Introduction. Branching of the trigeminal nerve on the face has individual anatomical variability. Individual variability of innervation in the soft tissues of the maxillofacial area should be taken into account during their local anesthesia. The purpose of the study was to develop a method of conductive anesthesia of the zygomaticofacial nerve, taking into account its individual topographic and anatomical features, and to evaluate its clinical effectiveness. Materials and methods. Craniometric studies were performed on 32 natural skulls of corpses of various ages, and 60 images of head section of patients were done in a 3D reconstruction by a multi-detector row spiral computer tomographer. A new method of conductive anesthesia of the zygomaticofacial nerve was applied on 30 stationary patients, comparing its effectiveness with that of a known method. Results and discussion. Based on the results of craniometric studies, as well as on the individual topographic and anatomical features of zygomaticofacial nerve branching in people with different types of skull structure, the technique of conductive anesthesia of the branches of the zygomaticofacial nerve was developed. Conclusions. Application, under clinical conditions, of the technique of conductive anesthesia of the zygomaticofacial nerve, developed by us, in combination with the classical method of local anesthesia of the buccal nerve provides painless surgical interventions on the lateral area of the face.
