METHOD OF INFRAORBITAL ANESTHESIA Russian patent published in 2020 - IPC A61M16/00 

FIELD: medicine.

SUBSTANCE: invention refers to dentistry and can be used as an anesthesia technique for blocking peripheral branches of the infraorbital nerve when performing dental surgeries. Method of infraorbital anesthesia is characterized by using a device containing working element 1, which is fitted with base 7 on pull-out rod 9 with handle 10. Working element 1 is made in the form of an inclined housing, which includes in upper part horizontal support 5 and vertical alignment 6 projections, and in lower part base 7 with retainer 8. On the housing there is a longitudinal row of three reference holes 4 at distance below 5, 7.5 and 10 mm from the plane of the horizontal support projection 5, and to the housing are welded on opposite sides of two side guide plates 2, on longitudinal faces of which are selected by three slots 3 of semilunar forms of distance below 10 mm and outside 10 mm from the corresponding orientation holes 4 of housing, for which horizontal support projection 5 of working element 1 is installed on lower edge of eye socket, wherein the vertical alignment projection 6 is placed at the level of the conditional vertical line passing through the eye pupil of the patient looking strictly forward, and lower part of device with handle 10 is located vertically in area of upper second premolar, after which through semilunar slot-landmark 3 of lateral guide plate 2 syringe needle is injected in direction perpendicular to skin until contact with bone tissue, then, without removing, the needle is directed and moved towards the corresponding orientated hole 4 to a depth of up to 15 mm, while performing the hydro-preparation by precondition 0.5 ml of an anesthetic in front of the needle, the rest amount of anesthetic is administered after the negative aspiration test. Use of the present invention provides the conditions for increasing the safety and effectiveness of anesthesia by accurately determining the infraorbital foramen topography, insertion points, direction and depth of needle immersion into area of infraorbital foramen. At that, complex anatomo-topographical landmarks, which are used in the classical method of infraorbital anesthesia, are completely excluded. Such an approach minimizes trauma of the neurovascular bundle in the infraorbital foramen area and improves the quality of dental care.

EFFECT: technical result consists in improvement of accuracy of determination of infraorbital foramen topography, point of prick in, direction and depth of needle immersion when performing infraorbital anesthesia.
