“…There have been a few descriptions of the effects of carotid ligation on aneurysm induced palsies (Jefferson, 1967;Hamilton and Falconer, 1959;Cantu, 1969;Hepler and Cantu, 1969;Raja, 1972) and brief mention of the results after direct intracranial approach to the aneurysm (Jaeger, 1950;Henderson, 1955;Harris and Udvarhelyi, 1957;Botterell et al, 1962;Johnston and Pratt-Johnson, 1963), but in many of these cases it is impossible to correlate the site of the aneurysm with the type of treatment carried out. Jefferson (1947) found that the palsy never recovered fully, but Jaeger (1950) stated that, even if the third nerve were seriously withered by pressure, it could still recover completely.…”
