Clivus-Cervical Stabilization through Transoral Approach in Patients with Craniocervical Tumor: Three Cases and Surgical Technical Note

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 and complex, involving comprehensive approaches and advanced reconstructive techniques. This study, conducted at Mexico City’s National Institute of Cancerology, focused on three surgical cases that occurred in 2023 involving tumors at the CCJ: two chordomas and one prostate adenocarcinoma. We utilized a specialized technique: clivus-cervical stabilization reinforced with a polymethylmethacrylate (PMMA)-filled cervical mesh. Postoperatively, patients showed marked neurological recovery and reduced cervical pain, with enhanced Karnofsky and Eastern Cooperative Oncology Group (ECOG) scores indicating improved life quality. The surgical technique provided excellent exposure and effective tumor resection, utilizing PMMA-filled cervical mesh for stability. Tumoral lesions at the CCJ causing instability can be surgically treated through a transoral approach. This type of approach should be performed with precise indications to avoid complications associated with the procedure. © 2024 by the authors.
