Facial relations, posterolateral view
The sternocleidomastoid muscle has been retracted posteriorly and the parotid gland displaced anteriorly. Lymphatic vessels and nodes are closely related to the part of the carotid sheath which covers the internal jugular vein.

2 . Superficial branch facial nerve (cut across)
3 . Posterior facial vein
4 . Angle of mandible
5 . Masseter muscle
6 . Parotidomasseteric fascia
