People suffer from petit mal.which surgery removes the tissue.and which area are the seizures coming from.

Seizure surgeries: The term "petit mal" is really not used any more. Those seizure types are called "absence" or "complex partial" seizures. The surgery to remove the seizure focus/foci requires localization on the cortex using an EEG (electroencephalogram) and often intraoperative mapping. Very specific to each patient. Before you agree to surgery, consider adding adjunct meds and/or VNS to your monotherapy first.

Absence seizures, : formerly petit mal seizures, often start in early childhood & stop before age 20. If they start ~age 10, they may persist, but often as complex partial or tonic-clonic seizures. Absence EEG spikes-&_waves may be generalized in kids. Adult focal seizures refractory to AED's are more likely to be complex partial seizures. Tests to define type & area of genesis of seizures are available.
