Sellar Diaphragm Reconstruction with Tachosil During Endoscopic Endonasal Surgery: Technical Note

Abstract This report introduces a new closure technique for the management of intraoperative cerebrospinal fluid (CSF) leakage during endoscopic endonasal surgery. The procedure is based on the combination of a traditional autologous tissue flap with a heterologous fibrin graft (TachoSil). We performed a retrospective analysis on 121 patients with pituitary adenomas treated in our center by the senior neurosurgeon (author V.R.B) in the previous 4 years. Only one patient (0.8%) developed a CSF leakage and no adverse events were found related to the use of TachoSil. Compared with other techniques used previously, sellar diaphragm reconstruction with TachoSil seems to be an effective and inexpensive alternative.
