Exoscopic supraorbital approach for a tuberculum sellae meningioma.

Tuberculum sellae meningiomas are midline anterior skull base tumors and account for approximately 10-15% of all intracranial meningiomas. Clinical presentation of tuberculum sellae meningiomas is mainly characterized by visual deficits due to optic chiasm compression or optic canal invasion. Treatment options for TSM typically involve surgical resection of the tumor. The relevant microsurgical anatomy of the suprasellar region was discussed. (1,2). Tumor size, anatomical variations can affect the best approach for these tumors, with several approaches been described to access the suprasellar region as pterional, endoscopic endonasal and supraorbital approach that was the choice for this case (3). Besides the surgical corridor, minimally invasive techniques that preserve the surrounding tissue are becoming increasingly popular and are perfectly suited to deep seated lesions. In this article, we present a surgical video of an exoscopic supraorbital approach for resection of a tuberculum sellae meningioma. This is a case of a 42-year-old right-handed female who presented with headaches and progressive vision loss. Patient presented with tumor growth and surgery was indicated. We chose the minimally invasive supraorbital approach and then used the exoscope as magnification tool visualization tool. Gross total resection and decompression of the optic canals was achieved with improvement of visual field deficits.
