[Diagnostic and treatment of necrotizing cervical fascitis. Clinical course after a Ludwig angina].

The Ludwig angina is an infection of the base of the mouth and submandibular region, frecuently after a dental extraction or a piece in bad state. When it surpassees the milohioid muscle it extends dissecting the superficial aponeurotic planes, and can evolve to a necrotisant fascitis. We present the case of a 67 years old man with a painful tumefaction of the mouth base and submandibular region. The CT reflected an heterogenous submaxilar lesion that extended by the deep cervical fascia introducing itself in the thorax. Under antibiotic treatment the pus was drained by cervicotomy, with daily cures during 3 weeks.
