Purulent otitis media in children and adults.
This study was designed to compare tympanic membrane (TM) and middle ear (ME) pathologies of temporal bones from children and adults with purulent otitis media (POM). Thirty-four temporal bones were used from 22 subjects ages 2 days to 76 years with histopathologic evidence of POM. There were 55 age-matched controls. Histopathologic findings of the TM and ME in children and adults with POM were compared. Clinical histories and the presence of complications were recorded. The incidence of POM was more common in male children than in females. There was a significant increase in the thickness of the posterosuperior and posteroinferior quadrants in children with POM compared to non-OM children. In adults with POM, there was a significant decrease in the thickness of the posteroinferior and anteroinferior quadrants compared to non-OM adults. Children with POM showed a significant increase in the anterioinferior and posteroinferior quadrants and the umbo compared to adults with POM. Pathology of the TM and ME occurred in adults and children, but severity was greater in children. Residual mesenchyme was frequently observed in temporal bones of children. Serious complications such as labyrinthtis and meningitis were observed more frequently in children. All cases with meningitis had labyrinthitis, previous histories of otitis media and had been treated with antibiotics. Although POM occurs in both children and adults, pathologic changes of the middle ear are more severe, and complications (labyrinthitis and meningitis) occur more often in children. Our findings suggest the need to monitor children carefully under the age of 2 years who have POM.
