Chronic adenotonsillitis is the condition of a persistent infection of the tonsils and adenoids. Again this may be due to streptococcal bacteria (strep throat) or bacteria draining from the nose and sinuses. The hallmark of chronic adenotonsillitis is a failure of the symptoms to resolve with adequate antibiotic therapy. Again Penicillin or Amoxicillin are the first choices in non-allergic individuals, with Erythromycin or Bactrim reserved for Penicillin allergic individuals. When the first line antibiotics fail, progressively broader spectrum antibiotics should be used (i.e. Cedax or Suprax, Augmentin or Zithromax). Tonsillectomy and adenoidectomy should be considered when at least three different antibiotics, including a broad spectrum choice, have been tried for at least two weeks each, and symptoms still persist. CT scan should be done as it is advised,its radiation no doubt,other than this its safe.
