Subjective and objective outcome measures in the treatment of facial nerve synkinesis with onabotulinumtoxinA (Botox).
To evaluate the Sunnybrook Facial Grading System (SFGS) and Facial Clinimetric Evaluation Scale (FaCE Scale) instrument outcome measures pre- and 30-day posttreatment of facial nerve synkinesis with botulinum toxin with attempts to correlate the 2 scales. ⋯ Significant improvement was seen in objectively reported synkinesis following botulinum toxin therapy. An improvement was noted in the overall subjective facial nerve functioning following therapy along with improvement in social functioning and facial comfort. A meaningful negative correlation was noted when comparing the SFGS "synkinesis" subdomain with the FaCE scale subdomain "eye comfort", implying improvement in eye comfort with control of synkinesis.
