The history of autologous fat graft use for prevention of cerebrospinal fluid rhinorrhea after transsphenoidal approaches.
Presented herein is a review of the history of fat graft use in preventing iatrogenic cerebrospinal fluid (CSF) rhinorrhea after transsphenoidal surgery. Since the first transsphenoidal surgeries were described in the early 1900s, the techniques of sellar packing to prevent CSF leak have evolved. Kanavel, Halstead, and Cushing used bismuth- or iodine-soaked gauze. ⋯ The use of autologous fat graft for this purpose has only been reported in recent decades. Montgomery was the first to use abdominal fat to obliterate the middle ear cavity in 1964, and Collins reported the first transsphenoidal application of fat graft in 1973. Other reports by Kirchner, Tindall, and Wilson followed.

Endoscopic third ventriculostomy (ETV) is a routinely used alternative to ventriculoperitoneal shunt in patients with obstructive hydrocephalus. We attempted to determine the usefulness of the surgeon's intraoperative impression and postoperative period intracranial pressure monitoring that may help guide clinicians in predicting the early functional outcome of ETV. ⋯ ETV is a valuable means of treating obstructive hydrocephalus. By considering the surgeon's intraoperative impression and postoperative ICP monitoring course, some of the uncertainty around its functional outcome can be overcome. The surgeon's impression and the ICP monitoring offer approximately the same predictive quality for ETV outcome.
