Hemispherectomy is a surgery that is performed by a neurosurgeon where an unhealthy hemisphere of the brain is disconnected or removed. There are two types of hemispherectomy. Functional hemispherectomy refers to when the diseased brain is simply disconnected so that it can no longer send signals to the rest of the brain and body.
Recovery after ATL can take several weeks to months. Anti-seizure medications will be continued for several months after ATL. As it is an open surgery it takes time for the brain to heal. [10] Speech therapy, occupational therapy, etc. can help recovery. About 90% of people experience an improvement in seizures after temporal lobectomy.
Bilateral procedures are poorly tolerated because of increased complications and risk, including vision and speech problems. The positive effects on tremors are immediate. Other less destructive procedures are sometimes preferred, such as subthalamic deep brain stimulation, since this procedure can also improve tremors and other symptoms of PD.
Pain following brain surgery can be significant and may lengthen recovery, increase the amount of time a person stays in the hospital following surgery, and increase the risk of complications following surgery. [50] Severe acute pain following brain surgery may also increase the risk of a person developing a chronic post-craniotomy headache. [50]
The risk of POCD increases with age, and the type of surgery is also important because there is a very low incidence associated with minor surgery. [4] POCD is common in adult patients of all ages at hospital discharge after major noncardiac surgery, but only the elderly (aged 60 years or older) are at significant risk for long-term cognitive ...
A craniotomy is a surgical operation in which a bone flap is temporarily removed from the skull to access the brain.Craniotomies are often critical operations, performed on patients who are suffering from brain lesions, such as tumors, blood clots, removal of foreign bodies such as bullets, or traumatic brain injury, and can also allow doctors to surgically implant devices, such as deep brain ...
Outcomes for each type of surgery vary widely depending on seizure localization, epilepsy specifics, and surgeon approach. Given that this is a new technique, more research into comparing outcomes is necessary but preliminary studies suggest lower seizure freedom. [39] [48] [49] See also ablative brain surgery. [50]
Decompressive craniectomy (crani-+ -ectomy) is a neurosurgical procedure in which part of the skull is removed to allow a swelling or herniating brain room to expand without being squeezed. It is performed on victims of traumatic brain injury, stroke, Chiari malformation, and other conditions associated with raised intracranial pressure. Use of ...
