Which neck dissection removes levels I–V lymph nodes along with the sternocleidomastoid muscle, internal jugular vein, and spinal accessory nerve?
- A Modified radical neck dissection Type I
- B Radical neck dissection ✓
- C Selective neck dissection (supraomohyoid)
- D Extended radical neck dissection
Explanation
Radical neck dissection (Crile's dissection) removes all five lymph node levels (I–V) together with the three non-lymphatic structures: sternocleidomastoid muscle, internal jugular vein, and spinal accessory nerve (CN XI). Modified radical neck dissection preserves one or more of these structures. Selective neck dissection removes only specific nodal levels. Extended radical neck dissection includes additional structures such as the carotid artery or parotid.
