Objective To discuss the microsurgical therapeutic strategy of the Chiari's malformation associated with syringomyelia.Methods One hundred and twenty-seven cases which showed the symptoms of the Chiari's malformation associated with syringomyelia were confirmed by MRI. The hernia of tonsilla cerebelli was removed and the dissepiment that located in the mouth of the central canal of spinal cord was opened.Results All cases with Chiari's malformation associated with syringomyelia were found that the dissepiment was located in the mouth of the central canal of spinal cord. The hernia of tonsilla cerebelli of eighty-nine cases disappeared and syringomyelia decreased or disappeared through the average 1.5 years' follow-up.Conclusion The hernia of tonsilla cerebelli and the dissepiment located in the mouth of the central canal of spinal cord is one of the important reasons for the Chiari's malformation associated with syringomyelia. Removing the hernia of tonsilla cerebelli and opening the dissepiment that located at the mouth of the central canal of spinal cord are the practical method in treatment of the Chiari's malformation associated with syringomyelia.
