Otitis media is a common ear disease that is divided into two types: acute and chronic, each of which is classified as either cicatricial or purulent. Acute cicatricial otitis media is a lesion of the tympanic chamber secondary to acute obstruction of the eustachian tube, which can become chronic with incomplete treatment; acute suppurative otitis media is caused by the invasion of septic bacteria into the tympanic chamber, which can easily become chronic or complicated by acute mastoiditis if not treated properly or in poor general condition. Pathologically, the main lesion of catarrhal otitis media is mucosal congestion and edema with increased exudation, while chronic otitis media can eventually form scar adhesions. Septic otitis media has inflammatory features with perforation of the periosteum. Depending on the pathological changes, the chronic stage can be divided into simple and purulent otitis media, osteoma type and cholesteatoma. Clinical changes] In acute otitis media, there is swelling and pain in the ear, tinnitus and vertigo, accompanied by systemic symptoms, and if the periosteum is perforated, plasma or plasma thick secretions flow out. In the chronic stage, it becomes persistent or intermittent pus flow and hearing loss. 【Treatment】Drugs to control local exudation and congestion; anti-inflammatory; surgical treatment, etc. Physical therapy: 1, semiconductor laser treatment: low intensity laser can well improve the human immune function, directly enhance the local tissue anti-infection ability; make local vasodilation, accelerate blood circulation; accelerate the repair of broken tissue; but also has a strong antibacterial effect. At the same time, it also avoids the toxic side effects brought by drugs to the whole body. 2, five official ultrashort wave therapy: ultrashort wave therapy can act domain deep tissue, improve blood and lymph circulation, so that local leukocytes and antibodies increase, accelerate the dissipation of inflammation; at the same time, it can make leukocytes and macrophages phagocytosis; electric field itself to inflammatory cells caused a bad living environment, directly inhibit the reproduction of inflammatory cells. Early physical therapy can effectively stop the deterioration of the disease, relieve the spread of inflammation and eliminate the lesions; if the tympanic membrane perforation has occurred and surgery is required, physical therapy during the perioperative period can avoid the occurrence and spread of infection, increase the success rate of surgery and significantly reduce the rate of postoperative infection and recurrence.
