As a result, new operative procedures have been pointed out and made possible in that region. During the same period intracranial lesions of aural origin have been rendered more accessible by improved operative methods. The new edition of this standard work gives the results of the investigations of Politzer and his followers in these new fields, as well as a revision of those subjects made necessary by the recent advancement in the pathology and therapeutics of aural affections in general. The addition of this new material again places a work of inestimable value in the hands of students of otology.
