METHOD FOR CORRECTION OF PARALYTIC EVERSION OF LOWER EYELID Russian patent published in 2014 - IPC A61F9/07 

FIELD: medicine.

SUBSTANCE: exterior canthotomy and cantholysis are performed. Two bone holes are formed in the upper external border of an orbit. That is followed by creating a looped canal in an intraorbital region and the middle area of a face with its beginning and end at the upper external border of the orbit. The medial portion of the canal is found in a space between subcutaneous fat and a muscular layer, while its lateral portion is supraperiosteal. A non-absorbable suture is delivered through the canal with its ends brought out through the formed bone holes; soft tissue lifting of a midface and an infra-orbital region by suture ends is combined with hypercorrection of the tissue lifting and suture fastening. An inferior exterior tarsopexy, a partial exterior tarsorrhaphy are performed, and then the excess skin is resected within the exterior canthotomy. A periosteum of an anterior maxillary surface is additionally dissected and separated along the edge of the orbit at 15 mm downwards, passing over an infra-orbital neurovascular bundle; that is followed by performing periosteal lifting with soft tissues; after that, the periosteum is shortened along the edge of an inferior wall of the orbit and fixed to the orbital edge or bone. Additional canals are formed as a loop spaced at 3 mm from each other. Either an allosuture, or an autosuture, or a heterosuture is used as a non-absorbable suture. A transversally notched monofilament suture is used.

EFFECT: long-term effect of correction of eversion of the lower eyelid with no injuries of the medial angle of the eye with simultaneous satisfactory cosmetic effect on the side of prosoplegia.
