Brief Summary:
This research study is to find out which types of dural grafts used during surgery for Chiari Malformations are superior. We believe that autologous dural grafts are superior to non-autologous grafts.

Condition or disease Intervention/treatment Phase
Chiari Malformation Procedure: decompression of Chiari malformation Not Applicable

Detailed Description:
The study compares autologous grafts vs. non-autologous grafts. Non-autologous grafts include synthetics and grafts from animals. Autologous grafts have a better side-effect profile than non-autologous grafts. We believe this improved side-effect profile will result in a decreased incidence of reoperation for post-operative infections and post-operative fluid collections (pseudomeningoceles and seromas). Study is open to all non-pregnant minor and adult subjects. Subjects must have symptomatic Chiari Malformation described as > or equal to 6mm descent of the cerebellar tonsils below the foramen magnum with accompanying headaches and/or neurologic findings (arm pain/weakness, myelopathy, etc.). After the 12-month follow-up is completed on the first 100 subjects there will be an interim analysis of the results in order to determine whether one of the treatments has a statistically superior outcome. If a statistically superior outcome is noted, the trial will stop after being reviewed by a data monitoring committee. If no statistically significant difference is seen at one year, the study will continue until the 12-month follow-up is completed on the 200th patient.

Arm Intervention/treatment
Active Comparator: surgery - autologous graft
surgical intervention: decompression of Chiari malformation by suboccipital craniectomy using autologous graft
Procedure: decompression of Chiari malformation
Removal of a small section of bone at the back of the skull (posterior foramen magnum decompression) or upper cervical spine. During surgery, the covering of the brain (dura) is enlarged with a graft (autologous or non-autologous).

Active Comparator: surgery - non-autologous graft
surgical intervention: decompression of Chiari malformation by suboccipital craniectomy using using non-autologous graft
Procedure: decompression of Chiari malformation
Removal of a small section of bone at the back of the skull (posterior foramen magnum decompression) or upper cervical spine. During surgery, the covering of the brain (dura) is enlarged with a graft (autologous or non-autologous).




Primary Outcome Measures :
  1. Complications encountered during the subject's post-operative care [ Time Frame: 2 years ]
    After the 12-month follow-up is completed on the first 100 subjects there will be an interim analysis of the results in order to determine whether one of the treatments has a statistically superior outcome. If a statistically superior outcome is noted, the trial will stop after being reviewed by a data monitoring committee. If no statistically significant difference is seen at one year, the study will continue until the 12-month follow-up is completed on the 200th patient.
