Gorbachenko O. Topography, connections and structural organization of vegetative node in adults and elderly people.

Object of the study: Otic vegetative ganglion in people of mature and elderly age. Purpose of the study: To establish individual characteristics of topography, connections and internal structure of the otic vegetative ganglion in people of mature and elderly age. Methods of the study: anthropometric, macromicroscopic, histology study, method of serial semi-thin slices. The obtained digital data were processed using a personal computer with the use of variation statistics, correlation and information analysis. Practical significance: the findings of the research were used in the textbook "Operative surgery and topographic anatomy" for the students of dental faculties of higher medical schools of Ukraine. The data about the characteristics of age-dependent changes of the otic ganglion can be used in the clinic of nervous diseases. Novelty of the obtained results: the performed macroscopic and histological study allowed to establish two extreme forms of the otic ganglion in men depending on the shape of the skull. Characteristic external shape of the ganglion and its branches were revealed. The characteristics of structural organization of the otic ganglion were studied. The organization of microcirculation bed of the otic ganglion in people of mature and elderly age was determined. Basing on the analysis of the digital data, correlation between the size of the otic ganglion and the shape of the skull was determined. Introduction: the data of the research were introduced into the teaching process of operative surgery and topographic anatomy department and department of human anatomy of Ukrainian Medical Dental Academy. Sphere of application: medicine, neurology, dentistry.
