The effect of prior radiation on the success of ventral skull base reconstruction: A systematic review and meta‐analysis

Exposure to pre‐operative radiation may put patients at an increased risk of skull base reconstructive failure. A systematic search identified studies which included patients receiving ventral skull base reconstruction in the setting of pre‐operative radiation. A meta‐analysis using a random effects model was conducted to estimate an odds ratio of cerebrospinal fluid (CSF) leak in patients exposed to pre‐operative radiation. A meta‐analysis of 13 studies demonstrated that the odds ratio of CSF leak was 1.73 (95% CI 0.98–3.05). The majority of studies (77%) used vascularized tissue grafts for reconstruction. We identified an increased incidence of CSF leak among patients undergoing ventral skull base reconstruction after prior radiation therapy, although not of statistical significance. Skull base surgeons should exercise caution whe n planning reconstruction in this population. View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.
