Abstract: ObjectiveTo analyze the surgical effect and experience of the giant and long schwannoma in cervical spinal canal.MethodsThe clinical data of nine cases with giant and long schwannoma (consecutively occupying more than three segments) in cervical spinal canal admitted from March 2004 to August 2011 were analyzed retrospectively. They were performed surgical intervention by cervical posterior approach in 7 cases and anteriorposterior combined approach in 2 cases. Total resection were performed in 8 cases, including 4 under microscope, 2 under direct vision and 2 of deblocking excision, and partial excision in one case. The screw internal fixation of the posterior lateral mass was applied in 5 cases, the combined internal fixation of posterior pedicle screw and anterior titanium mesh was in 2 cases, and internal fixation was not applied in 2 cases.ResultsThe intraoperative hemorrhage volume was 500 to 1 150 ml with an average of 846±147 ml. One patient was found superficial wound infection after the surgery. After 10 to 43 months followup (mean, 23.6±6.4 months), the neural symptoms of 88.9% of the patients were significantly improved. Radiography showed that there was no occurrence of cervical instability and no recurrence of the tumors after the surgery.ConclusionsSurgical resection is the best treatment for giant and long schwannoma in cervical spinal canal, but it is rather difficult, highly risky and obviously individualized as well. Preoperative reasonable surgical plan should be made necessarily according to the location of the tumor and the relationship between tumor and the surrounding structures.
