Two cases of cerebrospinal fluid leakage reconstruction with polycaprolactone-based mesh buttress and nasoseptal flap during endoscopic endonasal transsphenoidal surgery

In performing endoscopic endonasal transsphenoidal approach surgery, intraoperative cerebrospinal fluid (CSF) leakage frequently occurs. While a small amount of CSF leakage can be easily handled, in the case of a high flow or a large amount of CSF leak, simply applying a nasoseptal flap may cause flap failure due to flow pressure. The best buttress for this situation would be septal bone or fascia lata; however, it is difficult to use septal bone if it is thin or not sufficiently secured to cover the defect area or in the case of revision case and when donor morbidity is increased for fascia lata harvest. To address this concern, in this study, we report the cases of sellar floor reconstruction using a polycaprolactone-based mesh as buttress.
