Abstract：Objective To evaluate the curative effects of posterior fossa decompression (PFD) and posterior cranial fossa plastic repair (PCFPR) on Chiari malformation type Ⅰ complicated with syringomyelia (CMTICS).Methods The clinical data of 38 patients with CMTICS,of whom,12 underwent PFD and 26 PCFPR including decompression of posterior cranial fossa and dura plastic repair from January,2013 to January,2016,were analyzed retrospectively.Results Of 38 patients followed up for 12 months,31 received MRI examination and 7 not during the following up.The rate (41.6％,5/12) of postoperative complications occurrence was significantly lower in 12 patients undergoing PFD than that (76.9％,20/26) in 26 patients undergoing PCFPR.There was insignificant difference in the prognoses evaluated by Tator scale between both the groups (P＞0.05).The rate (90.0％,18/20) of syringomyelia improvement was significant higher in 20 patients who were followed up with MRI after PCFPR than that (54.5％,6/11) in the 11 patients who were followed up with MRI after PFD (P＜0.05).Conclusions The incidence of postoperative complications induced by PCFPR is significantly higher than that induced by PFD,but its curative effect on the syringomyelia is significantly better than that of PFD in the patients with CMTICS.PCFPR is similar to PFD in the effects on CMTICS evaluated by Tator scale.
