窥腔镜

（1） In common cavity malformation, in addition to the abnormal bony labyrinth such as the cochlea, vestibule and lateral semicircular canal, the inner ear perceptive organ such as the saccule, utricle and scala media were also abnormal.（2） Though we could not identify the basal membrane and sensory epithelia under micro-endoscopy, the utricle and saccule could be clearly identified.（3） During cochlear implantation in common cavity malformation, electrode insertion should be monitored under micro-endoscopy, the electrodes should be put close to the anterior wall of the cavity, otherwise the vestibular organ may be damaged.

（1）共同腔畸形极重度聋患者不仅前庭、外半规管和耳蜗的骨性结构形态发生了变化，而且腔内耳蜗中阶与前庭的球囊、椭圆囊的膜迷路结构形态也发生了变化；（2）微窥镜下分辨不出基底膜或听神经细胞的形态结构，可见畸形前庭的球囊、椭圆囊的囊性结构；（3）进行共同腔畸形人工耳蜗植入手术时，应在耳蜗内镜的监视下，将电极摆放到准确位置，尽可能贴近共同腔的前壁，不应损伤前庭器官。
