METHOD FOR RESTORING EXTENSIVE SOFT TISSUES DEFECTS OF THE MIDDLE FACE AND LOWER EYELID Russian patent published in 2020 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to reconstructive-plastic surgery. Injured tissues are removed with resection of a lower eyelid, a nasolacrimal canal, a conjunctiva of the lower eyelid with a lachrymal flesh and restoration of the integrity of the middle zone. Autologous tissues are represented by a bilge-cheek-neck crotch flap and a mucous flap. To close the skin defect, the bilge-cheek-neck flap is separated by a cut from an external angle of the eye in the projection of the zygomatic bone and continues to the preauricular region, where the incision is rounded and brought downward in the preauricular furrow, then the incision is continued to the ear lobes, enveloped, switched to the mastoid process and then downwards along the sternocleidomastoid muscle, pass to the upper cervical fold of the skin and continue for another 3-4 cm along the natural fold. Internal incision is also made from an external edge of the nostril and is led along a nasolabial fold and to an angle of the mouth. Cut out the bilge-cheek-neck flap on the pedicle unfolded on the defect area and sutured with the face defect edges. Then a conjunctiva of the lower eyelid is formed, for which a free mucous flap is cut out from the cheek, which is stitched together with a bilge-cheek-neck skin flap, then in the postoperative period immobilisation is performed by stapling eyelids between each other.

EFFECT: method enables one-stage plastic surgery of the middle face and eyelid area with cover of extensive defects of soft tissues with application of patient's autogenous tissues, homogeneous by color, thickness and consistence of autogenous tissues, as well as provides reconstruction of tissues of the middle face area in the volume, preventing subsequent scar deformation and enables to perform the following corrective interventions in order to achieve maximum cosmetic effect.
