Effect of Upper Eyelid Myectomy on Subsequent Chemodenervation in the Management of Benign Essential Blepharospasm

摘要

Purpose: Some patients with severe benign essential blepharospasm (BEB) become clinically refractory to chemodenervation with botulinum toxin. In these patients, surgical myectomy is an effective additive treatment for the management of this disabling condition. The purpose of this study is to determine how myectomy for BEB alters subsequent botulinum toxin administration.
