METHOD FOR LOWER EYELID PLASTY AND LATERAL COMMISSURE OF EYELIDS Russian patent published in 2024 - IPC A61F9/07 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to reconstructive surgery. Lower eyelid, one third of the upper eyelid, and the lateral commissure of eyelid are removed. Medial commissure of the upper eyelid is cut off. Subsequent cutting out of skin and fat flap is performed. Transposition fat skin flap is cut out in the zygomatic region at angle of 90 degrees to the eye fissure on the side of the lesion, as shown in Fig. 2, width and length are 20% more than the excised eyelid section. Base of flap is 0.5–1 cm above the level of the lateral angle of the eye; after mobilization, the flap is displaced upwards. Acute de-epithelisation of the "ciliary" side of flap 5 mm wide from the base to the tip of the flap. Further, the de-epithelised edge of the flap is sutured end-to-end to the medial commissure of the lower eyelid. Then the upper eyelid stump is dissected from its medial commissure on the conjunctival side and sutured laterally to the flap base. Flap is also anchored to the periosteum or the bone of the lateral wall of the orbit, thus forming a lateral commissure of the eyelids, and the de-epithelised edge of the flap is used to form the ciliary edges of the eyelids. Donor wound is sutured in the cheekbone area with Prolen 5-0 suture, keeping the pedicle within the lateral angle of the eye.

EFFECT: method allows to improve functional and aesthetic results of reconstruction of total lower eyelid defect occupying its entire volume and accompanied by germination of lateral commissure of eyelids, affection of lateral one-third of upper eyelid, tarsal plate and conjunctiva of both eyelids.
