On either side of the laryngeal orifice in humans is a recess, termed the pyriform sinus (also piriform recess, piriform sinus, piriform fossa, or smuggler’s fossa), which is bounded medially by the aryepiglottic fold, laterally by the thyroid cartilage and thyrohyoid membrane. The fossae are involved in speech.
The piriform sinus, also commonly spelled pyriform sinus, is a feature of the pharynx, or human throat. It is contained in the hypopharynx, which is the lower portion of the pharynx that is found between the hyoid bone on the front of the neck and the lower border of the cricoid cartilage where the larynx, or voice box, begins.
The pyriform sinus is the anterolateral recess of the hypopharynx. The anterior pyriform sinus mucosa abuts on the posterior paraglottic space. The most caudal portion of the pyriform sinus lies at the level of the true vocal cords. The lateral aspect of the aryepiglottic folds forms the medial wall of the pyriform sinus (Fig. 2-59).
Pyriform sinus is the recess tissue lying between the trachea and the esophagus. Since there is a lot of open space in your neck, tumors can extensively grow before they present any symptoms. The pyriform sinus is located int the region of the neck known as HypoPharynx.
The pyriform sinus (also spelled piriform sinus and also known as the pyriform recess, pyriform fossa, and smuggler’s fossa) is the pear-shaped subsite of the hypopharynx located posterolaterally to either side of the laryngeal opening.
Pyriform sinus is associated with neck and head cancer. It is located in the hypopharynx, or the lower part of the throat region that joins to the esophagus called the pharynx. In about 70 percent of all hypopharyngeal cancer cases, the tumors are specifically located in the pyriform sinus.
Piriformis syndrome is a rare entrapment neuropathyresulting in radicular pain radiating into the buttock and hamstrings. The entity is controversial as are the putative causes.

Sinusitis is swelling of the sinuses, usually caused by an infection. It’s common and usually clears up on its own within 2 to 3 weeks. But medicines can help if it’s taking a long time to go away. Check if you have sinusitis
The piriform sinus, also termed recessus, or fossa, pyrifomis, is occasionally described as being part of the larynx, but, since it lies outside of that organ, is, strictly speaking, part of the hypopharynx. It appears as a deep depression between the cricoid and arytenoid cartilages and the posterior surface of the thyroid cartilage on each side of the larynx. It is situated beneath the …
