Abstract：Objective To investigate the surgical methods and outcomes of dumb-bell tumors at high cervical spine.Methods The clinical data of a patient with a dumb-bell tumor at C2～3 canal that was surgically resected through an extreme lateral approach using a posterior midline small incision were retrospectively analyzed,and the related literatures were reviewed and analyzed.Results A 55-year-old male presented with progressive paresthesia and weakness of the extremities for more than 2 years,and he fell down 4 hours prior to admission and caused pain in various parts of the body.The enhanced MRI of the cervical spine showed a intra-and extra-medullary lesion at the C2～3 level,causing compression and edema of the cervical cord at the same level,and the lesion encircled the left vertebral artery,suggesting a neurogenic tumor.The CT scan and three-dimensional reconstruction showed partial destruction of the left side of the C2～3 vertebral body and the pars of the cervical spine.After completing preoperative preparations,the tumor was resected through a posterior lateral approach using a posterior midline small incision.The tumor was completely resected,and no internal fixation was performed.After 14 months of follow-up,the muscle strength of the extremities was fully recovered,and the patient could engage in daily activities.The enhanced MRI of the cervical spine showed no recurrence of the tumor,and the cervical spine was stable as assessed by dynamic X-ray examination.Concluions The results suggest that the resection through an extreme lateral approach using a posterior midline small incision for large dumb-bell tumors in the cervical spine can be performed without moving the patient's position and without compromising spinal stability.No additional internal fixation is required during the operation,which is safe and effective,providing an alternative approach for the resection of these tumors.
