Methods: Fifteen adults presenting indications of electro-acoustic stimulation (pure-tone audiometry (PTA) thresholds \u226470 dB below 750 Hz) were implanted with the EVO\u2122 electrode array. Hearing thresholds were collected at five time-points from CI activation to twelve months (12M) after activation. Hearing thresholds and hearing preservation profiles (HEARRING group classification) were assessed. Results: All subjects had measurable hearing thresholds at follow-up. No case of complete loss of hearing or minimal hearing preservation was reported at any time point. At activation (Nact = 15), five participants had complete hearing preservation, and ten participants had partial hearing preservation. At the 12M time point (N12m = 6), three participants had complete hearing preservation, and three participants had partial hearing preservation. Mean hearing loss at activation was 11 dB for full range PTA and 25 dB for PTAs low-frequency (125\u2013500 Hz). Conclusions: This study provides the first longitudinal follow-up on associated hearing profiles to the EVO\u2122 electrode array, which are comparable to the literature. However, other studies on larger populations should be performed.<\/jats:p>","DOI":"10.3390\/jcm10235604","type":"journal-article","created":{"date-parts":[[2021,12,1]],"date-time":"2021-12-01T01:43:22Z","timestamp":1638323002000},"page":"5604","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["One
