Objective: Describe the surgical management of clival chordomas in the pediatric population, with an emphasis on techniques of endoscopic endonasal surgery.

Finding: Endoscopic endonasal approaches to the clivus provide access from posterior clinoids to foramen magnum. The clivus is divided into thirds (superior, middle, and inferior), each with corresponding vascular and neural structures. The abducens nerve is at greatest risk for injury due to spread of tumor within the interdural space to Dorello's canal. Despite decreased pneumatization of the sinuses in pediatric patients, the same techniques can be applied to this population. The contralateral transmaxillary approach enhances the ability to achieve a gross total resection when tumor extends laterally into the petrous apex. A multi-layer reconstruction with vascularized tissue minimizes the risk of cerebrospinal fluid leak.

Conclusion: Endoscopic endonasal surgery can be safely applied to the pediatric population and provides the best opportunity for complete surgical excision for most tumors.
