Abstract

Objective: To report the proportion of subjects successfully fit with combined electroacoustic stimulation (EAS) compared with those with preserved hearing (HP) after cochlear implantation (CI). In addition, to 1) report the trends in HP and EAS fit rates over time and 2) identify and characterize those patients who preferred the electric only condition. Study Design: Retrospective chart review. Setting: Tertiary referral center. Patients: Two hundred five postlingually deafened adults with bilateral SNHL and a preoperative low-frequency pure-tone average 80 dB HL or better in the ear to be implanted. Interventions: Subjects underwent CI from 2013 to 2018 with routine pre- and postoperative audiometric testing performed at 6- and 12-months. Main Outcome Measures: Percentage of patients fit with EAS, low-frequency pure-tone average, and threshold shift. Results: Overall, 141 patients (78.6%) had HP at activation and 42.6% were fit with EAS. Rates of EAS fitting improved from 36.4% in 2013 to 69.0% in 2018. 93.5% of patients had hearing preserved in 2018 compared with 57.9% in 2013. Six patients rejected EAS after a trial period either because of discomfort or poor sound quality. Eight patients had EAS removed because of loss of aidable hearing over time (between activation to 12 mo). Conclusions: Despite the high percentages of HP in the literature, EAS may be under-utilized in the adult CI population. Moving toward a universal definition of HP across institutions may better represent the potential for EAS fitting and a clinical measure capable of identifying patients best suited to benefit from EAS.

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal OTOLOGY & NEUROTOLOGY due to its progression and the good impact it has achieved in recent years, according to the agency Scopus (SJR), it has become a reference in its field. In the year of publication of the work, 2021, it was in position , thus managing to position itself as a Q1 (Primer Cuartil), in the category Otorhinolaryngology.

From a relative perspective, and based on the normalized impact indicator calculated from World Citations provided by WoS (ESI, Clarivate), it yields a value for the citation normalization relative to the expected citation rate of: 3.1. This indicates that, compared to works in the same discipline and in the same year of publication, it ranks as a work cited above average. (source consulted: ESI Nov 13, 2025)

Specifically, and according to different indexing agencies, this work has accumulated citations as of 2026-04-02, the following number of citations:

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2026-04-02:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 29.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 30 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 3.
  • The number of mentions on the social network X (formerly Twitter): 5 (Altmetric).
