Which artery may cause significant bleeding during surgery involving the sternocleidomastoid muscle?

• A. Maxillary artery
• B. Internal jugular vein
• C. External jugular vein
• D. Facial artery

Answer: (C)

The external jugular vein is located superficially in the neck and runs along the surface of the sternocleidomastoid muscle. When performing surgical procedures involving this muscle, such as dissections or resections, the external jugular vein can be at risk of being punctured or transected, which may lead to significant venous bleeding. Understanding the anatomy and its relationship to surgical approaches is crucial for minimizing complications. The external jugular vein frequently collects venous drainage from regions of the face and neck, and its exposure during surgery particularly highlights the potential for considerable blood loss if inadvertently injured. While the other structures mentioned are vascular or venous as well, they have different locations or functions that make them less critical in terms of direct injury during surgery focused around the sternocleidomastoid muscle. The maxillary artery, while important, primarily supplies deeper structures and is not as closely associated with the surface anatomy of the sternocleidomastoid. The internal jugular vein is positioned deeper and more medial, while the facial artery runs along the mandible and is not typically encountered in procedures involving the sternocleidomastoid. Thus, the external jugular vein stands out as a significant concern for potential bleeding during such surgical
