Middle Ear Effusions: Preliminary Viscometric, Histologic and Biochemical Studies

Physical and biochemical characterization of effusions in serous otitis media has been difficult because of the small amount of material available for analysis. The volumes usually available are in the range of 0.2 to 0.4 ml. Senturia-" recently proposed a classification which segregates various types of effusions according to their gross appearance and histology. The present work represents a preliminary attempt to extend the characterization of middle ear effusions by means of microviscosimetry, biochemical studies and histologic examination.
