adenoidectomy

This term is a specialized medical noun used primarily in clinical settings, such as otolaryngology and pediatrics. It describes a specific surgical procedure and carries a neutral, technical connotation. In a patient-facing context, a doctor might use the simpler phrase "removing the adenoids," but "adenoidectomy" is the standard term for medical records and professional communication.

As a medical procedure name, it is typically treated as a countable noun when referring to the instance of the surgery (e.g., "the patient had an adenoidectomy"). However, it is often used in the singular to describe the general surgical process.
