Using a pachymeter with 0,02mm of accuracy the distances were measured taking as a reference the origin of the lingual artery related to the the facial artery, the superior thyroid artery and with the bifurcation of the common carotid artery (Fig.
Concerning about the lingual artery it was observed that in 25% of the cases were found the presence of the linguofacial trunk (Fig.
The morphometric data found among the distances of the origins of the arteries showed the following values: the maximum distance between the origins of the lingual and facial arteries on the right side was 14,56 mm, and on the left side was 11,76 mm, the minimum distance was zero, what showed the presence of the linguofacial trunk in both sides; the maximum distance between the origins of the lingual and superior thyroid arteries was 39,04mm on the left side and the minimum distance was found on the right side 3,72 mm; concerning about the distance between the origin of the lingual artery and the bifurcation of the common carotid artery on the right side was found a maximum length of 37,42 mm and on the left side was found the minimum of 5,32 mm.
2) Preservation of just one of the lingual arteries is sufficient to maintain adequate tongue vascularity from crossover perfusion by the contralateral lingual artery.
Maloney et al showed that in dogs, the contralateral lingual artery supplied the ligated side 71% of the time, despite the lack of apparent crossover before ligation, as measured by dye distribution.
Following embolization of numerous branches of the right lingual artery and the right internal maxillary artery, a left common carotid arteriogram was obtained.
The left lingual artery was selectively catheterized.
We treated the patient with emergent coil embolization of the left lingual artery, which resulted in immediate hemostasis.
Angiography with oropharyngeal contrast extravasation revealed that the left lingual artery was disrupted (figure 1).
