After an episode of facial paralysis, as nerves recover, they aberrantly regenerate and send additional branches to the incorrect muscles in addition to the intended muscle. This leads to what is known as Aberrant Regeneration Syndrome, Post-paralysis Synkinesis, or Nonflaccid Facial Paralysis. It is characterized by poor facial symmetry and function, hypertonic facial muscles at rest, and abnormal facial movements. One sequela is acquired blepharoptosis causing a smaller ocular aperture, visual field obstruction, cosmetic deformity, and abnormal periocular spasms. This study aims to evaluate an FDA approved medication for acquired blepharoptosis due to synkinesis/hyperkinesis as an adjunct to treatment.
