**10. Conclusion**

Spheno-orbital meningiomas are usually slow-growing skull base tumors revealed by proptosis or visual impairment. They typically present with significant tumoral spheno-orbital hyperostosis and a globoid or *en plaque* intradural portion. As their epicenter is located at the level of the lesser and greater sphenoid wings, they progressively extend to the temporal and infratemporal fossae, orbit, anterior clinoid process, and cavernous sinus, compromising the integrity of the optic canal, the superior orbital fissure, and the cranial nerves passing through. The reference treatment is currently optimal surgical resection after complete ophthalmological examination and radiological evaluation by MRI and CT scan. Although the risk of recurrence appears to be clearly correlated with the quality of the surgical resection, *Spheno-Orbital Meningiomas DOI: http://dx.doi.org/10.5772/intechopen.101983*

in cases with excessive meningioma adherence to critical anatomical structures, the removal of the tumor must be restricted in order to limit the comorbidities related to induced cranial nerves deficits. Radiation therapy is a safe option after surgery for recurrent or aggressive meningiomas.
