中耳

The 46 ears classify into three groups on the basis of hearing threshold level,and classified into four groups on the basis of different disorders.Results The amplitude and reproducilbiity decreased as the hearing loss increased.

选择经耳镜检查、纯音听阈及声导抗测试确诊为中耳病变，纯音气导听阈不超过30 dB HL的46只病变耳及对照组正常28耳进行TEOAE测试，病变46耳分别按不同听阈水平及不同病变分组，并对其结果进行分析比较。

In more complex ears, the tympanic membrane transmits information to the middle ear.

Abstract］ Objective To study the value of CT scan in diagnosing tympanic cholesteatoma.

目的 研究CT对中耳胆脂瘤的诊断价值。

MethodsThe facial nerve canal CPR images of 83 cases of cholesteatomtaous tympanitis confirmed pathologically were retrospectively analyzed.

回顾分析经手术病理证实的83例胆脂瘤型中耳乳突炎患者面神经管曲面重组表现。

ObjectiveTo explore the clinical application value of 64-slice spical CT curved multiplanar reformation of the facial nerve canal in cholesteatomtaous tympanitis.

小 目的探讨64层螺旋CT面神经管曲面重组在胆脂瘤型中耳乳突炎中的应用价值。

No matter whether there is a tympanic membrane perforation or not, secret tympanitis should be subjected to surgical treatment at an early stage.

若按早期中耳炎治疗病情不能稳定甚至加重，并经CT证实中耳乳突腔有填塞表现者，无论是否有鼓膜穿孔，均应行早期外科手术干预。

To measure structures of the posterior tympanum and thus to provide theoretical reference for operation approach related to the middle ear.

目的通过研究后鼓室有关解剖结构，及对后鼓室入路手术的径路进行观察、测量，为中耳相关手术入路提供理论参考依据。

The result showed that the pathological changes in the tympanum implanted with the nickel-titanium scaffold were slight as compared with those of the silatic film. This might be related the proping action of the scaffold and being benefit of ventilation and clearance of the middle ear.

结果发现，镍钛支架鼓室内植入出现的病理变化普通较硅片植入耳轻，这可能同支架的支撑作用和便于中耳通气和清除有关；但病变并未清除。

The fibrous capsulae were formed. From the exudate to the collagenous fibrous hyperplasia stage the inflammatory cells were gradually decreased, while the fibroblasts were constantly increased in the pathological tissue of the middle ear.

从渗出期到胶元纤维增生期，中耳病变组织中炎细胞逐渐减少，炎性渗出物逐渐消散，而纤维母细胞始终增生明显。

Objective:To study the state of proliferation and apoptotic cell death in cholesteatoma.

目的 ：研究中耳胆脂瘤上皮细胞增生和凋亡的状态。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
