[Recent developments and technics in eyelid-orbit surgery].

The advances in lid and orbital surgery are due to the improvements made in diagnostic equipment and to technical refinements. Modern imaging techniques now provide exact preoperative analyses, especially for orbital disorders. New suture and implant materials have been introduced, and the use of the operating microscope and of various types of lasers has broadened the spectrum of therapeutic possibilities. Surgical procedures have been developed that pay more attention to the specific anatomy, function and pathogenesis of the lids, especially for involutional disorders and loss of tissue.
