“…Such ossification has been intraoperatively confirmed by several studies [Quaranta et al, 2005;Tamplen et al, 2016;Vashishth et al, 2017]. Vashishth et al [2017] found that although 60.5% (23/38 ears) of their cohort of CI users with otosclerosis had evidence of ossification, many nonetheless had good auditory outcomes.…”

Cochlear Implant Users with Otosclerosis: Are Hearing and Quality of Life Outcomes Worse than in Cochlear Implant Users without Otosclerosis?

Background: The otosclerotic process may influence the performance of the cochlear implant (CI). Difficulty in inserting the electrode array due to potential ossification of the cochlea, facial nerve stimulation, and instability of the results are potential challenges for the CI team. Objectives: To evaluate hearing results and subjective outcomes of CI users with otosclerosis and to compare them with those of CI users without otosclerosis. Method: Retrospective review of 239 adults with bilateral profound postlingual deafness who underwent unilateral cochlear implantation between 1992 and 2017. Hearing and speech understanding were assessed via pure-tone audiometry and speech perception tests. Subjective outcomes were assessed via the Nijmegen Cochlear Implant Questionnaire (NCIQ), the Glasgow Benefit Inventory (GBI), and the Hearing Implant Sound Quality Index (HISQUI₁₉) at 6 months, 12 months, and at the last follow-up. Results: Subjects were 22 CI users with otosclerosis and 217 without otosclerosis. Both groups had a similar duration of deafness and age at CI implantation. Results did not significantly differ according to group: no significant intergroup difference was found regarding the frequency of complete electrode insertion, facial stimulation, reimplantation, or PTA4 scores at the last follow-up. Regarding speech perception, no significant intergroup difference was found on any test or at any interval. Further, subjective outcomes, as measured by the GBI, NCIQ, and HISQUI₁₉, did not significantly differ between groups. Conclusions: Adults with otosclerosis and profound hearing loss derive significant benefit from CI use. Audiological and self-reported outcomes are not significantly different from that of other CI users with postlingual deafness.

“…The occurrence of facial nerve stimulation in CI recipients with otosclerosis is well known [Bigelow et al, 1998;Seyyedi et al, 2013;Tamplen et al, 2016]. It has been suggested that in cases of otosclerosis, the impedance of the otic capsule is reduced and this increases the potential diffusion of electrical current through the bone.…”

“…Lin et al reported that 40 % of children with severe to profound SNHL had abnormal MRI findings and 24 % had MRI findings that could explain their hearing loss [25]. The higher diagnostic yield of MRI relative to CT must be balanced with the increased cost associated with MRI and the need for sedation and additional time compared with CT. 2014 Medi-Cal reimbursement rates for a CT temporal bone were $212, $953 for an MRI of the IAC, and $250 for sedation during the exam [28]. …”

Opinion statement Hearing loss is the most common sensory disorder in the USA. The diagnosis of congenital hearing loss starts with newborn hearing screening, which is best performed with auditory brainstem evoked responses in order to avoid the risk of missing auditory neuropathy spectrum disorder. A careful history and physical exam can occasionally help reveal the etiology for congenital hearing loss. Imaging studies, either CT temporal bones or MRI of the internal auditory canals without gadolinium, and genetic testing, in particular for connexin 26, connexin 30, and Pendred syndrome, are the most useful diagnostic tests. Management of congenital hearing loss involves early fitting of amplification. Early cochlear implantation, preferably before 2 years of age, should be strongly considered for children with bilateral severe hearing loss.

“…Computed tomographies (CTs) and magnetic resonance imagings (MRIs) have been traditionally used to evaluate cochlear implant (CI) candidates. The utility of preoperative imaging in pediatric CI candidates is well documented because anatomic abnormalities can alter surgical planning in up to 20% of cases . However, the utility of preoperative imaging is yet to be determined in adult CI candidates with postlingual deafness.…”
