Middle Ear Implant for Sensorineural and Conductive Hearing Loss: Indications and Audiological Results

Background and Objectives Middle ear implants (MEI) have been reported to be an effective safe alternative for the treatment of sensorineural hearing loss (SNHL) conductive (CHL). This study aimed compare functional outcomes between SNHL CHL in terms audiological gains.Subjects Method The medical records 14 consecutive patients who underwent MEI surgeries from 2015 2019 by a single surgeon were retrospectively reviewed. Audiological changes using aids (HA) compared.Results In SNHL, mean unaided air-conduction pure tone audiometry (PTA), (57.7 dB HL) decreased significantly HA (44.7 41.4 HL), but with no significant difference each other. Unaided word recognition score (WRS) at 65 HL (45.1%) was improved (72.6% 76.6%), difference. CHL, bone-conduction PTA 77.1 (57.5-93.8) 44.1 (26.3-57.5) HL. Three could not use conventional HAs due otorrhea deformity external auditory canal previous 4 had used before MEI. Though both vibrant soundbridge (VSB) showed improvement thresholds (32.0 48.8 WRS (80.0% 94.9%), it only when VSB. There VSB.Conclusion can option patients, especially those suffered problems HA.
