Abstract:
Objective To explore surgical techniques and curative effects of microsurgical treatment for tumors in upper cervical spinal canal.Methods A total of 81 cases of tumors in upper cervical spinal canal had received microneurosurgery from January 1990 to December 2005.The operation was conducted through a posteromedial approach.A total tumor resection was performed in 73 cases of neurofibroma or neurilemmoma,3 cases of spinal meningioma,and 3 cases of ependymoma.A subtotal tumor resection was conducted in 2 cases of astrocytoma.Results A complete recovery was achieved in 75 cases,an improvement of symptoms was achieved in 4 cases,and no improvement in 2.No death was encountered.Follow-up observations were carried out in 52 cases for 3 months ～ 3 years(8.5?1.5 months).MRI examinations 3 months after operation in 15 cases found no residual or recurrent tumor.X-ray radiography under anteroposterior,lateral,and open-mouth view 6 months after operation in 32 cases showed no spinal deformation and good vertebral stability.Recurrence of intramedullary tumor was seen in 3 cases. Conclusions As long as tumors in upper cervical spinal canal are diagnosed,a microsurgical treatment should be given as early as possible.Appropriate selection of surgical approach,skillful microsurgical techniques in accordance with pathological types of lesions,and principles of minimal invasion are critical for the operation safety.
