Background: The role of perioperative antibiotics in cleft palate remains a topic of debate. Advocates stress their importance in preventing local and systemic infections and decreasing the incidence of oronasal fistula formation. However, few studies to date have directly evaluated the role of antibiotics and other antimicrobial measures in cleft palate surgery. Objective: The aim of this review is to evaluate the evidence surrounding the use of perioperative antibiotics and other antimicrobial interventions in cleft palate surgery. Additionally, we review the literature on the oral flora unique to the cleft palate patient population. Methods: This was accomplished utilizing PubMed, Medline, and the Cochrane Library with MeSH and generic terms. Articles were selected based on predefined inclusion and exclusion criteria. Results: This review highlights the lack of higher level evidence on perioperative antibiotic use and other antimicrobial interventions in cleft palatoplasty and calls for further research on the matter. Conclusions: The literature appears to support the use of preoperative antibiotics for cleft palatoplasty, but the benefits of prolonged postoperative antibiotic use remain questionable.
