Osseointegrated hearing devices Power and SuperPower present indications for bone thresholds of 55 and 65 dB respectively. We conducted a prospective observational study of a series of six cases with mixed hearing loss for whom implantation of the DAO Ponto™ Super-Power was performed. Tonal and verbal evaluations without and with background noise (HINTS) were performed prior to implantation and six months after adaptation. All the participants showed improvement in tonal and verbal results, varying according to the degree of contralateral hearing loss. The verbal results with background noise were noteworthy, where most of the patients obtained a signal-to-noise ratio between 2 and 4 dB. The results in the APHAB and GBI questionnaires showed a reduction in the perception of the problem and an improvement in quality of life respectively. The results presented reflect the possibility of treatment of mixed hearing loss with the Ponto™ SuperPower device.
