Abstract

Abstract:

Objective　To evaluate clinical outcomes and anatomy of single-stage one-side lamina retaining posterior approach for resection of C1/2 schwannoma.　Methods　From Jan 2009 to Jan 2014, C1/2 schwannoma cases admitted in our department were selected according to following indication: (1) Epidural tumor; (2) lateral growth pattern which went through C1/2 lamina space; (3) the diagnosis of schwannoma was suggested by MRI. 9 cases were collected, among which 5 were male and 4 female, and whose average age was 47.2 y (25~74 y). JOA score, radiological images, operative time, bleeding amount, complications and atlanto-dental interval of lateral cervical X-ray picture at last follow-up were recorded and analyzed.　Results　All cases were successfully followed up for 6 to 48 month, with an average of 20 months. There was no recurrence, cervical instability and post-operative axial pain reported. At last follow-up, all of the atlanto-dental intervals were less than 2mm. Pre-operative JOA score was improved from 11.3±1.64 to 15.4±0.70 at the final follow-up of 8 neurologically impaired patients, and the difference was significant（P<0.05）.　Conclusion　MRI should be used to recognize the tumor pre-operatively. After careful patient selection, the single-stage one-side lamina retaining posterior approach for resection of upper cervical schwannoma has a satisfied clinical outcome, few complications and good prognosis.
