QoL, CIs, QALYs, and Individualized Rehabilitation: The Clinical and Practical Benefits of Regularly Assessing the Quality of Life of Adult Cochlear Implant Recipients.

This study aimed to report quality of life (QoL) scores in unilateral cochlear implant (CI) users and to generate guidance for clinicians on using QoL measures to individualize CI counselling and rehabilitation and to increase access to CIs as a mode of rehabilitation. Participants (n = 101) were unilateral CI users with single-sided deafness (SSD; n = 17), asymmetrical hearing loss (AHL; n = 26), or bilateral hearing loss (Uni; n = 58). Generic QoL was assessed via the Health Utilities Index (HUI-3), and disease-specific QoL was assessed via the Speech, Spatial, and Qualities of Hearing scale (SSQ12) and Nijmegen CI Questionnaire (NCIQ) at preimplantation and at 6 and 12 months of CI use. All groups had significantly increased HUI-3 scores at both intervals. The SSD group showed significant benefit on the SSQ12 at visit 3, the AHL group showed significant benefit on the SSQ12 and most NCIQ subdomains at both intervals, and the Uni group showed significant benefit with both tests at both intervals. Unilateral CI recipients demonstrate improved QoL within the first 12 months of device use. Regular assessment with generic and disease-specific questionnaires has the potential to play an important role in personalizing treatment and possibly in increasing access to CI provision.

Using Generic and Disease-Specific Measures to Assess Quality of Life before and after 12 Months of Hearing Implant Use: A Prospective, Longitudinal, Multicenter, Observational Clinical Study.

The primary objectives of this study were to evaluate the effect of hearing implant (HI) use on quality of life (QoL) and to determine which QoL measure(s) quantify QoL with greater sensitivity in users of different types of HIs. Participants were adult cochlear implant (CI), active middle ear implant (VIBRANT SOUNDBRIDGE (VSB)), or active transcutaneous bone conduction implant (the BONEBRIDGE (BB)) recipients. Generic QoL and disease-specific QoL were assessed at three intervals: pre-activation, 6 months of device use, and 12 months of device use. 169 participants completed the study (110 CI, 18VSB, and 41BB). CI users' QoL significantly increased from 0-6 m device use on both the generic- and the disease-specific measures. On some device-specific measures, their QoL also significantly increased between 6 and 12 m device use. VSB users' QoL significantly increased between all tested intervals with the disease-specific measure but not the generic measure. BB users' QoL significantly increased from 0-6 m device use on both the generic- and the disease-specific measures. In sum, HI users experienced significant postoperative increases in QoL within their first 12 m of device use, especially when disease-specific measures were used. Disease-specific QoL measures appeared to be more sensitive than their generic counterparts.

Alternative Inverted Middle Fossa Approach in Bonebridge Surgery. Technique, Results and Complications

Abstract Introduction The transmastoid approach is the most recommended technique to Bonebridge surgery, while in patients with bad anatomy or in the canal wall down technique, retrosigmoid or Middle Fossa Approaches are the alternative surgical options. Objective To describe a novel alternative approach called inverted middle fossa approach (IMFA) and its technique and audiological outcomes. Methods Seven patients submitted to the IMFA were included. All patients presented conductive and mixed hearing loss with bone thresholds of the audiogram > 40 dB. The audiological test was conducted pre- and postoperatively. Results A total of 5 males and 2 females, aged 13,8 years old (range 6-25 years old) were studied. The average follow-up was of 20 months (12 to 32 months). All patients presented aural atresia, except one with severe osseous-fibrous dysplasia of the temporal bone. Two patients showed bilateral compromise, three patients had associated Goldenhar and Treacher Collins syndrome. On the preoperative audiograms, air conduction (AC) thresholds showed a PTA4 (0.5, 1, 2 and 4 kHz) of 66.7 dB (standard deviation [SD] = ± 7.8), while the bone conduction thresholds reached an average of 11.2 dB (SD = ± 6.9). The postoperative thresholds did not change, and additional sensorineural damage was not observed before activation. Four weeks after surgery, all the patients were fitted with the external processor. The postoperative audiological aided exam showed AC PTA 4 thresholds of 18.9 dB (SD = ± 5.9). Conclusion The IMFA allows the nearest position of the microphone to the external auditory canal. The technique is a suitable option to the 3 classical approaches with similar rate of audiological results. More investigation is needed to determine the benefit of the novel approach compared with the others.

One-Year Follow-Up in Children with Conductive Hearing Loss Using ADHEAR.

BACKGROUND: The ADHEAR™ system (MED-EL, Innsbruck, Austria) is a nonsurgical bone conduction device (BCD) to treat conductive hearing loss (CHL) and single-sided deafness. In contrast to the nonsurgical alternatives on headbands or spectacle frames, the audio processor of ADHEAR is placed retroauricularly on an adhesive adapter. The published evidence on the performance of this system is limited to studies with a trial period of 2-8 weeks. OBJECTIVE: This study assesses audiological and subjective outcomes over a period of 12 months, on patients with congenital aural atresia (CAA) using the ADHEAR hearing system. METHOD: Fifteen children (mean age: 9.4 ± 4 years; range: 5-16 years) diagnosed with CAA (7 uni/8 bilateral) were included in this prospective, observational, repeated-measures study. Each subject used ADHEAR for 1 year, and the performance was evaluated after 1, 6, and 12 months. Free-field audiometry and speech discrimination tests were performed, and hearing-, general health- and device-specific questionnaires were used. RESULTS: The unaided sound field threshold improved from an average PTA4 of 63.6 ± 3.4 dB HL to an aided average PTA4 of 29.3 ± 3.0 dB HL after 1 month of device use. The word recognition score (WRS) improved from an average of 27.9 ± 15.9% unaided to an aided average WRS of 91.3 ± 4.4% (p = 0.0003) after 1 month, 92.0 ± 4.1% (p = 0.0002) after 6 months, and 92.7 ± 5.3% (p < 0.0001) after 12 months using the ADHEAR system compared to the unaided condition for all 3 time points. The improvements in the speech in noise at 1, 6, and 12 months were as well consistent over time. The average improvement at the signal to noise ratio (SNR) of +5 dB was 58% and 53% at the SNR of +0 dB. No complications were reported, and all patients continued to use the ADHEAR after the study end. The questionnaire results revealed high user satisfaction and an average wearing time of 12 h per day. CONCLUSION: This 12-month trial of the nonsurgical adhesive BCD in CAA patients showed sufficient and reliable audiological and subjective outcomes, long wearing time, and high acceptance. The ADHEAR can be considered a suitable option to treat children with CAA for the given indication, without the drawbacks of nonsurgical devices that use pressure for retention of the audio processor or the costs and possible complications involved with a surgical alternative.
