Variation in Branching Pattern of Facial Nerve in the Face

 After departing the skull at the stylomastoid foramen, the facial nerve enters the parotid gland high on its posteromedial surface and continues forward and downwards beyond the mandibular ramus. Within the parotid substance, it separates into superior (temporofacial) and inferior (cervicofacial) trunks, resulting in five principal peripheral branches reaching out across the face. Within the parotid gland, these branches diverge and depart by the anteromedial surface, medial to anterior edge, to supply the facial expression muscles. During normal dissection of the head and neck region for medical undergraduates in the Department of Anatomy, Punjab Institute of Medical Sciences, Jalandhar, India, the face of an 86-year-old embalmed female corpse was dissected. We discovered a difference in the branching pattern of the facial nerve on the right side of the face, as well as a comparable pattern on the left, after careful dissection. The difficulty for head and neck surgeons doing parotid surgery is to remove the tumour while preserving the functional and anatomical integrity of all branches of the facial nerve. As a result, in order to do successful surgery, surgeons must be aware of the differences.
