Efficacy of autogenous bone grafts preserved in 80% ethanol solution for preventing surgical site infection after cranioplasty: A retrospective cohort study

Surgical site infection (SSI) is common following cranioplasty after decompressive craniectomy (DC). The aim of this study was to assess the risk SSI in terms preservation method autogenous bone graft (ABG), comparing 80% ethanol versus standard subcutaneous ABG preservation. patients who underwent using ABGs DC between 2008 and 2019 were retrospectively reviewed. SSIs compared whose preserved (group A) those subcutaneously B) inverse probability treatment weighting (IPTW) based on propensity scores balance measurable confounders including elderly age, sex, expanded polytetrafluoroethylene, stroke, interval cranioplasty, diabetes mellitus. Total number 127 consisted 56 group A 71 B. occurred five each groups B (8.9% vs. 7%, p = 0.748). IPTW analysis demonstrated that associated with a lower (odds ratio: 0.239, 95％ confidence interval: 0.0615–0.927, 0.039). simple less-invasive preserving for might be potentially safe from an perspective.
