METHOD OF SURGICAL TREATMENT OF UPPER EYELID PTOSIS WITH ABSENCE OF LEVATOR FUNCTION IN CHILDREN

摘要

FIELD: medicine.;SUBSTANCE: preliminary marking in the area of the eyelid and forehead is performed. Skin minicuts are made in accordance with the marking: two cuts in the area of the eyelid and two cuts in the superciliary area, one cut in the central zone of the forehead. Tunnels are successively formed through the cuts with the simultaneous passing of a suspending material. A disposable needle 18G is used for spinal anaesthesia. Formation of the tunnels and passing of the suspending material are carried out under the orbicular muscle on the anterior surface of the tarsal plate and further along the levator. Ends of the suspending material are brought into the cut on the forehead skin. The upper eyelid is pulled to place its edge on the upper limbus. After that the ends of the suspending material are fixed to the frontal muscle. A polypropylene thread is used as the suspending material.;EFFECT: safety and accuracy of fixing material passing, reduction of a risk to injure surrounding tissues, preservation of the anatomical location of the upper eyelid tissues, improvement of the functional and cosmetic result of surgical treatment due to the small diameter of the tunnels, formation of a pentagonal closed contour, formation of the tunnels and passing the threads strictly under the orbicular muscle, application of the polypropylene thread.;4 dwg, 1 ex
