Purpose To modify the management of open mastoid cavity and external acoustic meatus. To analysis the principle of improving the surgery quality and to employ in clinical practice more extensively. 目的对开放式乳突术腔与处耳道口的处理方法进行改良,并分析其在提高手术质量中的原理,在临床进一步推广应用。
Modificatory Method of Management for the Open Mastoid cavity and the Opening of External Acoustic Meatus 开放式乳突术腔与外耳道口处理的改良方法
There were 2-4 arteries around the cerebellopontine angle segment of the facial-acoustic nerve complex entering the inner acoustic meatus in each side. The arteries were connected with each other. 兔每侧面听神经复合体小脑脑桥角段周围有2~4支小动脉进入内听道,互相吻合。
Objective: To discuss the clinical value of treatment with ultraviolet ray and ultrashort wave on external acoustic meatus. 目的探讨紫外线并超短波治疗外耳道疾病的临床应用的治疗价值。
Results The facial nerve was divided into five segments, namely, cerebellopontine angle segment, internal acoustic meatus segment, labyrinthine segment, tympanum segment and mastoid segment. 结果面神经颅内段分为五段,即脑桥小脑角段、内耳道段、迷路段、鼓室段和乳突段。
The angle between the horizontal ICA and the line which connects the ICA genu to the medial lip of the internal acoustic meatus is 67.1 ± 4.3 °. ICA水平段与ICA膝部和内耳道内侧缘连线的夹角为67.1°±4.3°。

Conclusions The expression of c-fos and c-jun gene protein in cholesteatoma epithelium was far stronger than that in normal external acoustic meatus skin. The c-fos and c-jun genes induce and maintain hyperplasia of cholesteatoma epithelium through integrating into activator protein-1. 结论胆脂瘤组织中c-fos、c-jun蛋白产物较正常外耳道皮肤显著增高,c-fos、c-jun蛋白产物结合成AP-1,诱发并维持胆脂瘤上皮的高度增生。
The cerebellopontine angle segment and internal acoustic meatus segment paralleled the vestibulocochlear nerve. 脑桥小脑角段和内耳道段与位听神经伴行;
Results ( 1) CT thin tomographic scan can show relations between the posterior wall of the internal acoustic meatus and bone labyrinths; 结果(1)CT断层薄扫可较好地显示骨迷路与内耳道后壁的关系及岩锥气化程度,高颈静脉球现象;

Clinical Analysis of External Acoustic Meatus and Tympanic Cavity Plastics 先天性外耳道闭锁中耳畸形临床分析
Objective To study the line from infraorbital edge to external acoustic meatus as a scanning baseline in the location of AC-PC plane. 目的研究外耳门中点与眶下缘最低点的连线(简称眶听线)作为扫描基线对获得AC-PC平面的临床价值。
The membrana tympani is about6mm in diameter and forms the dorso-medial wall of the medial end of the external acoustic meatus. 鼓膜北京鸭的鼓膜直径约6毫米,构成外耳道内端的背侧壁。
[ Method] To examine or to make surgery estimates on external acoustic meatus, tympanic membrane, middle ear and so on with diameter of 2.7 mm, 4.0 mm, 30 ° 70 ° aural endoscope from different angles. 方法选用直径2.7mm、4.0mm的30°、70°不同角度的耳内镜对外耳道、鼓膜、中耳等在不同角度进行检查或手术评估。

16 cases have no response to audiological test, and MRI films indicate that configuration of inner acoustic meatus and cochlear nerve is normal in 14 cases. 上述听力学检查无反应的16例中的14例MRI检查提示内听道和听神经结构形态正常。
Identify The important structures of the petrosal bone including the groove for the greater superficial petrosal nerve, the facial hiatus, the arcuate eminence, the facial n., the petrous ridge, and the internal acoustic meatus. 在岩骨表面确认岩浅大神经沟、面神经裂孔、弓状隆起、内听道口、岩嵴等解剖标志。
Changed distinctly in 1 year. Conclusion: ( 1) The diagnostic criteria, 4mm, for bony external auditory canal stenosis could not be applied to children before 6 years. The study about bony external acoustic meatus might be performed from 2 months old children. 结论:(1)骨性外耳道的研究可从生后2月儿童开始;骨性外耳道狭窄的诊断标准4mm并不适用于6岁以下儿童。
