Which statement describes the relationship of Viborg's Triangle to the retromandibular space?

• A. It lies within the thoracic inlet
• B. It signifies a safe entry into the retromandibular space
• C. It encloses the parotid gland
• D. It is located on the ventral neck

Answer: (B)

Viborg's triangle is a surface landmark that marks a corridor over the lateral neck aligned with the retromandibular space. It provides a relatively safe entry point to reach behind the parotid gland and access the retromandibular vein/space, minimizing risk to the facial nerve branches that pass through or near the gland. The triangle sits on the lateral neck, not in the thoracic inlet and not on the ventral neck, and it does not enclose the parotid gland. It’s used to guide safe access to the retromandibular space, hence that description is the most accurate.
