Treatment of ChiariⅠmalformation with small bone-flap decompression of posterior fossa through neuroendoscopy / 局解手术学杂志

ABSTRACT

Objective To investigate the clinical efficacy of small bone-flap decompression of posterior fossa through neuroendoscopy in the treatment of ChiariⅠmalformation.Methods Retrospectively analyzed the clinical data of 44 cases of ChiariⅠdeformity/syringomyelia who were admitted into affiliated hospital of Xuzhou medical university from January 2013 to December 2016.And divided these patients into the observation group ( n=22,treated with small bone-flap decompression of posterior fossa through neuroendoscopy ) and the control group ( n=22,treated with posterior fossa decompression/tonsillectomy) according to surgical methods .The recovery time and the postoperative com-plications of the two groups were analyzed ,and the long-term efficacy and changes in spinal cord cavity were observed through the follow-up of 1 to 20 months.Results There was no death case in both of the two groups .The effective rate of the two groups were 86.36％and 86.36％respectively.The complication rate of the observation group was 27.35％, which was significantly lower than 77.3％of the control group with statistical significance(P<0.05).There was no significant differences in the recovery time ,postoperative curative effect and spinal cord cavi-ty changes between the two groups (P>0.05).Conclusion The treatment of Chiari Ⅰmalformation with small bone-flap decompression of posterior fossa through neuroendoscopy is a new surgical procedure with less trauma ,shorter hospital stay ,less complication and less effective compared with traditional method .
