Deep Neck Space Infections: A Retrospective Analysis and Review A study on Deep Neck space infection in a tertiary care centre

Deep neck space infections (DNIs) are serious and potentially life-threatening conditions characterized by infections in the potential spaces and fascial planes of the neck. A retrospective analysis of 21 patients with DNIs presented to our hospital in 2024 were analyzed, which revealed that submandibular space infection was the most common type, often precipitated by dental infections. Diabetes mellitus was the most prevalent comorbid condition, and Klebsiella pneumoniae was the most frequently isolated organism. Polymicrobial infections were common. The increasing prevalence of resistant bacterial strains and the impact of underlying host immunity and microbial multidrug resistance highlight the need for vigilant surveillance, mandatory susceptibility testing, and tailored antibiotic treatment. Early diagnosis, prompt intervention, and appropriate management are crucial to reduce morbidity and mortality associated with DNIs.
