The process of resecting spinal tumors, especially rare spinal tumors such as “Chordoma clivus,” is one of the major challenges facing neurosurgeons. The reason for these challenges lies in the significant depth of the tumor’s location at the skull base, in addition to its proximity to vital neural structures and blood vessels. In this article, we review a modern technique known as “EF-SCITA” (the extended far-lateral approach to accessing the infratentorial space) as an effective method for intradural resection of “Chordoma clivus.” We will discuss the case of a 68-year-old female patient where this technique was applied and highlight the associated benefits and positives. Through this study, we aim to provide new insights on how to manage these rare tumors, focusing on preserving neural functions during surgery, which illustrates the vital importance of a well-considered surgical approach in achieving positive outcomes for patients.
Challenges of Chordoma Surgery in the Cranial Region

The surgery focuses on preserving crucial neural functions, and success in this surgery necessitates thorough knowledge of the anatomy of the skull base and the best safe approaches to the tumor.
In recent years, various surgical methods have been developed to access chordoma tumors. The trend towards using endoscopic techniques stands out due to their numerous benefits, such as reducing the rate of exposure to important nerves and minimizing surgery-related scarring. The new surgical approach, which is the far-lateral infratentorial endoscopic technique used in the studied case, serves as a safe and effective option that can minimize postoperative risks.
Clinical Description of the Studied Case
An example is provided of a 68-year-old female patient who presented with sudden left eyelid droop for two weeks.
