Evaluating the efficacy of single-shot versus prolonged antibiotic prophylaxis in alveolar cleft osteoplasty – A retrospective cohort study

Abstract

This retrospective cohort study aimed to compare the outcomes of alveolar cleft osteoplasty using single-shot antibiotic prophylaxis versus a prolonged antibiotic regimen. The primary endpoints assessed were the incidence of infection, failure of surgical correction, and antibiotic-related side effects. Patients with orofacial clefts affecting the alveolar ridge who underwent alveolar cleft osteoplasty at a tertiary care center between 2015 and 2021 were included. The prolonged antibiotic group received extended antibiotic treatment, while the single-shot group received preoperative antibiotics only. Among 83 patients (mean age 12.8 years), 51 interventions were performed under prolonged antibiotic prophylaxis (mean duration 5.82 days) whereas in 40 interventions only single-shot prophylaxis was administered. There were no significant differences in infection frequency, surgical correction failure, implant loss, or adverse events between the groups. However, after single-shot antibiotic regimen, patients had significantly shorter hospital stays, being discharged on average one day earlier. The study suggests that single-shot antibiotic prophylaxis does not have drawbacks compared to prolonged antibiotic treatment in alveolar cleft osteoplasty. Considering increasing antibiotic resistance and potential side effects, omitting prolonged antibiotic prophylaxis is recommended for patients undergoing alveolar cleft osteoplasty.
