Normally, everyone has a bone protruding from the back of the ear, medically known as the mastoid process. This is the part of the ear that is composed of the mastoid with the air chamber containing the air inside. In cases of chronic suppurative otitis media or acute inflammation, this can cause an infection in this location, clinically known as middle ear mastoiditis. In terms of treatment, the main thing is to use antibiotics symptomatically, and cephalosporin anti-inflammatory drug infusions can be chosen for treatment. Localized ear drops, such as Telbital ear drops, should be used topically. If there is a lot of purulent discharge, it is also necessary to use hydrogen peroxide to cleanse and then apply medication. Some patients with middle ear mastoiditis who do not respond well to conservative treatment are also prone to intracranial infections, so they need to opt for surgical treatment and have mastoid radical surgery to remove the lesion and resolve the symptoms.
