METHOD FOR PREVENTION OF RECURRENT OROANTRAL COMMUNICATIONS Russian patent published in 2014 - IPC A61B17/24 A61K33/18 A61P31/02 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to surgical dentistry and maxillofacial surgery, and is applicable in maxillary sinusotomy with fistula repair. A mucous membrane is incised to a bone under an intubation narcosis after a two-fold preparation of a surgical area. A D-shaped flap is cut out within an alveolar socket of an extracted tooth to be extended along a mucobuccal fold of an upper jaw on one side to a second incisor, and on the other side - to a third molar. The flap together with the periosteum is separated and retracted upwards with exposing a canine fossa and the alveolar socket of the extracted tooth. A hole is created within the canine fossa. Pathologically changed tissues or all sinus mucosa is scooped with a bone curette through the created hole. The alveolar socket of the extracted tooth is inspected. After the cavity has been scooped, an artificial hole is created towards a nasal cavity through an inferior nasal meatus. The sinus cavity is packed with a iodoform cotton swab; an end of the cotton swab is laid thoroughly on a sinus bottom, namely within the defect; the end of the cotton swab is brought out into a nose. A mucoperiosteal flap is mobilised within the alveolar socket of the extracted tooth, laid on the alveolar socket; the wound is closed completely. In the postoperative period, the cotton swab is removed from the sinus on the 9-10^th day. The sutures are removed on the 10-11^th day.

EFFECT: method enables reducing an incidence of recurrent oroantral communications in the postoperative period ensured by a compact packing of the sinus, and the antiseptic and regeneration effect of iodoform on the maxillary sinus.
