The torus tubarius (or torus of the auditory tube) is an elevation of the mucous membrane of the nasal part of the pharynx formed by the underlying base of the cartilaginous portion of the Eustachian tube (auditory tube). The torus tubarius is situated behind the pharyngeal orifice of the auditory tube.^[1]

The torus tubarius is very close to the tubal tonsil,^[1] which is sometimes also referred to as the tonsil of (the) torus tubarius.^[2] Two folds run anteriorly and posteriorly to the torus tubarius: the salpingopalatine fold (anteriorly), and the salpingopharyngeal fold (posteriorly).

-The base of the cartilaginous portion of the [[Eustachian tube]] ([[pharyngotympanic tube]]; [[auditory tube]]) lies directly under the [[mucous membrane]] of the [[nasal part of the pharynx]], where it forms an elevation, the '''torus tubarius''', the '''torus of the auditory tube''', or cushion, behind the pharyngeal orifice of the tube. The torus tubarius is very close to the [[tubal tonsil]],<ref>http://download.videohelp.com/vitualis/med/pharynx.htm</ref> which is sometimes also called the ''tonsil of (the) torus tubarius''.<ref>http://www.almaany.com/home.php?language=english&lang_name=English&category=Medical&word=tonsil+of+torus+tubarius++%3D++tubal+tonsil</ref> Equating the torus with its tonsil however might be seen as incorrect or imprecise.

-*anteriorly, the second and smaller fold, the [[salpingopalatine fold]], smaller than the salpingopharyngeal fold, is made by a few delicate fibers of muscle, it stretches from the superior lateral border of the cartilage to the palate anteroinferiorly near the junction of the two parts, hard and soft; Simkins (1943)<ref name="test" /> designated the salpingopalatine fold, and referred to the muscle as the ''salpingopalatine muscle''.The [[tensor veli palatini]] does not contribute to the fold, since the origin is deep to the cartilaginous opening.
