Extremely severe infection of the floor of the mouth caused by bacteria present in the mouth and pharynx (oropharynx).
In most cases, the origin of the infection is dental.
The most common symptoms include fever, pain when swallowing, drooling, swelling of the neck, neck pain, redness of the neck and difficulty breathing.
The suspected diagnosis is clinical, reached through questioning and a physical examination; it is confirmed by a CT-scan.
Antibiotic treatment must be started early. It is very important to monitor the airways, which could become occluded due to inflammation.
It generally requires being admitted to the ICU for treatment and control of the possible complications.
