METHOD FOR PREVENTION OF PERFORATED MAXILLARY SINUS MUCOSA IN SINUS LIFTING SURGERY Russian patent published in 2014 - IPC A61B17/24 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to dentistry, and aims at the prevention of the perforated maxillary sinus mucosa in the sinus lifting surgery. An incision is performed under local anaesthesia along the maxillary ridge bone. A mucoperiosteal graft is separated, and an anterolateral wall of the maxillary sinus is skeletonised. An autogenous bone is sampled from the zygomaticoalveolar ridge and an anteriolateral wall of the sinus. A flexible endotracheal tube with an inflated cuff is inserted into the middle nasal passage, wherein air in injected to provide obturation of an opening between the nasal cavity and the sinus. The bone fragment is gently displaced upwards together with the maxillary sinus, and an autoplasma membrane is fixed thereto. After the osteoplastic material and implants are inserted, the defect area of the anterolateral wall of the maxillary sinus is covered with the platelet-rich autoplasma membrane. The mucoperiosteal graft is placed back, and the wound is closed. The stitches are taken out on the 7-8^th day.

EFFECT: by obturation the opening between the nasal cavity and the sinus, the method provides preventing the perforated maxillary sinus mucosa in the sinus lifting surgery.
