Methods: This was a cross-sectional hospital-based study that included patients with pyogenic orofacial space infections. Data on the demographic pattern of the patients, clinical presentations of the disease, and results of culture and sensitivity tests were collected. For analysis, when more than two spaces were involved, the case was classified as multiple space infection. The number of microbial isolates was grouped into no isolate, monomicrobial, and polymicrobial. The significance level was set at p <0.05.
Results: The study consisted of 60 patients of whom 51.7% were males. The mean age was 33 ± 17.3 years. A painful swelling was the chief complaint of the majority of patients. Odontogenic causes of fascial space infection accounted for the majority (81.7%) of the cases. In most (66.7%) patients, multiple fascial spaces were involved, and the submandibular space was the frequently affected space. The most frequently isolated microbes were Streptococcus viridans and coagulase-negative Staphylococcus. The drug susceptibility test of different isolates to antibiotic agents revealed that clindamycin and amoxicillin + clavulanate were effective against both aerobes and anaerobes.
Conclusions: The young individuals and males were more affected. Most of the fascial space infections affect multiple spaces, commonly submandibular space. Streptococcus viridans and coagulase-negative Staphylococcus have frequently encountered isolates. Clindamycin was the most effective drug with a wide spectrum of activity against both aerobes and anaerobes.
