INVOLUTIONAL ENTROPION REPAIR BY POSTERIOR LAMELLA TIGHTENING AND MYECTOMY

Involutional entropion is a common eyelid malposition of diverse etiol ogy that may recur after surgical repair. Laxity of the tarsoligamento us complex combined with posteriorly directed rotational force exerted by the orbicularis, in our view, seems to be the most important in th e production of entropion. A surgical technique has been developed tha t is carried out through a standard transcutaneous lower eyelid blepha roplasty incision. It includes tarsoligamentous tightening at the late ral canthus, bolstering of the lateral canthal tendon, and partial orb icularis myectomy. Forty-two procedures in 35 consecutive patients (29 % for recurrent entropion) have been performed and evaluated (mean fol low-up, 33 months). There have been no recurrences, and the esthetic o utcome has been very good.
