From a Western medical point of view, there is no such thing as “hairy” food, such as fish or eggs, beef, lamb, etc. Patients with otitis externa can eat eggs. Eggs are high-protein foods that can strengthen the body’s resistance and help patients recover from their condition. However, it is recommended that patients eat boiled eggs, avoid overly greasy food, and do not eat fried eggs. Patients can use levofloxacin hydrochloride ear drops or ciprofloxacin ear drops to treat the condition. If necessary, oral antibiotics such as cefprozil tablets can also be added, and the allergy history should be clarified before using the medicine.
