Tonsilla tubaria

The tonsilla tubaria ( tubal tonsil ) is an accumulation of lymphatic tissue in the form of a tonsil at the mouth of the Eustachian tube ( tuba auditiva , ear trumpet) in the lateral wall of the nasopharynx ( nasopharynx ) and belongs to the lymphatic ring of the pharynx . It is often imprecisely referred to as the torus tubarius , a fold of the mucous membrane that is raised by the tubular cartilage over the mouth of the Eustachian tube. The tonsilla tubaria occurs in humans and in cloven-hoofed animals (e.g. cattle, sheep, goats, pigs); in many other mammals it is not developed.

If this tonsil becomes enlarged, the Eustachian tube can swell, so that the pressure balance between the outside world and the middle ear is no longer guaranteed. The consequences are a feeling of pressure on the ear and a hearing loss that can be classified as a sound conduction disorder .
