METHOD OF ELIMINATION OF CONGENITAL OR ACQUIRED DEFORMATION AND/OR HYPOPLASIA OF ZYGOMATIC BONE AND RELATED DEVICE FOR ZYGOMATIC REGION RELIEF AND VOLUME RESTORATION Russian patent published in 2008 - IPC A61B17/56 A61B17/68 A61B17/80 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, specifically to maxillofacial surgery and can be used for treatment of patients suffering from deformations and-or hypoplasia of zygomatic bone. Mucous membrane and periosteum are dissected by crossover fold of upper jaw on injured side. Zygomatic bone osteotomy is carried out by anrerior wall of maxillary sinus, low orbit edge, orbit bottom closer to its bottom edge in direction zygomaticofrontal process, then it is crossed. Further osteotomy line is continued downwards by external wall of maxillary sinus with zygomaticoalveolar crest bended around from below to meeting with osteotomy starting point. Within osteotomy separate bone bridges between upper jaw and zygomatic bone are left. Used device is applied for zygomatic region relief and volume restoration. Device contains case intercrossed bars, one of which is equipped sliding block longitudinally movable. On the end of sliding block there is additional bar mounted perpendicularly to both bars. Both bars are equipped by stem legs with punched plates. Anterior surface of zygomatic bone is covered with stem punched plate fixed to zygomatic bone, and other stem plate is fixed to alveolar process of upper jaw with traction vector selected. Bone bridges are dissected, malar arch is crossed, zygomatic bone is pressed by osteotomy line during 8-10 days. Further distraction and retention of fragments follow. Method and related device make integrated inventive plan and enables to increase volume of injured area, to move zygomatic bone in three planes restoring facial symmetry.

EFFECT: development of method of elimination of zygomatic bone deformation with zygomatic region relief and volume restoration.
