Figure 7.3 Parotid gland: (a) dissected specimen and (b) schematic diagram.

Superficial surface faces the skin and is covered by (a) skin, (b) superficial fascia containing the su- perficial parotid lymph nodes and posterior fibres of platysma, (c) parotid fascia and (d) few deep parotid lymph nodes within the gland. Anteromedial surface lies against the posterior border of ramus. The structures associated with this surface are masseter, medial pterygoid and emerging branches of facial nerve (Fig. 7.4). Posteromedial surface is adapted to the mastoid and styloid processes and the structures attached to them.

Surfaces and Relations It has four surfaces: 1. Superior 2. Superficial 3. Anteromedial and 4. Posteromedial (Fig. 7.4)

Superior surface is the base of the pyramid. It is small, concave and lies close to the external acoustic meatus and the posterior surface of the temporo- mandibular joint.
