METHOD OF FORMING A MUCOSAL FLAP WITH SURGICAL APPROACH TO THE MAXILLARY SINUS THROUGH A LOWER NASAL PASSAGE Russian patent published in 2020 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to rhinosinusosurgery, and can be used in surgical intervention on maxillary sinuses. Infiltration anesthesia and medialization of the inferior nasal concha is performed. In infiltration anesthesia, the injection is performed under the mucous membrane in the agger nasi area, in the bottom and lateral wall of the nasal cavity under the inferior nasal concha. A U-shaped incision is made: vertical lines of the incision are made at the level of the anterior end of the inferior nasal concha and at the posterior edge of the canopy of the lower nasal passage; a horizontal incision is made from behind in front of the bottom of the nose and the lower borders of the vertical incisions are joined to form a U-shaped flap.
