Endoscopic Resection of Clival Chordoma: A Tertiary Care Experience

The primary management of the rare tumor chordoma is always surgical. This study indicates the advantage of endoscopic approach for clival chordoma resection. This is a Retrospective case series of 7 endoscopically operated clival chordoma patients between May 2015 and April 2018 in our tertiary care hospital. 5 patients presented with primary disease and 2 were recurrent disease cases. Endoscopic endonasal transphenoidal approach with wide clearance of margins of tumor were performed in all 7 cases. High energy photon radiotherapy were delivered to all. All patients with primary disease as well as recurrent disease had no evidence of disease 24-32 months post surgery. Endoscopic endonasal transphenoidal approach for clival chordoma provides a safe and reliable tumor resection. This less invasive surgery can be considered as an alternative to traditional surgical technique with reduced morbidity. This approach represents a combination of various endoscopic surgical techniques which are minimally invasive and can be applied to ventral skull base surgery.
