An adenoidectomy removes the adenoids, a mass of tissue behind the nose and throat. Adenoids can become enlarged due to frequent infections or allergies and may cause snoring, nasal obstruction, mouth breathing, or chronic ear infections. This procedure is often performed in children, sometimes alongside tonsillectomy.

Adenoidectomy is done under general anesthesia and is performed through the mouth, so there are no external incisions. It is a short and safe procedure, often done as outpatient surgery. Most children recover quickly, with only mild sore throat or nasal congestion for a few days. Breathing through the nose typically improves, and snoring often decreases. Risks are low but can include bleeding, infection, or a temporary nasal-sounding voice as the throat adjusts. Follow-up is usually straightforward; most adults and children return to school or work within a few days.
