A case report on result of posterior fossa decompression on syringomyelia in a case of chiary type I malformation

The prime objective in the surgical treatment of Chiari malformation (CM) and/or syringomyelia (SM) is based on the restoration of the normal cerebrospinal fluid (CSF) dynamics at the craniovertebral junction through the creation of a large artificial cisterna magna. In this case a patient came to our hospital with type 1 chiary malformation having large syrinx which underwent posterior fossa decompression by midline sub occipital craniectomy with subpial cerebellar tonsillar resection which after one year of follow up we have found significant resolution of syrinx radiologically
