An adenoidectomy is the surgical removal of the adenoid glands. These are located between the nasal airway and the back of the throat (nasopharynx). Adenoidectomies are frequently performed at the same time as removal of the tonsils, a procedure known as a tonsillectomy.

Sometimes, ear tube surgery (myringotomy) will be performed in conjunction with an adenoidectomy. This is done to prevent recurring ear infections, which can be caused by allergies. 

Adenoids may become chronically infected and enlarged, leading to the following conditions:

• Breathing problems.
  
  
• Swallowing problems.
  
  
• Chronic bouts of tonsillitis.
  
  
• Obstructive sleep apnea (OSA), a disorder that causes breathing to temporarily stop during sleep.
  
  
• Chronic ear infections.
  
  
• Recurring ear infections (otitis media).
  
  
• Recurring sinus infections.
  
  
• Chronic snoring.

Physicians may recommend adenoidectomy to help alleviate these conditions. The majority of adenoidectomies are performed in children. The adenoids usually shrink by adolescence, so adults rarely undergo adenoidectomies. Occasionally the procedure is performed on adults for snoring problems.

Adenoidectomies are usually performed on an outpatient basis. After a recovery period (usually one to two weeks), patients experience benefits such as easier breathing through the nose, fewer ear infections and fewer sore throats.
