[Topographic-anatomical aspects of nerve-saving operations in the temporal area and in the lateral part of a face].
Bicoronary access is now considered as optimal for performance of operative interventions in the upper part of face. At the same time, this access is associated with the probability of damaging the innervation of the frontal muscles. Thus, the objective of this investigation was to study the individual variability of topography of facial nerve branches in temporal and parotid areas, with specification of projections of temporal branches of a facial nerve to frontal muscle in order to define a safe zone for dissection. The material was obtained from 36 corpses of adult persons, and precision preparation method was used together with the recording and mathematical processing of the results obtained. It was established, that in objects with a size of tragoorbital line less than 8 cm, a single frontal branch of a facial nerve was present, and its safety zone was about 1 cm to the front from tragus auris. In objects with the size of tragoorbital line equal to 8 cm and more, a common trunk of frontal branch of facial nerve was present together with a branch to m. orbicularis oculi, while its safety zone was equal to 1.5 cm and it was located to the front of tragus auris.
