Title: Values of imaging evaluation in cochlear implantation
Abstract: Objective:To evaluate the values of imaging examination in pre-and postoperative cochlear implantation.Methods: Preoperative HRCT and MRI of temporal bone were routinely performed in all of 37 patients with sensorineural deafness,and an improved Stenver view radiography was made after surgery.Postoperative CT scanning was done in 5 of 37 cases. Results:Of 37 patients with congenital sensorineural deafness,Mondini malformation 2 cases(4 ears),dilated aqueduct of vestibule 2 cases(4 ears),labyrinthine ossification 1 case(1 ear) and stenotic internal auditory canal 1 case(2 ears) are well displayed on CT.Mondini malformation 3 cases(6 ears),dilated aqueduct of vestibule 2 cases(4 ears) and concomitant dilated endolymphatic sac one case(2 ears),and labyrinthine fibrosis 2 cases(2 ears) are demonstrated clearly on MRI.The shape and location of all of implanted electrodes were well revealed on improved Stenver view radiograph. The dislocative electrode one case was definitely showed on CT.Conclusion:CT and MRI play an important role in preoperatively evaluating cochlear implantation,and using combined improved Stenver view radiography and CT scanning was a more significantive evaluating method in postoperatively.
