Cautery dissection in levator surgery.

This report describes a new technique that facilitates dissection of tissue planes and essentially eliminates intraoperative bleeding, two of the most frequently encountered problems during levator surgery. The described technique has been used in more than 450 consecutive eyelids with congenital and acquired ptosis requiring levator surgery. Disinsertion or dehiscence of the aponeurosis was found in less than 5% of the cases of involutional ptosis.
