Dissection of left temporal region

Posterior deep temporal nerve and artery; capsule of temporomandibular joint, lateral view

The temporal muscle (1) has been reflected anteriorly. Its tendon of insertion (7) remains in situ, although the coronoid process to which it attached has been cut away (20).

3. Posterior deep temporal nerve
4. Masseteric nerve
5. Upper pointer: Masseteric artery Lower pointer: Deep posterior temporal artery
6. Zygomatic arch (divided)
7. Tendon of temporalis muscle (note impression produced by coronoid process of mandible)
8. Buccal nerve
9. Temporal fossa
10. Middle temporal artery
11. Cartilaginous external acoustic meatus
12. Zygomatic arch (cut across)
13. Superficial temporal artery (cut off)
14. Upper pointer: Joint capsule of mandible Lower pointer: Temporomandibular ligament
15. Branches of auriculotemporal nerve
