Endoscopic Posterior Resection of C2 Osteoid Osteoma with 3 years follow up.

Case report and literature review. To present and describe the surgical technique of the case with 3 years follow-up, the longest one reported to date involving posterior endoscopic management of a C2 osteoid osteoma. Summary: The development of spinal endoscopic techniques has enabled the treatment of degenerative spinal disorders and has expanded their indications to include spinal tumor pathology. This report represents the case with the longest follow-up reported to date regarding the use of endoscopic techniques in the treatment of cervical osteoid osteoma. A 10-year-old patient presented with a 2-year history of cervical pain. Diagnostic imaging with Computed Tomography (CT) and Magnetic Resonance (MR) revealed an osteoid osteoma located in the C2 lamina and pedicle. The patient underwent posterior cervical endoscopy with complete tumor excision. Clinical and radiological follow-up demonstrated tumor resection with a significant reduction of symptoms. No signs of tumor recurrence were observed at 3 years of follow-up. Endoscopic techniques have expanded their indications to include spinal tumor pathology. In experienced hands, this is a safe technique that allows direct visualization of tumor resection. Its advantages include minimal morbidity, reduced postoperative pain and discomfort, decreased analgesic dependence, and improved cosmetic outcomes. • Pediatic patient. • Full endoscopic posterior resection is feasible for osteoid osteoma in upper cervical spine. • Direct endoscopic visualization allows tumor resection in contact with the spinal cord. • Endoscopy overcomes limitations of percutaneous radiofrequency near neural structures. • Ultra–minimally invasive approach avoids open surgery and potential fixation-related morbidity used in cases Osteoid Osteoma near to spinal cord.
