Closure of Spontaneous Cerebrospinal Fluid Leakage via Fistula at the Lateral Wall of the Sphenoid sinus using a Bone Pile

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.
