Sometimes, both the tonsils and adenoids become swollen and infected. The removal of both glands at the same time is known as a tonsilloadenoidectomy. Not everyone who needs an adenoidectomy will require tonsil removal and vice versa. Doctors base the decision to remove either or both of these glands on the child’s specific symptoms and medical history. Children who tend to have swelling of both the tonsils and adenoids may be good candidates for a tonsilloadenoidectomy.
