To explore the correlation between the width of the bony cochlear nerve canal (CNC) and long-term auditory rehabilitation after unilateral cochlear implantation (CI) in pediatric patients with congenital deafness and bilateral cochlear nerve canal stenosis (CNCS). A retrospective review was performed on 10 patients with bilateral CNCS and bilateral congenital profound hearing loss who each underwent unilateral cochlear implantation. The width of the CNC was determined on computed tomography (CT) imaging and following CI, auditory and speech performance following CI were graded using categories of auditory performance (CAP), speech intelligibility rating (SIR), and the meaningful auditory integration scale (MAIS) at 24 months following implantation. No correlation was noted between CAP score and CNCS at 24 months post CI ( P > .05). A positive correlation was noted between SIR score and CNC width (ρ = .81, P < .05). Similarly, a positive correlation was noted between MAIS and CNC width (ρ = .71, P < .05). The width of the CNC in patients with CNCS is positively correlated with some long-term auditory and speech outcomes after CI.

<b><i>Introduction:</i></b> Audiovestibular symptoms are rare in sarcoidosis, but they may also be the first manifestation of the disease. Sudden or progressive bilateral hearing loss is usually associated with vestibular impairment. The mechanism of hearing loss remains unclear, but clinical presentation and magnetic resonance imaging suggest a retrocochlear site for the lesion in most patients. Several cases of hearing recovery after corticosteroid treatment have been reported. In patients with severe or profound hearing loss, the benefit of cochlear implantation is challenging to predict in the case of auditory neuropathy and is rarely described. We present a case series of cochlear implantation in patients with documented neurosarcoidosis. <b><i>Results:</i></b> Seven cases of cochlear implantation in 4 patients with neurosarcoidosis are reported. All of the patients showed a great improvement very quickly in both quiet and noise. Speech performance remained stable over time with a follow-up ranging from 4 to 11 years, even in patients who had disease exacerbation. <b><i>Conclusion:</i></b> Cochlear implantation is possible in deaf patients with neurosarcoidosis. The excellent benefit obtained in our patients suggests a particular type of neuropathy, but endocochlear involvement cannot be entirely ruled out.

Cochlear implantation is an expensive but effective lifelong intervention for individuals with a severe-to-profound hearing loss. The primary aim of this study was to survey the short- and long-term costs of cochlear implantation. Individuals (N=154) using cochlear implants obtained from the University of Stellenbosch-Tygerberg Hospital Cochlear Implant Unit in Cape Town, South Africa were surveyed using a questionnaire and patient record review. The questionnaire used a combination of closed and open-ended questions to gather both quantitative and qualitative information. Costs were categorised as short- and long-term costs. All costs were converted to constant rands (June 2010) using the Consumer Price Index to allow for comparison in real terms over time. In the first 10 years of implantation the average estimated costs incurred by adults totalled R379 626, and by children R455 225. The initial purchase of the implant system was the most substantial cost, followed by upgrading of the processor. Travel and accommodation costs peaked in the first 2 years. On average the participants spent R2 550 per year on batteries and spares. Rehabilitation for children cost an average of R7 200. Insurance costs averaged R4 040 per year, and processor repairs R3 000 each. In addition to the upfront expense of obtaining the cochlear implant system, individuals using a cochlear implant in South Africa should be prepared for the long-term costs of maintenance, accessing the unit, support services and additional costs associated with use. Knowledge of these costs is important to ensure that individuals are successful users of their cochlear implants in the long term.

Objective. To describe the audiological, anesthesiological, and surgical key points of cochlear implantation after bacterial meningitis in very young infants.Material and Methods. Between 2005 and 2010, 4 patients received 7 cochlear implants before the age of 9 months (range 4–8 months) because of profound hearing loss after pneumococcal meningitis.Results. Full electrode insertions were achieved in all operated ears. The audiological and linguistic outcome varied considerably, with categories of auditory performance (CAP) scores between 3 and 6, and speech intelligibility rating (SIR) scores between 0 and 5. The audiological, anesthesiological, and surgical issues that apply in this patient group are discussed.Conclusion. Cochlear implantation in very young postmeningitic infants is challenging due to their young age, sequelae of meningitis, and the risk of cochlear obliteration. A swift diagnostic workup is essential, specific audiological, anesthesiological, and surgical considerations apply, and the outcome is variable even in successful implantations.

AbstractOur study compares the intelligibility of French-speaking children with a cochlear implant (N = 13) and age-matched children with typical hearing (N = 13) in a narrative task. This contrasts with previous studies in which speech intelligibility of children with cochlear implants is most often tested using repetition or reading tasks. Languages other than English are seldom considered. Their productions were graded by naive and expert listeners. The results show that (1) children with CIs have lower intelligibility, (2) early implantation is a predictor of good intelligibility, and (3) late implantation after two years of age does not prevent the children from eventually reaching good intelligibility.

Profound hearing loss makes it difficult for a person to fully integrate into society. Cochlear implantation is rightfully considered a universal and an effective method of rehabilitation of patients with severe and profound hearing loss. The advantages of binaural hearing are well known; the advantages of bilateral cochlear implantation over monolateral implantation are undeniable, due to the restoration of all binaural hearing effects. At the moment, the relevance of simultaneous cochlear implantation, especially among children, and its benefits compared with sequential implantation are being discussed. It is known that there are special groups of patients among patients with hearing loss; they are either unrehabilitated at all or rehabilitation measures for which are ineffective. Special patient groups include patients with unilateral acquired or congenital deafness, asymmetric and residual hearing loss. Patients in these groups often complain of poor speech intelligibility, especially against a background of noise, inability to localize the source of sound, one-sided or two-sided tinnitus, and, as a result, a deterioration in the quality of life. All abovementioned makes us think about the need to revise the indications for cochlear implantation and study this issue in detail.

AbstractJervell, Lange-Nielsen syndrome is a condition that causes profound hearing loss and disruption of the normal cardiac rhythm. This disorder is a form of long QT syndrome, a cardiac disorder that causes the cardiac muscle to take longer than usual to recharge between beats. A retrospective case study was performed to document cochlear implantation in three profoundly deaf children (two of them siblings) with Jervell, Lange-Nielsen syndrome. We discuss diagnosis and management of this syndrome and also the long-term performance of cochlear implantation in these Iranian patients, referring especially to the role of the ENT specialist in diagnosis and treatment. The collected data show that cochlear implantation can be relatively safely performed in patients with Jervell, Lange-Nielsen syndrome and that these children received significant benefit from cochlear implantation.
