There is still considerable difference of opinion as to the best technic to be followed, on the part of those who are called on to perform operations for abscess within the brain substance.
The otologist, who so often encounters intracranial suppuration as a complication of middle ear disease, usually, and I believe often inadvisably, makes the approach to the abscess by an extension of the incision of the mastoid operation, whether it is in a cerebellar hemisphere or in a temporal lobe. The surgeon, on the other hand, is more likely to expose the brain and to deal with the abscess through a separate opening in an aseptic field, well away from the wound of a former operation if such has been performed.
I shall not give the results of my operations for brain abscess, for in such a report the classifications of the patients would have to be considered,
