Craniocervical tumors lead to cervical pain, instability, and neurological symptoms, reducing
the quality of life. Effective surgical intervention at the craniocervical junction (CCJ) is critical …

Introduction Malignancies of the clivus and petroclival region are mainly chordomas and
chondrosarcomas. Although a spectrum of malignancies may present in this area, a finite …

Due to their surgical inaccessibility and resistance to radiotherapy, clivus chordomas
represent a formidable therapeutic challenge. The transoral approach to chordomas of the …

Clival chordoma with occipito-cervical (OC) joint invasion can result in preoperative and
postoperative instability. The authors investigate the appropriate timing of OC fusion to …

BACKGROUND: Occipitocervical instability with vertical migration of the odontoid is a rare
but potentially debilitating anomaly of the craniocervical junction. Anterior decompression by …

BACKGROUND: The results of the surgical resection of 9 clival tumors using the enlarged
transcochlear approach (ETCA) are evaluated. The literature is reviewed to compare the …

Summary. Background: Occipital-cervical stability may be impaired in patients with primary
malignant or metastatic tumors of the cranio-cervical junction and the upper cervical spine …

BACKGROUND: Whether primary or metastatic, tumors of the craniovertebral junction (CVJ)
are rare and challenging. OBJECTIVE: To examine the surgical indications, operative …

Numerous procedures to expose the anterior clival region have been described, including
the transoral, transcervical, transseptal-transsphenoidal, transanteral, transnasal, bilateral …

Objective Tumours in the clival region are difficult to remove surgically. Before the 1970s,
clival tumours had very high mortality and morbidity rates. Methods An anatomic dissection …
