For children, the adenoids (also known as a pharyngeal tonsil or nasopharyngeal tonsil), are usually removed at the same time, a procedure called adenoidectomy, or tonsilloadenoidectomy, when combined.
en.wikipedia.org Carried out through the mouth under a general anaesthetic, adenoidectomy involves the adenoids being curetted, cauterised, lasered, or otherwise ablated.
en.wikipedia.org Depending on the cause of obstruction, surgery may focus on the soft palate, the uvula, tonsils, adenoids or the tongue.
en.wikipedia.org Adenoids can also obstruct the nasal airway enough to affect the voice without actually stopping nasal airflow altogether.
