Radical neck dissection involves all except ?
**Core Concept**
Radical neck dissection is a surgical procedure that involves the removal of lymph nodes and other structures in the neck, typically performed to treat or prevent the spread of cancer. The procedure aims to eliminate the primary site of cancer and surrounding lymphatic tissue.
**Why the Correct Answer is Right**
The correct answer involves identifying the structures that are typically spared during a radical neck dissection. The procedure involves the removal of lymph nodes, the sternocleidomastoid muscle, the internal jugular vein, and the spinal accessory nerve. However, the hypoglossal nerve is usually preserved to maintain facial function and prevent complications such as difficulty with speech and swallowing.
