摘要
目的:探讨乙状窦前移小儿人工耳蜗植入术式的选择和术中处理的方法,为特殊情况下的人工耳蜗植入手术的顺利完成提供经验。方法:538例行人工耳蜗植入手术的听力障碍患儿,术前进行的常规听力学与影像学检查,术前通过高分辨率CT判断乙状窦是否前移,行人工耳蜗植入手术中证实分为显著前移和轻度前移。结果:538例通过常规术式进行人工耳蜗植入患儿中,乙状窦轻度前移64例,占11.9%,对常规人工耳蜗植入手术无影响。4例患儿乙状窦显著前移,对常规人工耳蜗植入手术带来困难,占0.74%,通过处理骨性外耳道后壁和切除砧骨顺利完成手术。结论:小儿人工耳蜗植入手术患儿中,乙状窦轻度前移者对手术无影响,显著前移者经过适当手术处理,亦能成功进行手术。
Objective：To summarize the operation approach and management during cochlear implant operation in children with sigmoid sinus antedisplacement.Method：Five hundred and thirty-eight profound hearing loss children were performed auditory and imageological examinations before cochlear implant.We analyzed the location of the sigmoid sinus from the high resolution CT scan and then performed cochlear implant to all these patients.Result：In all these 538 cochlear implant children,4 cases（0.74%）had significant sigmoid sinus antedisplacement which cause the operation more difficult,64 cases（11.9%） had slight sigmoid sinus antedisplacement witch did not impact the ordinary cochlear implant procedures.Conclusion：Significant sigmoid sinus antedisplacement that impact cochlear implant operative procedures were seldom happen in children.In 538 cochlear implant children of our center,4 cases had significant sigmoid sinus antedisplacement that impact cochlear implant operative procedures,we successfully complete these 4 operation through removal of the incus and abrasive reduction the posterior wall of bony external acoustic meatus.
