Acute suppurative otitis media often appears after acute upper respiratory tract infections and is more common in pediatric patients. Treatment can be divided into three stages. The main symptoms in the early stage of the disease are ear pain and ear stuffiness, accompanied by mild hearing loss or even tinnitus, and children patients may also have fever and flu. The main treatment measures during this period are oral antibiotics and nasal application of drugs to reduce the swelling of the eustachian tube and improve its function. Three to five days after the onset of the disease, the ears may become dripping with pus. During this period, in addition to the basic treatment described above, the outer ear canal should be cleaned with hydrogen peroxide and ear drops containing antibiotics should be applied. If the symptoms are not significantly relieved or even worsened after about 3 days of the above treatment, such as severe pain and redness around the ear, this indicates that the middle ear infection has caused pus to form and to be retained in the mastoid cavity of the middle ear. In this case, surgical intervention is required. Depending on the case, either tympanotomy or mastoidectomy can be chosen.
