What is hypopharyngeal diverticulum?
Zenker’s diverticulum (ZD), also known as cricopharyngeal, pharyngoesophageal or hypopharyngeal diverticulum, is a rare condition characterized by an acquired outpouching of the mucosal and submucosal layers originating from the pharyngoesophageal junction.
What causes pharyngeal diverticulum?
Causes of Pharyngeal Pouch / Zenker’s Diverticulum It’s believed the primary cause of Zenker diverticulum is tightness or malfunctioning of your cricopharyngeal muscle as you age.
What causes UES dysfunction?
Impaired opening of the UES can result from cricopharyngeal fibrosis, disordered neurally-mediated opening, suboptimal pharyngeal driving force, or a combination of these factors.
What are the symptoms of Zenker diverticulum?
Zenker’s Diverticulum
- Difficulty swallowing (dysphagia)
- Undigested food that comes back up.
- Cough, especially at night.
- Hoarseness.
- Pneumonia.
- Bronchitis.
- Food getting into the breathing passages or lungs (aspiration)
What are the symptoms of a pharyngeal pouch?
A pharyngeal pouch, also known as Zenker’s diverticulum, occurs when part of the pharyngeal lining herniates through the muscles of the pharyngeal wall. This occurs mainly in older people. Presenting symptoms include dysphagia, regurgitation of undigested food, halitosis, hoarseness, and chronic cough.
How do you fix UES?
The definitive treatment for cricopharyngeal dysfunction is a procedure called cricopharyngeus muscle myotomy in which physicians cut the UES in a way that prevents it from over-contracting, so food is no longer blocked from entering the esophagus.
How do you strengthen your UES?
By lifting and holding the neck from a supine position for 60 seconds at a time, you create enough tension in the muscle associated with the upper esophageal sphincter that it can strengthen the valve.
What is Passavant’s Ridge?
A. Flexible fiberscopic transnasal view of the nasopharynx showing the roof of the soft palate at the bottom of the view. The bulge of posterior pharyngeal wall that meets the soft palate is called Passavant’s ridge.
Why killians dehiscence is called Gateway of tears?
Killian’s dehiscence is a gap between oblique and transverse fibers of inferior constrictor. Significance: A pharyngeal pouch (or Zenkers diverticulum) can be formed by outpouching of pharyngeal mucosa at this site. It is a common site for perforation during esophagoscopy hence called as Gateway of Tears.
