Treatment of essential blepharospasm. I. Comparison of facial nerve avulsion and eyebrow-eyelid muscle stripping procedure.
Benign essential blepharospasm is an incurable disease for which many treatment modalities have been suggested. The two surgical procedures that have been used most commonly are avulsion of the facial nerve and stripping of the protractor muscles of the eyelid and brow. We compare two matched series of 22 patients; one group underwent facial nerve avulsion ("Reynold's" procedure), and the other underwent "muscle stripping" ("Anderson's" procedure). We noted the number of procedures required for the patient to obtain a functional visual result and the side effects produced. Additional surgical procedures required by patients undergoing facial nerve avulsion were additional facial nerve avulsion, repair of ectropion, and correction of dermatochalasis and brow droop. Additional procedures required in patients who had muscle stripping were excision of lower lid orbicular fibers or residual brow fibers. The Reynold group required 16 additional procedures (38 separate procedures) to obtain functional results, as opposed to the four additional procedures (26 separate procedures) required in the Anderson group. Two patients in the Reynold group who needed surgery have not yet undergone it at this writing. If they did, that would boost the total number of procedures to 40. Secondary procedures are needed 4.5 times more often with the Reynold procedure than with the Anderson procedure. The patient's subjective response to and acceptance of the procedure are much greater for the Anderson procedure.
