Official Title: Posterior Fossa Decompression With or Without Duraplasty for Chiari Type I Malformation With Syringomyelia

Brief Summary: The purpose of this study is to determine whether a posterior fossa decompression or a posterior fossa decompression with duraplasty results in better patient outcomes with fewer complications and improved quality of life in those who have Chiari malformation type I and syringomyelia.

Detailed Summary: Participants with Chiari Malformation type I and syringomyelia will be randomized to either have a posterior fossa decompression done with or without duraplasty. The participant will then return to the neurosurgeon's office at the following time points which are consistent with standard of care practice: < 6 weeks, 3-6 months, and 12 months. At these visits, the clinician will complete a physical exam and the participant will report on the prognosis of symptoms and complete two quality of life questionnaires. A brain and cervical spine MRI will be performed 12 months after the decompression.

Current Primary Outcome:

  • The number of participants with complications such as cerebrospinal fluid (CSF) leaks, pseudomeningoceles, infections, aseptic meningitis, hydrocephalus, and revisions. [ Time Frame: 6 months from decompression ]
  • The number of participants with complications such as cerebrospinal fluid (CSF) leaks, pseudomeningoceles, infections, aseptic meningitis, hydrocephalus, and revisions. [ Time Frame: 12 months from decompression ]


Original Primary Outcome: Same as current

Current Secondary Outcome: Compare the change in size of syrinx before and after decompression. [ Time Frame: 12 months ]

Syrinx size will be measured with radiographic imaging pre-operatively and 12 months post-operatively.


Original Secondary Outcome: Same as current
