The Analysis Of Chiari Malformation With Syringomyelia Symptoms Between Before And After Surgery

ObjectiveTo analysis the changes in symptoms of Chiari malformation withsyringomyelia patients before and after suboccipital decompression.Methods61cases of Chiari malformation with syringomyelia patients weretreated in our department from January2007to January2013wasresearched Retrospectively.All patients were treated by suboccipitaldecompression and dural plasty, according to the imaging data of6monthsto6years after surgery, divided into narrow hole group (group A) and notnarrow hole group (group B),and statistical analysis of a number of clinicalsymptoms between two group in preoperative, early postoperative and latepostoperative.ResultsShort-term efficacy:the ataxia improvement rate of group A was71.4%(5/7), group B was50%(1/2);the cranial nerve symptoms improvement rateof group A was71.5%(5/7),group B was83.3%(5/6);the movement and sensory disorders improvement rate of group A was36.8%(7/19)and37.5%(6/16),group B was21.4%(3/14)、33.3%(3/9); the pain and burningsensation symptoms improvement rate of group A was42.9%(6/14), groupB was40%(4/10). Long-term efficacy:96.7%(59/61) patients’ cerebellartonsil can be reset partially or completely,63.9%(39/61) patients’ hole wasnarrowed or even disappeared. the ataxia improvement rate of group A was85.7%(6/7), group B was50%(1/2);the cranial nerve symptomsimprovement rate of group A was71.5%(5/7),group B was83.3%(5/6);themovement and sensory disorders improvement rate of group A was78.9%(15/19)and75%(12/16),group B was35.7%(5/14)、22.2%(2/9); thepain and burning sensation symptoms improvement rate of group A was28.6%(4/14), group B was30%(3/10).The difference of themovement(P=0.029﹤0.05)and sensory disorders(P=0.017﹤0.05)improvement rate of long-term efficacy was statistically significantbetween group A and group B.ConclusionAfter surgical treatment,the patients expressed as ataxia and cranialnerve dysfunction symptoms most likely to recover; expressed asmovement and sensory disorders had poor short-term efficacy, but it mayhave some degree of long-term recovery, and the patients whose holenarrowed had recovered by a higher rate; while the performance of patientswith symptoms of pain, often poor recovery.
