Otitis media should be considered when the patient has had an upper respiratory infection or is younger than two years, an age when otitis externa is uncommon. Systemic antibiotics also should be considered when the patient has even early signs of necrotizing otitis externa, as described later.

What is the external auditory canal?
The unique structure of the external auditory canal contributes to the development of otitis externa ( Figure 1). It is the only skin-lined cul-de-sac in the human body. The external auditory canal is warm, dark and prone to becoming moist, making it an excellent environment for bacterial and fungal growth. The skin is very thin and the lateral third overlies cartilage, while the rest has a base of bone. The canal is easily traumatized. The exit of debris, secretions and foreign bodies is impeded by a curve at the junction of the cartilage and bone. The presence of hair, especially the thicker hair common in older men, can be a further impediment.

If inflammation causes sufficient swelling to occlude the external auditory canal, the patient may also complain of aural fullness and loss of hearing. 6 – 8 Otorrhea is also quite variable. Its characteristics often may give a clue to its etiology ( Table 2). 4, 6, 9 – 11
