While the typical course of the facial nerve after exiting the stylomastoid foramen is presented, there is potential for anatomical variation in each patient.
The chorda tympani nerve is the largest branch of the facial nerve in the intrapetrous compartment; it splits from the facial nerve just before it exits via the stylomastoid foramen.
The facial nerve (FN) emerges extracranially through stylomastoid foramen and then proceeds anteriorly as covered by the parenchymal tissues of the parotid gland.
The only difference between the anatomy of the facial nerve in infants compared with adults is in the region of the stylomastoid foramen.
If the lesion is at the stylomastoid foremen it may result in facial paralysis only.4
The right facial nerve was exposed and crushed at its exit from the stylomastoid foramen proximal to the bifurcation of the main trunk.
Treatment often consists of a dose trial of antibiotics, antiviral or anti-inflammatory agents and in some cases, surgical decompressive procedures at the facial nerve exit zone (stylomastoid foramen) may be considered (Holland and Weiner, 2006).

On the left side, the soft tissue was seen extending along the styloid process into the stylomandibular tunnel up to the deep lobe of parotid gland, involving the extracranial segment of the left facial nerve below the level of stylomastoid foramen.
