What is it? The thoracic outlet is the small area between the collarbone and the first rib and contains many blood vessels, nerves and muscles. More information on Physiopedia Here.

Injury of the facial nerve with resultant facial muscle paralysis may result in other significant complications such as corneal ulceration. To the authors' knowledge, neurotization to the facial nerve using the long thoracic nerve LTN , a nerve used previously for neurotization to other branches of the brachial plexus, has not been explored previously. In an attempt to identify an additional nerve donor candidate for facial nerve neurotization, 8 adult human cadavers 16 sides underwent dissection of the LTN, which was passed deep to the clavicle and axillary neurovascular bundle. The facial nerve was localized from the stylomastoid foramen onto the face, and the distal cut end of the previously dissected LTN was tunneled to this location. Measurements were made of the length and diameter of the LTN. Long thoracic nerve innervation to the first and second digitations of the serratus anterior was maintained on all sides.

In this article, we shall look at the anatomy of the facial nerve — its anatomical course, functions and clinical correlations. The facial nerve is associated with the derivatives of the second pharyngeal arch :. The course of the facial nerve is very complex. There are many branches, which transmit a combination of sensory, motor and parasympathetic fibres. The nerve arises in the pons , an area of the brainstem.
