[Lid surgery (author's transl)].

From the anatomical and physiological point of view th eyelid may be divided into three layers: a deep layer, comprising the tarsi and the canthal tendons with the levator aponeurosis and the lower lid retractors, the orbicularis muscle layer, and the skin. The surgical particularities of each of these layers are outlined. In the management of eyelid injuries the meticulous reconstruction of the medial canthal tendon and canthus is of paramount importance. Only after this are the lids closed from medially to laterally and from deep to superficial tissues.
