Also called cerebellar tonsillar ectopia, or tonsillar herniation. Abnormal findings include bright-red, enlarged tonsils or white or yellow tonsillar exudate. Acute tonsillitis is the most common manifestation of tonsillar disease. If not treated promptly, epidural hematomas can cause tonsillar herniation, resulting in respiratory arrest. All the patients were histological diagnosed and proven cases of tonsillar carcinoma. Obstructive tonsillar hypertrophy is currently the most common reason for tonsillectomy. Head trauma increases risk of cerebellar tonsillar ectopia by a factor of 4. Elevated ICP may result in uncal or tonsillar herniation, with resulting life-threatening brain stem compression. Tonsillectomy may be indicated if bad breath due to tonsillar stones persists despite other measures. The carcinoma may occur in one or more sites deep within the tonsillar crypts. For further evaluation of tonsillar herniation, CINE flow studies are used. CT scan may reveal nonspecific calcified images in the tonsillar zone. Symptoms tend to be worsened on bimanual palpation of the styloid through the tonsillar bed. Together this set of lymphatic tissue is called the tonsillar ring or Waldeyer's ring. They may be relieved by infiltration of lidocaine into the tonsillar bed.
