Enhanced computed tomography revealed a diffuse abscess spreading to the sublingual, submental, and submandibular spaces. The patient underwent a laryngotracheotomy and cervical drainage because he had laryngeal edema. However, an abscess had formed in the anterior mediastinum through the left intercarotic space, and hydrothorax was found. Then, surgical drainage for the deep cervical abscess and endoscopic transthoracic drainage for the descending necrotizing mediastinitis were performed. The treatment succeeded, and he was discharged.
