Parotid gland is the largest of the three major

salivary glands.

Boundaries of the parotid gland include:

• Superior – zygomatic arch

• Posterior – external acoustic meatus and

sternocleidomastoid muscle

• Anterior – masseter muscle

The facial nerve (CN VII) pierces the parotid gland

and separates the gland into the superficial and

deep lobes:

• Superficial lobe – lateral to CNVII

• Deep lobe – medial to CNVII
