“…Thus, seven patients were implanted on the right side, two on the left side and one binaural IC patient (Table 2), in accordance with the literature so far [11] [12]. During the revisional surgery there was no indication to implant the contralateral side, unlike what is reported in the literature, which shows a reimplantation rate of 85% on the same side of the original implant and 15% on the contralateral side, which can be explained by several factors such as evaluation period, experience of the implantation center and the surgeon, socio-cultural characteristics of the implanted population, and technological advances of the implanted internal units [7].…”

Introduction: Cochlear implant (CI) surgery allows hearing reestablishment among individuals with severe to profound hearing loss. However, only few patients will need a surgical reassessment. Objectives: To verify the incidence of surgical reassessment among adult patients; to verify the reasons that led the second surgery to be performed; to verify the efficacy-and audiological outcomes-of revisional surgery. Method: A longitudinal retrospective cohort study was carried out with the review of medical records, of adult patients, with bilateral severe to profound sensorineural hearing loss who underwent to revisional surgery, from 2004 to 2016 at a CI Center, in Brazil. Results: One hundred fifty-eight CI surgeries were performed among 137 adult patients. Fourteen revisional surgeries were performed among 10 patients: five surgeries were due by displacement of the internal unit; one because of having excessive subcutaneous tissue; one due to non-progression of the electrodes during the initial surgery, one late tympanic membrane perforation, one late facial palsy and, one due to a suture dehiscence in the surgical incision with exposure of the internal unit. Conclusions: The incidence of surgical reassessment among adult CI patients was 8.9%. All implanted patients that underwent a new surgical approach maintained an improved auditory threshold after revisional CI surgery.

“…The presence of residual hearing is essential for the use of bimodal stimulation. Bimodal stimulation is a non-invasive way of providing binaural hearing, and has been suggested for patients who use unilateral CI and who have residual hearing in the contralateral ear 28 . One study 29 found that approximately 60% of adult CI candidates have residual hearing, mainly in low frequencies in at least one ear.…”

Objective: to analyze temporal ordering auditory ability in unilateral cochlear implant users with bimodal stimulation. Methods: the study included 15 unilateral cochlear implant users, six with bimodal stimulation and nine with exclusive cochlear implant and a control group consisting of 15 hearing individuals. Both groups underwent the standard duration and the standard frequency tests for temporal ordering auditory ability analysis. In the inferential analysis of the data, the nonparametric statistical tests Mann-Whitney and Kruskal-Wallis were used (p<0,05). Results: there was a significant difference in the performance of the standard frequency test, and subjects with bimodal stimulation presented a better performance than those with exclusive cochlear implants. The standard frequency test was associated with education and speech therapy. On the other hand, in the standard duration test, there was a relation with the implanted ear. The most frequent errors were discrimination for both temporal tests. Conclusion: bimodal stimulation, education and speech therapy influenced the performance of the frequency pattern test, while the implanted side influenced the performance of the duration pattern test.

“…It is known that binaural hearing reduces the shadow effect of the head and provides the squelch effect, leading to binaural summation leading to central auditory processing and integration when auditory stimulus arrives from both ears [8]. This present study assessed the effect of choosing the side of cochlear implant surgery, whether the right or the left side, on speech perception and listening skills in a pediatric group of patients.…”

Introduction: Cochlear implants are the main option for rehabilitation of severe to profound hearing loss patients. Binaural stimulation is the most adequate modality, but the side of choice of cochlear implant surgery on young deafened children has not been completely clarified.Objective: To investigate the influence of choice of side on cochlear implant surgery, whether the right or the left side, on speech perception and listening skills in a pediatric group Materials and Methods: A retrospective study was conducted to analyze listening skills performance of children submitted to cochlear implantation between 2003 and 2010. Fifty-three patients were submitted to cochlear implant surgery (28 in the right ear and 25 in the left ear), by the same surgical team. Oral communication was classified as insufficient, satisfactory, and excellent, according to a subjective evaluation. The MacArthur-Bates Communicative Development Inventory was used for all patients to evaluate the development of listening skills. Results:The mean age at the time of the activation was 38.35 months (range, 14 to 69.53). The mean age in the right ear implanted group was 37.42 months (range, 15 to 60.42), and in the left ear implanted group 39.72 months (range, 14 to 69.53; P = 0.59). The median time of use was 73.63 months in the right ear group, and 55.03 months in the left ear group (P = 0.051). Regarding oral communication skills, no statistical differences were found. Average score for the MacArthur-Bates Inventory was 476 in the right ear and 576.5 in the left ear (P = 0.659). Conclusion:We found no differences regarding listening skills after cochlear implantation in the right or the left side, which may imply that the side of choice in cochlear implantation is not crucial for listening skills development.

Is there a best side for cochlear implants in post-lingual patients?

Abstract: The cochlear implant in the ear with the worst auditory residue favors a bimodal hearing, which would allow the binaural summation, without compromising the improvement of the audiometric threshold and the speech perception.
