OBJECTIVE: The objective of this prospective, single-subject, repeated measures study was to evaluate the audiological benefit and patient satisfaction with an adhesive, pressure-free bone conduction hearing system (ADHEAR; MED-EL, Innsbruck, Austria) in patients who underwent middle ear surgery with transient hearing loss due to auditory canal tamponade.
METHODS: Eleven adult subjects suffering from transient conductive hearing loss were enrolled in the study and followed up to 3 weeks after middle ear surgery. Bone and air conduction thresholds were measured pre and postoperatively to evaluate eligibility for enrollment. Postoperative unaided and aided sound-field thresholds, as well as speech tests in quiet and noise were compared to confirm hearing improvement with the hearing system. To determine patient satisfaction, the SSQ12 and a system-specific quality of life questionnaire was administered to all subjects.
RESULTS: Speech perception for monosyllables in quiet improved by 46%, with statistical significance for the ADHEAR system compared to the unaided condition after one week. The functional hearing gain improved by 19 dB. Speech perception in noise with the device was - 6.7 dB SNR on average, with a statistically significant improvement of 2.7 dB SNR. The results of the questionnaire showed a high level of patient satisfaction and subjective hearing improvement. No serious skin reactions or other severe complications occurred.
CONCLUSION: As long as the auditory canal is blocked due to tamponade, patients benefit from hearing rehabilitation. This adhesive hearing system is a safe and effective device to treat transient conductive hearing loss and may considerably improve treatment for patients even with short-term hearing loss.
