METHOD FOR MANDIBULAR AUTOPLASTY Russian patent published in 2006 - IPC A61B17/56 

FIELD: medicine, traumatology, orthopedics.

SUBSTANCE: the present innovation deals with forming a complete complex of new mandibula. It is necessary to take autotransplants out of VIII and IX ribs at the whole length together with periosteum, dissect posterior articular ends, make two transverse grooves at internal concave surface of the longest and widest rib in the middle; the rib should be applied into hot physiological solution and gradually bent to obtain horseshoe-shaped form to be then tightened with bandages to keep the achieved position. One should introduce the ends of autotransplants with costal caputs into formed terminal grooves by developing "articular branch" of new mandibula, to the front it is necessary to introduce the end of another short autotransplant as mandibular "coronary branch" into the groove developed, the ends of horizontal horseshoe-shaped and vertical short autotransplants should be connected with Dacron belt applied perosseously. Between two vertical autotransplants one should apply additional shorter autotransplant with a foramen in the center as a thrust. Through this foramen Dacron belt should be applied, with the ends of this belt it is necessary to capture vertical autotransplants and tighten a knot at internal surface to fix the position achieved. Connection sites of horizontal and vertical autotransplants should be covered with autotransplants' shifted periosteal edges to be sutured with catgut ligatures, from the top it should be covered with fascial fragments of neighboring muscles, and outside it is necessary to develop netting out of absorbable synthetic ligatures along with fixing connection sites of autotransplants. The upper ends of posterior vertical autotransplants should be introduced into temporal articular cavities to be then adapted and fixed with Dacron belt that covers caput's cervix outside and intersects at internal cervical surface. The ends of Dacron belt should be applied at the front and at the rear perosseously through cavitary edges to be tightened together. To the top of "coronary" autotransplant one should suture up inferior end of temporal muscle with perosseous sutures. To "new" mandibula one should suture up buccal, masseter, mylohyoid muscles and, also, mucous membrane of oral cavity from both sides. The innovation provides the development of complete complex of new mandibula with autotransplants at reconstructing oral cavity, mastication, speech and facial shape along with patient's rehabilitation.

EFFECT: higher efficiency of autoplasty.
