Otitis externa, an inflammation of the external auditory canal is the most frequent cause of ENT consultation all over the world. It can be caused by viral, bacterial or fungal infections. In most of the cases it is provoked by anatomical causes and, even more frequently inadvertently, by the patient himself. Typically, otitis externa is an isolated episode of short duration, easily treated with topical medication. It evolves rarely to the atypical forms of chronic otitis externa and malignant otitis externa. It is important to search for an allergy, eczema or immunodepression in cases of chronic otitis externa and for diabetes in cases of malignant otitis externa.

Topical antibiotics are frequently introduced in therapy by various specialists, e.g., dermatologists-venereologists, ENT specialists, proctologists, ophthalmologists, and others. In dermatology, topical antibiotics are used in the treatment of superficial inflammatory skin lesions, acne and rosacea. These agents are also used in the prevention of inflammatory lesions after surgical and corrective procedures. Long-term and uncontrolled application of topical antibiotics, on the skin with impaired protective barrier in particular, implies a risk for the development of hypersensitivity to these agents. Considering the very wide utilization of these agents, hypersensitivity to topical antibiotics poses a major problem worldwide. The groups at a high risk of contact sensitivity to topical antibiotics include patients with chronic venous insufficiency, chronic ulcers and chronic otitis externa, as well as individuals at occupational exposure to antibiotics, e.g., human medicine and veterinary medicine professionals, pharmaceutical industry workers, cattle breeders, etc. When long-term therapy fails to result in improvement in the above mentioned chronic states, the possibility of allergic reactions to topical agents should be taken in consideration. Cross-sensitivity, which is frequently associated with the use of topical aminoglycoside antibiotics, poses a significant problem.
