  ABSTRACT: Objective: To evaluate the role of expanded endoscopic endonasal approach in removal of clival chordomas. Patients & Methods: Nine patients with clival chordomas were operated upon in Cairo University hospital from September 2015 to September 2018 using the EEEA a recurrent case and seven new cases were involved in these study and ten operations were done. All patients had preoperative neurological and radiological examination. The study was focusing on the approach, efficacy of tumor removal, reconstruction of the base and complications related to this approach. Results: Nine patients were operated in this study in which ten operations were done. It included six males (66.6%) and three females (33.3%) with age ranging from 4 years to 63 years with average age 40.7 years. Headache and diplopia were the most common symptoms found in six patients (66.6%). Brainstem affection was found in two patients (22.2%). Lower cranial nerves affection was found in two patients (22.2%). One case developed CSF leakage postoperatively (11.1%). Two patients underwent tracheostomy. We achieve total removal in four patients (44.4%), near total removal in one patient (11.1%) and subtotal tumor resection in four patients (44.4%). Conclusion: EEEA for clival chordomas is safe and effective approach regarding the results of the incidence of complications, and the percentage of tumor resection.
