An axial CT of a patient with a spontaneous CSF leak reveals a defect in the posterior table of the left frontal sinus.
After intrathecal fluorescein is administered, an exposed frontal recess encephalocele is seen.
A defect in the skull base is measured with a sterile ruler.
A small cribriform plate encephalocele is observed only after removing the middle turbinate.
Septal bone is used as an underlay graft in the repair of this skull base defect in a patient with a spontaneous leak and encephalocele. (Defect measured approximately 7mm.)
Triplanar images help to identify and conceptualize the location of this lateral recess encephalocele.
This image represents an endoscopic view with a 70-degree telescope through the left frontal recess. A large defect is noted, and the meningocele has been resected. Repair of the leak can be performed with an underlay fascia graft and an anterior-based pedicled mucosa flap.
Triplanar images of a patient with a left lateral recess meningoencephalocele. The probe indicates that access to the defect is performed through the maxillary sinus and pterygopalatine fossa.
