When Should Adults Have Their Tonsils Removed? An ENT in Gangnam, Seoul Explains

Answered by Dr. Kim Yoo Suk, MD · Board-certified otolaryngologist · Former professor, Yonsei & Ajou University · Consultations in English

The main reasons for adult tonsillectomy

The tonsils are two pads of lymphoid tissue at the back of the throat that help fight infection in childhood. In adults, they play a smaller role in immunity, and removing them when they cause repeated problems does not weaken the immune system in a meaningful way. Based on our clinic's criteria, tonsillectomy is typically considered for:

• Recurrent tonsillitis: about four to five or more episodes a year, especially when they cause missed work and require antibiotics.
• Obstructive sleep apnea: when enlarged tonsils narrow the airway during sleep.
• Peritonsillar abscess: a collection of pus beside the tonsil, particularly if it has happened before.
• Suspected tumor: one tonsil much larger than the other, an ulcer, or abnormal appearance.

Chronic tonsillitis with persistent sore throat and bad breath, or frequent bothersome tonsil stones, can also be discussed case by case.

Why adults think carefully before surgery

Tonsillectomy in adults is effective for the right reasons, but recovery is generally harder than in children. Expect:

• Significant throat pain for about one to two weeks, often with ear pain
• A soft, cool diet during healing
• Time off work, commonly around two weeks
• A risk of bleeding, most often around 5 to 10 days after surgery when the scabs fall off

Because of this, the decision should be based on documented frequency and severity, not on a single bad episode.

Keep a tonsillitis record

Write down the date of each episode, whether you had fever, whether a doctor saw white patches or swollen neck glands, and whether antibiotics were prescribed. This record is often the most important factor in the decision.

What we do at Gangnam Yonsei ENT

Dr. Kim Yoo Suk, a board-certified otolaryngologist and former assistant professor at Ajou University School of Medicine, evaluates the tonsils, neck, and airway. If snoring or sleep apnea is a concern, the assessment may include a sleep study. A laryngoscopy may be added when symptoms extend to the voice box or throat below the tonsils.

If tonsillectomy is appropriate, the procedure, the setting in which it is performed, recovery, and risks are explained in detail so you can plan time off. For milder cases, medical management of each episode and watchful waiting may be recommended instead, in keeping with the clinic's principle of performing only treatment that is needed.

When to seek urgent care

Go to a doctor right away if you have severe one-sided throat pain, difficulty opening your mouth, a muffled "hot potato" voice, drooling, or trouble breathing or swallowing. These can signal a peritonsillar abscess or other deep neck infection.

Related questions

Will removing my tonsils weaken my immune system?

In adults, the tonsils play a limited role in immunity, and many other lymphoid tissues continue to protect the body. Research has not shown a meaningful long-term weakening of immunity after tonsillectomy performed for appropriate reasons.

How painful is tonsillectomy for adults?

Adults commonly experience significant throat pain for one to two weeks, sometimes with ear pain. Regular pain medication, cold fluids, and a soft diet help. Pain usually peaks in the first week and then gradually improves.

Can I have tonsillectomy for snoring alone?

If snoring is mainly caused by large tonsils, tonsillectomy can reduce it. However, snoring often has several causes, including the nose, palate, and tongue base. A full airway evaluation, and often a sleep study, comes first.
