Abstract:
Objective To investigate the value of CT as preoperative and postoperative imaging technique for cochlear implant candidates.Methods Axial high-resolution temporal bone CT and three-dimensional reconstruction of inner ear were performed in 44 patients with sensorineural hearing loss. Cochlear view radiography was performed routinely in postoperation cases. CT scanning was performed in 3 postoperation cases.Results There were 1 case (2 ears) with Mondini malformation type Ⅰ, 2 case (4 ears)with Mondini malformation type Ⅱ in 32 patients with prespeech deafness. There were 2 case (4 ears) with chronic suppurative otitis meadia, 1 case (2 ears) with inner ear ossification,3 cases (6 ears)with large vestibular aqueduct syndrome,1 case (2 ear)with cochlear sclerosis in 12 patients with postspeech deafness. 1 case with intracochlear electrode knot and otitis meadia was found by CT.Conclusion CT plays an important role in selecting patients, observing implanted electrode and finding postoperative complication.
