BACKGROUND Chiari I malformations secondary to other causes represent a small subset
of presenting symptomatic cases. Typically, the primary cause of the malformation is …

Objective This study was aimed to achieve gross-total removal of a chordoma of the
craniocervical junction via an endonasal approach (Fig. 1). Design The present study is a …

Objective While the endoscopic endonasal approach (EEA) has gained widespread
acceptance for the resection of clivus chordomas, conventional transcranial approaches still …

Chordomas are rare tumors that occur at an incidence rate of 0.8 per 100,000. Thirty-five
percent of chordomas occur in the spheno-occipital region. We present a case of a clival …

Surgery for chordoma in the craniocervical junction is challenging because tumor
occasionally extends below the inferior limit of endoscopic endonasal surgery (EES), which …

BACKGROUND The endoscopic endonasal approach has been recently proposed for
cranio-vertebral junction lesions. The more common indication for this sagittal extension of …

Chordomas are rare, benign tumors believed to develop from notochordal rest cells and to
form along the neuraxis. Clival chordomas often present on invasion of surrounding …

OBJECTIVE: Cranial base chordomas are difficult lesions to treat. The endoscopic
endonasal approach (EEA) takes advantage of the natural sinus corridor and may provide a …

Objective To assess our clinical experience in treating midline intracranial pathology using
minimally invasive surgical techniques. Design Retrospective chart review of patients …

Craniovertebral junction chordomas can represent a surgical challenge, especially when
intradural extension and contact with neurovascular structures is involved. To date, there is …
