Chiari MalformationWhen the descended brain tissue blocks this passageway, there is the potential for serious health issues to occur, although not all cases are symptomatic. What is Arnold-Chiari?The parts of the brain involved are the cerebellar tonsils and the medulla. These structures are usually contained within the skull, but in the case of Arnold-Chiari, they herniate into the space between the skull and the spine. This acts like a plug or cork, blocking the normal flow of cerebral spinal fluid between the skull and the spine.While some cases are harmless and do not produce noticeable symptoms, other cases can be extremely problematic. Many Chiari patients also have or develop the following spinal conditions: 
HydromyeliaSyringomyelia Tethered spinal cord syndrome Spina bifida Scoliosis Abnormal front to back spinal curvature Types of Chiari MalformationSymptomatic Arnold-Chiari is classified using a scale of four possible grades.* Type I is the most common and presents the best prognosis. Expressions may include: headaches, spinal syrinx development and damage to the cerebellar tonsils affecting brain function. * Type II is characterized by more extensive herniation of tissue, including the medulla oblongata and development of more serious issues, including: spina bifida cystica, paralysis and brain damage. * Type III is dire and usually found accompanied by serious neurological and often life threatening concerns. * Type IV is characterized by a complete lack of development in certain parts of the rear brain, usually resulting in death. Chiari Malformation AdviceThe most common form of Arnold-Chiari is certainly type I. This is the only type which can be developed after birth and the variety most often actively treated. The most popular approach to correcting this brain malformation is through decompression surgery.During this procedure, parts of the skull are removed and the foramen magnum may be enlarged, thereby taking pressure off the brain structures and facilitating a better flow of cerebral spinal fluid to prevent damage to the brain and spinal structures. It is always advised to seek any treatment for Arnold Chiari with a specialist in the field, since this is a very sensitive sector of brain/spine care and only a handful of the best neurosurgeons focus on the condition.
