ENT · Head and neck: neck dissection

Sample item

Which structures are preserved in a type III modified radical neck dissection?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Sternocleidomastoid, internal jugular vein and spinal accessory nerve

Radical neck dissection removes levels I to V together with SCM, internal jugular vein and spinal accessory nerve. Type III modified radical dissection preserves all three, reducing morbidity such as shoulder syndrome.

Option by option

  • A. Only the internal jugular vein

    Preserving only the vein does not match any standard type of modified radical neck dissection.

  • B. Only the spinal accessory nerve

    Preserving only the spinal accessory nerve describes a type I dissection.

  • C. None of them

    Removing all three is a classical radical neck dissection.

  • D. Sternocleidomastoid, internal jugular vein and spinal accessory nerve (correct)

    Correct. Type III preserves all three structures.
