METHOD FOR PREVENTION OF POSTOPERATIVE STENOSIS OF SPHENOIDAL SINUS IN SURGICAL TREATMENT OF SPHENOIDITIS Russian patent published in 2020 - IPC A61B17/24 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to otorhinolaryngology, and can be used for prevention of cicatricial stenosis of sphenoid sinus anastomosis after surgical treatment of sinuses of various aetiology. Visual imaging of sphenoid sinus. Vertical incision of the mucous membrane of the anterior wall of the sphenoid sinus is performed from the side of the nasal cavity along the inner edge of the anastomosis, the second is parallel to the first one at the point of the front wall transition into the nasal septum; their upper edges are connected by a horizontal incision. Mucosa of the anterior wall is separated with the help of a raspatory, and the obtained U-shaped flap is turned into the lumen of the choana. Ostrich is widened by a bone expander with preservation of a mucous membrane of anterior wall of a cavity of a sphenoid sinus. Sickle-shaped knife is incision of preserved mucous membrane of anterior wall of sphenoid sinus cavity along edge of newly formed bone window, so that obtained U-shaped flap overlaps inner edge of formed anastomosis. All lumen of sphenoid sinus is visualized, surgical intervention is performed. Sinus is washed with antiseptic solution and antimicrobial preparations. Formed first U-shaped flap is wrapped on lower edge of formed anastomosis, performing tamponade with haemostatic sponge formed anastomosis for fixation of flaps and sphenoethmoidal space, tamponade is removed from nasal cavity on third or fourth day.

EFFECT: method enables reducing the recurrence rate of the disease by preserving the specificity of the mucociliary transport of the sphenoid bone.
