  • Facial nerve.

  • Retro-mandibular vein.

  • External carotid artery – bifurcating into its two terminal branches, the maxillary artery and the superficial temporal artery.

From here proceed downwards and backwards to a point 1 cm in front of the angle of the mandible. Then continue upwards and backwards 1–2 cm into the neck including the mastoid process. Finally draw your line around the ear to join up to the point from where we started. You will now have drawn a shape that approximates the position of the parotid.

What are the potential complications of parotid surgery?

  • Facial nerve damage.

  • Haematoma.

  • Frey's syndrome (gustatory sweating).

  • Numbness of the pinna (due to sacrifice of the greater auricular nerve).

  • Wound dimple.
