METHOD FOR SURGICAL TREATMENT OF LOWER EYELID TWISTING OF SPASTIC AND INVOLUTION ETIOLOGY Russian patent published in 2020 - IPC A61F9/07 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to ophthalmology, and is applicable for treatment of inversion of lower eyelid of spastic and / or involution etiology. Lower eyelid comprises a subciliary skin incision 2–3 mm from the ciliary edge. Incision is made starting from a projection of the lachrymal point to an external edge of eyelid with 10–15 mm extension to a lateral edge of the orbit in the horizontal direction. Further, the skin graft is separated, immobilized along the entire perimeter of the incision to the edge of the orbit. Pretarsal part of the orbicularis oculi muscle is separated throughout the lower eyelid. Strip of the pretarsal part of the orbicularis oculi muscle with width of 2 mm is excised. At this stage, the ciliary edge occupies the correct position relative to the eye, and can be a guide for determining the required excision volume of the skin flap. Patient is asked to look up. Skin graft is returned to its former place without tensioning. Excess skin is excised by a projection of the initial section. Continuous intradermal, cosmetic suture is applied.

EFFECT: method enables minimizing trauma of orbital and eyelid tissues due to delicate excision of minimum volume of orbicularis oculi muscle, achieving stable long-term effect due to the possibility of determining the required excision volume of the muscular and skin flap, eliminating the risk of such postoperative complication as ectropion, for the purpose of this operation, hospitalization and anesthesia is not required.
