A Case of Endoscopic Reconstruction of Skull Base Defect Combined with Meningoencephalocele in the Sphenoid Sinus / 대한이비인후과학회지

ABSTRACT

A skull base defect mainly occurs as a result of congenital defect, trauma, iatrogenic injury, inflammatory erosion, increased intracranial pressure or neoplasm. Meningoencephalocele is one of them resulting in skull base defects. Among the several types of meningoencephalocele, protrusion to lateral wall of sphenoid sinus in the basal type is less frequently encountered than other types and has not been reported in Korea. We report a patient with meningoencephalocele protruded to sphenoid sinus wall. It was successfully repaired with nasoseptal flap through the intranasal endoscopic approach.
