What are the risks and complications associated with surgery for enlarged tonsils?

There is a risk of severe bleeding associated with tonsillectomy for enlarged tonsils, as well as possible complications such as taste disturbances, dental injury, and scar formation.

I. Risks

All surgical procedures carry certain risks. Because the tonsils have a rich blood supply, there is a potential risk of significant bleeding during surgery for enlarged tonsils. If an artery is damaged during the procedure, it may lead to severe hemorrhage, possibly resulting in hemorrhagic shock or asphyxiation. Therefore, it is recommended that patients remain hospitalized for several days after surgery for observation, which is relatively safer.

II. Complications

1. Taste disturbances

During surgery, the tongue depressor of the mouth gag exerts pressure on the surface of the tongue. Prolonged pressure may cause numbness of the tongue or delayed sensation in the lingual nerves, leading to taste disturbances. These symptoms typically resolve gradually after a period of rest.

2. Dental injury

The surgical procedure requires the use of a mouth gag to separate the upper and lower jaws, which may damage teeth, causing loosening or bleeding. In severe cases, tooth loss may occur. Patients can seek dental restoration as advised by their physician.

3. Scar formation

Tonsillectomy for enlarged tonsils may result in excessive scar tissue at the surgical site, affecting local aesthetics. Scarring on the inner side may also lead to difficulty swallowing. Patients may consider treatments such as laser scar removal under medical guidance.

Patients should carefully follow postoperative care instructions, maintain wound cleanliness, and avoid strenuous physical activity to prevent interference with wound healing.
