METHOD FOR SURGICAL MANAGEMENT OF LIQUORRHEA NASALIS Russian patent published in 2014 - IPC A61B17/00 A61B1/313 

FIELD: medicine.

SUBSTANCE: defect of an olfactory fissure is repaired from an endoscopic intracranial minimally invasive approach to the olfactory fissure that is provided by incising along a skin fold in a projection of an inferomedial frontal lobe depending on the patient's characteristics. The mucosa is removed from a frontal sinus through a frontal sinus orifice of an anterior wall. A fragment of a posterior wall of the frontal sinus in a paramedian direction in a basal frontal sinus to form a duplication. A dura mater is stripped from the olfactory fissure, and an autogenous bone is laid into a bone bed of the olfactory fissure shaped thereafter. The autogenous bone is covered with an Indost plate and the dura mater duplication separated earlier; the repair region is sealed with Tissucol-KIT fibrin two-pack glue that is followed by the plastic repair of the posterior and anterior walls of the frontal sinus.

EFFECT: method enables providing higher clinical effectiveness ensured by using the minimally invasive transcranial approaches to a base of the cranial fossa.
