Supraorbital transciliary approach as primary route to fronto-basal high grade glioma resection with 5-Aminolevulinic Acid use: Technical note.

Background: Gliomas are diffuse intra-axial lesions, which can be accessed by multiple surgical corridors for a same location depending on the surgeon's preference. 5-Aminolevulinic Acid use facilitates the extend of resection in case of high-grade gliomas, especially when differentiating normal brain from tumor periphery is challenging.

Methods: Complete resection of glioblastoma via a supraorbital transciliary approach with 5-Aminolevulinic Acid use was performed without any complications, as demonstrated on postoperative MRI.

Results: Patient was discharged on the third postoperative day. Wound follow-up shows good cosmetic result. Patient underwent concomitant chemo-radiation (Temozolomide- 60Gy) and adjuvant chemotherapy (Temozolomide). No tumor recurrence was noted at six months follow-up.

Conclusion: In selected cases, supraorbital transciliary approach could be proposed as primary approach as it provides the advantage of full control over all the vasculo-nervous structures at skull base without the necessity of protective brain retractor use while the 5-Aminolevulinic Acid use allows a gross total resection.
