[Clinical and morphological bases of inferior exterior tarsopexy]

Involution processes caused by elongation of the lower eyelid are associated with loss of elastic fibers, destruction of collagen fibers, and fibrous degeneration of the distal fragment of the tarsal plate. The authors present a morphological validation of resection of the lower pedicle of the external ligament of the eyelid and shortening of the lateral part of the tarsal plate. Modified suture fixation to the orbital external wall periosteum and external retinaculum is proposed, ensuring adequate tension of the lower eyelid. High functional efficiency of the operation is analyzed on 66 clinical cases; the incidence of complications was low and good cosmetic results were attained (period of observation 3-52 months).
