    Purpose

    Retro- and parapharyngeal abscess are potentially life-threatening complications of upper airway infection. The aim of our retrospective monocentric cohort study was to identify predictors of clinical course, management and outcome of retro- and parapharyngeal abscess (RPA/PPA) in adults and children.

    Patients and methods

    Retrospective analysis of the patient data treated for RPA/PPA between 2009-2020 at the Department of Otorhinolaryngology-Head and Neck Surgery, University of Freiburg (100 adults, 16 children). Influence of sex, age, symptoms, laboratory findings and identified pathogens as well as comorbidities, treatment, complications and duration of hospitalisation were analysed.

    Results

    Adults had more comorbidites than children (43% vs. 25%). Leading symptoms were dys-/aphagia (adults), while in children leading symptoms (torticollis) were less present. CrP values at admission were larger for adults (p<0.001). Most frequent pathogens identified were streptococcus spp. and anaerobic bacteria. Adults had also a higher complication rate than children (26% vs. 12.2%), risk of postoperative bleeding was more present in children (p=0.008). With increased abscess size, more surgical interventions were necessary, and a tracheotomy was more frequently needed. Lower normalized Hb value (p<0.001), but not CrP, at admission was associated with increased duration of hospitalization.

    Conclusion

    Our results showed lower normalized Hb value at admission to be a predictive biomarkers for increased duration of hospitalization. The potential use of this biomarker as a screening tool needs to be prospectively evaluated.
