Objective: To explore the obliteration of the old mastoid cavity and reconstruction of the posterior canal wall after radical mastoidectomy. 目的:探讨陈旧性根治性乳突术腔填塞及外耳道后壁缺损的修复方法。
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
AN APPLIED ANATOMICAL STUDY OF THE ENDOLYMPHATIC SAC SURGERY VIA MASTOID APPROACH 2. Anatomical Observation of the External Aperture of the Vestibular Aqueduct and the Mastoid Cavity 经乳突入路行内淋巴囊手术的应用解剖研究&二、前庭小管外口及乳突腔解剖
Impacts of Mastoid Plombage and Cavity of Concha on the Efficacy of Formation of Radical Mastoidectomy 乳突腔充填术及耳甲腔成形术对乳突根治术效果的影响
Rebuild scute with auto-bone or infill the mastoid cavity with auto bone pieces; 自体骨片盾板修复,或碎骨填塞乳突腔;
Conclusion: Mastoid cavity plombage and cavity of concha formation can help to shrink the mastoid cavity and increase the effect of radical mastoidectomy through ventilation, conduction and epithelia keratinization. 结论:耳甲腔成形术及乳突腔充填术可以缩小乳突腔,促进乳突腔的通气引流及上皮化,提高乳突根治术的效果,同时有利于鼓室成形术。
Brain Herniation ( Temporal Lobe) into Mastoid Cavity 乳突中耳腔内大脑颞叶疝
The radiological features on the CT scan were: ① a tissue mass ( cholesteatoma) in the tympanic and mastoid cavity; CT显示胆脂瘤的病理改变为①鼓室乳突腔内胆脂瘤影;
We will make a long time observation for the self-clean capability of mastoid cavity. 对该方法术后乳突腔的自洁能力将作长期的随访。
Objective: The role mastoid cavity plombage played in restoring physiological function of external meatus in open method tympanoplasty was studied. 目的:探讨乳突腔充填术在开放式鼓室成形术中对恢复生理性外耳道功能的作用。
Enlargment of the tympanic and mastoid cavity; 鼓室乳突腔扩大;
Methods On 60 sides adult temporal bone specimens, the related anatomic structures were well exposed by opening the mastoid cavity and removing the lateral wall of external auditory canal and tympanic scutum. 方法利用成人60侧颞骨标本,用牙科钻磨开乳突腔,打开外耳道外侧壁和鼓室盾板,充分暴露后鼓室入路手术中有关的解剖结构。
Objective: To investigate the effect of mastoid plombage and cavity of concha formation on radical mastoidectomy. 目的:探讨耳甲腔成形术及乳突腔充填术在乳突根治术中的应用价值。
