鼓室

Eustachian tube function, tympanogram and air hearing threshold were measured with an acoustic immitance audiometer and pure tone audiometer in 56 patients (112 ears).

利用纯音测听及声阻抗检测56例慢性鼻窦炎患者的纯音听力、鼓室导抗图和咽鼓管功能。

The crus breve incudis is an important marker for operation. The anatomical position of PE is constant. The depth of PTC affects the procedure for cochlear implant surgery via mastoid process-facial recess approach. The location of vestibular window and the round window is relatively stable, so the stapes head can be used as a reference for drilling scala tympani.

结论砧骨短脚是手术的重要标志；锥隆起解剖位置恒定；后鼓室的深浅对该进路的人工耳蜗植入手术的难易程度有重要影响；前庭窗与圆窗的位置关系相对稳定，因此镫骨头可作为参照标志来确定鼓阶钻孔的位置。

ConclusionWhen the facial recess is opened, distance from the chordal eminence to the pyramid segment and the pyramidal eminence can be regarded as the width of the facial recess. The pyramidal eminence and the facial canal are regarded as the basis for searching for each other.

结论经后鼓室进路手术开放面神经隐窝时，鼓索隆起至面神经管锥曲和至锥隆起的距离可作为开放面神经隐窝的宽度，面神经管与锥隆起可作为手术中互为寻找的依据。

Results:① The distance between handle of malleus and stapes head was(2.38±0.19)cm(2.00～2.70cm), the point selecting for measuring was outer margin of handle of malleus and stpes head.②The cross section form of one_third of the handle of malleus at the end, was triangle, the anteroposterior diameter of handle of malleus was(0.79±0.12)mm, the exterior and interior diameter was(0.58±0.10)mm at the crook point,the angle of line of manubrium mallei laid(83.24±8.33)°(66～98°)posteroinferior to arch of zygoma.③The long axis of prosthesis formed(27.60±1.75)°(24.6～30.2°)angle with the perpendicular of stapes.④The dependablity between the malleus_stapes distance and transverse diameter of tympanum, the location of umbo in tympanic membrane, the diameter of manubrium mallei, angle of line of manubrium mallei and arch of zygoma were not statistically significant.

结果：①锤_镫距离最短为(2.38±0.19)cm(2.00～2.70cm)，测量点为锤骨柄末端1/3处外缘和镫骨头；②锤骨柄末段1/3横断面形状接近三角形，弯曲处前、后方向直径为(0.79±0.12)mm，内、外方向直径为(0.58±0.10)mm；锤骨柄与颞线的成角为(83.24±8.33)°(66～98°)；③赝复物长轴与镫骨垂直方向成角平均为(27.60±1.75)°(24.6～30.2°)；④锤_镫距离与鼓室横径、鼓脐在鼓膜上的位置、锤骨柄直径、锤骨柄的方位的可能相关因素之间相关性检验无统计学意义。

Results: HRCT findings of choleastoma of the middle ear were abnormal soft-tissue shadows in tympanic cavity and antrum and accompany with bony destruction, including dislocation and distruction of the ossicular chain, the erosion of scutum and...

结果 ：66例中耳胆脂瘤HRCT表现为鼓室/鼓窦内团块状软组织影和骨质改变，包括听骨硬化、移位、破坏，盾板破坏及中耳腔扩大，有的还伴有乙状窦、天盖、面神经管及水平半规管的破坏。

Methods: Micranatomical study was carried out on 30 sides of human temporal bones to measure the location of umbo in tympanic membrane, the distance between handle of malleus and stapes head, the diameter of handle of malleus.

取成人完整鼓室标本15例(30侧)凿除乳突和外耳道前、后、下壁，保留上壁，在手术放大镜下测量鼓脐在鼓膜上的位置、锤骨柄至镫骨头距离、锤骨柄直径等。

Methods 300 cases (560 ears)of temporal CT axial images which were divided into two groups were retrospectively analyzed by statistics methods. There were 158 cases(316 ears)in normal group and 142 cases(244 ears)in abnormal group .The incidence of high jugular bulb , dehiscent jugular bulb, anterior location of sigmoid sinus, large sinus tympani, aberrant internal carotid artery, dehiscent of the facial nerve canal, excess of Korner's septum and mastoid antrum dysplasia were recorded.

回顾性分析300例(560耳)颞骨的HRCT轴位像，根据诊断结果将其分为正常组与疾病组，正常组158例(316耳)，疾病组142例(244耳)，统计以下变异的发生率：①颈静脉球高位②颈静脉球裸露③乙状窦前置④鼓室窦深位⑤迷走颈内动脉⑥面神经管水平段裸露⑦岩鳞隔过长⑧鼓窦缺如，并对结果进行统计学分析。

For seeking a better tympanic implant so as to improve the curative effect of AOM, the effect of the silatic film was compared with that of the nickel-titanium scaffold implanted in the tympanum after the operations of experimental AOM in cats.

为了寻求更好的鼓室植入物以改善粘连性中耳炎的治疗效果，用猫进行实验比较了硅片和镍钛支架在实验性粘连性中耳炎术后鼓室内植入的效果。

Results:①The center of the homogeneous density soft tissue masses (mean CT value was 50HU) were located in the middle and lower tympanum,and the external auditory canal or the pharyngotympanic tube was involved in the earlier period;②the destructed b...

结果：中耳癌的CT特征：①表现为以中、下鼓室为中心的软组织密度灶，密度均匀，CT值50HU左右，外耳道及咽鼓管早期受累；②呈溶骨性骨质破坏，形态不规则，边缘无骨硬化表现，外耳道后壁破坏较前壁严重；③病灶侵入颞叶，形成肿块，灶周脑水肿不明显；④增强扫描见病灶有中度强化。结论：CT能确定中耳癌的存在及精确显示肿瘤累及范围。

Results The eustachian tube extend anteriorly and medially from middle ear cavity to the pharynx nasalis, about 1.53±0.08 mm long, 0.22±0.03 mm wide, 1.14±0.08 mm high.
