). CONCLUSION: KJD 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 EVIDENCE: 4 Laryngoscope, 133:2110-2115, 2023.

Dysphagia is a watershed symptom that localises poorly. Dividing causes of dysphagia into oropharyngeal and oesophageal does not always best serve the patient. We report the case of a patient whose diagnosis and treatment required three separate specialist referrals to two specialties, with 18 months passing between initial referral and definitive treatment. The predominant pathology was isolated upper oesophageal sphincter dysfunction that responded well to laser cricopharyngeal myotomy. Following surgery, patient symptoms resolved and lost weight was regained. High-resolution manometry showed that the upper sphincter resting pressure had fallen from 117±45 to 21±11mmHg, but the lower sphincter resting pressure had risen, albeit without symptoms, from 16±8 to 44±17mmHg (p<0.001 in both cases). Surgery on upper oesophageal sphincter in the presence of lower oesophageal sphincter incompetence is known to lead to intractable regurgitation and pneumonia, and this novel physiological observation further emphasises the need to holistically consider the patient and to systematically evaluate the entire swallowing system before undertaking invasive interventions.
RESUMO
A large constellation of hitherto unexplained symptoms including inability to burp, gurgling noises from the chest and lower neck, abdominal bloating, flatulence, painful hiccups and emetophobia was defined as Retrograde Cricopharyngeus Dysfunction (R-CPD) in 2019. First choice treatment of R-CPD involves injection of botulinum toxin into the cricopharyngeus muscle under local or general anesthesia. This treatment has been found to be effective in the vast majority of subjects, with limited adverse events and prolonged therapeutic effects. Notwithstanding, R-CPD is still a poorly understood and underestimated disease, and a specific therapeutic dosage range of botulinum toxin (BT) has not been yet established. In this report, we describe the first case of R-CPD diagnosed in Italy, successfully treated with unilateral, anesthesia-free injection of 10 units of onabotulinum toxin into the cricopharyngeus muscle, representing the lowest dose reported to date.
RESUMO
OBJECTIVE: To 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. METHODOLOGY: Prospective, 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. RESULTS: A 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). CONCLUSION: ZD 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 EVIDENCE: 4 Laryngoscope, 133:1349-1355, 2023.
