Fully implantable Otologics MET Carina™ device for the treatment of sensorineural and mixed hearing loss: Audio-otological results

AbstractConclusion: Our results attest that the Otologics MET Carina™ is a viable treatment for moderate to severe sensorineural hearing loss (SNHL) and for cases of mixed hearing loss, and that in selected cases it could represent an alternative to conventional hearing aids. Objectives: To describe our experience with the fully implantable Carina™ in eight adult patients, seven with moderate to severe SNHL and one with mixed hearing loss. Methods: Eight implanted adult patients were submitted to a comprehensive audiological evaluation. Results: We did not record any surgical relevant complication in any of the patients, nor any significant postoperative variation in hearing thresholds, for air conduction or bone conduction, indicating the absence of surgical damage to the cochlea. All the patients demonstrated improvements in speech perception abilities with the device functioning and reported subjective benefits. With regard to the postoperative adverse effects, we had problems with feedback noise, whic...
