Which suffix indicates a surgical repair?

The suffix that signifies a surgical repair is "-plasty." This term is derived from the Greek word "plastos," meaning molded or formed. In medical terminology, it is used to indicate surgical procedures that involve the reconstruction or repair of a part of the body. For example, rhinoplasty refers to the surgical repair or reshaping of the nose, and angioplasty refers to the repair or reconstruction of blood vessels.

In contrast, "-itis" denotes inflammation, typically of tissues or organs, and does not refer to any form of surgical intervention. The suffix "-philia" indicates a love or affinity for something, which is unrelated to surgical procedures. Lastly, "-metry" refers to the measurement of something, often used in diagnostic contexts, but does not imply any surgical repair. Thus, "-plasty" is the correct choice as it specifically connects to surgical repair and reconstruction in medical terminology.
