When should antibiotics be given for otitis externa?
Oral antibiotics are rarely needed 2 but should be used when otitis externa is persistent, when associated otitis media may be present or when local or systemic spread has occurred. The latter should be suspected if the patient's temperature is higher than 38.3°C (101.0°F), if initial pain is severe or if regional lymphadenopathy of the preauricular or anterior or posterior cervical chains is present. 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. Finally, consideration also should be given to starting oral antibiotics early in patients whose immunity may be compromised, such as those with diabetes, those taking systemic corticosteroids or those with an underlying chronic dermatitis. 5, 17, 21, 22

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.
Where do lesions occur in the body?
Lesions typically occur in the external auditory canal and elsewhere on the body, especially the head and neck. There is often a family history and a recurrent course. A thorough dermatologic examination and history should always be part of the evaluation of patients with otitis externa.
