The surgical treatment of craniopharyngiomas is challenging. An optimal surgical approach is extremely important to achieve complete removal of the tumor, which is often the goal of treatment. Conventionally, the endoscopic transsphenoidal approach is used for resection of craniopharyngiomas that are essentially confined to the sellar cavity, or have smaller suprasellar extension. However, the tumors located in the retrochiasmatic space are difficult to remove surgically due to a poor access. Traditionally, various transcranial microsurgical routes have been employed with limited success for resection of retrochiasmatic craniopharyngiomas. The transcranial approaches generally do not provide adequate exposure of the tumors originating in the space under the optic chiasm and nerves. Recently, the extended endonasal endoscopic surgical route, obtained by removal of the tuberculum sellae and planum sphenoidale, has been used with great success in the surgical management of tumors lying ventral to the optic chiasm, including craniopharyngiomas. It offers a direct midline access to the retrochiasmatic space and provides excellent visualization of the undersurface of the optic chiasm. It also allows extracapsular dissection using binostril-bimanual technique and facilitates complete removal of these formidable tumors. In this report, we describe step-by-step, the technical details of the endonasal endoscopic transplanum transtuberculum approach with emphasis on the operative nuances for removal of retrochiasmatic craniopharyngiomas.
