Cerebellar tonsillectomy with suboccipital decompression and duraplasty by small incision for chiari i malformation with syringomyelia: long term follow-up of 76 surgically treated cases

Abstract

Cerebellar tonsillectomy with suboccipital decompression and duraplasty can provide long-time cure for most CM I cases. Early diagnosis and surgery is necessary to improve the surgical effect. A 3~4cm incision around foramen magnum is enough for these operations and may be conducive to reduce postoperative complications.
