Dissection of ear from lateral aspect
Relation of right auricular cartilage to external auditory meatus; terminal branches of great auricular nerve
The posterior auricular muscle has been cut and the auricular cartilage retracted laterally.
  1. Lesser occipital nerve
  2. Posterior auricular muscle (cut across)
  3. Auricular branch vagus nerve
  4. Aberrant slip of posterior auricular muscle
  5. Occipital branch of posterior auricular nerve
  6. Posterior auricular nerve
  7. Sternocleidomastoid muscle (superficial fascia reflected)
  8. Upper pointer: Superior auricular muscle Lower pointer: Temporal fascia
  9. Helix
  10. Tragal plate
  11. External acoustic meatus (opened posteriorly)
  12. Conchal eminence
  13. Posterior branch greater auricular nerve
  14. Cartilaginous acoustic meatus
  15. Communication between posterior auricular nerve and greater auricular nerve
  16. Upper pointer: Antitragicohelical fissure Lower pointer: Tail of helix
  17. Branch facial nerve (to intrinsic muscles of auricle)
  18. Parotid gland
  19. Greater auricular nerve
