In this study we postulated that periosteoma soft tissues display interrupted early stages of osteoma formation, which could help us to understand the chronology as well as the mechanism of osteoma formation.
Because aspiration of cortical tissue may interrupt fibres of passage moving through the cortical region en route to their destination, the prefrontal lesions were produced via injections of excitotoxin rather than by subpial aspiration of grey matter.
In this procedure, the surgeon makes a series of shallow cuts on your child's brain tissue to interrupt any seizure impulses but does not harm their normal brain activity.
