What is CP bar?
The cricopharyngeal (CP) bar can form from a thickening of the cricopharyngeus muscle caused by replacement of its muscle with fibrous connective. This is thought by many to be a reaction to chronic reflux of stomach contents into the esophagus.
How common is cricopharyngeal bar?
CP bar is seen in 4-15% of patients undergoing pharyngeal radiography. It is seen as a prominent extrinsic defect on the posterior aspect of the cervical esophagus and is best seen on lateral projections radiographically.
What does prominent cricopharyngeal mean?
Cricopharyngeal bar refers to the radiographic appearance of a prominent cricopharyngeus muscle contour on barium swallow.
What is the function of the upper esophageal sphincter?
The main functions of UES closure are to prevent esophageal air insufflation during negative intrathoracic pressure events, for example, inspiration, and to prevent esophagopharyngeal/laryngeal reflux during esophageal peristalsis.
What is painful swallowing called?
“Odynophagia” is the medical term for painful swallowing. Pain can be felt in your mouth, throat, or esophagus. You may experience painful swallowing when drinking or eating food. Sometimes swallowing difficulties, known as dysphagia, can accompany the pain, but odynophagia is often a condition of its own.
What is a Zenker’s diverticulum?
A Zenker’s diverticulum is an outpouching that occurs at the junction of the lower part of the throat and the upper portion of the esophagus. The pouch forms because the muscle that divides the throat from the esophagus, the cricopharyngeal (CP) muscle, fails to relax during swallowing.
What causes the upper esophageal sphincter to relax?
Key Points. At rest, closure of the upper esophageal sphincter (UES) is due to passive forces as well as active muscle contraction, and its relaxation requires inhibition of the cricopharyngeus and contraction of suprahyoid muscles.
What is the Mendelsohn maneuver?
The Mendelsohn maneuver is a method of intentionally holding the larynx when the larynx is elevated, so that activation of the suprahyoid muscles is induced4). In this study, the Mendelsohn maneuver was performed for approximately 5 seconds, and the suprahyoid muscles would have been activated within this time.
How do you fix the upper esophageal sphincter?
Treatments for upper esophageal sphincter dysfunction include botulinum toxin injection into cricopharyngeal muscle, UES dilation, endoscopic cricopharyngeal myotomy or transcervical cricopharyngeal myotomy.
Does Cricopharyngeal go away?
According to Laryngopedia, the symptoms of cricopharyngeal spasm tend to resolve on their own after around three weeks. In some cases, symptoms can last longer. You may need to see your doctor to rule out other possible causes of throat spasm to make sure you don’t have a more serious condition.
How is Cricopharyngeal muscle treated?
Options of home treatments for cricopharyngeal spasms include:
- relaxation techniques, including controlled breathing, meditation, guided thought, and visualization.
- over-the-counter muscle relaxants.
- heated bags or pads, as well as warm drinks or foods.
- eating and drinking foods, slowly, to prolong the absence of symptoms.
What is Killian dehiscence?
The Killian dehiscence is a triangular-shaped area of weakness in the muscular wall of the pharynx, between the transverse and oblique bundles of the inferior pharyngeal constrictor 1. It is the most common site of pharyngeal diverticula 5.
What are the functions of the upper and lower esophageal sphincters?
The upper esophageal sphincter opens (2) so that food can enter the esophagus, where waves of muscular contractions, called peristalsis, propel the food downward (3). The food then passes through the diaphragm (4) and lower esophageal sphincter (5) and moves into the stomach.
How many sphincters are in the Oesophagus?
There are two sphincters present in the oesophagus, known as the upper and lower oesophageal sphincters. They act to prevent the entry of air and the reflux of gastric contents respectively. The upper sphincter is an anatomical, striated muscle sphincter at the junction between the pharynx and oesophagus.
What are the two sphincters of the esophagus?
The antireflux barriers include two sphincters, namely, the lower esophageal sphincter (LES) and the diaphragmatic sphincter, and the unique anatomic configuration at the gastroesophageal junction.
