Classification of Otitis Media in Children< /> Chronic suppurative otitis media is a chronic suppurative inflammation of the middle ear mucosa, periosteum, or deep into the bone. It often coexists with chronic mastoiditis. This disease is extremely common. Clinically, it is characterized by repeated discharge of pus in the ear, perforation of the tympanic membrane and hearing loss. It can cause serious intracranial and extracranial complications and be life-threatening. < /> Bone ulcer type otitis media, also known as necrotizing otitis media or granulation type otitis media, is mostly delayed from acute necrotizing otitis media. The tissue destruction is extensive, and the lesions reach deep into the bone. Necrosis may occur in the tissues around the ossicles and sinus tympanum, and granulation tissue or polyps may form locally after the mucosal epithelium is destroyed. < />Cholesteatomatous otitis media and chronic suppurative otitis media are divided into three types. Cholesteatomatous otitis media belongs to the third type, which is also the most serious type of these three types of otitis media and is prone to complications. < /> In aviation otitis media, atmospheric pressure decreases with increasing altitude. During navigation, as the aircraft rises or lands, the air pressure in the cabin changes accordingly, and the gas in the air cavity expands or contracts accordingly. Generally, when the Eustachian tube ventilation function is good, when the aircraft is ascending and descending, through the adjustment of the Eustachian tube and artificial active ventilation actions, the pressure balance inside and outside the tympanic membrane can be maintained. At this time, there is only a feeling of ear distension or slight hearing impairment, but not Can cause ear damage. If the pressure inside and outside the middle ear cavity cannot be quickly balanced, various syndromes will occur, collectively called barotrauma, and damage to the middle ear cavity is called aviation otitis media. It can also occur during diving operations, hypobaric chamber work, and hyperbaric oxygen therapy.
Classification of otitis media in children Adhesive otitis media, adhesive otitis media is the proliferation or scarring of fibrous tissue in the middle ear, which is the result of previous inflammation of the middle ear. It often develops in childhood. < /> Serous otitis media, secretory otitis media, also known as serous otitis media, is the accumulation of exudate in the middle ear due to incomplete recovery of acute otitis media or obstruction of the Eustachian tube. Secretory otitis media is common in children. Exudate may be sterile, but often contain pathogenic bacteria. Eustachian tube obstruction can be caused by nasopharyngeal inflammation, allergies, adenoid hypertrophy, benign or malignant tumors.
