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.

Outcome Measures

Primary Outcomes (1)

  • Complications encountered during the subject's post-operative care

    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.

Study Arms (2)

surgery - autologous graft

ACTIVE COMPARATOR

surgical intervention: decompression of Chiari malformation by suboccipital craniectomy using autologous graft

Procedure: decompression of Chiari malformation

surgery - non-autologous graft

ACTIVE COMPARATOR

surgical intervention: decompression of Chiari malformation by suboccipital craniectomy using using non-autologous graft

Procedure: decompression of Chiari malformation

Interventions

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).
