An Aesthetic Orbicularis Oculi Myectomy Technique for Blepharospasm: Use of Topical 5-Fluorouracil and Fibrin Sealant.

PURPOSE: To describe a modified technique of orbicularis oculi myectomy for refractory blepharospasm. This technique includes removal of orbicularis muscle, reformation of the eyelid crease and pretarsal platform using fibrin sealant (Tisseel), and topical 5-fluorouracil to reduce scar formation and improve aesthetic outcome.

METHODS: Retrospective chart review of 7 patients who underwent bilateral orbicularis oculi myectomy with our technique from 2013 to 2016. Outcome measures were postoperative botulinum toxin dose, frequency, duration between treatments, the amount of lagophthalmos, severity of dry eye, and patient satisfaction with aesthetic and functional outcome.

RESULTS: Patients who underwent the aesthetic myectomy technique had significantly decreased botulinum toxin use with relief of symptoms postoperatively. Only 1 of 7 patients experienced mild dry eye symptoms postoperatively, managed with artificial tears. All patients were satisfied with the aesthetic and functional outcome.

CONCLUSIONS: The aesthetic myectomy technique provides effective treatment for blepharospasm with good functional and aesthetic outcome.
