They postulate that the incidence of intracranial abscesses secondary to orbital and paranasal sinus infections appears to be on the increase compared with those of otogenic origin. Great progress has been made in patient care and surgical techniques in the fields of Otolaryngology—Head and neck surgery, neurosurgery, ophthalmology, and neurosurgery and infectious disease therapy.

The primary sources of infection were treated surgically, but
