作者对贝耳氏面瘫进行减压术治疗,为减少出血,多采用Xylocain局麻。采用耳后切口,凿开乳突,从后向前开放上鼓室,暴露砧骨短突和槌骨头。开放下鼓室,并扩大通道,向前看到锥隆起、圆窗,向上看到砧镫关节。在16倍以上显微镜下断离砧镫关节,勿损伤关节面,然后从乳突侧断寓砧槌关节,由鼓窦口向后摘出砧骨。看清面神经管水平段后,削去在通道后方形成的桥,扩大鼓窦。从水平段向下磨薄骨管壁一直到与二腹肌嵴相交之处。再从水平段向上暴露骨管达膝状神经节。从膝状神经节到茎乳孔的骨管壁均窘薄后,除去骨壁。从锥段向下方切开神经鞘,然后再向上方切开,切开要充分,但勿伤及神经,并充分止血。然后将砧骨复位,只要关节面没有损伤,恢复原位无困难。乳突腔内放硅胶管引流,缝合骨膜和皮肤。至于减压范围,如无
The author of Behs facial paralysis decompression treatment, to reduce bleeding, more use of Xylocain local anesthetic. After the incision with the ear, hewn open the mastoid, open the upper tympanic cavity from the back to expose the incus incision and mallet head. Open the lower tympanum and expand the corridor to see the conical bulge forward, round the window and see the anvils upwards. In 16 times more under the microscope off the anvil joint, do not damage the articular surface, and then cut off from the side of the anastomosis mastoid ankle joints, removed from the drum by the incus incus incus. After seeing the level of the neural tube horizontal section, cut the bridge formed in the rear of the channel to expand the drum sinus. From the horizontal section of the thin bone wall down to the quadrigeminal abscess intersection. Then from the horizontal section up to the geniculate knee ganglion. From the geniculate ganglion to the stem canal, the osseous wall of the mammary fossa is embarrassed and the bone wall is removed. Cut the nerve sheath from the conical section downwards, and then incision to the top, incision should be sufficient, but do not hurt the nerve, and fully stop the bleeding. Then resection of the incus, as long as no damage to the articular surface, restore the original position without difficulty. Put masticular silicone tube drainage, suture periosteum and skin. As for the decompression range, if not
