What does a craniotomy involve?

A craniotomy specifically involves the surgical incision into the skull, which allows access to the brain for various procedures. This is often performed to remove tumors, relieve pressure, or repair damaged tissues. The term "craniotomy" itself combines "cranio," meaning skull, and "otomy," which refers to the act of cutting or making an incision. In contrast, the other options refer to different medical procedures or conditions that do not pertain to the direct access to the brain through the skull, which is the primary focus of a craniotomy. Understanding the definition and purpose of a craniotomy is essential for clarity in surgical coding and inpatient healthcare contexts.
