The National Institute for Health and Clinical Excellence (NICE) has issued full guidance to the NHS in England, Wales, Scotland and Northern Ireland on Suction diathermy adenoidectomy.


Adenoids are small lumps of lymphoid tissue at the back of the nose, which are part of the immune system. They are largest in young children and usually disappear by adulthood. An adenoidectomy is an operation to remove the adenoids if they become enlarged and are thought to be causing health problems such as ‘glue ear’. Suction diathermy adenoidectomy is a type of surgery to remove the adenoids using heat and suction.
