Abstract
The aim of this study was to elucidate the risk factors for cerebrospinal fluid (CSF) rhinorrhoea following transsphenoidal surgery and discuss its prevention and treatments. We retrospectively reviewed 474 consecutive cases of pituitary adenoma treated with 485 transsphenoidal surgical procedures from January 2008 to December 2011 in our department. We analysed the incidence of intra- and post-operative CSF leakage and outcomes of various repair strategies. Intra-operative CSF leakage was encountered in 85 cases (17.9%), and post-operative CSF rhinorrhoea in 13 cases (2.7%). Seven of the 13 patients with post-operative CSF rhinorrhoea did not experience intra-operative CSF leakage; three of these patients had adrenocorticotropic hormone-secreting adenomas. Of the remaining 6 patients with both intra- and post-operative CSF leakage, 2 were treated for giant invasive prolactinomas, and 2 had previously undergone transsphenoidal surgery. In eight patients, the leak was resolved by lumbar puncture, lumbar external drainage, resting in a semi-reclining position, or other conservative treatment. Two CSF leaks were repaired with gelatine foam and fibrin glue using a transsphenoidal approach, and two with autologous fat graft and sellar floor reconstruction using a transnasal endoscopic approach. After undergoing two transnasal endoscopic repairs, one patient with post-operative CSF rhinorrhoea was successfully treated by further lumbar subarachnoid drainage. In conclusion, procedures using gelatine foam, fibrin glue and autologous fat graft are common and effective techniques for the management of CSF rhinorrhoea after transsphenoidal surgery. When a CSF leak is detected during transsphenoidal surgery, thorough sellar reconstruction and long-term follow-up are necessary.
