Introduction: The electrode length is one of the many factors impacted on results of cochlear implantation. Among lateral wall flexible electrode arrays the latest one is FLEX26 (MED-EL GmbH, Innsbruck, Austria). The main aim of the study was to evaluate the preservation of residual hearing, the level of speech understanding, and quality of life after cochlear implantation with FLEX26 electrode array. Methods: The study was conducted in a tertiary referral centre. Fifty-two patients implanted unilaterally with FLEX26, including 10 EAS patients (electric acoustic stimulation) and 42 ES patients (electric stimulation). The intervention was minimally invasive cochlear implantation via the round window. Pure-tone audiometry (0.125–8 kHz) was performed preoperatively and at 1, 6, and 12 months postoperatively. Twelve-month hearing preservation was established using HEARRING group formula. Quality of life was measured with AQoL-8D (Assessment of Quality of Life–8 Dimensions) pre- and postoperatively. Results: Residual hearing was preserved in 88.8% EAS patients. Quality of life was significantly better postoperatively in comparison to preoperative period (the effect size for overall quality of life was 0.49). Especially, it increased in relationships and senses dimensions (the effect sizes 0.47 and 0.44, respectively). Conclusion: Preservation of residual hearing can be achieved in the majority of patients implanted with FLEX26. Improvement of quality of life was also documented. FLEX26 seems to be an option for surgeons who seek an electrode providing sufficient cochlear coverage. [ABSTRACT FROM AUTHOR]

The aim of this study was to evaluate the psychometric properties of patient-reported visual analogue scale (VAS) ratings. All of the participants (100 Polish-speaking adults) completed a Tinnitus Functional Index (TFI) once and a 4-component VAS twice over a period of 3 days. Spearman's correlation coefficients between the VAS score and global TFI ranged from ρ = 0.52 for VAS-coping (VAS-C) to ρ = 0.81 for VAS-annoyance (VAS-A). Using the Bland-Altman method, the agreement ranged from 93% for VAS-A to 96% for VAS-distress (VAS-D). Interclass correlation coefficients ranged from 0.67 for VAS-C to 0.90 for VAS-A. The VAS cutoff points representing significant tinnitus severity ranged from 45 points for VAS-C to 66 points for VAS-D. VAS scales are a valid and reliable brief screening tool for obtaining quick information about tinnitus. [ABSTRACT FROM AUTHOR]

This study investigates the psychometric properties of the Polish version of the Tinnitus and Hearing Survey (THS-POL), which is a tool for evaluating what proportion of patients' tinnitus is due to hearing problems and what proportion is specifically due to the tinnitus. The THS-POL was created using the translation-backtranslation method. Study participants completed the THS-POL twice over a period of 3 days. The test-retest analysis shows excellent strength of correlations (THS-POL subscale A r = 0.89, subscale B r = 0.9). For subscales A and B, reliability measured using Cronbach's alpha was α = 0.86 and 0.95, respectively, in the first administration and α = 0.91 and 0.94 in the second administration. Confirmatory factor analysis confirmed a good 2-factor structure of the THS. Convergent validity evaluated using the Pearson product-moment correlation between subscale A (tinnitus) and the Tinnitus Handicap Inventory shows good correlations. In conclusion, the THS-POL is a valid and reliable screening tool to assist in deciding about the optimal management approach. [ABSTRACT FROM AUTHOR]

Hearing disorders become an increasingly important issue that influences quality of life and many other economic factors. Due to the prolongation of human life and the more active lifestyles of people in retirement age, there is an increasing requirement for the available treatment options of hearing loss in the aging population. The aim of this study was to compare the hearing preservation outcomes of adult patients implanted with the Cochlear™ Nucleus® CI422 when divided into two groups by age, younger and older than 65 years of age. The study cohort consisted of 62 patients implanted from January 2011 through December 2013 at our clinic. All patients were assessed and classified according to the hearing preservation classification. Comparing the results between subgroups, we observed that the degree of hearing preservation was greater in younger adults than in older adults. Results of this review may suggest that deeper insertion is to be recommended for an older population of cochlear implant recipients. © 2015 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]
