Abstract:
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 imagiological 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 which 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.
