Which of these procedures involves the removal of adenoids?

The procedure that involves the removal of adenoids is adenoidectomy. This surgical operation specifically targets the adenoid tissues, which are located at the back of the nasal cavity and can become enlarged, leading to breathing difficulties, sleep disturbances, or recurrent infections.

Adenoidectomy is often performed in children who experience chronic conditions related to their adenoids, such as frequent ear infections or sinusitis. By removing the adenoids, healthcare providers can alleviate these symptoms and improve overall respiratory function.

In contrast, a tonsillectomy refers to the removal of the tonsils, which are different lymphatic tissues located in the throat. An appendectomy is the surgical removal of the appendix and is unrelated to adenoids. A lobectomy involves the surgical removal of a lobe, often in the lungs or brain, and also does not pertain to adenoids. Thus, adenoidectomy is the only choice that specifically describes the removal of the adenoids, making it the correct answer.
