METHOD FOR CLOSING MUCOSAL DEFECT IN CLEFT AREA OF ALVEOLAR PROCESS Russian patent published in 2023 - IPC A61B17/24 A61B17/56 

FIELD: medicine.

SUBSTANCE: invention relates to the field of medicine, namely maxillofacial surgery and surgical dentistry. After infiltration anesthesia and hydrotreating of the mucosa in the area of the defect of the alveolar process of the upper jaw, an incision of the mucosa is made along the edge of the defect throughout its entire length. Further, on the side of the cleft in the defect area, the incision along the edge of the alveolar arch is prolonged. The incision is continued along the contour of the papilla of the milk canine or milk premolar for half or the entire width of the tooth crown. Then the incision of the mucosa to the periosteum is directed upwards at an angle of 90 degrees to the border of the mucous-gingival junction and form the future mucous-periosteal flap in the form of an inverted letter "P". After that, the incision of the mucosa on a small fragment is directed horizontally laterally to the first molar, where it is finished with an obliquely vertical laxative incision up to 1.0 cm in length according to the "poker" type. The opposite side of the alveolar process of the upper jaw is dissected along the papillae in the healthy direction to the canine or first premolar. The muco-periosteal flaps peel off apically from the incision line to the jaw. Next, the resulting mucosa- the periosteal flap is moved by sliding due to a relaxing oblique-vertical incision and the ability of the alveolar mucosa to stretch. Shifting medially to the area of the defect, they are fixed with nodular sutures, covering the neck of the milk canine or premolar, over which the flap was cut. The stitches are removed on the 13th day after the operation.

EFECT: method makes it possible to replenish significant volumes of lost soft tissues when closing a defect in the area of the congenital cleft of the alveolar process, restore the function of the alveolar process without causing deformation of adjacent tissues and donor areas.
