MORPHOLOGY AND INCIDENCE OF VALVES IN THE FACIAL VEIN OF HUMANS
This study was carried out to determine the number of venous valves of the facial vein. Left and right veins from 50 adult male corpses previously maintained in formaldehyde were dissected and analyzed microscopically as well as under a stereomicroscope. Valves were found in 41 cases (82%). They wer...

| Sumario: | This study was carried out to determine the number of venous valves of the facial vein. Left and right veins from 50 adult male corpses previously maintained in formaldehyde were dissected and analyzed microscopically as well as under a stereomicroscope. Valves were found in 41 cases (82%). They were well developed and were classified as ostial and parietal. The ostial valves were unicuspid or bicuspid. The parietal valves were bicuspid. The facial vein segment with the largest number of venous valves was located at the submandibular gland level. A valval sinus was found on the venous walls with valves. The relations among anatomical variations, nature of the venous wall and presence of valves are discussed |
