METHOD FOR ELIMINATING SOFT TISSUE DEFECT IN OBLIQUE ORBITAL CLEFT OF THE FACE Russian patent published in 2021 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to maxillofacial surgery. The lines of the upcoming incisions are outlined in accordance with the size of the intact areas of the face. Excess tissue is isolated, then, after infiltration, incisions are made in the skin and muscles under the ciliary edge of the lower eyelid, retreating 1.5–2 mm downward from its border, extending beyond the outer border of the eye corner by 1.0–2.0 cm. On the outer edge of the split a fragment of the cheek, incisions are made in accordance with the outlined boundaries and taking into account the length of the slope of the nose of the healthy side.

Fragments of the circular muscle of the mouth and the edge of the skin wound are sutured in layers. The ciliary edge of the lower eyelid is hemmed to the eyebrow.

EFFECT: method allows restoring correct muscle activity and orientation of muscle fibers, redistributing tissue fixation zones, providing conditions for subsequent symmetrical functioning of facial muscles with a minimum number of scars, and ensuring achievement of bilateral functional symmetry.
