145: Intracranial Complications of Chronic Otitis Media

Abstract

sule is defined pathologically as a thick enveloping layer of connective tissue that is both microscopically and macroscopically evident, it must be concluded that ANs are nonencapsulated, at least in the conventional sense of the term. The surface peel observed intraoperatively is most likely surgically created during tumor debulking by cleaving the looser central component from the more compressed portion that lies immediately beneath the free margin of the lesion.
