The GAN can be injured during many procedures in the head and neck, resulting in a significant negative impact on the patient's quality of life. Invasive stimulation of the vagal nerve previously demonstrated a reduced risk of POAF. Genitofemoral Nerve. The incision of the skin about the ear lobe may injure the small superficial branches of the great auricular nerve. The efficacy of this anatomical knowledge has since been tested extensively by scientists all over the world who have measured the effect of stimulating the auricular branch of the vagus nerve (ABVN) at both the tragus and the cymba conchae. Greater Auricular Neuralgia. [1] This nerve consists of anterior and posterior branches providing sensory innervation to the skin overlying the parotid gland, outer ear, and mastoid process. The great auricular nerve is a superficial cutaneous branch of the cervical plexus, providing sensory innervation to the skin of the parotid and periauricular region. Cervical spine.

rugby). It passes vertically upward over the sternocleidomastoid muscle (SCM) providing sensory innervations for the skin of auricle, lower face, and upper neck. Cervical plexus. It is perhaps the most commonly injured nerve when performing a facelift. Superficial cervical plexus. Post-operative edema and traction neuropraxia may result in temporary tingling and numbness; however, the dilemma is differentiating a recoverable injury from a nerve which is severed. 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 sensory innervation arises from the great auricular and lesser occipital nerves both branches of the second (C2) and third (C3) branches of the cervical plexus, the auriculotemporal nerve from the mandibular branch of the trigeminal nerve and the auricular branch of the vagus nerve known as Alderman's or Arnold's nerve. boy with pontine tegmental cap dysplasia and bilateral trigeminal anesthesia. This term has been used to describe pain in the territory of the greater auricular nerve i.e. 42%. The SCM is separated from the brachial plexus and the scalene muscles by the prevertebral fascia, which can be seen as a hyperechoic linear structure. The great auricular nerve (GAN) leaves the C2-C3 cervical rami, wraps around the sternocleidomastoid muscle, then divides into: anterior branch (skin over preauricular, parotid, jaw angle) and posterior branch (skin over mastoid and posteroinferior pinna).

Artificial modulation of the afferent vagus nerve - a powerful entrance to the brain - affects a large number of physiological processes implicating interactions between the brain and body. Background: The great auricular nerve (GAN) originates from the cervical plexus at the levels of C2 and C3, supplying sensation to the skin overlying the lower aspect of the pinna and angle of the mandible. motor and sensory) nerve, but mainly it's motor. Conventionally, surgeons have sacrificed the great auricular nerve (GAN) during parotidectomy to facilitate access to the parotid gland. 1 Studies 2-4 have shown that GAN sensory loss can lead to anesthesia, paresthesia, discomfort, functional deficits (eg, difficulties wearing earrings and handling the telephone), an increased risk of traumatic injury, and an increase risk of neuromas. The Great Auricular Nerve (GAN) is a key anatomical landmark during most of the head and neck surgical procedures. This is required in many parotidectomy procedures. Over time, the area of numbness will shrink, but the lobule of the ear will remain numb forever if the greater auricular nerve was sacrificed during surgery. Facial Nerve.
