Abstract:
Objective To study the auditory perception and speech ability outcomes after cochlear implantation in prelingually deaf children with extremely severe neurosensory hearing loss and comorbid leukoencephalopathy.Methods Our study included 14 prelingually deaf children with leukoencephalopathy (confirmed by preoperative MRI scanning) who were treated with cochlear implantation in the Department of Otorhinolaryngology Head and Neck Surgery of Hainan Provincial People''s Hospital, including 8 males and 6 females of 1~6 yr with a mean age of 3.8 yr.Sixteen synchronous prelingually deaf children without central nervous system (CNS) diseases were also included as the control group, including 11 males and 5 females of 1~6 yr with a mean age of 4.4 yr.All the patients underwent pre-surgical assessments of audiology, radiology, speech ability and intelligence before cochlear implantation via transmastoid facial nerve recess approach was done, after which rehabilitation was provided at the Hainan Rehabilitation Center for Deaf Children.Categories of auditory performance (CAP) and speech intelligibility rate (SIR) were employed as the assessment criteria for the outcome of surgery, the scores of which at different timepoints after surgery were statistically compared through paired t-test between the two groups.Results All the patients gained post-surgical hearing and speech abilities to different degrees, whereas CAP and SIR scores both chronologically improved in the both groups.No statistical difference was revealed either in CAP or in SIR scores between the two groups at 6, 12 and 24 months after surgery (P>0.05).Conclusion Children with extremely severe neurosensory hearing loss can be reated with cochlear implantation even if they have comorbid leukoencephalopathy.The effects of auditory and speech rehabilitation for the same age patients with leukoencephalopathy are similar to those without leukoencephalopathy in 2 years after surgery.
