Background
- External ear innervated by four sensory nerves
- Greater auricular nerve
- Lesser occipital nerve
- Auricular branch of vagus nerve
- Auriculotemporal nerve
- Provides anesthesia to the entire ear without distorting anatomy
Indications
- Repair of lacerations
- I+D of hematoma or abscess, or other painful procedures involving the external ear
Contraindications
- Infection at injection site
- Allergy to chosen anesthetic
Equipment
- Syringe, 5-10cc
- Needle, 25-27 gauge
- Local anesthetic (e.g. lidocaine 1%, bupivacaine 0.25%)
- Lidocaine with epinephrine may be used for regional block, but epi should not be used for direct infiltration of the ear
- Antiseptic (e.g. Betadine, Chlorhexidine, Alcohol)
- Sterile gloves
