“…In this study, participants who had improvements in perceived duration of tinnitus or tinnitus loudness matches two weeks after LLLT, had significantly worse pure-tone thresholds compared to participants who showed no improvement (Table 4). Previously, Dejakum et al 20 applied medium-level (450 mW) laser therapy with the same wavelength (830 nm) to our study for chronic tinnitus 20 , but there was no therapeutic effect Treatment outcomes of tinnitus were compared between baseline and two weeks after 10-interventions. Respondents were defined as participants who improved the duration of tinnitus by at least one point or improved the tinnitus loudness matches by more than 5 dB SL.…”

Objectives: To evaluate the efficacy and safety of low-level light therapy (LLLT) using new irradiation parameters for chronic unilateral tinnitus with cochlear dysfunction. Design: A single-blind, randomized clinical trial Setting: Tertiary-care hospital center Participants: Participants who had a history of chronic unilateral tinnitus (≥ 3 months) and pure-tone thresholds greater than 15dB (averaged for 3k, 4k, and 6k Hz). Main outcome measures: Numerical rating scales (NRS) measuring loudness, duration, and annoyance, the tinnitus handicap inventory (THI), and psychoacoustical matches of tinnitus loudness and minimum masking levels (MML). Results: Thirty-eight participants were received either a 100-mW diode laser at 830-nm (TINI group; n=19) or placebo (sham group; n=19) irradiation through the tympanic membrane. No adverse events were reported during 2 weeks of 10-interventions (20 minutes/day, five days/week). The NRS measuring duration of tinnitus and psychoacoustical matches of tinnitus loudness significantly decreased over times in the TINI group (p<0.05). However, post-hoc analysis revealed that there was no significant decrease of tinnitus among different time points (baseline, during LLLT, immediately after LLLT, and two weeks after LLLT). There was no placebo effect in the Sham group. Participants who improved the duration by at least one point or improved the loudness matches by more than 5 dB SL two weeks after LLLT tended to have worse pure-tone thresholds. It may suggest that further study is needed in patients with worse pure-tone thresholds to evaluate the therapeutic efficacy of LLLT. Conclusion: Although this preliminary result is insufficient to support the therapeutic efficacy of new laser device for chronic tinnitus, further study is needed in a large number of selected patients.

“…A 450 mW infrared laser, which is more than 10 times stronger than our setup, has been used as a therapeutic alternative in chronic tinnitus with no patient discomfort. 31 Furthermore, in the hidden cochlear implant concept, the implanted unit would be able to communicate with the hidden external unit through the Bluetooth low energy module and give feedback about the signal strength and any possible misalignments during initial calibration. This could decrease energy consumption by reducing any unnecessary light intensity and minimising tissue heating.…”

Objective The hidden cochlear implant concept has two data transmission methods: Bluetooth low energy and transtympanic optical data transfer systems. This study aimed to present the hidden cochlear implant and compare the test results with the existing fully implanted cochlear implant. Method The Bluetooth low energy module was implanted into the implant bed. For the transtympanic optical data transfer tests, a receiver was passed through the posterior tympanotomy, and the transmitter was placed in the ear canal. Results The Bluetooth low energy module range was 5.2–17.5 m. Transtympanic optical data transfer reached a rate of 1 Mbit/s and had 99.22 per cent accuracy. Despite various obstacles, the accuracy of the transtympanic optical data transfer was more than 99 per cent with a 250 Kbit/s rate. The average power consumption was 310 mW for the implanted Bluetooth low energy module and 41 mW for the transtympanic optical data transfer receiver. Conclusion Bluetooth low energy is suitable to be used transcutaneously. Transtympanic optical data transfer is an effective and promising technology. Hidden use cochlear implants aim to have the aesthetics of a fully implantable cochlear implant with higher reliability and a magnet-free design with smart device integration.
