What does the suffix "-otomy" signify in a medical context?

The suffix "-otomy" indicates a surgical procedure involving cutting into a part of the body. It is derived from the Greek word "tomia," meaning "to cut." When used in a medical term, it signifies that a surgical incision is being made to access the interior of an organ or cavity for examination or treatment.

For example, a "laparotomy" refers to an incision into the abdominal cavity, while a "tracheotomy" involves making an incision into the trachea to facilitate breathing. This understanding is crucial for anyone studying medical terminology, as it helps in interpreting a wide range of surgical procedures based on their naming conventions.
