was changed:
The lingual tonsils are aggregations of lymphoid follicles that mediate B- and T-cell lymphocytes, which serve a role in formulating the immune system. They are covered by stratified squamous non-keratinizednonkeratinized epithelium and contain deep crypts and mucosal glands. They form a part of the Waldeyer ring of mucosa-associated lymphoid tissue (MALT) of the oropharynx.
Location
- posterior third of the dorsum of the tongue
Blood Supply
lingual artery: a branch of the external carotid artery
tonsillar branch of the facial artery
- ascending pharyngeal branch of the external carotid artery
Nerve Supply
- tonsillar branch of glossopharyngeal nerve (CN IX)
Complications
- squamous cell carcinoma of the lingual tonsil
- sleep apnoea exacerbation
