Tonsillectomy for one enlarged tonsil ?

Hi, welcome to the ehealth forum and I am glad to help you.
You seem concerned about tonsillectomy. Tonsillectomy may be indicated when the patient:
1.Experiences recurrent infections of acute tonsillitis. The number requiring tonsillectomy varies with the severity of the episodes. One case, even severe, is generally not enough for most surgeons to decide tonsillectomy is necessary. According to the current guidelines (2000) of the American Academy of Otolaryngology & Head and Neck Surgery (AAO-HNS), tonsillectomy is indicated if a patient contracts "Three or more attacks of sore throat per year despite adequate medical therapy”.
2.Has chronic tonsillitis, consisting of persistent, moderate-to-severe throat pain.
3.Has multiple bouts of peritonsillar abscess.
4.Has sleep apnea.
5.Has difficulty eating or swallowing due to enlarged tonsils (very unusual reason for tonsillectomy)
6.Produces tonsilloliths (tonsil stones) in the back of their mouth.
7.Has abnormally large tonsils with crypts.
As far as your case is concerned indication number 7 may solve your confusion and accordingly you might benefit from tonsillectomy.
Hope this helps. Take care.
