Treatment: 1, active treatment of upper respiratory tract focal diseases such as chronic sinusitis, chronic tonsillitis. 2.Medication The simple type is mainly local medication. Aqueous antibiotic solution or a mixture of antibiotics and steroid hormone drugs, such as 0.25% chloramphenicol solution, chloramphenicol cortisone solution, oxyfloxacin ear drops, etc., can be used to treat otitis media and otitis externa. (1) Clean the pus in the external ear canal and middle ear cavity before using the medication, and use 3% hydrogen peroxide or boric acid water to clean it. (2) When the amount of pus is large, use water, and when the amount is small, use boric acid alcohol. 4. If a large tympanic membrane perforation affects hearing, tympanic membrane repair or tympanoplasty is feasible. Many ear patients who have undergone ear surgery often attach great importance to the surgery, but do not understand the post-operative follow-up, which often prevents the disease from being completely treated and leads to treatment failure and the need for another surgery. Most ear diseases are prone to recurrence, especially cholesteatoma of the middle ear, but if one insists on post-operative follow-up with good surgical quality, the chances of recurrence are very low. In order to reduce recurrence of the disease, in addition to successful ear microsurgery, post-operative follow-up is very important. Therefore, it is necessary to have regular follow-ups with the doctor, who will guide the medication according to the condition of the operated cavity and promptly clean the diseased tissue to promote early epithelialization of the operated cavity, thus reducing recurrence and achieving a cure. The first follow-up is usually 2 weeks after surgery, and about 1 month after surgery this doctor will perform a thorough cleaning of the surgical cavity, and will guide the change of medication or spot medication according to the condition of the surgical cavity until the wound heals. Then, the follow-up is usually once a month for the first six months, once every 2-3 months for the second six months, and once every six months thereafter.
