What Is a Power-Assisted Adenoidectomy?

The adenoids are a single clump of tissue that’s very high in the back of your throat, behind your nose. It is believed that the adenoids help trap germs so they can’t get further into the body.

Sometimes, however, the adenoids may cause ear infections when the trapped bacteria travel up the Eustachian tube to the middle ear. In some cases, the trapped germs make the adenoids swell and block the Eustachian tube, causing fluid and bacteria to build up in the middle ear.

During a power-assisted adenoidectomy, the surgeon uses a special instrument called a microdebrider (MY-cro-duh-BRY-der). It has a tiny rotating tip for removing the enlarged adenoids.

The microdebrider has a curved tip which helps the surgeon put the instrument where it’s needed to remove the adenoids.
