Exclusive Endoscopic Removal of a Planum Sphenoidale Meningioma: A Case Report

Abstract

Midline suprasellar meningiomas have traditionally been removed through transcranial approaches. Endoscopic endonasal approaches have already been described for the removal of tuberculum sellae meningiomas (Cook), but their exclusive use for planum sphenoidale meningiomas has never been reported. A case report of a planum sphenoidale meningioma removed through a transnasal endoscopic approach is presented: the goal of this technique is tumor control with minimal morbidity. The anterior skull base defect has been reconstructed with a pedicled mucosa flap from nasal septum (Hadad-Bassagasteguy flap). The postoperative course was uneventful, and no sign of recurrence was noticed at the MRI control performed after 3 months.

Key words

planum sphenoidale meningioma - transnasal endoscopic approach - Hadad-Bassagasteguy flap - rhinoliquoral fistula - skull base plasty
