Three cases of trophic disorder in the area of ramifications of the supraorbital nerve

It has long been known that the trigeminal nerve (n. trigeminus) contains motor and sensory fibers, running in separate or mixed branches. The significance of this nerve in the nutrition of the skin, muscles and bones of the face, as well as teeth, has been established not so much experimentally as by clinical observations on patients and is usually noted in large manuals on the physiology or pathology of the nervous system. Clinical studies and observations make it probable that there are separate fibers for each kind of sensation—pain, tactile, thermal. It is natural to assume that trophic impulses also have their own special paths, but how can this be proven? Obviously, too, a thorough examination of the respective patients.
