METHOD FOR IMPROVING VISUALIZATION OF A SURGICAL FIELD DURING ENDOSCOPIC ENDONASAL SURGERY IN PATIENTS WITH POLYPOUS RHINOSINUSITIS Russian patent published in 2019 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely endoscopic endonasal surgery, and can be used to visualize a surgical field during endoscopic endonasal surgery in patients with polypous rhinosinusitis. During the operation in case of bleeding and reduced visualization of the surgical site at least 8 on the Wormald scale, a wedge-palatal artery and/or its branches are coagulated ipsilateral to the side with increased haemorrhage. For this purpose, the mucoperiost is separately separated under the control of the endoscope after the posterior wall of the maxillary sinus is visualized by the raspinator in the projection of the ascending process of the palatine bone towards the anterior wall of the sphenoid sinus. What is found is a wedge-and-palate opening and a wedge-palatal artery/branches of the wedge-palatine artery exiting/leaving it and performing its/their coagulation. After achieving haemostasis, the visualization level of the surgical field is evaluated. When visualization is improved, the separated muckoperiost is laid back and endoscopic endonasal polysynusotomy is continued.

EFFECT: method enables achieving clinically significant improvement of surgical field visualization during endoscopic endonasal surgery in patients with polypous rhinosinusitis, does not increase operative injuries as a whole by preserving vascularization of mucous membrane by branches of mesenteric arteries and facial artery.
