Summary
This study investigated upper functional dysphagia in 33 patients without obstruction. Cricopharyngeal myotomy showed good results in 10 out of 16 patients, highlighting its potential for treating swallowing disorders.
Area of Science:
- Gastroenterology
- Neurology
- Otolaryngology
Context:
- Upper functional dysphagia involves complex swallowing reflex and timing disturbances.
- Examines 33 patients with dysphagia unrelated to tumoral obstruction.
- Investigates neurological, myopathic, and upper esophageal sphincter causes.
Purpose:
- To explore the causes and diagnostic methods for upper functional dysphagia.
- To evaluate the efficacy of cricopharyngeal myotomy in treating this condition.
Summary:
- Thirty-three patients with upper functional dysphagia were studied using fiberendoscopy, manometry, and MRI.
- Causes included neurological conditions (brainstem tumors, cerebrovascular disease), myopathy, and upper esophageal sphincter issues.
- Cricopharyngeal myotomy was performed on 16 patients, with 10 experiencing positive outcomes.
Impact:
- Provides insights into the diagnostic approach for non-obstructive upper dysphagia.
- Evaluates cricopharyngeal myotomy as a therapeutic option for specific dysphagia cases.
- Contributes to understanding the management of swallowing disorders affecting the velopharyngoesophageal segment.
