Abstract

Purpose: A retrospective 17-year review of the epidemiology, microbiological aspects, and treatment of patients hospitalized for non-odontogenic maxillofacial infections.

Methods: A retrospective study reviewed 4040 medical records of patients hospitalized at Vilnius University Hospital Zalgiris Clinic during the period of 2003 to 2019. The following data were collected: patient sociodemographic characteristics, length of hospitalization, sources of infection, affected anatomical regions, treatment modalities, microbiological findings, and sensitivity to antibiotics.

Results: The mean (sd) annual incidence of non-odontogenic maxillofacial infections over the past 17 years was 237 (49) cases, and the mean (sd) hospital stay was 7.3 (4.5) days. The male-to-female ratio was 1.9:1, while the mean (sd) patient age was 42.1 (19.0) years. The need for an additional incision and the involvement of multiple anatomical regions were the strongest predictors of longer hospitalization. A total of 139 microorganism species were identified, with Bacteroides, Prevotella, and Staphylococcus showing the highest resistance to penicillin.

Conclusions: Longer hospital stays were associated with older age (≥ 65 years), smoking, systemic diseases, type of treatment, involvement of multiple anatomical regions, and the need for additional surgery. Most of the cultured microorganisms were Staphylococcus species.
