Antibiotic therapy and surgery are common remedies for removing fluid buildup behind the eardrum. Fever and discomfort often accompany inner ear fluid retention and are symptoms of infection, according to Mayo Clinic.
Antibiotics are the first course of treatment for ear fluid, but they don’t always provide a cure, notes WebMD. When the condition persists, doctors may recommend a myringotomy. This surgical procedure drains fluid from the middle ear by placing tubes through small eardrum incisions. The tubes may remain in place for up to a year. Once the tubes are removed, the eardrum usually closes up on its own.
