Question

A patient with an odontogenic deep-neck infection deteriorates despite antibiotics. CT shows gas-containing collections tracking below the carina into both pleural spaces. What is the definitive management priority?

Accepted Answer

Combined cervical and mediastinal drainage plus broad-spectrum intravenous antibiotics

Answer

Continue antibiotics alone for 72 hours because surgery increases dissemination through fascial planes

Answer

High-dose corticosteroids before drainage to reduce mediastinal oedema

Answer

Anticoagulation alone because septic thrombophlebitis is the usual cause of mediastinal gas

Answer

Needle aspiration of the dental socket only because the mediastinal collections are reactive
