Endoscopic endonasal resection via a transsphenoidal and transpterygoid approach for sphenoid ridge meningioma extending into the sphenoid sinus: A case report and literature review

Highlights

• Extracranial meningiomas are rare, of a secondary type, and of intracranial origin.

• We describe a case of sphenoid ridge meningioma extending into the sphenoid sinus.

• The tumor was resected by staged transcranial and endoscopic endonasal resection.

• A transsphenoidal and transpterygoid approach was used.

• This approach provided adequate visualization for removal of the tumor.

Abstract

Introduction

Large sphenoid ridge meningiomas are surgically challenging because of their extension to adjacent structures. Extracranial meningiomas are very rare; most are of the secondary type and have an intracranial origin. Improved surgical methods are required for treatment of this entity.

Presentation of case

Here, we describe a case of a huge sphenoid ridge meningioma extending into the sphenoid sinus that was resected by staged transcranial and endoscopic endonasal resection via a transsphenoidal and transpterygoid approach. It was possible to excise the tumor from the sphenoid sinus in a minimally invasive manner via this approach.

Discussion and conclusion

The transsphenoidal and transpterygoid approach was useful for providing a surgical field that allowed adequate visualization for removal of a sphenoid tumor that had expanded well into the lateral fossa of the sphenoid bone.
