Otitis Externa is the generalised inflammation of the skin of the external auditory meatus. It may be acute or chronic.
In this condition the external meatus looks markedly congested and inflamed. There is some amount of purulent discharge. The condition is painful and pinna is tender to touch. There may be a rise of temperature.
In Chronic Otitis Externa the skin does not look very much inflamed but it may be thickened. Other signs and symptoms are as for the acute stage but less marked.
