Clinical Comparison of Curative Effect after Different Surgical Treatment of Arnold-Chiari Malformation

Objective To investigate the surgical treatment and curative effect of Arnold-Chiari malformation.Method The surgical treatment of 102 patients with Arnold-Chiari malformation diagnosed by magnetic resonance imaging(MRI) was analysed retrospectively.They were performed differently by posterior cranial fossa decompression,or posterior cranial fossa decompression with reconstruction of cistemals,or posterior cranial fossa decompression with reconstruction of cistemals and cerebellar tonsillectomy.Results The clinical signs and symptoms were relieved and improved in 89 cases.So the total efficient rate after operation was 87.3%;the efficient rate after three operation were 97.5%,80.5% and 81.0%,respectively,in which treatment with posterior cranial fossa decompression showed more improvement than the other two approaches(P0.05).Conclusion Posterior cranial fossa decompression is a simple and effective method for treatment of Arnold-Chiari malformation.
