What is typically the first-line treatment for otitis externa?

1. Oral antibiotics

2. Topical corticosteroids

3. Polymyxin and neomycin ear drops

4. Warm compresses

The correct answer is: Polymyxin and neomycin ear drops

The first-line treatment for otitis externa is typically the use of topical agents, particularly antibiotics. Polymyxin and neomycin ear drops are specifically formulated to target the bacterial infection that characterizes otitis externa, effectively reducing inflammation and eradicating the pathogens involved. Topical antibiotics like polymyxin and neomycin are favored because they deliver medication directly to the affected area, enabling higher concentrations of the drug where it is needed most, while also minimizing systemic side effects that can occur with oral antibiotics. This localized treatment is crucial in managing the symptoms and facilitating faster recovery. Other options, such as oral antibiotics, are usually reserved for more severe cases or when there are complications. Topical corticosteroids might be utilized to reduce swelling and inflammation, but they are not the primary choice in combating the infection itself. Warm compresses may provide symptom relief but do not address the underlying infection. Therefore, using polymyxin and neomycin ear drops aligns with the primary goal of treating otitis externa efficiently and effectively.
