Free Functional Platysma Transfer for Restoration of Spontaneous Eye Closure in Facial Paralysis.

Background: Facial palsy patients experience an array of problems ranging from functional to psychological issues. With regard to the eye, lacrimation, lagophthalmos, and the inability to spontaneously blink are the main symptoms and, if left untreated, can compromise the cornea and vision. This article reports the outcomes of 23 free functional vascularized platysma transfers used for reanimation of the eye in unilateral facial paralysis.

Methods: Data were collected prospectively for all patients undergoing reanimation of the paralyzed eye using free functional platysma transfer. The only exclusion criterion was that a minimum of a 2-year follow-up was required. Patients were assessed preoperatively and postoperatively and scored using the eFACE tool focusing on eye-symmetry with documentation of blink reflex.

Results: A total of 26 free functional platysma transfers were completed between 2011 and 2018; three patients were excluded because of inadequate follow-up. The mean age was 9.1 ± 7.1 years and there were 12 boys and 11 girls. Preoperatively, no patients had evidence of a blink reflex in comparison to 22 patients at 2-year follow-up. There was a statistically significant improvement in palpebral fissure ( P < 0.001) and full eye closure ( P < 0.001) scores at 2-year follow-up; however, there was no statistically significant difference in gentle eye closure ( P = 0.15).

Conclusions: This is the first report of free functional platysma long-term outcomes in eye reanimation. The results demonstrate that successful restoration of the blink reflex can be achieved and full eye closure is obtainable following surgery.

Clinical Question/level Of Evidence: Therapeutic, IV.
