【摘要】：通過(guò)探討正常成人顱腦橋小腦區(qū)解剖結(jié)構(gòu)的特點(diǎn)和內(nèi)窺鏡下識(shí)別方法及參考標(biāo)志,及對(duì)病理?xiàng)l件下神經(jīng)內(nèi)窺鏡下橋小腦區(qū)解剖結(jié)構(gòu)的特點(diǎn)和識(shí)別方法進(jìn)行比較。為該區(qū)的顯微手術(shù)提供解剖學(xué)依據(jù)。 具體研究方法為:在8具16側(cè)福爾馬林固定的成人尸頭標(biāo)本和4具8側(cè)新鮮成人尸頭標(biāo)本上進(jìn)行各角度內(nèi)鏡與顯微鏡對(duì)比觀察,模擬手術(shù)的內(nèi)鏡下血管神經(jīng)關(guān)系的解剖學(xué)研究。對(duì)15例聽(tīng)神經(jīng)瘤、1例膽脂瘤,2例三叉神經(jīng)痛患者顯微手術(shù)中應(yīng)用內(nèi)鏡進(jìn)行該區(qū)病理解剖觀察。 研究結(jié)論為不同角度的內(nèi)鏡在不同層面的觀察有獨(dú)特的作用,30°的內(nèi)鏡既有直視角又有側(cè)視角,尤其適用于觀察隱蔽區(qū)域,70°的內(nèi)鏡特別適用于聽(tīng)面束行程及內(nèi)耳道底的觀察,并能明確內(nèi)耳道內(nèi)容物的關(guān)系。可為橋小腦角區(qū)解剖提供更多信息。內(nèi)鏡具有側(cè)視角,能越過(guò)淺層的阻擋結(jié)構(gòu),進(jìn)入橋小腦角深部,觀察到手術(shù)顯微鏡下的死角或隱蔽結(jié)構(gòu),尤其重要的是,無(wú)需干擾任何結(jié)構(gòu),即可明確神經(jīng)血管之間的關(guān)系。應(yīng)用神經(jīng)內(nèi)鏡觀察橋小腦區(qū)病理?xiàng)l件下解剖結(jié)構(gòu)的特點(diǎn)和識(shí)別方法,為該區(qū)的病變的顯微外科治療提供了解剖學(xué)基礎(chǔ),可指導(dǎo)臨床操作。
[Abstract]:The characteristics of anatomical structure of cerebellopontine area in normal adults and the identification methods and reference markers under endoscope were discussed. The characteristics and recognition methods of anatomical structure of cerebellopontine area under neuroendoscopy were compared. To provide anatomical basis for microsurgery in this area. The specific methods were as follows: 8 adult cadaveric head specimens fixed with formalin and 4 fresh adult cadaveric head specimens were examined with different angles of endoscopy and microscope. The anatomic study of vascular and nerve relationship under endoscope was carried out on the simulated operation of 8 adult cadaveric heads and 4 fresh adult cadaveric heads. 15 cases of acoustic neuroma, 1 case of cholesteatoma and 2 cases of trigeminal neuralgia were studied by endoscopy. The conclusion is that endoscopy at different angles has a unique effect on different levels of observation. A 30 擄endoscope has both a straight and a lateral angle of view, which is especially suitable for observing the concealed area, and a 70 擄endoscope is especially suitable for observing the distance of the auditory surface bundle and the bottom of the inner auditory canal. The relationship between the contents of the inner ear canal and the contents of the inner ear canal can be clarified. It can provide more information for the anatomy of cerebellopontine angle area. The endoscope has a lateral angle of view and can cross the shallow barrier structure into the deep part of the cerebellopontine angle and observe the dead angle or concealed structure under the surgical microscope. It is especially important that the relationship between the nerve and blood vessels can be clarified without interfering with any structure. The anatomical structure of cerebellopontine area under pathological conditions was observed by neuroendoscopy, which provided anatomical basis for microsurgical treatment of the lesions, and could be used to guide clinical operation.
