Treatment of Acute Mediastinitis with Fever in Descending Necrotizing Mediastinitis from a Head and Neck Source
Descending necrotizing mediastinitis (DNM) is a severe form of acute mediastinitis in which infection originating from an oropharyngeal or odontogenic focus spreads through the neck's fascial planes and descends into the mediastinum. Fever is a consistent presenting feature alongside the characteristic neck and chest involvement.
Clinical Scenario
The infection originates from a head and neck source — most commonly an oropharyngeal or odontogenic (dental) focus — and propagates downward through fascial spaces into the mediastinum. Patients typically present with signs of the primary oropharyngeal or dental infection together with fever.
Fever
Oropharyngeal / odontogenic source
Neck & chest pain
Dyspnoea
Treatment Approach — Partial Overview
Management requires immediate intravenous broad-spectrum antibiotics covering both aerobic and anaerobic bacteria, alongside surgical source control and mediastinal drainage. The full structured protocol — including specific interventions, their indications, sequencing, and ICU criteria — is available via the link below.

- Descending necrotizing mediastinitis describes an infection with its origin from a head and neck source, most commonly an oropharyngeal or odontogenic focus, which then spreads in the fascial spaces of the head and neck and descends downward into the mediastinum.
- Patients usually have experienced and present with symptoms and signs of an oropharyngeal/odontogenic infection and fever.
- Neck and chest pain together with dyspnoea are other potential findings.
- Administration of IV broad-spectrum antibiotics with coverage for aerobic and anaerobic bacteria as soon as possible is mandatory considering the high mortality rates of up to 85% in the preantibiotic era.
- In case of severe sepsis and/or septic shock, early ICU admission for optimal management is strongly advisable.
