callosectomy
Noun: A surgical procedure that involves the severing of the corpus callosum, the bundle of nerve fibers connecting the two hemispheres of the brain. This operation is performed to interrupt communication between the cerebral hemispheres, primarily as a treatment for severe and intractable epilepsy that does not respond to medication.
The term is used in medical and neuroscientific contexts to describe a specific type of brain surgery. * The patient underwent a callosectomy to reduce the frequency of debilitating seizures. * A callosectomy is considered only after multiple anti-epileptic drugs have failed.
- Complete vs. Partial Callosectomy: The procedure can involve cutting the entire corpus callosum (complete) or only a portion of it (partial), depending on the clinical assessment.
- The neurosurgeon recommended a partial callosectomy to mitigate risks.
- Corpus Callosotomy: This is the more common clinical synonym for callosectomy. Both terms refer to the same surgical procedure.
- Corpus callosotomy is another name for this intervention.
- Corpus Callosotomy: The splitting or cutting of the corpus callosum.
- Split-brain surgery: A more general, descriptive term for the procedure and its resulting condition.
The primary and singular meaning of "callosectomy" is the surgical procedure described above. It is a highly specialized medical term with no idiomatic or colloquial uses. The goal of the surgery is to prevent seizure activity from spreading from one brain hemisphere to the other.
- severing the corpus callosum so that communication between the cerebral hemispheres is interrupted (in cases of severe intractable epilepsy)
