Abstract
The tongue is highly vascular and receives a bilateral blood supply from the lingual arteries and from the facial, pharyngeal, and palatine arteries. Because of its rich blood supply, necrosis of the tongue is a rare event.1 Even in cases in which bilateral ligation of the external carotid arteries is affected, this complication has not been reported.2,3 Temporal arteritis (TA) seems to be the most frequent cause of tongue necrosis, as first described by Hutchinson in 1890 and then by Horton in 1932.4 Approximately 63 cases have been reported in the literature since 1959.5-7 Necrosis has also been reported subsequent to tongue lesions, tongue carcinoma, abscess of the floor of the mouth, syphilis, and Hodgkin’s disease.8 In this report, we present the case of a patient with bilateral tongue necrosis secondary to ischemia due to cardiac arrest.
