Headache and Other Symptoms in Chiari Malformation Type I Are Associated with Cerebrospinal Fluid Flow Improvement After Decompression: A Two-Institutional Study

Further, our study suggests that the presence of improved CSF flow postoperatively could represent an objective indicator for improved patient outcomes.
