What is Tonsillectomy?

Surgical removal of tonsils is called tonsillectomy. Tonsils are located in the back of the throat and are a part of our immune system that defends the body from infections. Tonsillectomy is usually performed on children.

A tonsillectomy is performed under general anaesthesia and takes about 20 – 30 minutes. In the most common method, the surgeon removes tonsils using a scalpel. Other tonsillectomy methods include using coblation, radio frequency ablation, or CO2 laser to remove tonsils.

A tonsillectomy has no adverse effect on the body’s immunity.
