Objective: This paper attempts to study and analyze the effects on the spinal cord and cranial nerve blood supply after the decom- pression of the spinal cord injury associated with cervical spinal stenosis.

Method: With white rabbits as the subjects, the author conducted decompression on the subjects suffering from spinal cord inju- ries associated with cervical spinal stenosis and observed their somatosensory evoked potentials (SEPs) and serum myelin basic protein (MBP) concentrations.

Results: judged by the kinematic scores and SEPs, Group A, B, C, D and E were better than other groups in terms of neurological recovery, and Group F and G were better than Group H, I and J. There are no distinctive differences between Group H and I and Group J. According to the analysis of serum MBP concentration and histology, the longer the spinal cord is compressed, the more serious damages the spinal cord structure will suffer.

Conclusion: Early decompression can effectively maintain the spinal cord structure of the spinal cord injury patient and help recover the cranial nerve functions.
