2. Auricle - PARTS
a/Cranial part of the auricle: Helix……………outer margin of the auricle Anthelix………large plane part the auricle. b/Caudal part of the auricle: Lobulus auriculae………free movable, soft. c/Inner part of the auricle: Tragus…….....…….………..localized against the helix, important cephalometric point.

3. Auricle – a/CRANIAL PART
Helix (No 6)
……………outer margin
of the auricle
Anthelix (No 4)
……large plane part

4. Auricle – b/CAUDAL PART
Lobulus auriculae
(No 1)
………free movable, soft

5. Auricle – c/INNER PART TRAGUS (No 12) PORUS ACUSTICUS EXTERNUS (No 11)
localized
against the helix
PORUS ACUSTICUS
EXTERNUS
(No 11)

6. INNER PART of the auricle →→→
● Porus acusticus externus
● Meatus acusticus externus
small sebaceous glands (product cerumen)
the cannal has two parts = cartilage + bone.
● → Membrana tympanica (Tympanic membrane).

7. Meatus acusticus externus

8. TISSUES forming the auricle
-Skin -The main substance is elastic cartilage (usable e. g. for autologous grafts in reconstructions). -The lobulus auriculae consits from fatt. -Muscles (of no value). Sensitive inervation = mostly by n. auricularis magnus (C 3).

9. AESTHETICS of the auricle
-Length of the auricle is approximately the same as length of the nose -angle with temporal region varies within 25 °– 45 °. Auricular anomalies = aplasia, hypoplasia, deformations.
