Otitis media is an inflammatory lesion that affects all or part of the middle ear, including the eustachian tube, tympanic cavity, tympanic sinus, and mastoid air chamber.
It can be divided into two categories: non-suppurative and suppurative. Non-suppurative cases include secretory otitis media, air pressure injury otitis media, etc. Suppurative cases are acute and chronic. Specific inflammation is too rare, such as tuberculous otitis media.
clinical picture
Otitis media suppurative
(1) Acute suppurative otitis media
Inflammation of the middle ear caused by suppurative bacterial infection, the main symptoms are ear pain, discharge of pus. Children's systemic symptoms are more obvious than adults, including fever, vomiting and so on. Serious complications include intracranial complications, such as meningitis, brain abscess and so on. Other complications include labyrinthitis and facial nerve paralysis.
(2) Chronic suppurative otitis media
It refers to the middle ear mucosa, periosteum or bone deep chronic suppurative inflammation. This disease is more common in clinical practice, often intermittent or persistent intraear pus, tympanic membrane perforation, hearing loss as the main clinical manifestations, severe can cause intracranial and extracranial complications.
① Systemic symptoms
The weight varies. May be afraid of cold, fever, fatigue, loss of appetite. Children with severe systemic symptoms, often accompanied by vomiting, diarrhea and other gastrointestinal symptoms. Once the eardrum is perforated, the body temperature gradually drops, and the systemic symptoms are significantly reduced.
② earache
Deep ear pain, gradually increasing. Pulsating pain or tingling may radiate to the ipsilateral head or teeth. Ear pain worsens when swallowing and coughing, and people with severe ear pain can not sleep at night and become agitated. The ear pain decreased after the perforation of the tympanic membrane and discharge of pus.
③ Ear discharge
It is the main symptom of the disease and can be mucous, viscous or pure purulent. Non-dangerous discharge is thinner and odorless. Although the dangerous type of pus flow is not much, but more thick, mostly pure pus, and accompanied by odor.④ Hearing loss and tinnitus
The ears begin to feel stuffy, followed by hearing decline, accompanied by tinnitus. Deafness can be ignored if the earache is severe. Some patients may be accompanied by vertigo, deafness after perforation but reduced.
⑤ Deafness
The severity is different, because most of them are single-ear disease, easy to be ignored. It is usually conductive deafness.
