This retrospective study aimed to evaluate the efficacy of the Esteem® middle ear implant in sensorineural hearing loss (SNHL) of different degree as well as to compare it with that obtained with conventional hearing aids. Fifteen out of 30 adults patients who received an Esteem® middle ear device for rehabilitation of sensorineural hearing loss met the primary eligibility criterion of prior, continuous use of conventional hearing aids. Study population included moderate-to-severe SNHL (8 patients) and severe-to-profound SNHL (7 patients). Audiometric measurements included free-field pure-tone and speech audiometry in Esteem®-aided, HA-aided, and baseline threshold. For speech audiometry, speech reception threshold (SRT) and word recognition score (WRS) were assessed. Subjective benefit was evaluated by Client Oriented Scale of Improvement (COSI) questionnaire. In all the subjects, SRT and WRS showed improvement both with conventional HA and Esteem® in respect to the unaided situation. Although not statistically significant, a slight prevalence of the Esteem® performances was recorded both audiometrically and as subjective satisfaction score. The Esteem® middle ear device demonstrated appreciable benefit for rehabilitation of SNHL of different degree, comparable to what can be achieved by conventional hearing aids. In addition, this rehabilitative process may enable also individuals presenting with severe-to-profound SNHL to achieve remarkable functional outcomes.
