Traditional septotomy or Z-POEM for Zenker's diverticulum.

Zenker's diverticulum (ZD), also known as a cricopharyngeal pouch, is a pulsion pseudodiverticulum located dorsally at the pharyngoesophageal junction. The pathophysiology of ZD involves cricopharyngeal spasm, incoordination, impaired upper esophageal sphincter opening, and structural changes in the cricopharyngeal muscle, leading to symptoms such as dysphagia, regurgitation of undigested food, foreign body sensation, halitosis, unintentional weight loss, and respiratory issues. Treatment for symptomatic ZD typically involves myotomy of the cricopharyngeal muscle. Endoscopic techniques, particularly flexible endoscopy septotomy (FES) and Zenker peroral endoscopic myotomy (Z-POEM), have become preferred options due to their minimally invasive nature. This review discusses the techniques and clinical outcomes of FES and Z-POEM, focusing on specific clinical scenarios to guide the choice between these methods. Additionally, the variability in FES techniques, the effectiveness of Z-POEM, and the impact of different diverticulum sizes on treatment outcomes are analyzed, providing a comprehensive overview of current therapeutic approaches for ZD.

The palatopharyngeal muscle in otolaryngology practice: an anatomical-based surgical report.

OBJECTIVES: The author discusses current otolaryngological procedures employing the palatopharyngeus muscle, based on the surgical anatomy of the muscle and its neural supply. These techniques should be deeply revised for more conservative, anatomically-based maneuvers. METHODS: Revision of anatomical and surgical research and comments with the provision of a primary concept. RESULTS: The palatopharyngeus muscle is innervated by the pharyngeal plexus (the vagus and the accessory nerves) with additional fibers from the lesser palatine nerves. The innervation enters the muscle mainly through its lateral border. CONCLUSIONS: The palatopharyngeus muscle has a fundamental role in swallowing and speech. The muscle helps other dilators to maintain upper airway patency. Sphincter pharyngoplasty should be revised as regards its role as a sphincter. Palatopharyngeal procedures for OSA employing the palatopharyngeus muscle should follow the conservative, anatomically-based, and non-neural ablation concept.

[Clinical effect of the modified pharyngeal flap of bilateral muscular rings in the treatment of moderate and severe velopharyngeal insufficiency].

To introduce the modified pharyngeal flap of bilateral muscular rings (BMR), and to discuss the clinical effect of this operation in the correction of moderate and severe velopharyngeal insufficiency. The clinical data of 18 patients who underwent BMR surgery in the Department of Craniofacial Plastic and Aesthetic Surgery, School of Stomatology, The Fourth Military Medical University from May 2019 to July 2021 were retrospectively analyzed. There were 10 males and 8 females, with a median age of 8.5 years (aged from 5 to 34 years). The patients were diagnosed preoperatively with moderate to severe velopharyngeal insufficiency (velopharyngeal closure ratio<0.7). The results of nasopharyngoscopy and speech assessment were compared and analyzed before operation and at the follow-up 6 months after the operation to evaluate the changes in velopharyngeal function and speech. Eighteen patients underwent BMR, 4 patients had snoring (the symptom disappeared after a few weeks in 3 cases), and 2 patients had local erosion of the wound, which delayed healing. Postoperative nasopharyngoscopy showed that all patients achieved comparatively complete velopharyngeal closure, some patients got enhanced lateral pharyngeal wall motility, and all patients got active motility of posterior pharyngeal wall flap. The postoperative speech assessment was significantly improved compared with that before the operation. The preoperative median score was 9 (range 7-12), and the postoperative median score was 2 (range 0-4). The statistical analysis was performed by paired non-parametric Wilcoxon signed rank test, and the difference was statistically significant (P<0.001). BMR is a reliable method for the treatment of moderate and severe velopharyngeal insufficiency. This technique can achieve functional contraction of the full circumference of the ventilator while preserving the obstructive effect of the posterior pharyngeal wall flap, which is helpful to balance nasal ventilation and velopharyngeal closure and improve the velopharyngeal function of patients.

Magnetic Resonance Imaging of the Velopharynx: Clinical Findings in Patients with Velopharyngeal Insufficiency.

BACKGROUND: Magnetic resonance imaging (MRI) is the only imaging modality capable of directly visualizing the levator veli palatini (LVP) muscles: the primary muscles responsible for velopharyngeal closure during speech. MRI has been used to describe normal anatomy and physiology of the velopharynx in research studies, but there is limited experience with use of MRI in the clinical evaluation of patients with velopharyngeal insufficiency (VPI). METHODS: MRI was used to evaluate the velopharyngeal mechanism in patients presenting for VPI management. The MRI followed a fully awake, nonsedated protocol with phonation sequences. Quantitative and qualitative measures of the velopharynx were obtained and compared with age- and sex-matched individuals with normal speech resonance. RESULTS: MRI was completed successfully in 113 of 118 patients (96%). Compared with controls, patients with VPI after cleft palate repair had a shorter velum (P < 0.001), higher incidence of LVP discontinuity (P < 0.001), and shorter effective velar length (P < 0.001). Among patients with persistent VPI after pharyngeal flap placement, findings included a pharyngeal flap base located inferior to the palatal plane [11 of 15 (73%)], shorter velum (P < 0.001), and higher incidence of LVP discontinuity (P = 0.014). Patients presenting with noncleft VPI had a shorter (P = 0.004) and thinner velum (P < 0.001) and higher incidence of LVP discontinuity (P = 0.014). CONCLUSIONS: MRI provides direct evidence of LVP muscle anomalies and quantitative evaluation of both velar length and velopharyngeal gap. This information is unavailable with traditional VPI imaging tools, suggesting that MRI may be a useful tool for selecting surgical procedures to address patient-specific anatomic differences.

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. LEVEL OF EVIDENCE: Level III Laryngoscope, 134:2678-2683, 2024.

Combined laryngeal framework surgery and cricopharyngeal muscle-origin transection: a novel effective surgery for dysphagia with pharyngolaryngeal palsy and cricopharyngeal dysfunction under local anesthesia.

BACKGROUND: Cricopharyngeal myotomy and laryngeal framework surgery can improve swallowing function in patients with severe dysphagia. We developed a novel surgical technique for severe dysphagia associated with pharyngolaryngeal paralysis and cricopharyngeal dysfunction, performed under local anesthesia, and investigated its effectiveness. METHODS: We included nine patients who underwent cricopharyngeal muscle-origin transection with laryngeal framework surgery through a horizontal skin incision under local anesthesia. CONCLUSIONS: All patients demonstrated significant improvement in the Food Intake LEVEL Scale without complications. Thus, this surgical technique may serve as a useful and less invasive treatment option for patients with severe dysphagia.

Cricopharyngeal and thyropharyngeal myectomy for management of cricopharyngeal achalasia in a 6-month-old coton de Tulear dog.

A 6-week-old intact female coton de Tulear dog presented to a veterinary teaching hospital (VTH) internal medicine service for dysphagia that was persistent since birth. The patient was diagnosed with cricopharyngeal achalasia based on a fluoroscopic swallow study. To facilitate surgical intervention, a percutaneous endoscopic gastrostomy (PEG) tube was placed to bypass the upper esophageal sphincter and provide nutritional support until the dog was larger. At 6 mo of age, the dog underwent unilateral cricopharyngeal and thyropharyngeal myectomy. Marked improvement in dysphagia was noted immediately postoperatively. Improvement in dysphagia persisted in this dog, with continued marked improvement in clinical signs noted 1 y postoperatively. Key clinical message: Cricopharyngeal achalasia can be successfully managed with surgical intervention with a good long-term prognosis. Before surgical intervention, nutritional support is of critical importance. A combined procedure of cricopharyngeal and thyropharyngeal myectomy may be associated with outcomes superior to those of alternative procedures.

Myectomie cricopharyngée et thyropharyngée pour prise en charge de l'achalasie cricopharyngée chez un chien coton de Tuléar âgé de 6 mois. Une chienne coton de Tuléar femelle intacte âgée de 6 semaines a été présentée au service de médecine interne d'un CHU vétérinaire pour une dysphagie persistante depuis la naissance. Le patient a reçu un diagnostic d'achalasie cricopharyngée sur la base d'une étude fluoroscopique de la déglutition. Pour faciliter l'intervention chirurgicale, un tube de gastrostomie endoscopique percutanée (PEG) a été placé pour contourner le sphincter supérieur de l'oesophage et fournir un soutien nutritionnel jusqu'à ce que le chien soit plus gros. À l'âge de 6 mois, le chien a subi une myectomie cricopharyngée et thyropharyngée unilatérale. Une nette amélioration de la dysphagie a été notée immédiatement après l'opération. L'amélioration de la dysphagie a persisté chez ce chien, avec une amélioration continue et marquée des signes cliniques notée 1 an après l'opération.Message clinique clé :L'achalasie cricopharyngée peut être gérée avec succès par une intervention chirurgicale avec un bon pronostic à long terme. Avant l'intervention chirurgicale, le soutien nutritionnel est d'une importance cruciale. Une procédure combinée de myectomie cricopharyngée et thyropharyngée peut être associée à des résultats supérieurs à ceux des procédures alternatives.(Traduit par Dr Serge Messier).

Diagnosing and managing dysphagia in inclusion body myositis: a systematic review.

OBJECTIVES: Dysphagia is a common debilitating clinical feature of IBM. However, the impact of dysphagia in IBM has been historically overlooked. This study aimed to identify, evaluate and summarize the evidence regarding the assessment and management of dysphagia in persons with IBM undergoing treatment. METHODS: A systematic review was conducted using a multiengine search following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 guidelines. Eligible studies had to employ an intervention for persons with IBM, report a swallowing outcome and be published in English. Quality assessments of the eligible studies were performed. RESULTS: Of 239 studies found, 19 met the inclusion criteria. One study was rated as 'fair' and the rest as 'poor' quality, particularly due to the lack of published and validated swallowing assessment procedures and outcome measures. Cricopharyngeal (CP) dysfunction (12/19) was the most commonly reported swallowing abnormality. Interventions for disease management included pharmacological agents (10/19), followed by surgical (3/19), behavioral (1/19) and combined approaches (5/19). Interventions with immunosuppressants, botulinum toxin injection, balloon dilation and/or CP myotomy led to mixed and transient benefits. Few studies examining statins or behavioral therapies (primarily focused on respiratory function) showed no effects for dysphagia. CONCLUSION: Various interventions have been reported to temporarily improve dysphagia in persons with IBM. However, these findings are based on limited and overall low-quality evidence. This study cautions against the generalization of these findings and emphasizes the need for further systematic research to improve the diagnosis and management of dysphagia in IBM.
