Previous work (13) using MRI scanning in assessing lingual tonsil hypertrophy has been confined to its use for evaluating obstructive sleep apnoea.
This elucidated that the cause of the difficulty was lingual tonsil hypertrophy.

Lingual tonsil hypertrophy as a cause of dysphagia is unusual.
In light of the nonspecific symptoms and the difficulty encountered in examining the area, a high index of suspicion is necessary to adequately diagnose and treat dysphagia caused by lingual tonsil hypertrophy.
The patient then underwent an upper endoscopy, which revealed that the lingual tonsils were greatly enlarged and that there was a slight irregularity of the mucosa in the upper one-third of the esophagus.

      [ edit on Wikidata ]

      The lingual tonsils are two small mounds of lymphatic tissue located at the back of the base of the tongue , one on either side. They are composed of lymphatic tissue that functions to assist the immune system in the production of antibodies in response to invading pathogenic bacteria or viruses .

      Structure[ edit ]

      Microanatomy[ edit ]

      Lingual tonsils are covered externally by stratified squamous nonkeratinized epithelium. The epithelium invaginates inward to form a single crypt. Beneath the epithelium is a layer of lymphoid nodules containing lymphocytes. These tonsils are surrounded by thin capsule of connective tissue which separates them from adjacent structures. Mucous glands located at the root of tongue are drained through several ducts into the crypt of lingual tonsils. Secretions of these mucous glands keep the crypt clean and free of any debris. Therefore, the lingual tonsils are less prone to infection.

      Blood supply[ edit ]

      Lingual tonsils are located on posterior aspect of tongue which is supplied through:

      • Lingual artery, branch of external carotid artery
      • Tonsillar branch of facial artery
      • Ascending pharyngeal branch of external carotid artery

      Nerve supply[ edit ]

      Lingual tonsils are innervated by tonsillar branches of glossopharyngeal nerve.That is located at the back of the tongue.

      Function[ edit ]

      Tonsils and the throat–lingual tonsils labelled

      Like other lymphatic tissues, the function of lingual tonsils is to prevent infections. These tonsils contain B and T lymphocytes which get activated when harmful bacteria and viruses come in contact with tonsils. B lymphocytes kill pathogens by producing antibodies against them, while T lymphocytes directly kill them by engulfing them.

      Clinical significance[ edit ]

      Cancer[ edit ]

      Squamous cell carcinoma of lingual tonsils can occur in people above 50 years of age.[ citation needed ]

      Sleep apnea[ edit ]

      Enlarged or hypertrophic lingual tonsils have the potential to cause or exacerbate sleep apnea.[ citation needed ]
