Objective: (1) Compare the non-device-related costs of bilateral simultaneous cochlear implantation (BSiCI) vs. unilateral, and (2) establish a dollar amount for potential cost savings in direct costs for BSiCI vs. sequential cochlear implantation (CI).
Methods: Data from all CI cases performed during the fiscal year 2010-2011 were retrospectively reviewed without exception. Fifty-four patients received unilateral CI and 36 received BSiCI. Demographics and data regarding direct costs associated with the operation and immediate in hospital post-operative period were collected.
Results: The total operating room (OR) time for unilateral and BSiCI was 3 hours 00 minutes and 4 hours 37 minutes, respectively, with a mean difference of 1 hour and 36 minutes (SD = 0 hours:06 minutes). The cost of OR and post-anesthetic care unit supporting staff was $3102 and $4240 for unilateral and BSiCI, respectively, with a mean difference of $1138 (SD = 216). Unilateral CI supplies totaled $1348 compared to $1822 for BSiCI supplies with an average difference of $438 (SD = 123).
Conclusion: The total direct costs for a unilateral CI (excluding implantable device and surgeon fees) were $4362 compared to $5823 dollars for BSiCI. Simultaneous implantation can lead to a potential saving of $2901 compared to sequential implantation.

Objective: To assess the impact of cochlear implantation (CI) and speech perception outcomes on the quality of life (QoL) of adult CI users and their communication partners (CP) one-year post-implantation.
Design: This research is part of a prospective multicenter study in The Netherlands, called SMILE (Societal Merit of Intervention for hearing Loss Evaluation).
Study Sample: Eighty adult CI users completed speech perception testing and the Nijmegen Cochear Implant Questionnaire (NCIQ).
Ultra-high-resolution CT of the temporal bone before cochlear implantation for pre-operative prediction of chorda tympani nerve management and round window access.
Eur Arch Otorhinolaryngol

Guilloz Imaging Department, Central Hospital, University Hospital Center of Nancy, Nancy, 54000, France.
Background And Purpose: To evaluate various anatomical parameters and their relationship to chorda tympani nerve (CTN) injury and round window (RW) access during cochlear implantation.
Materials And Methods: Ultra-high-resolution CT images of 66 patients were retrospectively reviewed and compared with operative reports. The facial recess and the round window were analyzed, mainly using the chorda-facial angle (CFA), the width of the facial recess, the CTN-tympanic annulus distance, the RW-mastoid portion of the facial nerve angle, and the type of RW.
The Heterozygous p.A684V Variant in the Gene Is a Mutational Hotspot Causing a Severe Hearing Loss Phenotype.
Genes (Basel)

Department of Hearing Implant Sciences, Shinshu University School of Medicine, Matsumoto 390-8621, Japan.
Background/objectives: A heterozygous mutation in the gene is responsible for autosomal dominant non-syndromic hearing loss (DFNA6/14/38) and Wolfram-like syndrome, which is characterized by bilateral sensorineural hearing loss with optic atrophy and/or diabetes mellitus. However, detailed clinical features for the patients with the heterozygous p.A684V variant remain unknown.

Cochlear implantation (CI) is a highly effective treatment for profound hearing loss in elderly individuals, including those with ARHL. However, factors influencing the success of CI in the elderly population are not fully understood. Hence, we sought to investigate the association of regional cerebellar gray matter volume with effectiveness of CI in the elderly.

Cochlear implants are well established devices for treating severe hearing loss. However, due to the trauma caused by the insertion of the electrode and the subsequent formation of connective tissue, their clinical effectiveness varies. The aim of the current study was to achieve a long-term reduction in connective tissue growth and impedance by combining surface patterns on the electrode array with a poly-L-lactide coating containing 20% diclofenac.
