Filter by: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.
Main research purposes of this research is to compare the therapeutic effect and safety of the superior levator muscle shortening combined with the tarsus resection and the traditional frontal muscle flap in the correction of severe ptosis. Aside of above we also tend to explore the dose-effect relationship between the amount of levator muscle shortened/ tarsus resection and postoperative ptosis correction amount.So as to develop a more critical and specific guidelines for clinical treatment of ptosis. So during the research we will recruiting patients with severe ptosis and randomly divide them into levator muscle and tarsus group and frontal muscle flap group, and follow up those patient 6 months post operation so as to evaluate the amount of correction and the side-symptoms.
