Vascularized temporoparietal fascial flap for the treatment of a traumatic cerebrospinal fluid fistula in the middle cranial fossa. Technical note.

The temporoparietal fascial flap (TPFF) is a vascularized pedicle flap commonly used in head and neck reconstructions. The authors describe the use of a TPFF in repairing a large traumatic middle cranial fossa CSF fistula via a middle cranial fossa approach. During the 18-month follow-up, the patient had no further CSF leakage or meningitis. The use of a TPFF for the repair of a traumatic CSF fistula has not been described in the literature. The authors recommend the use of a TPFF in treating recurrent or large middle cranial fossa CSF fistulas. The flap provides a well-vascularized thin layer that can be ideal in middle cranial fossa repair, and its proximity to the operation site is perfect as well.
