  https://patient.info/doctor/chiari-malformations

  All patients, whether they are suitable for surgery or not, should be considered for rehabilitative therapy and psychological support. […] A decision on whether to proceed to surgery should be based on the following approach: A multidisciplinary assessment is helpful, with neurologists, neurosurgeons and rheumatologists all giving an opinion about the patient. […] Patients most likely to benefit from surgery are those with reproducible neurological signs – eg, nystagmus, absent gag reflex, and demonstrably abnormal CSF flow in the hindbrain on cine MRI. […] Posterior fossa decompression with suboccipital craniectomy is the gold standard operative procedure. […] Chiari-related syringomyelia can be treated successfully with surgery. […] Studies suggest that early surgery in type II malformation results in a better outcome. Prompt decompression of a meningomyelocele in patients under the age of 2 years can lead to a significant reduction in mortality and morbidity.

• #6 Chiari Malformation – AANS

  https://www.aans.org/patients/conditions-treatments/chiari-malformation/

  Treatment of Chiari malformations and syringomyelia is very dependent on the exact type of malformation, as well as progression in anatomy changes or symptoms. […] Chiari I malformations that are asymptomatic should be left alone (this involves the majority of Chiari malformations). There is no indication for prophylactic surgery on these. If the malformation is defined as symptomatic, or is causing a syrinx, treatment is usually recommended. […] Surgical treatment of these malformations depends on the type of malformation. The goal of surgery is to relieve the symptoms or stop the progression of the syrinx or symptoms. […] Chiari I malformations may be treated surgically with only local decompression of the overlying bones, decompression of the bones and release of the dura (a thick membrane covering the brain and spinal cord) or decompression of the bone and dura and some degree of cerebellar tissue resection.

  Chiari 1 malformation management combines conservative and surgical approaches through a multimodal dynamic strategy. […] Medical management in Chiari 1 malformation is limited to supportive symptomatic (eg, headaches or neck pain) treatment. Non-steroidal anti-inflammatory drugs (NSAIDs), muscle relaxants, and physical support collars may provide symptomatic relief. However, these options offer little improvement of less common symptoms, for example, gait disturbance. […] Surgical treatment is typically reserved for patients who present with severe or worsening symptoms and who go on to have a confirmation of cerebellar descent on imaging and a Chiari malformation obstructing CSF flow confirmed by MRI. Surgery aims to provide decompression of the restricted cervicomedullary junction, allowing CSF flow to be restored to optimal levels. The primary approach involves performing a suboccipital craniectomy at the level of the C1 posterior arch (C1/2 laminectomy), with or without associated duraplasty.

  Chiari malformation is a condition where the lower part of the brain pushes down into the spinal cord. […] While surgical management can address headaches, hydrocephalus (abnormal build-up of fluid in the cavities deep in the brain) and nerve compression, physiotherapy addresses many of the other factors and sequalae including pain management, muscle imbalances, vestibular issues, and gait training. […] Surgical Chiari malformation treatment aims to decrease pressure on the brain and spinal cord to lesson or eliminate symptoms. The standard surgical intervention is a posterior fossa decompression where a small portion of the back of the skull is removed (craniectomy). […] Physiotherapy for Chiari malformation treatment consists of: Stretching – Pressure on nerves often leads to tightening of muscles; As children grow muscles become even tighter to accommodate for bone growth, Strengthening – Compression of nerves can cause muscle weakness and imbalances, Balance training – Sensory nerves can also be compromised leading to decreased sensation in the legs and feet leading to balance difficulties, Pain management techniques – use of manual therapy and soft tissue techniques to help manage headaches and back pain that may accompany scoliosis, Vestibular rehabilitation therapy – vestibular techniques can help resolve some of the audiovestibular symptoms including dizziness, nystagmus, Custom orthotics referral – Various orthotic devices such as ankle foot orthosis can be used to stabilize joints and increase independence.

  Posterior fossa decompression surgery aims to uncrowd the area at the base of the cerebellum where the cerebellar tonsils are pushing against the brainstem and spinal cord. This is done by performing a suboccipital craniectomy, a procedure in which the neurosurgeon removes a small portion of bone at the base of the skull, and often also a cervical laminectomy, a procedure in which the neurosurgeon removes a part of the bony arch of the first vertebra in the neck. Occasionally, the bony arches of additional vertebrae are removed too. […] Most patients who have the surgery do quite well and experience improvement of their symptoms.

  Accordingly, for several years, we have been performing a less invasive operation in which the dura mater is not opened during surgery. At this time, we have seen excellent clinical and radiographic results without any significant operative complications after bony decompression without dural opening. The complication rate is very low2.6 percent. This is important because the complication rate after opening the dura mater during surgery has been reported to be 15-25 percent. […] A small percentage of patients treated with this less invasive option will require a second surgery to open the dura mater for further relief of symptoms.

During this surgery, your surgeon will remove a small part at the bottom of your skull and sometimes part of your cervical spine to correct the irregular bony structure. The surgeon also may open and widen the membranes (called dura) that surround your brain and spinal cord. This makes additional space so your cerebrospinal fluid can circulate. […] Electrocautery. Some neurosurgeons recommend this procedure, which uses high-frequency electrical currents to shrink the lower part of the cerebellum so that it retracts out of the foramen magnum. […] Spinal laminectomy. During this procedure, a part of your spinal canal is removed to increase the canal’s size and reduce pressure on your spinal cord and nerve roots. […] If you have hydrocephalus, your doctor may recommend you have a shunt placed to drain the excess cerebrospinal fluid away from your brain to another part of your body where it can be absorbed.

  A Chiari malformation is a structural abnormality in your skull that causes part of your brain to move into your spinal canal. Surgery may help. […] Your healthcare provider will make a treatment plan based on the severity of your symptoms. If you don’t have symptoms, you don’t need treatment. Your provider will monitor your health with regular MRIs. […] Treatment for mild symptoms like a headache or neck pain may include: Taking pain medications or medications to help you manage your symptoms. Participating in massage therapy or physical therapy. Limiting your physical activities like heavy lifting. Using devices like hearing aids or glasses to help with hearing or vision loss. […] Severe Chiari malformation cases may need surgery. Surgical procedures may include: Craniectomy: Your surgeon will remove a piece of your skull to relieve pressure on your brain and help cerebrospinal fluid flow. Posterior fossa decompression: This is the most common procedure to treat a Chiari malformation. Your surgeon relieves pressure on your brain, giving it more room, by removing a part of the back of the skull called the posterior fossa. Laminectomy: Depending on how severe the Chiari malformation is, your surgeon may remove a small portion of bones covering your spinal column to restore the flow of cerebrospinal fluid and allow more room for your spinal cord. Duraplasty: In this decompression surgery, your surgeon opens the dura (a membrane on the outside of your brain). Then, your surgeon sews in a patch to make the membrane larger so your brain has more room. This procedure enlarges the area and relieves pressure on your brain. Electrocautery: To create more room and allow the cerebrospinal fluid to drain, surgeons may apply a small amount of electricity to shrink a small part of your brain called the cerebellar tonsils. The cerebellar tonsils retract without causing brain or nerve damage. Shunt placement: Your surgeon will implant a shunt or tube in your skull to collect excess CSF if you have hydrocephalus. The fluid drains away from your skull and brain and collects in another part of your body.

  An alternative treatment for non-communicating hydrocephalus is a surgery known as endoscopic third ventriculostomy (ETV). In these cases the blockage of CSF flow occurs beyond the third ventricle and presumes that the ability to absorb CSF back into the bloodstream is normal. Thus, if a communication between the ventricle upstream from the site of the blockage and the subarachnoid space can be made, the hydrocephalus could be effectively treated. This is done by placing an endoscope into the lateral ventricle, and then under direct vision the tip of the device is guided into the third ventricle. The fluid within the ventricle can escape through the hole into the subarachnoid space and ultimately get absorbed back into the bloodstream through the normal pathways. In properly selected patients, about 80% can be effectively cured of the hydrocephalus by an ETV. The remaining 20% will need to be treated with a shunt.

  Chiari malformation treatment often involves surgery. The goal is to remove bone and “decompress” the area of the brain with pressure. That means opening the skin, retracting back the muscles, and then removing the bone shown here in yellow. This is often the back of the skull and the back of the c1 and/or C2 vertebrae (if needed). The skull bone removal procedure is called a posterior fossa decompression. […] Complications from this procedures are substantial. They include more than 1 in 10 of the patients having a dural leak. This means that the doctor cuts through the covering of the brain and spinal cord (the dura) which is the sac containing cerebrospinal fluid in which the brain floats. The dura is then sewn back up and leaks, often requiring another surgery. Other common complications include 9% who get an infection of the brain (meningitis), infected wounds at 7%, and damaged nerves in 5%. About 3% of the patients die from the surgery.

  However, a much bigger deal with this surgery, even beyond the very serious complications that could happen, is the collateral damage. To understand that, we need to review the critical anatomy in this area. In the image shown here, note that the PAOM is a ligament in the back of the neck that helps to keep the skull stable on the neck as you look down. Then note the myriad of muscles in the upper neck at the base of the skull. They’re responsible for maintaining your head stability on your neck.

  The only effective treatment for Chiari malformation is surgery. The most common surgical procedure is suboccipital craniectomy to decompress the cerebellar tonsils (surgical opening of the bony compartment of the back of the head) with laminectomy of C1 and/or C2 to decompress the cervical spinal cord. Opening of the dura (lining of the brain and spinal cord) with dural grafting to expand the cranial and upper cervical spine space completes the procedure. […] The recovery period requires a one-to-two-day stay in the intensive care unit for neurologic observation. This is followed by another one-to-three days in a general hospital room to complete hospital recovery and resume independent self-care activities. The total hospital stay averages three to five days. […] Outpatient recovery usually takes four to six weeks. During the first two weeks, no driving is allowed. A return to an office job or sedentary work can resume approximately four to six weeks after surgery. Full physical activity can be resumed in approximately two to three months.
