Underlay hourglass-shaped autologous pericranium duraplasty in key-hole retrosigmoid approach surgery: Technical report

摘要

Background:Cerebrospinal fluid (CSF) leakages represent a major complication of skull base surgery. Watertight dural suture is challenging, and different ways to reinforce it have been proposed. Since 6 months, we use locally harvested autologous pericranium graft for dural repair in retrosigmoid approach.
