Introduction: Delta neutrophil index (DNI) is used as a useful indicator in the diagnosis of infections and sepsis, but there is no study yet to evaluate DNA as an inflammatory indicator in deep neck infections. Our goal is to determine the effectiveness of DNA as a early predictive indicator in distinguishing apse and flegmonus in patients with deep neck infection (DNE). Materials and methods: A total of 43 patients with DNE were divided into two groups (apse (N:23) and flegmon (N:20)) according to the presence of post-drenage pimples. The group’s hospitalization time (LOS) and laboratory parameters; the number of leukocytes (WBC), neutrophils (NEU), lymphocytes (LYM), the neutrophil-lenphocytes rate (NLR), the delta neutrophil index (DNI), procalcitonin (PCT), C-reactive protein (CRP), erythrosite sedimentation rate (ESR) were compared. The findings: DNI and LOS were significantly high in the group of apse (p<0,05). Other inflammatory indicators (CRP, PCT, ESR) were higher than flegmonds in the abse group, but the difference between these values was not statistically meaningful (p>0,05). The optimal marginal value of the DNI to predict the existence of Apse was 0.95%. The sensitivity and personality of the DNA was respectively 60.9% and 75%. The result: DNA appears as an effective parameter in determining the presence of apse in patients with deep neck infection and assessing the prognosis of the disease. DNI can help clinical diagnosis with acceptable sensitivity and personality in the process of distinguishing apse and flegmon in patients with deep neck infection and making a decision on surgery.
