| Objective To systematically review the clinical curative effect of foramen magnum decompression with and without duraplasty in the treatment of Chiari I malformation with syringomyelia. Methods The follow-up randomized controlled studies ofChiari I malformationwere performed by the retrieval of PubMed, OVID, Wanfang Database, CNKI and VIP database from their building time to the year 2015. Meta analysis was performed using revman5.2 software. Results Syringomyelia reduction rate[OR=0.20,95%CI (0.11-0.39),P=0.11]and the clinical improvement rate[OR=0.11,95%CI(0.05-0.23),P=0.79] of foramen magnum decompression with duraplasty group were better than those of foramen magnum decompression without duraplasty group, and the difference was statistically significant. There were no statistical differences in early postoperative complication rate[OR=0.62,95%CI(0.17-2.29),P=0.71]. Conclusion The perspective of the existing clinical evidence, surgical methods in the treatment of Chiari I malformation with syringomyelia in FMDD is superior to that of FMD in terms of the syringomyelia reduction rate and the clinical improvement rate. |
