Abstract
Temporal bone cerebral spinal fluid (CSF) leak is a condition characterized by continuous
CSF leakage from the intracranial cavity into the middle ear space. Prompt surgical
management is warranted as temporal bone CSF leaks may lead to serious infections
such as meningitis and encephalitis. There are several methods and materials utilized
to repair tegmen defects that cause CSF leaks. Herein, we describe a novel technique
to repair the tegmen in patients with temporal bone CSF leak utilizing a tragal cartilage
butterfly graft. Cartilage is a readily available, generously biocompatible, resistant
to deformation and an inherently pliable graft material. Butterflied cartilage grafts
provide unique benefit allowing both intracranial and extracranial support to seal
tegmen defects with the placement of a single piece of graft material.
