We collected 11 cases with intractable secretory otitis media from february 1990 to september 1993 从1990年2月到1993年9月，共选择11名顽固性分泌性中耳的病例。
The bacteria that cause middle ear infections , streptococcus pneumoniae , aren ' t transmitted at school 引起中耳感染的细菌，如：肺炎链球菌，并不是在学校被传播的。
In november 1992 , we encoun - tered a 35 - year - old woman patient with otogenic meningitis 脑膜或脑组织脱垂至中耳或乳突部位极为少见，多为中耳手术后造成骨缺损而导致。
Expression of bone morphogenetic protein in middle ear mucosa of the guinea pig with chronic suppurative otitis media 骨形成蛋白在慢性化脓性中耳炎豚鼠中耳粘膜的表达
The aim of this study is to ascertain the influence of children ' s middle ear diseases on dpoae 为探讨儿童中耳疾病对于变频耳声传射检查结果的影响，我们做了以下的研究。
Well , aero - otitis is simply caused by the sudden imbalance of the air pressure inside and outside the middle ear 好，航空性耳炎是由于中耳内外的压力骤然失去平衡造成的。
On descent , the air in the middle ears is reduced in volume by the increasing surrounding ( ambient ) pressure 在下潜的时候，中耳部的空气由于周边环境的压力加大而体积减少。
There is impairment in sound transmission from the inner ear to the brain and the central nervous system 主要是由于外耳或中耳部份出现毛病，引致声波不能由外耳道传送到内耳部份。
For bacterial complications such as pneumonia , sinusitis or middle ear infection , antibiotics may be needed 如有因细菌引起的并发症，例如肺炎窦炎或中耳感染，患者或须服用抗生素。
Meanwhile , the pass rate decreased as the middle ear negative pressure became more aggravated ( 2 = 13 . 49 , p < 0 . 05 ) 以上中耳疾病造成变频耳声传射检查通过率的下降，具有统计学上的意义。
