To assess the safety and efficacy of an intraoral bone conduction (IOBC) hearing prosthesis after 12 months of use.Study design
Prospective cohort study.Setting
Multisite study including private practice, hospital-based practice, tertiary care, and academic medical centers.Patients
Patients aged 18 years or older with single-sided deafness (SSD).Main outcome measure(s)
At the end of 6 months and 12 months, patients were asked to complete the Abbreviated Profile of Hearing Aid Benefit (APHAB) questionnaire and SSD questionnaire in addition to audiometric testing.Results
Eighty-one patients completed the study. Hearing thresholds remained the same throughout the study. APHAB results showed a significant benefit (p < 0.001) in categories of ease of communication, reverberation, background noise, and global score. The SSD questionnaire showed a high satisfaction among participants, with 93.8% of patients likely to recommend the IOBC. Dissatisfaction was highest with regard to patient’s ability to eat with device, with only 55.6% satisfied. No serious adverse events were reported during the study.Conclusion
The IOBC is a safe and effective alternative to percutaneous osseointegrated hearing implants for patients with SSD. Patient satisfaction and improved hearing benefit are observed after 1 year of using the device. The IOBC significantly benefitted patients in APHAB categories of ease of communication, reverberation, background noise, and the overall global hearing score. The in-the-mouth transducer is the least-liked feature for some patients, particularly with regard to eating; however, the majority of patients are willing to deal with the size of the device for the hearing benefit gained.
