The article analyzes the concept of lobotomy in Norwegian psychiatry. According to the annual reports of the various medical institutions, lobotomies in Norway were usually performed in psychiatric hospitals rather than in the neurosurgical wards of general hospitals, as in Sweden and Denmark. Norway's geography may explain this difference. Indeed, transportation to centrally located hospitals with neurosurgical departments is more difficult than in either Denmark or Sweden. Because of this problem, itinerant surgeons with no training in neurosurgery often performed the operations.

We conducted a retrospective longitudinal self-controlled study of 124 adult patients treated with resective surgery for medically uncontrolled partial epilepsy from 1949 to 1988. Approximately 65% of the patients experienced > 95% reduction in seizure frequency, and 75% had worthwhile improvement of at least 75% seizure reduction. Significant reductions were noted in all major seizure types treatable with resective surgery; complex partial (CPS), simple partial (SPS), and secondarily generalized tonic-clonic seizures (GTC) (all p < 0.05). Tissue pathology and region of resection did not provide significant information with respect to seizure outcome. EEG in the first postoperative year was an important predictor of long-term seizure outcome (p = 0.03). One third of the temporal lobe resected patients had neurologic deficits as a consequence of the resection as compared with 14% of patients with frontal resections (p = 0.03). One third of the deficits among the temporal lobe resected patients were considerable, with possible social implications. Half of the patients with preoperative focal spike activity had a normal EEG postoperatively. One fifth of patients maintained their preoperative epileptic focus after the operation, and about one fifth displayed new foci. Approximately one fourth of the patients were free of medication for a median of 16 years postoperatively, and 60% of patients who were seizure-free were still receiving medication. There was no operative mortality, but the late mortality, as expected, was higher than that of the general population. Two male patients (1.6%) committed suicide.

We conducted a retrospective longitudinal self-controlled study of 64 patients aged 4-19 years treated with resective surgery for partial epilepsy from 1952 to 1988. Approximately 60% of patients experienced > 95% reduction in seizure frequency, and 70% had worthwhile improvement of at least 75% reduction. Seizure relief was more frequent among patients who underwent operation after 1978, and significant differences by time period of operation were noted for those with temporal lobe excisions and patients with normal tissue histology. The region of resection and the age at treatment did not provide significant information with respect to seizure outcome. Postresection electrocorticography (ECoG) and EEG of the first postoperative year predicted later seizure outcome. Small neurologic deficits were more common among patients resected in the temporal lobe than in patients resected in the frontal lobe. Half of the patients with preoperative unilateral focal activity and a third of those with bilateral focal activity had normal EEG postoperatively. One fourth had discontinued antiepileptic drug (AED) therapy. As expected, long-term mortality was significantly higher than the mortality of the general population. Seven patients died during follow-up. Two male patients committed suicide.
