【摘要】：通過探討正常成人顱腦橋小腦區(qū)解剖結構的特點和內窺鏡下識別方法及參考標志,及對病理條件下神經內窺鏡下橋小腦區(qū)解剖結構的特點和識別方法進行比較。為該區(qū)的顯微手術提供解剖學依據(jù)。 具體研究方法為:在8具16側福爾馬林固定的成人尸頭標本和4具8側新鮮成人尸頭標本上進行各角度內鏡與顯微鏡對比觀察,模擬手術的內鏡下血管神經關系的解剖學研究。對15例聽神經瘤、1例膽脂瘤,2例三叉神經痛患者顯微手術中應用內鏡進行該區(qū)病理解剖觀察。 研究結論為不同角度的內鏡在不同層面的觀察有獨特的作用,30°的內鏡既有直視角又有側視角,尤其適用于觀察隱蔽區(qū)域,70°的內鏡特別適用于聽面束行程及內耳道底的觀察,并能明確內耳道內容物的關系�？蔀闃蛐∧X角區(qū)解剖提供更多信息。內鏡具有側視角,能越過淺層的阻擋結構,進入橋小腦角深部,觀察到手術顯微鏡下的死角或隱蔽結構,尤其重要的是,無需干擾任何結構,即可明確神經血管之間的關系。應用神經內鏡觀察橋小腦區(qū)病理條件下解剖結構的特點和識別方法,為該區(qū)的病變的顯微外科治療提供了解剖學基礎,可指導臨床操作。
[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.
