NCBI Bookshelf. Boston: Butterworths; The motor portion, or the facial nerve proper, supplies all the facial musculature. The principal muscles are the frontalis, orbicularis oculi, buccinator, orbicularis oris, platysma, the posterior belly of the digastric, and the stapedius muscle. In nuclear or infranuclear "peripheral" lesions, there is a partial to complete facial paralysis with smoothing of the brow, open eye, flat nasolabial fold, and drooping of the mouth ipsilateral to the lesion. Supranuclear "central" lesions spare the brow and eyelid musculature; there is flattening of the nasolabial fold and drooping of the mouth contralateral to the lesion.

Symptoms of facial nerve injury may vary due to age, facial anatomy and the extent of nerve-damage. Frequent patient concerns relate to brow position, movement abnormalities, eyelid closure issues, inability to smile, mid-facial asymmetries, poor oral function and lower lip asymmetry. A light degree of facial nerve weakness may only be visible as subtle asymmetries following repeated and exhausting muscle function, whereas severe dysfunction can be easily recognised even at rest. Many of these symptoms will change over time, for example following a spontaneous recovery of nerve function or as a result of different therapeutic modalities i. House-Brackmann HB is one of several analysis tools developed to quantify facial function and provide reproducible information.

The problem can affect one or both sides of the face, with noticeable drooping of the features and problems with speaking, blinking, swallowing saliva, eating or communicating through natural facial expressions. Paralysis of the face may be temporary or permanent.
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.
