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 Twenty-two pieces of temporal bone were taken for this study. The mastoid cavity was opened, scutum removed,"bridge" broken down, posterior wall of external auditory canal abraded and the related anatomic structures were fully exposed. The distance between the origin of facial nerve canal and the anterior border of round window （ OOFNC-ABORW ）, between the highest point of the facial nerve canal and the bottom of posterior mastoid sinus,and between the stapes head and round window niche was measured under operating microscope.

方法取成人颞骨22侧（左右各11侧），用耳科钻磨开乳突腔，去上鼓室盾板、断"桥"，磨低骨性外耳道后壁，充分暴露相关结构，在手术显微镜下测量面神经管垂直段起始部前缘至圆窗龛前缘的距离、面神经管最高点与后鼓室底壁之间的距离、锥隆起的高度（即锥隆起基底到锥隆起顶端的距离）、镫骨头至圆窗龛前缘的距离。

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。

MethodsTwenty volunteers with normal hearing level and tympanic pressure were enrolled and kept at airtight container. The inner pressure was changed to 2 kPa and 4 kPa below normal atmospheric pressure in 50 s and recovered to the normal pressure, the pure tune hearing threshold of 500, 1 000 and 2 000 Hz and tympanic pressure were measured, and acoustic impedance curve characteristic and tympanic membrane appearance were recorded at each time points.

方法选取听力和鼓室压力正常的受试者20例，即单耳40耳，评估其于50s改变密闭模拟电梯容器压力低于正常大气压2kPa、50s改变密闭容器压力低于正常大气压4kPa、以及压力恢复至正常水平时，言语频率500、1000、2000Hz的纯音听阈，鼓室压值和声阻抗曲线图形形态，以及鼓膜形态。

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。

Abstract］ Objective To evaluate the effect of salpingocatheterism through pharyngeal opening of auditory tube under nasal endoscope and Ⅱ tympanoplasty.

摘要］ 目的探讨鼻内镜在视频系统下行咽鼓管咽口置管及鼓室成形Ⅱ型手术的效果。

Salpingocatheterism under nasal endoscope provides enlarged operation field and operation angle,flexible operation,accurate location.

鼻内镜在视频系统下咽鼓管置管具有独特的优势，视野阔、视角大、操作灵活、部位准确，扩大了鼓室成形术的适应证。
