Анатомо-топографическое обоснование мандибулярной анестезии у животных различных таксономических групп

Abstract

This article presents anatomical and topographic substantiation of performing mandibular anesthesia in animals of different taxonomic groups (domestic horse, sheep, dog). Studies were carried out at the Department of Anatomy and Histology of Animals named after Prof. A.F. Klimov of Moscow State Academy of Veterinary Medicine and Biotechnology – MVA by K. I. Skryabin. The object of the study were: domestic horse (Equus caballus) (n=14), sheep (Ovis aries) (n=20), mesocephalic dog (Canis lupus familiaris) (n=20) without pronounced signs of pathology of head organs. The material for the study were mandibles and review radiographs of the head region. We used anatomical dissection, macromorphometry and review radiography with subsequent statistical processing of the obtained digital data. The results of the study revealed species and interspecific regularities and features of anatomical organization of mandibular foramen in different taxonomic groups (domestic horse, sheep, dog). Based on the results of macromorphometry and analysis of anatomical structures and review radiographs, the skeletotopic landmarks of the canal-forming foramen on the mandible were established, which are important to consider when anesthetizing the mandibular branch of the trigeminal nerve. The obtained results are basic in the development of new accesses to the inferior alveolar nerve when performing conduction anesthesia in animal dentistry.
