Abstract:
Synkinesis is a sequela of moderate to severe facial palsy, caused by aberrant nerve regeneration. It leads to involuntary co-movements, impaired facial expression, and thus reduced quality of life. Treatment includes facial therapy, EMG biofeedback, botulinum toxin (BTX-A), and, in selected cases, surgery. This case report presents a case from Rigshospitalet demonstrating symptom relief and improved facial symmetry after treatment with BTX-A injections and facial therapy. Synkinesis is a complex condition that requires a multidisciplinary approach. Early detection, prevention and appropriate referral are crucial.
