[Anastomoses of the terminal branches of the facial nerve and of the trigeminal nerve].

Study of peripheric anastomoses between facial et trijeminal nerves based on 18 dissections of 13 adults and 5 foetuses. Macroscopic study shows that those anastomoses are similar in all cases on any comparable levels of the face. Semi-macroscopic study on foetuses (coloration by means of gold chlorid) and histological study on anastomoses (by means of longitudinal sections) reveal that either motor and sensitive fibres grow together and join the appropriate muscles, or proprioceptor fibres follow the facial nerve in the opposite direction and then leave it, forming recurrent branches. Cutaneous endings of muscles present a great number of Pacinian corpuscules.
