L’otite esterna acuta: dalla diagnosi al trattamento

Acute otitis externa (OEA) is an infectious of the external auditory canal with peak inci- dence between 5 and 9 years. Predisposing factors are the summer period, water sports and duct injuries (e.g. cotton buds). The diagnosis is clinical and the responsible agents are mainly bacteria (Pseudomonas aeruginosa followed by Staphylococcus aureus). The therapy involves the local use of acidifiers and/or antiseptics for mild forms while for moderate forms topical antibiotics (in monotherapy or in combination with cortisone and/or anaesthetics). The use of systemic antibiotics should be reserved only for severe forms or those not responsive to topical therapy.
