Classification of arterial forms in the sublingual and submental regions. 1) Facial and lingual arteries branch independently from the external carotid artery. L: There is no communication between submental artery and lingual artery. Sublingual artery branches off lingual artery; LF-1: The profounder branch of the submental artery, which pierces through the mylohyoid muscle, and the sublingual artery, which originated from the lingual artery, form anastomoses in the sublingual space; LF-2: The profounder branch of the submental artery does not anastomose with the sublingual artery, which branched off the lingual artery. Two sublingual arteries form from the submental and lingual arteries, and distribute independently in the sublingual space; F-1: The submental artery and the sublingual artery branched off the facial artery behind the mylohyoid muscle. The sublingual artery has no supply from the lingual artery; F-2: The submental artery and the sublingual artery branched off the facial artery behind the mylohyoid muscle. The profounder branch of the submental artery and the sublingual artery (originating from the facial artery) anastomose; F-3: The profounder branch of the submental artery supplies the sublingual region and becomes the sublingual artery. The sublingual artery has not branched off the lingual artery. 2) The facial artery and the lingual artery form a common trunk. C-1: After the facial artery and the lingual artery branched, no anastomoses formed. The sublingual artery has branched from the lingual artery; C-2: The profounder branch of the submental artery and the sublingual artery, which branched off the lingual artery, anastomose in the sublingual space; C-3: The profounder branch of the submental artery becomes the sublingual artery in the sublingual space. The sublingual artery has not branched off the lingual artery; C-4: The facial artery divided into the submental and the sublingual arteries at the posterior portion of the mylohyoid muscle. The sublingual artery has not branched off the lingual artery.
