Where is the tonsillar fossa?
The tonsillar fossa or sinus is a triangular space between the anterior pillar in front, the posterior pillar behind, and the dorsal surface of the posterior one third of the tongue inferiorly (Figure 2). Because the tonsils are positioned in it, its borders also limit the tonsil [7].
What is tonsillar capsule?
Description. From the pharyngeal side, the palatine tonsils are covered with a stratified squamous epithelium (the tonsillar capsule), whereas a fibrous capsule links them to the wall of the pharynx. Through the capsule pass trabecules that contain small blood vessels, nerves and lymphatic vessels.
