Macroscopic pathology may include considerable scar tissue that can result in blockage of the ear canal. Where this occurs cerumen and debris are often trapped inside. The tympanic membrane is often thickened. The ear canal and tympanic membrane will be acutely inflammed. This inflammation may progress to the inner ear and/or meninges.
