Abstract
Background: Maxillofacial infections (MIs), particularly surgical site infections (SSIs) following orthognathic surgery, represent a significant clinical concern due to their potential severity and impact on treatment outcomes. Although antibiotic prophylaxis is standard practice, growing bacterial resistance-especially in penicillin-allergic patients-challenges the effectiveness of alternative regimens such as clindamycin.
Material and methods: This retrospective study analyzed 100 consecutive patients who underwent orthognathic surgery between 2022 and 2023, performed by the same surgical team. All patients received standardized perioperative care, including hospitalization and intravenous (IV) antibiotic prophylaxis with cefazolin or clindamycin for those allergic to penicillin. The incidence of SSIs was evaluated and correlated with the type of antibiotic used. Microbial cultures and antibiograms were obtained from infected cases requiring surgical wound revision.
Results: Of the 100 patients, 98 received prophylactic cefazolin and showed no SSIs. The remaining 2 patients, both allergic to penicillin and treated with IV clindamycin, developed SSIs within the first postoperative week. Both cases required surgical drainage, hospitalization, and culture-based antibiotic therapy. Pathogens isolated included Streptococcus mitis, S. oralis, S. constellatus, and Haemophilus parainfluenzae, all resistant to clindamycin and erythromycin but sensitive to beta-lactams and fluoroquinolones. Both patients responded favorably to ciprofloxacin and metronidazole.
Conclusions: This study highlights a significant risk of infection associated with clindamycin prophylaxis in penicillin-allergic patients undergoing orthognathic surgery. Cefazolin proved effective in preventing SSIs. These findings underscore the urgent need for updated, evidence-based prophylactic protocols in maxillofacial surgery, particularly for patients with beta-lactam allergies.
