Endonasal Anterior C1 Arch Removal, Odontoidectomy, and Inferior Clivusectomy for Cervicomedullary Stenosis

We present the case of a 53-year-old woman with headaches and new-onset left-sided hemiparesis and paresthesia. Imaging revealed platybasia and abnormal ligament calcification at the craniocervical junction causing spinal cord compression. Surgical intervention involved a two-stage procedure: an endoscopic endonasal approach for anterior C1 arch removal, odontoidectomy, and inferior clivusectomy, followed by occiput to C4 posterior fusion. Postoperative imaging confirmed successful decompression at this level. The patient showed significant improvement at 6-week follow-up.
