Authors' objectives: A systematic review of literature was performed to assess the safety and effectiveness of the Esteem® system in terms of hearing gain, speech recognition and improvement in the quality of life of patients with moderate to severe sensorineural hearing loss.
Authors' recommendations: Two studies reported an improvement in hearing loss from moderate to mild. An improvement in speech recognition was also observed, with an average 29.5 dB decrease in speech reception threshold without hearing aid, as compared with the 11.8 dB decrease achieved through the use of the Esteem® system. The percentage of words that were correctly recognized with the Esteem® system ranged from 69 % and 80 % in all studies. Over 80 % of patients stated that the effectiveness of the Esteem® system was similar, better or much better than other hearing aids. Adverse events were generally mild. Explantations were mostly related to insufficient hearing gain or appearance of background noise. However, these results should be interpreted with caution due to the significant methodological limitations of the before-after studies (level of evidence 3). These studies were insufficient for the assessment of the effectiveness of the Esteem® system, since sudden changes occurred between measurements might alter the outcomes and cannot be undoubtedly attributed to the intervention. In addition, the sample size in most studies was small. However, the risk of bias in most studies was low in terms of losses and outcome evaluation.
