“…Near-complete HP is possible in a minority of patients when the full-length FLEXsoft electrode is inserted with minimal trauma, corroborating the results of Helbig et al (13) whose 21 patients, followed for a shorter period, achieved similar HP rates. Improved speech understanding was not seen in individuals with near-complete HP relative to others.…”

“…This suggests that most hearing loss happened at the time of surgery or shortly afterward, emphasizing the importance of meticulous surgical technique and atraumatic electrode design. In contrast, other studies have shown a measurable decrease in HP rates over time (3,13). Fibrosis, foreign body reaction and/or natural progression of disease may cause hearing loss that happens later.…”

“…HP is generally defined by an allowable change of HTL (preoperatively versus postoperatively) that may be 10 dB HL (7,13,15,17,18), 20 dB (5,7), 30 dB (3,13), or 40 dB (18). Some have defined HP as the preservation of any measurable hearing (2,5,8,9,12,13,15,17).…”

“…The electrode is not yet available in the United States pending Food and Drug Administration approval. Reports have suggested that HP is possible with the FlexSoft (12,13). Our goal was to determine the degree of HP seen after a full insertion with the FlexSoft device.…”

“…There is now converging data and an increasing number of reports on the possibility of deep electrode insertion and hearing preservation [Punte et al, 2010;Helbig et al, 2011;Usami et al, 2011]. This advantage may be used by the patient for better frequency resolution.…”

Hearing Preservation after Cochlear Implantation Using Deeply Inserted Flex Atraumatic Electrode Arrays

et al. 2012

The aim of this study was to investigate hearing preservation in adults receiving cochlear implants with Flex arrays. Fifteen adults (19 ears) implanted with Flex EAS® (n = 4) or Flex Soft® (n = 15; MedEL, Innsbruck, Austria) were included in this retrospective study. The mean array insertion length was 25 ± 0.9 mm (n = 19), and the mean cochlear coverage was 435 ± 14.5° (n = 19), with no difference between EAS and Soft arrays. Residual low-frequency hearing was preserved in all implanted ears but deteriorated [pure-tone average (125–1000 Hz) 55.1 ± 2.90 dB before vs. 81.0 ± 3.02 dB after surgery (n = 19, p < 0.01)]. Both Flex arrays allow deep insertion with reproducible hearing preservation.

IMPORTANCECochlear implants are a treatment option for individuals with severe, profound, or moderate sloping to profound bilateral sensorineural hearing loss (SNHL) who receive little or no benefit from hearing aids; however, cochlear implantation in adults is still not routine.OBJECTIVE To develop consensus statements regarding the use of unilateral cochlear implants in adults with severe, profound, or moderate sloping to profound bilateral SNHL. DESIGN, SETTING, AND PARTICIPANTSThis study was a modified Delphi consensus process that was informed by a systematic review of the literature and clinical expertise. Searches were conducted in the following databases: (1) MEDLINE In-Process & Other Non-Indexed Citations and Ovid MEDLINE, (2) Embase, and (3) the Cochrane Library. Consensus statements on cochlear implantation were developed using the evidence identified. This consensus process was relevant for the use of unilateral cochlear implantation in adults with severe, profound, or moderate sloping to profound bilateral SNHL. The literature searches were conducted on July 18, 2018, and the 3-step Delphi consensus method took place over the subsequent 9-month period up to March 30, 2019. MAIN OUTCOMES AND MEASURESA Delphi consensus panel of 30 international specialists voted on consensus statements about cochlear implantation, informed by an SR of the literature and clinical expertise. This vote resulted in 20 evidence-based consensus statements that are in line with clinical experience. A modified 3-step Delphi consensus method was used to vote on and refine the consensus statements. This method consisted of 2 rounds of email questionnaires and a face-to-face meeting of panel members at the final round. All consensus statements were reviewed, discussed, and finalized at the face-to-face meeting. RESULTSIn total, 6492 articles were identified in the searches of the electronic databases. After removal of duplicate articles, 74 articles fulfilled all of the inclusion criteria and were used to create the 20 evidence-based consensus statements. These 20 consensus statements on the use of unilateral cochlear implantation in adults with SNHL were relevant to the following 7 key areas of interest: level of awareness of cochlear implantation (1 consensus statement); best practice clinical pathway from diagnosis to surgery (3 consensus statements); best practice guidelines for surgery (2 consensus statements); clinical effectiveness of cochlear implantation (4 consensus statements); factors associated with postimplantation outcomes (4 consensus statements); association between hearing loss and depression, cognition, and dementia (5 consensus statements); and cost implications of cochlear implantation (1 consensus statement).CONCLUSIONS AND RELEVANCE These consensus statements represent the first step toward the development of international guidelines on best practices for cochlear implantation in adults with SNHL. Further research to develop consensus statements for unilateral cochlear implantation in children, bilateral c...
