    Deep neck mediastinitis (DNM) remains a serious threat, often stemming from dental infections. Early diagnosis via CT scans and physician suspicion, coupled with aggressive treatment, is crucial to reduce its high mortality rate.

    Area of Science:

    • Medicine
    • Infectious Diseases
    • Otolaryngology

    Background:

    • Mediastinitis complicating oropharyngeal infections, termed deep neck mediastinitis (DNM), presents a significant clinical challenge.
    • Despite the antibiotic era, DNM incidence has declined but its severe morbidity and mortality persist.

    Purpose of the Study:

    • To analyze the characteristics, diagnosis, and management of deep neck mediastinitis (DNM).
    • To highlight factors contributing to high mortality and emphasize optimal diagnostic and treatment strategies.

    Main Methods:

    • Retrospective review of institutional cases (1975-1981) and literature review (1960-1980).
    • Analysis of underlying infections, bacteriology, diagnostic tools, and treatment outcomes.
    • Emphasis on computed tomography (CT) scan utility and clinical suspicion.

    Main Results:

    • Odontogenic infections, particularly mandibular molars, were the predominant source.
    • DNM is typically a polymicrobial process with a significant role for anaerobes.
    • A high mortality rate of approximately 42% persists, linked to delayed diagnosis and inadequate drainage.

    Conclusions:

    • Early diagnosis of DNM is critical, with CT scans and physician vigilance being paramount.
    • Aggressive combined medical and surgical management, informed by anatomical knowledge, is essential to improve outcomes.
    • Despite advances, DNM remains a life-threatening condition requiring prompt and comprehensive intervention.
