Abstract
Objectives
The examination of the sublingual vein, along with the tongue itself and the tongue's coat, is a very important diagnostic factor. In order to accurately examine the sublingual vein, I intend to understand the meaning by reviewing the Traditional Korean medical literature.
Methods
Relevant literature on sublingual vein examination druing tongue diagnosis was collected, cited, and analyzed.
Result
At first, the sublingual vein was used as an acupuncture point, and it was used to be careful because language disorders may occur if damaged during treatment. After that, in reference to jaundice in 610 AD, the color of the sublingual vein took on diagnostic significance. In China, Western medicine was incorporated in the 1950s, explaining that hypertension or portal hypertension was associated with the color or shape of the sublingual vein. In the 1960s, the length of the sublingual vein was not more than 3/5 of the length at the bottom of the tongue, the diameter of the sublingual vein was not more than 2.7 mm, and the color was said to be a healthy sublingual vein with a dark red. It has since been regarded as a continuous standard. Recently, it has been shown that many vascular diseases, including cardiovascular diseases in Western medicine, are related to sublingual varices.
Conclusion
The sublingual vein, along with the body of the tongue and the coat of the tongue, is an important factor to be examined. For the examination of the sublingual vein, it can be diagnosed as blood stasis by considering important factors such as whether it exceeds 3/5 of the length from the apex of the tongue to the bottom of the tongue, whether the diameter of the sublingual vein exceeds 2.7 mm, and whether the color changes from dark red and has a dark blue color. In the future, it is expected that a more advanced standard for quantification of sublingual veins will be developed in Korea based on this.
