Abstract
Background: for optimal functional and aesthetic results of operations on the face of need in-depth knowledge of
sources of the sensory innervation of the tissues of the lips and neighboring regions – labial branches of the mental and infraorbital nerves. The few scientific publications do not give a clear picture of the range of variability of individual features
of the afferent innervation of the lips of the mouth.
Material and methods: the study was carried out on 70 preparations of the soft tissues facial masks of human corpses
by preparation of the mental and infraorbital nerves.
Results: individual features of the mental and infraorbital nerves and their labial branches are appear different but
specific to each age range of the number and thickness of the nerve trunks and the area of distribution. Designated two
forms of the structure of the lower labial branches of the mental nerve: main and disperse with the characteristic features.
Conclusions: the lower and upper labial branches of the mental and infraorbital nerves does not lie on the jaws or
under the skin of the lips, but have complex topographical and anatomical relationships with their tissues. From the motor
branches of the facial nerve are different by radial direction, flat and spiral shape of the trunks. The highest concentration
of the nerve trunks is observed in the middle third of the each lip and in the skin of the intermediate part (“red border”).
