MOLINARI, Sonia Lucy; DE MIRANDA NETO, Marcílio Hubner; CHOPARD, Renato Paulo  and  ALFONSO DIDIO, Liberato João. MESO AND MICROSCOPIC STUDY OF THE FACIAL VEIN  AND ADJACENT TISSUES. Rev. chil. anat. [online]. 1999, vol.17, n.1, pp.33-37. ISSN 0716-9868.  http://dx.doi.org/10.4067/S0716-98681999000100005.

SUMMARY: We carried out this research with the purpose of studying the relations of the facial vein with adjacent structures. The right and left facial veins of 50 corpses were dissected under stereomicroscope and their relations to the neighbour structures were described. Segments of facial veins of 10 corpses were subjected to histological sections stained by the method of Weigert modified by van Gieson. The facial vein, in spite of its short course, undergoes major changes on its wall composition. It is also diversified in its relations of syntopy, relating to muscles, adipose tissue and glands, in addition to other tissues. We verified the presence of elastic and collagen fibers connecting the adventitia to the adjacent tissues, as well as forming a fibrous sheath around the facial vein, which most probably protects this vein against strains produced during the motion of the neighbouring structures. In this work it is also discussed the implications of the syntopy of the facial vein and the biodynamic requirements elicited by motion on the morphology and functioning of this vein.

Keywords : Collagen fiber; Elastic fiber; Facial vein; Functional anatomy.
