Project Description

Compression on the cerebellar tonsils can be the result of a common neuroanatomical pediatric condition called a Chiari malformation. The cerebellum can be abnormally pushed through the foramen magnum, resulting pain, sensory issues such as pins and needles, and motor issues including muscle weakness. The severity of the malformation may call for a surgical approach of the posterior skull and cervical spine to make space for the cerebellum and cerebrospinal fluid. A Chiari decompression involves removing portions of the occipital bone and C1 vertebrae and expanding the space contained by the dura mater in this area.Among neuroanatomical abnormalities, the Chiari malformation is common in pediatric patients. This piece outlines the steps of the Chiari decompression as a course of surgical treatment. Future pediatric neurosurgeons should be aware of the surgery, and be able to quickly reference its’ key process when needed. The layout of this piece includes important steps, a location reference image for the positioning of the incision in relation to the malformation, and information about intraoperative ultrasound.
