The ultrasonographic features and intranodal vascular patterns of the submandibular glands were evaluated to establish criteria for the diagnosis of salivary glands. There were significant differences between the internal echo of the submandibular glands and the parotid glands and the tongue. The internal echo of the submandibular gland indicated the lowest intensity. The internal echo intensity in the under 30% weight/height ratio group was hypoechoic, and the echo intensity in the over 50% weight/height ratio group was hyperechoic. The ratio of the obvious posterior echo of the submandibular glands were 11.0-15.0%. The ratio of the obvious boundary echo of the submandibular glands were 2.5-3.6%. No lateral shadow was observed. Continuity of the bifurcation part with the trunk was observed in 17 facial arteries (68%), 14 submental arteries (56%), and these arteries were easily examnined. Continuity was observed in 1 branch of the external carotid artery (4%), and the suprahyoid branch of the lingual artery was not observed.
