“…Mean FHG values were satisfactory in patients with types of hearing loss. The mean FHG for sensorineural hearing loss is in accordance with the literature ranging from 13.9 to 28.1 dB on average . Two studies reported higher mean hearing gains in patients with conductive and mixed hearing loss (32 dB and 36.1 dB).…”

“…The mean FHG for sensorineural hearing loss is in accordance with the literature ranging from 13.9 to 28.1 dB on average. [15][16][17][18] Two studies reported higher mean hearing gains in patients with conductive and mixed hearing loss (32 dB 19 and 36.1 dB 20 ). When analyzed by each frequency, significant hearing gains were reached at each frequency from 500 to 4,000 Hz.…”

Objective To assess the audiological and long‐term medical and technical follow‐up outcomes of an active middle ear implant. Methods This was a retrospective medical chart analysis of all patients provided with an active middle ear implant in a tertiary academic medical referral center between September 1, 1998, and July 31, 2015. Main outcome measures were medical and technical complications, revisions, reimplantations, explantations, coupling approaches, mean time of use, pre‐ and postoperative hearing thresholds, functional hearing gain across frequencies (250–4,000 Hz), and Freiburg monosyllablic word test at 65 dB. Results One hundred and three patients were identified. Fifteen were implanted bilaterally (n = 118 Vibrant Soundbridge devices [MED‐EL, Innsbruck, Austria]). Seventy‐seven devices were implanted for sensorineural and 41 for mixed and conductive hearing loss. Patients used the implant for 6.7 years (range 0.7 months–17.9 years) on average. Ninety‐one patients (77.12%) were using the device at the end of the observation period. An overall complication rate of 16.1% was observed. The revision and explantation rates were higher for devices implanted between 2004 and 2006. The device failure rate was 3.4%. Audiological evaluation showed significant hearing gains for both hearing loss patient groups. Conclusion This long‐term follow‐up reveals the reliability of the active middle ear implant in a single center. Overall complication rate and device failure rate are acceptable. The complication rate was higher during implementation of alternative coupling approaches. The audiological benefit was satisfactory in patients with all hearing loss types. The majority of implanted patients used the implant at the end of the observation period. Level of Evidence 4 Laryngoscope , 129:477–481, 2019

“…The AC threshold of 1-8 kHz reached the normal hearing threshold level (<25 dB). In summary, a high frequency achieved a better effect than a lower frequency, which was consistent with a previous report [14]. The effect of hearing improvement in the high-frequency region (1-8 kHz) was better than the effect of our previously reported stapes implantation and round window implantation.…”

The surgery was successful. Pure-tone air conduction thresholds across the frequencies of 0.25-8 Hz were improved by 35 dB (preoperation, 69.2 dB; postactivation, 34 dB) in patient 1 and 46.6 dB (preoperation, 75.8 dB; postactivation, 24.2 dB) in patient 2. Normal hearing thresholds were achieved in the range of 1-8 kHz in both patients. A sentence recognition rate of up to 100% (65 dB SPL in a quiet room) was attained by both patients after surgery and VSB activation at 3 months postoperatively.

“…VSB-aided speech audiometry in quiet (Freiburger monosyllables speech test at 65 dB SPL) showed with 85% (Patient 1) and 80% (Patient 2) higher speech discrimination scores with the SP2 coupler than that in previous studies with application of the FMT to the long incus process, where speech discrimination was variously reported to be 57% to 61% (20,30) or 73% to 75% (31). Clearly, long-term results and a larger number of patients using this technique are required.…”
