Dissection of ear from lateral aspect
Relation of right auricular cartilage to external auditory meatus; terminal branches of great auricular nerve
The posterior auricular muscle has been cut and the auricular cartilage retracted laterally.
1 . Lesser occipital nerve
2 . Posterior auricular muscle (cut across)
3 . Auricular branch vagus nerve
4 . Aberrant slip of posterior auricular muscle
5 . Occipital branch of posterior auricular nerve
6 . Posterior auricular nerve
7 . Sternocleidomastoid muscle (superficial fascia reflected)
8 . Upper pointer: Superior auricular muscle Lower pointer: Temporal fascia
9 . Helix
10 . Tragal plate
11 . External acoustic meatus (opened posteriorly)
12 . Conchal eminence
13 . Posterior branch greater auricular nerve
14 . Cartilaginous acoustic meatus
15 . Communication between posterior auricular nerve and greater auricular nerve
16 . Upper pointer: Antitragicohelical fissure Lower pointer: Tail of helix
17 . Branch facial nerve (to intrinsic muscles of auricle)
