METHOD FOR LOCALISATION OF NEEDLE INSERTION POINT AND DIRECTION TO STYLOMASTOID FORAMEN IN FACIAL NERVE BLOCK

摘要

FIELD: medicine. ^ SUBSTANCE: treatment of the patients with the facial nerve syndrome involves facial nerve block. A needle is pricked in the vertex of right angle with its one side being a straight line in parallel to the mastoid axis on its anterior surface. The other side is a line drawn along the lower edge of external acoustic meatus. The needle is pushed on towards the stylomastoid foramen that corresponds to a right angle bisector. The depth of needle penetration makes 8-16 mm. ^ EFFECT: method allows for considerably reduced risk of potential damages of significant adjacent anatomic formations, providing thereby adequate anaesthesia of facial nerve. ^ 1 dwg
