In this study, 15 mature, New Zealand rabbits were used. NaCI solution (0.009) was injected into the common carotid artery to remove the blood from the arteries and veins. Ten rabbits were injected with "blue latex" and 5 rabbits with blue Batson's No 17. The blue Batson's No 17 anatomical corrosion compounds injected rabbits were placed in 33% potassium hydroxide solution for 48 hours to macerate the tissue and to obtain corrosions casts. The rabbits those were injected with latex were kept for 24 hours and placed in 10% formaldehyde and than dissected. The diameters and thicknesses of the veins which formed linguofacial vein were measured by using a digital dial caliper.
The results of this study shown that linguofacial vein was formed with the connection of supraorbital vein, angularis oculi vein, dorsal nasal vein, lateral nasal vein, inferior palpebral vein, superior labial vein, deep facial vein, inferior labial vein, sublingual vein, lingual vein, glandular veins and submental vein. In rabbits the supraorbital vein begins from ophthalmic plexus and continues on the basis of the rostral supraorbital notch (incisura supraorbitals rostralis) in rostroventral direction as angular oculi vein. This differs from mammals, in addition, a branch of deep facial vein connects with thin branches which comes from m. buccinator and glandula buccalis and connects with facial vein before the deep facial vein.
Lingual vein comes from both side and forms an arch on the basis of frenulum linguae by exdending arms at the rostral basihyoid. One arm from this arch extends to the tongue. Thin branches also extends to caudal connecting with the veins of larynx. A vein from arcus hyoideus extends to lingual vein before it connects with linguofacial vein. This vein connects with the branches from ptrygoid plexus and m. masseter.
It was seen that 44% of venous blood which flows in linguofacial vein comes from lingual vein and 56% of it from facial vein. Angularis oculi vein, dorsal nasal vein, lateral nasal vein, superior labial vein, deep facial vein, inferior labial vein make edition to facial vein in the ratio of 16, 18, 13, 14, 24 and 15%, respectively.
