[Lipid analysis in jaw cysts]

In patients with jaw cysts, cyst content and blood serum are examined by means of thin section chromatography with regard to their contents of cholesterol, free fatty acids, triglycerides and cholesterol esters. The increase in lipid content found in the cyst is primarily due to the increase in free cholesterol. Since the serum values are within normal ranges, it is unlikely that cysts are the result of endogenous causes. Our examinations showed that they are primarily due to local processes.
