point where greater auricular nerve
exits behind the posterior border of sternocleidomastoid muscle) using 2ml of 2% lignocaine with 1; 100,000 epinephrine subcutaneously at this point with gentle massage after injection.
The cervical plexus consists of the ventral primary divisions of the first four cervical spinal nerves and gives rise to (1) the muscular branches, including the phrenic nerve and nervus descendens cervicalis, as well as (2) the sensory branches, including the lesser occipital, transverse cutaneous, supraclavicular, and great auricular nerves
Longitudinal swelling on the right-side of neck (left side arrow) representing thickened greater auricular nerve
, which seems to apparently feed a well to ill-defined hypopigmented patch (right side arrow) on the cheek and neck.
The site was corresponding to the route of Greater Auricular Nerve
in the neck.
The author hypothesized that the use of this procedure to remove a benign pleomorphic adenoma might result in even less morbidity (transient or permanent facial nerve dysfunction, facial contour disfigurement, Frey's syndrome, and hypoesthesia) without increasing the risk of recurrence if only a 1-cm margin of normal parotid parenchyma was removed and if the posterior branches of the great auricular nerve
On examination severe tenderness of the ulnar nerves and right greater auricular nerve
During the course of the dissection, the frontal branch of the nerve was transected, and a graft from the ipsilateral great auricular nerve
was used to repair it.
the posterior auricular branch--which innervates the auricularis posterior, the cranially oriented muscles of the auricle, and the occipital muscles--communicates with the greater auricular nerve
, the auricular branch of the vagus nerve, and the lesser occipital nerve (3)
Sharma and co-workers reported a leprotic abscess formation in the great auricular nerve
created a free osteocutaneous fibula flap to reconstruct the mandible and grafted the great auricular nerve
to the facial nerve branches (figure 5).
2,3) The incidence of these abscesses is higher in males and the commonest nerve involved is the ulnar nerve, with the greater auricular nerve
being the most commonly affected sensory nerve.
The most frequently affected nerve trunks are the ulnar (in the medial fossae of the olecranon epicondyle), the radial nerve (in the radial fossae), the common peroneal (lateral popliteal) nerve, the median nerve (at the carpal tunnel), the auricular nerve
at the lateral side of the neck, and the posterior tibial behind the medial malleolus, all of them accessible to clinical examination.
The great auricular nerve
on the side of the neck, below the ear, is sometimes visibly enlarged: gently feel it to make sure it is the nerve (solid) and not one of the veins in the neck (full of fluid).
