“…The study group was divided between patients with favourable prognosis and patients with unfavourable prognosis for the outcome, on the basis of the existing literature [11,41]. Patients 4, 7, 8, 11, 12 and 13 were considered patients with unfavourable prognosis because their aetiology was, respectively, chronic otitis media, otosclerosis, infantile meningitis and otosclerosis for the last three patients.…”

“…Aetiology of hearing impairment, duration of deafness, gender and presence or absence of a Binaural Hearing Rehabilitation did not seem to affect audiological outcomes, even in case of unfavourable aetiology, such as meningitis and otosclerosis. It is reported that aetiology could affect audiological outcomes [11,14,[41][42][43][44]. Meningitis, otosclerosis and chronic otitis media present a risk of partial cochlear ossification that does not contraindicate the insertion of electrodes but could reduce the hearing outcome.…”

To date, no clear specific cognitive predictors of speech perception outcome in older adult cochlear implant (CI) users have yet emerged. The aim of this prospective study was to increase knowledge on cognitive and clinical predictors of the audiological outcome in adult cochlear implant users. A total of 21 patients with post-lingual deafness, who were candidates for cochlear implantation, were recruited at the Department of Ear, Nose and Throat, University of Torino (Italy) and subjected to a pre-operatory neuropsychological assessment (T0) and an audiological examination after 12 months of implantation (T12). Patients who, at T12, had a 60 dB verbal recognition above 80%, were younger (z = −2.131, p = 0.033) and performed better in the Verbal Semantic Fluency Test at T0 (z = −1.941, p = 0.052) than subjects who had a 60 dB verbal recognition at T12 below 80%. The most significant predictors of the CI audiological outcome at T12 were age (β = −0.492, p = 0.024) and patients’ TMT-A performance at baseline (β = −0.486, p = 0.035). We conclude that cognitive processing speed might be a good predictor of the level of speech understanding in older adult patients with CI after one year of implantation.

“…There are a heterogeneous group of studies that have reported reasonable outcomes for cochlear implantation in patients with advanced otosclerosis. 4 Advanced otosclerosis poses surgical challenges with regards to cochlear implantation in the presence of round window or cochlear ossification. Abnormal bone formation may necessitate surgical drilling in the vicinity of the round window for access or the use of an alternative approach, such as subtotal petrosectomy.…”

Cochlear implantation in advanced otosclerosis: utility of pre-operative radiological assessment in predicting intra-operative difficulty and final electrode position

Objective. This study aimed to determine if pre-operative radiological scoring can reliably predict intra-operative difficulty and final cochlear electrode position in patients with advanced otosclerosis. Method. A retrospective cohort study of advanced otosclerosis patients who underwent cochlear implantation (n = 48, 52 ears) was compared with a larger cohort of post-lingually deaf adult patients (n = 1414) with bilateral hearing loss and normal cochlear anatomy. Pre-operative imaging for advanced otosclerosis patients and final electrode position were scored and correlated with intra-operative difficulty and speech outcomes. Results. Advanced otosclerosis patients benefit significantly from cochlear implantation. Mean duration of deafness was longer in the advanced otosclerosis group (19.5 vs 14.3 years; p < 0.05). Conclusion. Anatomical changes in advanced otosclerosis can result in increased difficulty of surgery. Evidence of pre-operative cochlear luminal changes was associated with intra-operative difficult insertion and final non-scala tympani position. Nearly all electrodes implanted in the advanced otosclerosis cohort were peri-modiolar. No reports of facial nerve stimulation were observed.
