Abstract
This report describes a case of spontaneous cerebrospinal fluid leak
through a narrow canal-like fistula in the lateral wall of the sphenoid
sinus, which was managed through rigid reconstruction. Rigid
reconstruction of the skull base was performed by fitting a pile-shaped
bone into the fistula like the pile-driving technique.
Keywords: skull base, rigid, pile-driving, high-resolution
