What Happens After a Corpus Collosotomy?

The patient generally stays in the hospital for two to four days. Most people having a corpus callosotomy will be able to return to their normal activities, including work or school, in six to eight weeks after surgery. The hair over the incision will grow back and hide the surgical scar. The person will continue taking antiseizure drugs.

How Effective Is a Corpus Callosotomy?

Corpus callosotomy is successful in stopping drop attacks, or atonic seizures in which a person suddenly loses muscle tone and falls to the ground, in about 50% to 75% of cases. This can decrease the risk of injury and improve the person's quality of life.

What Are the Side Effects of Corpus Collosotomy?

The following symptoms may occur after having a corpus collosotomy, although they generally go away on their own:

  • Scalp numbness
  • Nausea
  • Feeling tired or depressed
  • Headaches
  • Difficulty speaking, remembering things, or finding words
  • Paralysis, weakness, loss of sensation
  • Change in personality

What Are the Risks of a Corpus Callosotomy?

Serious problems are uncommon with a corpus callosotomy, but there are risks, including:

  • Risks associated with surgery, including infection, bleeding, and an allergic reaction to anesthesia
  • Swelling in the brain
  • Lack of awareness of one side of the body
  • Loss of coordination
  • Problems with speech, such as stuttering
  • Increase in partial seizures (occurring on one side of the brain)
  • Stroke
