Facial symmetry is one of the most important aesthetic features of the face and a challenge for all surgeons. Facial asymmetry can have a bone, soft tissue, neuromuscular changes or mixed origin. The facial nerve, VII cranial nerve, is responsible for facial expression and its injury can lead to facial paralysis.
Facial paralysis is a clinical condition that can have a major psychological impact on patients' lives. When the facial nerve is compromised, we may have several facial motor alterations:
- difficulty closing the eyelids
(leaving the eye exposed, and there may be irreversible lesions)
- difficulty smiling
- difficulty speaking or eating
- difficulty kissing
- facial asymmetry
Its manifestation starts in an acute way, with facial alterations in less than 72 hours. It may be accompanied by hypersensitivity to sounds, pain in the pinna or dry eyes.
