Objective We describe our use of a perforated titanium plate to perform a partial posterior fossa cranioplasty in the treatment of cerebellar ptosis and dural ectasia following PFD. Methods Twelve patients who had undergone PFD underwent posterior fossa reconstruction using a titanium plate. Symptoms were related to either descent of the cerebellum into the decompression or to dural ectasia into the craniectomy defect. Results Twelve patients who had undergone large suboccipital craniectomies and who presented with persistent headaches and some with neurological symptoms related to syringomyelia, underwent re-operation with placement of a small titanium plate. Ten of twelve patients showed symptomatic improvement after re-operation. Conclusion Placement of a titanium plate appears to be an effective method of treatment of cerebellar ptosis and dural ectasia following PFD for Chiari malformation.
