Abstract: Although the cervical intraspinal tumors have been long successfully removed, the cervical intra-and extraspinal tumors have not been viewed with optimism by surgeons. According to the relationship between tumors to intrvertebral foramen,the author proposed a classificaton system (three types) for 27 cases as a means to choice the different surgical method. Type Ⅰ (13 cases): The tumors were mainly located in vertebral canal, and limited in 1cm form intervertebral foramen that gently magnified. The posterior midline applied for type Ⅰ tumor. Type Ⅱ(4 cases): The antercervical accesses were employed to excise the tumors mainly located in extravertebral canal, a little portion in vertebral canal. Type Ⅲ (10 cases): Patients with dumbbell tumor had a larger intervertebral foramen. We performed two-stage combined surgery through the antercervical and the posterior midline route to excise the tumors. The results were total resection (25 cases), nearly total resection (2 cases). 23 cases patients could regain to work during follow-up interval of 6～79 months. For cervical intra-and extraspinal tumors, the different surgical approach should be applied to facilitate total resection, and can maintain the stability of spine and protect vertebral artery.
