Combining Early Lower Eyelid Surgery With Neuromuscular Retraining for Synkinesis Prevention After Facial Palsy.

Facial synkinesis (FS) is a distressing sequela of facial palsy (FP) characterized by involuntary, simultaneous movements of facial muscles occurring during voluntary facial expressions. Treatment of synkinesis is challenging, and preventive methods are needed.

This study evaluates the efficacy of physical facial nerve rehabilitation (PFNR) therapy alone versus PNFR with eyelid surgery to correct lagophthalmos and prevent the onset of synkinesis.

25 outpatients are randomized to receive either PFNR alone (neuromuscular retraining and Kabat proprioceptive neuromuscular facilitation) or PNFR and early (90 days after FP onset) eyelid surgery (involving a conservative oculoplastic correction for lagophthalmos with epiphora or ectropion). Comprehensive otolaryngological assessments and Magnetic Resonance Imaging (MRI) will be conducted. Synkinesis progression was measured using Another Disease Scale (ADS) at baseline, 3 months 6 months, 12 months, and 24-months post-treatment. The data were analyzed with ANOVA, t-test, Chi-Square analyses.
