Cricopharyngeal Myotomy
Cricopharyngeal myotomy is a surgical sectioning of the cricopharyngeus muscle, also known as the upper esophageal sphincter, that has been advocated for the treatment of cricopharyngeal spasm, or cricopharyngeal achalasia, that leads to cervical dysphagia in the clinical setting. This surgery can be used for retrograde cricopharyngeal dysfunction Retrograde cricopharyngeus dysfunction (R-CPD; also known as the inability to belch syndrome) is a medical condition first identified by gastroenterologist, Dr Peter Kahrilas, in 1987.

Cricopharyngeus Muscle
The inferior pharyngeal constrictor muscle is a skeletal muscle of the neck. It is the thickest of the three outer pharyngeal muscles. It arises from the sides of the cricoid cartilage and the thyroid cartilage. It is supplied by the vagus nerve (CN X). It is active during swallowing, and partially during breathing and speech. It may be affected by Zenker's diverticulum. Structure The inferior pharyngeal constrictor muscle is composed of two parts. The first part (and more superior) arises from the thyroid cartilage (thyropharyngeal part), and the second part arises from the cricoid cartilage (cricopharyngeal part). * On the ''thyroid cartilage'', it arises from the oblique line on the side of the lamina, from the surface behind this nearly as far as the posterior border and from the inferior horn of the thyroid cartilage. * From the ''cricoid cartilage'', it arises in the interval between the cricothyroid muscle in front, and the articular facet for the inferior horn of th ...

Upper Esophageal Sphincter
The esophagus (American English), oesophagus (British English), or œsophagus ( archaic spelling) ( see spelling difference) all ; : ((o)e)(œ)sophagi or ((o)e)(œ)sophaguses), colloquially known also as the food pipe, food tube, or gullet, is an organ in vertebrates through which food passes, aided by peristaltic contractions, from the pharynx to the stomach. The esophagus is a fibromuscular tube, about long in adults, that travels behind the trachea and heart, passes through the diaphragm, and empties into the uppermost region of the stomach. During swallowing, the epiglottis tilts backwards to prevent food from going down the larynx and lungs. The word ''esophagus'' is from Ancient Greek οἰσοφάγος (oisophágos), from οἴσω (oísō), future form of φέρω (phérō, "I carry") + ἔφαγον (éphagon, "I ate"). The wall of the esophagus from the lumen outwards consists of mucosa, submucosa (connective tissue), layers of muscle fibers between layers of ...

Cricopharyngeal Spasm
Cricopharyngeal spasms occur in the cricopharyngeus muscle of the pharynx. Cricopharyngeal spasm is an uncomfortable but harmless and self-limiting (biology), temporary disorder. Signs and symptoms * Sensation of a 'lump' in the back of the throat * Throat feels swollen * Discomfort - Lump can often feel quite big and pain is occasional * Symptoms normally worse in the evening * Stress (biology), Stress aggravates the symptoms * Saliva is difficult to swallow, yet food is easy to swallow - eating, in fact, often makes the tightness go away for a time * 'Lump' sensation comes and goes from day to day * Symptoms can persist for very long periods, often several months. * The symptoms can be mimicked by pushing on the cartilage in the neck, just below the Adam's apple Physiology There are two sphincters in the oesophagus. They are normally contracted and they relax when one swallows so that food can pass through them going to the stomach. They then squeeze closed again to prevent r ...

Retrograde Cricopharyngeal Dysfunction
Retrograde cricopharyngeus dysfunction (R-CPD; also known as the inability to belch syndrome) is a medical condition first identified by gastroenterologist, Dr Peter Kahrilas, in 1987. However, the condition only began to receive more attention following a 2019 report by ENT surgeon, Dr Robert Bastian, which described a very high rate of symptomatic relief from injection of botulinum toxin into the cricopharyngeus muscle. Uniquely, awareness of the condition has spread predominantly through patients themselves rather than the medical community via numerous social media forums. Awareness of the condition amongst primary care physicians and specialists remains low and patients report needing to seek out specialists who are familiar with and can treat the condition through online research. Symptoms The condition is characterised by chronic gastrointestinal symptoms relating to excessive gas retention including abdominal bloating with distension, flatulence, audible gurgling sounds, ...
