However, evidence supporting their use in preventing postoperative infectious complications is limited. The aim of this study is to assess the efficacy of preoperative antiseptic techniques in reducing postoperative infectious complications within 30 days of surgery.<\/jats:p>\n                  <jats:p>A multicenter, prospective, randomized, single-blind, three-arm trial was conducted from February 2019 to October 2021. Participants were randomized to either of three antiseptic preparation techniques: external 0.9% NaCl nasal preparation, external 0.05% chlorhexidine gluconate, or intranasal irrigation with 80\u2009mg of gentamicin added to 1,000\u2009mL of 0.9% NaCl plus external nasal preparation with chlorhexidine gluconate 0.05%. A total of 130 adults with skull base pathologies were randomized; 12 were excluded before randomization for failure to meet the inclusion criteria (n\u2009=\u20099) or refusal to participate (n\u2009=\u20093).
