A morphological study on human lingual venous valves.

This study deals with the appearance, function and pathophysiological action of the lingual venous valve in the design of surgical tongue flaps and in analyzing inspection of the tongue. Thirty two adult cadavers were studied, of which 7 were corrosive cast specimens. The lingual v. is well supplied with venous valves which may be divided into 3 types morphologically: hemispherical, spherical, and hanging spherical. Venous valves are classified according to their structures: bivalves, monovalves, and venous cristae. The abundant venous valves of the tongue effectively prevent reflux of blood. Various factors that influence venous blood reflux in the head and neck can be observed, analysed and judged by inspection of the tongue; the design of the pedicle and the anastomotic position of tongue flap should comply with the positions and orientations of its venous valves.

Anatomic bases of tongue flaps.

The morphological structure of the lingual a. was studied in 50 dissected and 14 vascular cast specimens. The course of this artery is divided into 4 segments: the original segment, the segment within hyoglossus, the ascending and the horizontal segments of the deep lingual a. The root of the tongue is supplied by 2 to 3 root branches of the lingual a., the ascending palatine a. and the tonsillar a. The body of the tongue is nourished on averaged by 25 arterial branches from the deep lingual a. The ventral surface of the tongue, as well as the sublingual gland and the floor of the mouth, is supplied by the sublingual a. The termination of the lingual a. The termination of the lingual a. anastomoses with the submental branch of the facial a. to form the lingual frenal a. Except for a submucous arterial network on the dorsum of the tongue, all blood vessels are separated completely by the lingual septum, through which arterial anastomoses (2.0 mm in diameter) can be found occasionally.

Morphologic studies of the venous drainage of the tongue.

The aim of this work was to study the role of the venous drainage of the tongue in tongue inspection in traditional Chinese medicine and tongue-flap surgery. Thirty-two adult cadavers were observed, including 7 venous corrosivecast specimens. The decreasing order of venous drainage of the tongue, based on the diameter of the vein and size of its drainage area, was the accompanying v. of the hypoglossal n., the epiglottic valleculate v., the accompanying v. of the lingual n., the lingual root v. and the accompanying v. of the lingual a. The veins constituting the picture of the tongue seen in sublingual collateral inspection were the companion vv. of the hypoglossal and lingual nn. The pedicle of a tongue flap must maintain efficient venous drainage canal.
