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 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 does the posterior auricular nerve innervate?

The posterior auricular nerve (PAN) is the first extracranial branch of the facial nerve trunk. It innervates the posterior belly of the occipitofrontalis and the auricular muscles and contributes cutaneous sensation from the skin covering the mastoid process and parts of the auricle.

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).

What does the auricular nerve do?

Anatomical terms of neuroanatomy The great auricular nerve originates from the cervical plexus, composed of branches of spinal nerves C2 and C3. It provides sensory innervation for the skin over parotid gland and mastoid process, and both surfaces of the outer ear.

Does great auricular nerve supply scalp?

The lateral section of the posterior scalp is supplied by the lesser occipital and great auricular nerves, branches of the cervical plexus (see Fig. 72-5).

Is the auricular nerve a cranial nerve?

The posterior auricular nerve is an extracranial branch of the facial nerve, cranial nerve VII, that supplies relatively small muscles of the head and neck.

Which nerve is responsible for auricle?

The auricular branch of the vagus nerve is often termed the Alderman’s nerve or Arnold’s nerve. The latter name is an eponym for Friedrich Arnold. The auricular branch of the vagus nerve supplies sensory innervation to the skin of the ear canal, tragus, and auricle.

Can neuralgia affect the ear?

Geniculate neuralgia results in severe, deep ear pain which is usually sharp—often described as an ice pick in the ear—but may also be dull and burning. Ear pain can also be accompanied by facial pain. This pain can be triggered by stimulation of the ear canal, or can follow swallowing or talking.

What is the best painkiller for neuralgia?

The anti-convulsant drug most commonly prescribed for trigeminal neuralgia is carbamazepine (Tegretol), which can provide at least partial pain relief for up to 80 to 90 percent of patients. Other anti-convulsants prescribed frequently for trigeminal neuralgia include: Phenytoin (Dilantin) Gabapentin (Neurontin)

Can trigeminal neuralgia cause earache?

Trigeminal neuralgia is a nerve disorder of the face. It causes abrupt, searing facial pain, especially in the lower face and jaw and around the nose, ears, eyes, or lips. Also known as tic douloureaux,it is thought to be one of the most painful human conditions.

What nerves transmit the sensation of pain from the auricle?

The posterior auricular nerve accompanies the posterior auricular artery and supplies the muscles of the auricle together with the occipitalis. The superior and anterior auricular muscles however are innervated by the temporal branches of the facial nerve.

What is auricle ear?

The medical term for the outer ear is the auricle or pinna. The outer ear is made up of cartilage and skin. There are three different parts to the outer ear; the tragus, helix and the lobule. EAR CANAL. The ear canal starts at the outer ear and ends at the ear drum.

Where are posterior auricular lymph nodes?

The mastoid lymph nodes (retroauricular lymph nodes or posterior auricular glands) are a small group of lymph nodes, usually two in number, located just beneath the ear, on the mastoid insertion of the sternocleidomastoideus muscle, beneath the posterior auricular muscle.

Do I need to see a neurologist for occipital neuralgia?

Occipital neuralgia can be very difficult to diagnose because of its similarities with migraines and other headache disorders. Therefore, it is important to seek medical care when you begin feeling unusual, sharp pain in the neck or scalp and the pain is not accompanied by nausea or light sensitivity.

What is the lingual nerve?

The lingual nerve is one of the sensory branches of the mandibular division of the trigeminal nerve. [5] It contains general somatic afferent nerve fibers and, after chorda tympani joins it, also carries general visceral efferent nerve fibers and special visceral afferent fibers.

What is the mandibular nerve?

The mandibular nerve supplies the teeth and gums of the mandible, the skin of the temporal region, part of the auricle, the lower lip, and the lower part of the face (see Figure 4-2, V3). The mandibular nerve also supplies the muscles of mastication and the mucous membrane of the anterior two-thirds of the tongue.

What is the Postauricular region?

post·au·ric·u·lar Denotes area located behind the auricle (external part of the ear).

What is the Postauricular area?

Medical Definition of postauricular : located or occurring behind the auricle of the ear a postauricular incision.

What are auricular muscles?

The auricular muscles are vestigial in humans and few individuals can move their ears voluntarily. As a result, the auricular muscles are generally considered to be of little functional significance, although auricular reflexes activate ear muscles during eye movements (Urban et al., 1993).

What is the hypoglossal?

The hypoglossal nerve enables tongue movement. It controls the hyoglossus, intrinsic, genioglossus and styloglossus muscles. These muscles help you speak, swallow and move substances around in your mouth.

What is Tragal pointer?

The “cartilaginous pointer” or “tragal pointer”: the anterior tip of the tragus portion of the external ear cartilage. The main trunk is reported to be 1 cm deep and inferior to the pointer. … The main trunk is reported to be 6 to 8 mm from the inferiomedial end of this suture line.

What is Retromandibular vein?

The retromandibular vein, also known as the posterior facial vein, is a deep vein of the face that is formed by the merger of the superficial temporal vein with the maxillary vein. It runs within the substance of the parotid gland, descending posterior to the ramus of the mandible.

What are the branches of greater auricular nerve?

The great auricular nerve gives off two terminal branches:

  • The anterior branch, also called the facial branch, which innervates the skin over the parotid gland. …
  • The posterior branch, also called the mastoid branch, which supplies the skin over the mastoid process and the posterior surface of the auricle.

What is the nerve in front of the ear?

After leaving the brain the facial nerve enters the temporal bone (ear bone) through a small bony tube (the internal auditory canal) in very close association with the hearing and balance nerves.

Where is the vagus nerve located in the ear?

Vagus nerve branches in the jugular foramen The auricular branch supplies sensations to the posterior aspect of the external ear (pinna) and the posterior part of the external auditory canal. It arises also from the superior ganglion and enters the mastoid canaliculus in the lateral part of the jugular foramen.

Can the vagus nerve cause ear pain?

Glossopharyngeal, nervus intermedius, and vagus neuralgias can all present with ear pain.

Can mastoiditis be cured?

Mastoiditis can be cured if treated with antibiotics right away. It may come back periodically (recur) in some individuals. If infection spreads, serious complication can arise including hearing loss, bone infection, blood clots, brain abscess, and meningitis.
