How do you do auricular block?
- Place patient in supine or sitting position.
- Disinfect skin at the base and superior aspect of ear using chosen antiseptic.
- Insert needle into the skin just inferior to the attachment of the earlobe to the head.
- Advance needle just anterior to the tragus, aspirate while advancing.
What is auricular nerve block?
A greater auricular nerve (GAN) block was used as the sole anesthetic for facial surgery in an 80-year-old male patient with multiple comorbidities which would have made general anesthesia challenging. The GAN provides sensation to the ear, mastoid process, parotid gland, and angle of the mandible.
What anesthesia is used for digital blocks?
However, Bradon Wilhelmi and colleagues demonstrated the safety and efficacy of epinephrine-containing local anesthetic for digital block. Digital block is one of the most common nerve block techniques.
Can you inject lidocaine into earlobe?
Local anesthetic agents (eg, lidocaine 1% [Xylocaine], bupivacaine 0.25% [Marcaine]) may be used. If a regional block is performed, lidocaine mixed with epinephrine can be used; however, epinephrine is contraindicated in direct infiltration of the ear.
How do you block a greater auricular nerve?
The greater auricular nerve and the lesser occipital nerves can be blocked distally over the mastoid process posterior to the ear. The needle is inserted behind the lower lobe of the ear and advanced following the curve of the posterior sulcus.
How much anesthesia is in a digital block?
Slowly inject about 1 mL of anesthetic to block the dorsal digital nerve. Then continue to advance the needle downward into the palmar space, while slowly injecting another 1.5 mL of anesthetic to block the palmar digital nerve. Take care not to penetrate the palmar aspect of the finger.
Is a digital block considered local anesthesia?
The digital nerve block is a procedure in which an anesthetic solution is injected into the base of a finger or toe to provide regional anesthesia. Other methods to anesthetize locally the tissues of the digits vary from applications of topical agents to subcutaneous injections of anesthetic solutions.
Where should you not inject lidocaine?

It is at this point that the greater auricular nerve is blocked utilizing an in-plane approach by advancing a 22-gauge, 1½-inch needle in proximity to the superficial portion of the nerve ( Fig. 6.8 ). A paresthesia may be elicited, and the patient should be warned of such.
What is ultrasound-guided Greater auricular nerve block?
Ultrasound-guided greater auricular nerve block is most commonly utilized in conjunction with lesser occipital nerve and auriculotemporal nerve block to provide complete surgical anesthesia and/or postoperative pain relief for the surgery of the external ear.
What is the role of auriculotemporal nerve block in pain relief?
Additional nerve block of the auriculotemporal nerve is as, if not more effective, more direct, and provides equivalent analgesia using less anesthetic agent.
Do nerve blocks work for ear lacerations?
This works well for various regions of the face, such as the infraorbital nerve block for lacerations below the eye. However, the ear is innervated by multiple cranial nerve branches and cervical nerve roots.
