Ear pus is very common clinically! It must depend on the source, is it otitis externa of external ear canal origin, eczema of the external ear canal or is there inflammation of the middle ear? Inflammation of the external ear canal can often be cured by drops and oral medication, while inflammation of the middle ear often requires surgery if it is chronic. In the case of pus in the middle ear, it is recommended that you do not blow on powdered medication, as that can easily cause poor flow of pus and crusting in the ear. You can choose to alternate ear drops with hydrogen peroxide and antibiotic ear drops with antibiotic treatment. If this treatment results in repeated episodes of pus flow and poor hearing, it is recommended to choose the right time to go to a major hospital for examination and check if there are hidden lesions in these parts of the upper tympanic chamber and mastoid process that need to be cleared according to the middle ear CT. These lesions are not visible from the external ear canal, but if they exist and are not cleaned, they can become inflamed and flow pus repeatedly. In this case, surgical treatment is required.
