Throat Treatments

Tonsillectomy

Tonsillectomy is the surgical removal of the tonsils, two oval-shaped pads of tissue at the back of the throat — one tonsil on each side.

A tonsillectomy was once a common procedure to treat infection and inflammation of the tonsils (tonsillitis). Today, a tonsillectomy is usually performed for sleep-disordered breathing but may still be a treatment when tonsillitis occurs frequently or doesn't respond to other treatments.

A tonsillectomy may also be necessary to treat breathing and other problems related to enlarged tonsils and to treat rare diseases of the tonsils.

Why it's done

• Recurring, chronic or severe tonsillitis
• Complications of enlarged tonsils
• Bleeding of the tonsils
• Other rare diseases of the tonsils

Tonsillitis

The tonsils are the immune system's first line of defense against bacteria and viruses that enter your mouth. This function may make the tonsils particularly vulnerable to infection and inflammation. However, the tonsil's immune system function declines after puberty — a factor that may account for the rare cases of tonsillitis in adults.

A tonsillectomy may be recommended to prevent frequent, recurring episodes of tonsillitis. Frequent tonsillitis is generally defined as:

• At least seven episodes in the preceding year
• At least five episodes a year in the past two years
• At least three episodes a year in the past three years

The procedure may also be recommended if:

• A bacterial infection causing tonsillitis doesn't improve with antibiotic treatment
• An infection that results in a collection of pus behind a tonsil (tonsillar abscess) doesn't improve with drug treatment or a drainage procedure
