Acute Otitis Media and a major cause of clinical manifestations what?

Bacteria enter through certain channels from the middle ear mucosa of the middle ear infection known as acute suppurative acute suppurative otitis media. A hemolytic streptococcus bacteria, Staphylococcus aureus, Streptococcus pneumoniae and Proteus see more. Because of the mouth and pharynx children eustachian tube drum mouth position almost the same level, Eustachian tube and shorter diameter coarse, so common in children with this disease. If not timely and effective treatment, easily cause acute suppurative otitis media or deferred for chronic suppurative otitis media, and even outside of intracranial complications, it should be much attention.
Body resistance decreased if nutrition obstacles, cold or wet, known as systemic chronic> allergic diseases and sexually transmitted diseases> diseases, the incentives from the disease. Pathogens enter the middle ear channel is: (1) eustachian tube ways: ① acute upper respiratory tract infection, germs and more through the eustachian tube into the middle ear. ② acute infectious diseases, particularly the incidence of measles and scarlet fever, the disease may be complicated. ③ breastfeeding posture misconduct, such as babies, infants or supine sucking bottles, milk Book of Changes eustachian tube into the middle ear. ④ excessive force blow nose nose in the dirty water swimming and diving, Zhang inappropriate blowing of the eustachian tube and flushing of the nasal cavity, the bacteria can enter the middle ear through the eustachian tube. ⑤ acute otitis media with effusion, if invasive bacteria can develop into acute suppurative otitis media. (2) external ear way: As the tympanic membrane rupture, the bacteria enter the middle ear ruptured eardrum, causing infections. (3) Blood Bank: pathogenic bacteria enter through the blood circulation caused by inflammation of the middle ear Although fewer opportunities, but its tympanic membrane lesions often cause necrosis. More common in scarlet fever and typhoid.
Acute Otitis Media pathological changes limited to the mucosa showed congestion, edema, and a round cell infiltration, epithelial necrosis. Exudates from purulent-graded for the visco-final was pure purulent. As drum outdoor empyema, the pressure increased, oppression tympanic membrane, or eardrum itself because of inflammation in violation of softening or between layers abscess, the end of the tympanic membrane rupture, the pus in the middle ear to ear canal can be draining. Because of the continuity of the middle ear structure, papillary lesions often extended to the gas, can be re-developed into acute suppurative otitis media.
The acute suppurative otitis media in the main symptoms of eardrum perforation and inspection before and after the very different, reflected in the following aspects: (1) systemic symptoms: eardrum perforation, systemic fever,fatigue and other symptoms more pronounced. Many children with vomiting, diarrhea and other symptoms of acute gastroenteritis. Before the tympanic membrane perforation deep sharp ear pain or tingling and pain may amount of radiation to the Department of ipsilateral, temporal, teeth, the result of the tympanic membrane on the trigeminal nerve branches (of the external auditory canal auriculotemporal sticks) reflection of the company. Infants often crying in the unrest, antifeedant. When the eardrum perforation or through spontaneous incision, and other processing to pus discharge, pain drop, systemic symptoms has also improved. (2) deafness and tinnitus: before flu ear fullness, following the hearing gradually descending, with tinnitus. Instead reduce deafness after perforation. Sometimes with vertigo. (3) Excess septic ear: perforated eardrum after the outflow of ears with pus, initial blood, after White Nien thick pus or yellow pus. (4) ear examination: the initial relaxation of the tympanic membrane congestive, hammer handle and tension of the bone surrounding the foreseeable radial expansion vascular; followed tympanic membrane showed diffuse congestion, with swelling outward such as papilloma, a yellow center point. The beginning of tympanic membrane perforation, perforation of small, perforated eardrum after the removal of pus that the scintillation pulse points, or see it with pus outflow. (5) hearing tests:-tone deafness show. Perforation after hearing improved. (6) palpation examination: because of the inflammatory response mastoid periosteum, the mastoid tip may have tenderness. After the tympanic membrane perforation gradually disappear.
