Definition:
A "septectomy" is a medical term that refers to a surgical procedure where all or part of a septum is removed. A septum is a wall or barrier that separates two spaces in the body. For example, the nasal septum divides the two nostrils in your nose, and the atrial septum separates the two upper chambers of the heart.
In advanced medical discussions, "septectomy" might be used in relation to specific conditions or types of surgeries. For instance, a "septoplasty" is a specific type of septectomy that focuses on correcting a deviated nasal septum.
While "septectomy" specifically refers to the surgical removal of a septum, the term "septum" itself can refer to various structures in different parts of the body, including the heart and nasal passages.
There are no direct idioms or phrasal verbs related to "septectomy," as it is a specialized medical term. However, you might hear phrases like "go under the knife," which means to have surgery, in a more general context.
In summary, "septectomy" is a term used to describe a surgical procedure that involves removing a septum in the body, often to improve conditions related to breathing or heart function.
