Introduction • Derived from words para—otid • Resembles three sided inverted pyramid
Parotid region • Front • Behind • Above • Below • Medial
Parotid Gland • Coverings • True capsule • False capsule (Parotid sheath)
Base Superficial surface Anterior border Posterior border Apex Presenting parts • Apex • Base • Superficial surface (lateral) • Antero-medial surface • Postero-medial surface • Anterior border • Posterior border • Medial border
Relations • Apex—extends downward into carotid triangle • Base :- external ear and temporomandibular joint
Lateral surface : • Covered by skin ,superficial fascia • Parotid lymph nodes • Anteromedialsurface : • Ramus of mandible with masseter and medial pterygoid
Posteromedialsurface • Related to mastoid process with sternomastoid and posterior belly of digastric
Structures passing through the gland • Facial nerve • Retro-mandibular vein • External carotid artery
Parotid duct • Stensen’s duct • 5 cm long • Anterior border of gland • Pierces • Buccal pad of fat • Buccopharyngeal fascia • Bucinator • Mucous membrane of vestibule
Applied anatomy • Inflammatory swelling of the gland • Mumps • Parotid abscess • Tumors of parotid gland • Frey’s syndrome
