Which of the following treatments is most indicated for Eustachian tube dysfunction?

Nasal corticosteroids are particularly effective in treating Eustachian tube dysfunction because they help reduce inflammation and swelling in the nasal passages and Eustachian tube, thus promoting drainage and improving tube function. The condition often arises due to allergies, sinus infections, or other inflammatory processes, where relieving inflammation can restore normal function of the Eustachian tube.

Nasal corticosteroids can significantly alleviate symptoms by decreasing nasal congestion and improving airflow, which is crucial for equalizing pressure in the middle ear. This makes them a preferred treatment choice in managing Eustachian tube dysfunction related to allergic rhinitis or upper respiratory infections.

Other treatments listed may not address the underlying problems of Eustachian tube dysfunction effectively. For example, while oral antibiotics can be useful in treating bacterial infections, they are not appropriate for dysfunctional cases particularly without evidence of an infection. Antihistamines may help in some cases, but they can also dry up mucus and potentially worsen congestion in the long run. Hot compresses could provide temporary relief but do not address the underlying causes or contribute to resolving the dysfunction effectively. Therefore, nasal corticosteroids represent the most suitable and evidence-backed option for this condition.
