Facial synkinesis is the long-term sequela of facial nerve injury that
can result in severe deficits in facial expression and function. It is
characterized by abnormal involuntary facial movements that accompany
voluntary facial expressions. The type and severity of symptoms differ
from patient to patient, which makes evaluation and management complex.
Given the chronicity of the disease, appropriate evaluation is paramount
to effective management. This article will discuss how to effectively
evaluate patients in the office and associated treatment.
