The tympanogram was A-type curves in the acoustic immitance test, and acoustic stapedius reflex was normal.

声导抗测试鼓室导抗图为A型，交叉和非交叉镫骨肌声反射均可引出。

Methods Acoustic immitance determination including tympanogram and stapedius muscle reflex were performed with enhancement type middle ear analyzer-Madsen ZODIAC901 in 200 children with secretory otitis media before and after treatment. Psychological care was well done in sick children and their relatives.

用Madsen ZODIAC901增强型中耳分析仪对200例分泌性中耳炎按常规在治疗前、治疗后进行声导抗检查，测试项目包括鼓室导抗图、镫骨肌反射等。

Methods Tympanometries with 226, 678, 1000 Hz probe tones were obtained from 125 newborns (250 ears) by means of GSI Tympstar middle ear analyzer. The newborns with abnormal tympanograms were referred for temporale CT.

使用GSI Tympstar中耳分析仪，对125例（250耳）新生儿进行226、678、1000Hz探测音鼓室声导抗测试，结果异常或可疑者再行颞骨薄层CT检查明确有无中耳积液。

As for recurrence, the avoidance of a too-large postoperative tympanomastoid space, the establishment of a patent epi-mesotympanic route, and the preservation of adequate middle ear mucosa should be emphasized.

而避免术后中耳乳突腔过大，使上、中鼓室交通良好，以及尽量保持完整的中耳黏膜层，则是防止鼓膜再凹陷，再度形成胆脂瘤的良方。

Results: The angle that adjusting the reference line on the transverse plane is 32. 85°±6.76°, on the coronal plane is 14.15°±9.02°. The facial canal appears "ㄟ" on double oblique imaging geniculate ganglion, tympanic segment, post lap segment, mastoid segment were showed clearly. The achievement ratio is 100%. The segment displaying on double oblique imaging is more than transverse plane, coronal plane and sagittal plane.

结果：面神经管双斜位图像需要在横断位参考图像上旋转参考线的角度为32.85°±6.76°，在冠状位参考图像上旋转参考线的角度为14.15°±9.02°；在面神经管双斜位图像上，面神经管表现为&ㄟ&形，由前向后同时显示出膝状神经节、鼓室段、后膝部和乳突段；面神经管双斜位成像成功率为100%，面神经管行程的显示程度大于横断位、冠状位和矢状位。

The mean post- operative air conduction and bone conduction PTA were 36.59 dB and 24.23 dB, respectively.

对47例（47耳）胆脂瘤中耳炎病人，在清除病变的同时一期行鼓室成形术，用耳后带蒂肌筋膜骨瓣修复听骨链进行听力重建。

Methods60 sides of 30 dry temporal bone specimens had their mastoids outlined by an electric drill, and then the related structure of the posterior tympanum was exposed. Distances of the related anatomic structures were determined under surgical microscopy.

方法取成人30个干性颅骨的60侧颞骨，用耳科钻完成乳突腔气房&轮廓化&，充分暴露后鼓室的各相关结构，在手术显微镜下进行解剖学观察，并对有关结构之间的距离进行测量。

Discussion Application of HRCT in combination with MPR can acquire satisfying multi-view images of the details of the tympanums.

鼓室结构精细，应用高分辨CT扫描模式，辅以多平面重组技术可获得令临床满意的多角度图像，有利于制定治疗方案。

Results The high resolution of reconstructed images, which are comparable to the cross section images, directly displayed from different angles the appearance of pathological changes and the neighboring anatomic structures of the tympanums.

结果：重建图像清晰度良好，从不同角度显示了鼓室病变的形态及邻近解剖的关系，直观性强，可与横断面图像相媲美。

The major HRCT findings were presented with soft tissue mass in 89 middle ears(100%),the destruction of temporal bone including enlargment of the tympanic cavity 89 ears(100%),tympano scutum 55 ears(61.80%),ossicular chain 82 ears(92.13%),facial nerve cannal 54 ears(60.67%),semicircular canal 18 ears(20.22%),external auditory canal 10 ears(11.24%),tympanic tegmen 15 ears(16.85%),vestibular 1 ear(1.12%),cochlea 1 ear(1.12%) and sigmoid sinus plate 7 ears(7.86%).

HRCT表现为：中耳腔扩大伴软组织团块89耳(100%)，盾板破坏55耳(61.80%)，听小骨破坏82耳(92.13%)，面神经骨管破坏54耳(60.67%)，半规管破坏18耳(20.22%)，外耳道骨质破坏10耳(11.24%)，鼓室盖破坏15耳(16.85%)，前庭及耳蜗破坏各1耳(1.12%)，乙状窦周围骨质破坏7耳(7.86%)。

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）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
