METHOD FOR RESTORATION OF EYE CORNEA TROPHISM ACCOMPANYING NEUROTROPHIC KERATOPATHY Russian patent published in 2020 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to maxillofacial surgery and ophthalmology. Coronary incision of skin and subcutaneous fat is performed to the periosteum. Temporal parietal flap is separated from it, reaching the surface plates of the temporal fascia. Folding tip temporomandibular flap in front side. Periosteum is dissected away from the upper and orbital edges by 8–11 cm. Periosteum is separated from the frontal bone to the upper and orbital edges and the bony pyramid of the nose. Supraorbital and/or supra-lateral nerves are released from the orifices of the eye socket. On the healthy side of the temporomandibular flap, 4–8 branches of the supraorbital and/or supra-lateral nerves are separated with further temporomandibular flap placed in place. Tunnel in the temporomandibular flap is formed on the involved side of the periosteum of the upper medial edge of the eye socket to the upper conjunctival arch of the upper eyelid. Further, in points of conjunctival and tenon capsule around corneal limb in sclera, corneoscleral tunnels are formed by conducting 3–5 perileimbal incisions of sclera with width of 2–4 mm in layer 1/3–1/2 of its thickness with subsequent stratification of sclera tissues and cornea in direction from limb to centre of cornea at 1–2 mm and fixation of fascicles of branches of supraorbital and/or superciliary nerves in formed corneoscleral tunnels.

EFFECT: method allows increasing functional and aesthetic effects, reducing the risk of traumatism of the supraorbital and/or supra-lateral nerves, facilitating their germination into the thickness of the cornea of the eye, preventing scar deformation in the upper eyelid.
