Surgical treatment of type I Chiari malformation: the role of Magendie’s foramen opening e tonsils manipulation

| description | The treatment for type 1 Chiari malformation (CM 1) is one of the most controversial topics in the neurosurgical field. The present study evaluated two of the most applied surgical techniques to treat CM 1. Method 32 patients were evaluated and divided in two groups: group 1 had 16 patients that were submitted to decompression of occipital bone and dura mater of the craniovertebral junction (CVJ); group 2 also had 16 patients and in addition to the previous procedure, they were submitted to Magendie’s foramen opening e tonsils manipulation. The comparison between the groups included neurological exam and cerebrospinal fluid flow imaging during pre and postoperative periods. Results Both techniques were equivalents in terms of neurological improvement of the patients (p > 0.05), but the group 2 had more surgical complications, with relative risk of 2.45 (CI 1.55-3.86) for adverse events. Whatever the cerebrospinal fluid flow at CVJ, the patients of the group 1 achieved greater amount of flow than the group 2 (p < 0.05) during the postoperative period. Conclusion The cranial and dural decompression of the CVJ without arachnoidal violation was the best surgical intervention for treatment of CM 1, between these two compared techniques. |
