The pyriform sinus (also piriform recess, piriform sinus, piriform fossa, or smuggler's fossa) is a small recess on either side of the laryngeal inlet. It is bounded medially by the aryepiglottic fold, and laterally by the thyroid cartilage and thyrohyoid membrane. [1] The fossae are involved in speech.

The piriform aperture, pyriform aperture, or anterior nasal aperture is a pear-shaped opening in the human skull. Its long axis is vertical, and narrow end upward; in the recent state it is much contracted by the lateral nasal cartilage and the greater and lesser alar cartilages of the nose .
Behind the ostium of the eustachian tube (ostium pharyngeum tuba auditiva) is a deep recess, the pharyngeal recess (fossa of Rosenmüller). Clinical significance
In anatomy, a fossa (/ ˈ f ɒ s ə /; [1] [2] pl.: fossae (/ ˈ f ɒ s iː / or / ˈ f ɒ s aɪ /); from Latin 'ditch, trench') is a depression or hollow, usually in a bone, such as the hypophyseal fossa (the depression in the sphenoid bone). [3]
The piriform cortex, or pyriform cortex, is a region in the brain, part of the rhinencephalon situated in the cerebrum. The function of the piriform cortex relates to the sense of smell . Structure
The Keros classification is a method of classifying the depth of the olfactory fossa. The depth of the olfactory fossa is determined by the height of the lateral lamella of the cribriform plate. Keros in 1962, classified the depth into three categories. [3] type 1: has a depth of 1–3 mm (26.3% of population)
This diagram shows the location of the subglottic region in the throat. The subglottis or subglottic region is the lower portion of the larynx, extending from just beneath the vocal cords down to the top of the trachea. [1]
