I suspect William that your description of the surgery as being radical and invasive is based upon preconceptions from yesteryear - and procedure which breaks the skin, is after all, invasive and I am not sure something which is now in excess of 60 years old could still be called 'radical'. But I do take your point
This procedure is carried out now only very rarely and is used to enhance quality of life rather than as before, as a means to control symptoms. The area targeted within the brain is much more specific - rather than the wholesale destruction of matter previously carried out with frontal lobotomies. In the UK it is used (I have been out of psychiatry for 16 years so things may have changed - but it remains still a treatment option) only for very severe, non-responsive depression and OCD. My memory is patchy but I am not sure that clinical evidence suggested many positive outcomes for this desperate group - I could be wrong. Informed patient consent had to be given
Since the introduction of lobotomies in the 50s, there have been many significant improvements to more efficacious, cleaner drug treatments and also the development of other therapeutic interventions such as cognitive behavioural therapy. These breakthroughs have seen a proportionate decline in the need for the very old incarceration and surgical approach, fewer institutions and many more sufferers successfully re-integrated into the community
Beyond my limited info here...get Googling if you are looking for a nearby surgeon!!!
