Great Auricular Neuralgia. Description: A disorder characterized by unilateral brief stabbing pain, abrupt in onset and termination, in the distribution of the great auricular nerve (preauricular, parotid and jaw angle and/or posteroinferior pinna and mastoid).
What is neuralgia pain?
Neuralgia is a stabbing, burning, and often severe pain due to an irritated or damaged nerve. The nerve may be anywhere in the body, and the damage may be caused by several things, including: aging. diseases such as diabetes or multiple sclerosis.
What are the 2 cranial nerves that communicate with great auricular nerve?
Branches and supply
- a small lateral branch of the posterior branch pierces the auricle to supply the lobule and concha.
- the posterior branch of the greater auricular nerve communicates with the lesser occipital nerve, auricular branch of the facial nerve and posterior auricular branch of the facial nerve.
What type of nerve is an auricular nerve?
Anatomical terms of neuroanatomy The great auricular nerve is a cutaneous nerve of the head. It originates from the cervical plexus, with branches of spinal nerves C2 and C3. It provides sensory nerve supply to the skin over the parotid gland and the mastoid process of the temporal bone, and surfaces of the outer ear.
Where is the auricular nerve located?
The greater auricular nerve can be found between the angle of the mandible and the tip of the mastoid process on the lateral surface of the sternocleidomastoid muscle,37 posterosuperior to the external jugular vein (Fig. 30-9). The nerve can be harvested through an oblique skin incision placed in a skin crease.
What is the origin of greater auricular nerve?
The great auricular nerve is from the cervical plexus as a superficial branch, originating from the second and third cervical vertebral levels (C2–C3). The great auricular nerve exits the cervical plexus at the posterior aspect of the sternocleidomastoid muscle at a point called Erb’s point.
What triggers neuralgia?
Neuralgia has many possible causes, including: infections, such as shingles, Lyme disease, or HIV. pressure on nerves from bones, blood vessels, or tumors. other medical conditions, such as kidney disease or diabetes.
How do you know if you have a great auricular nerve?
The great auricular nerve (GAN) is shown deep to the SMAS flap and immediately superficial to the belly of the SCM. Lateral border of the superficial musculoaponeurotic system (SMAS)–platysma flap just medial to the anterior border of the sternocleidomastoid (SCM).
Where does the great auricular nerve originate?
cervical plexus
The great auricular nerve is from the cervical plexus as a superficial branch, originating from the second and third cervical vertebral levels (C2–C3). The great auricular nerve exits the cervical plexus at the posterior aspect of the sternocleidomastoid muscle at a point called Erb’s point.
What is the great auricular nerve function?
The great auricular nerve (GAN) is a superficial branch of the cervical plexus that provides sensory innervation to the skin overlying the parotid gland, external ear, and posterior auricular region.
What is the great auricular nerve?
The Great Auricular Nerve ( n. auricularis magnus) is the largest of the ascending branches.
What is the function of the anterior and posterior auricular nerve?
Great auricular nerve – Nervus auricularis magnus. The anterior branch ( ramus anterior; facial branch) is distributed to the skin of the face over the parotid gland, and communicates in the substance of the gland with the facial nerve. The posterior branch ( ramus posterior; mastoid branch) supplies the skin over the mastoid process and on…
How common is neuralgia of Gano?
GAN damage is well described with procedures nearby the nerve course. However, neuralgia of this nerve is uncommon, and its knowledge is based on a handful of case reports.
What does the auricle innervate?
Arises as branch of cervical plexus, conveying fibers from ventral primary rami of second and third cervical spinal nerves; supplies skin of part of auricle, adjacent portion of scalp, and that overlying angle of jaw; also innervates parotid sheath, conveying from it pain fibers stimulated by stretching of the sheath during parotitis (mumps).
