What is pyriform sinus?

pyriform sinus is a pear -shaped pear that line the sides of the larynx or voice cabinet. It is part of the structure in the body responsible for speech. Alternative terms include piriform sinus, piriform recesses and piriform fossa. Also known as Aryepiglottis, it represents the boundaries of the larynx. Pyriform sinus is lined with thyroid cartilage, the largest flexible connective tissue of the skeleton on the larynx; and the hyothyroid membrane that surrounds this cartilage. At the bottom of the pear -shaped pear there is a Cricoid cartilage, a circle -shaped tissue that surrounds the tube connecting the larynx with the lungs. The first is dubbed "recurring" for ITS irregular path, such as the climb in the area between the wind called the trachea and the food tube named the esophagus, when diving into the area between the head and the abdomen referred to as the chest. The inner nerve nerve nerve is an inner branch of the superior larynx. Both organ systems are responsible for the delivery of the larynx.

6 could be cough uncontrollably if the inner larynx nerve is irritated by food particles or water trapped in pyriform sinus. This is the most common in infants and in some cases it may develop in a bacterial infection called acute infectious thyroiditis. Also, the paralysis of the organ from which it springs from the upper nerve of the upper larynx changes the voice playground to the hoarse and could burn with permanent if it stays for a few months.

pyriform sinus is associated with neck and head cancer. It is located in the pituitary or lower part of the neck that connects to the esophagus called the pharynx. In approximately 70 percent of all cases of hypopharyngeal cancer, tumors are specially located in pyriform sinus. Since it is difficult to diagnose, the cancer of hypopharyngeal cancer in Stage III is usually discovered, suggesting significant disease progression and reducing the chance of survival.
