What suffix refers to a cutting operational surgery?

The suffix that refers to a cutting operational surgery is -otomy. This suffix is derived from the Greek word "tomia," meaning "to cut." In the context of surgical procedures, it indicates an incision or cutting into a part of the body without necessarily removing it. For example, a laparotomy refers to an incision into the abdominal cavity, while a tracheotomy involves cutting into the trachea to facilitate breathing.

Other suffixes listed might suggest surgical procedures but have different specific meanings. The suffix -ectomy refers to the surgical removal of a specific part, such as in appendectomy, which means the removal of the appendix. The suffix -otomy generally encompasses making cuts or incisions, while -plasty refers to the surgical repair or reconstruction of a part, such as in rhinoplasty, which is the surgical reshaping of the nose. Thus, -otomy accurately describes procedures where cutting is central, making it the correct choice in this context.
