Analysis of Clinical Symptoms and Biochemical Parameters in Odontogenic Cellulitis of the Head and Neck Region in Children

Many cases of cellulitis in the head and neck region among hospitalized pediatric patients are related to odontogenic infections. C-reactive protein (CRP), white blood cell (WBC) count, neutrophils to lymphocytes ratio (NLR), D-dimer, and prealbumin can be used to assess the severity of odontogenic inflammation. The aim of the study is to evaluate the biochemical parameters as a predictor factor of the severity of odontogenic cellulitis in children. This study was conducted from 2020 to 2021 on patients admitted to the Department of Pediatric Otolaryngology and Pediatric Head and Neck Surgery of the Upper Silesian Children's Health Center in Katowice. We included 40 patients aged 2-16 in the study, who were divided into two groups: research (SS-Study subject) (n = 20) and control (CS-Control subject) (n = 20). The patients underwent an interview and physical examination to assess the presence of intraoral and extraoral swelling and the presence of trismus. The patients who qualified for the study had blood taken to determine the level of CRP, WBCs, NLR, D-dimers, and prealbumin. Differences in biochemical test results in the SS and CS were statistically significant (p < 0.05). In the SS group, the mean values of biochemical parameters exceeded the clinical norm. A statistically significant positive relationship was found between CRP and extraoral swelling. The NLR correlates significantly with extraoral swelling and the length of hospitalization. D-dimer statistically correlated with trismus, extraoral swelling, and the number of anatomical spaces involved. The NLR and CRP ratio can be considered a prognostic marker of the course of infection and hospitalization time.
