[Prospects for using the Mullerectomy for correcting ptosis of the upper eyelid]

New anatomic topographic and clinical validation of mullerectomy is presented and more comprehensive evaluation of preoperative adrenergic drug test is suggested. Morphological substantiation of an isolated resection of the superior tarsal muscle (Müller muscle) and orbital conjunctiva of the upper eyelid with subsequent fixation of the proximal part of Müller muscle to the tarsal plate is presented. The results of surgical treatment of 51 patients evidence high reliability, functional and cosmetic efficiency of mullerectomy which does not involve a skin incision, and a low incidence of complications (mean period of observation 35 months).
