Objective(s): To investigate the differences in percutaneous versus passive transcutaneous bone-conduction stimulation in individuals with single-sided deafness. Study Design: Prospective, single-subject. Setting: Tertiary academic referral center. Patients: Adult bone-anchored implant listeners with single-sided deafness using a percutaneous implant system. Interventions: Experienced percutaneous bone anchored implant recipients were tested in the percutaneous and transcutaneous conditions using a BAHA 5 (Cochlear Corp., Cochlear Bone-Anchored Solutions, Mölnlycke, Sweden) sound processor on the patient's own abutment and on a softband. Main Outcome Measures: Phoneme recognition was assessed using Consonant-Nucleus-Consonant (CNC) words for soft (47 dB SPL) and average (62 dB SPL) speech inputs. Speech perception in noise performance was also assessed for soft (47 dB SPL) and average (62 dB SPL) speech inputs using sentences presented in multi-talker babble. Aided free-field thresholds were obtained in both conditions using warble tone stimuli. Results: Compared with percutaneous bone-conduction stimulation, transcutaneous stimulation demonstrated reduced effective gain for high frequency stimulation. Transcutaneous stimulation required higher signal to noise ratios to achieve comparable performance to the percutaneous condition. Phoneme recognition was poorer in transcutaneous versus percutaneous stimulation with the most significant impact observed for soft speech inputs. Conclusion: A significant performance gap in speech recognition is observed between percutaneous and transcutaneous bone-conduction stimulation in individuals with single-sided deafness at the same signal to noise ratios. Compared with percutaneous bone-conduction stimulation, transcutaneous stimulation demonstrated reduced effective gain, decreased phoneme recognition, word recognition, and performance in noise, with the most significant impact observed for soft speech inputs.

Telehealth, or the delivery of healthcare services from a distance, has historically been used to provide care to underserved populations and to those unable to visit a healthcare center. During the ongoing global COVID-19 pandemic, some providers of tinnitus healthcare services incorporated telehealth into their clinical protocols to allow for continued care for their patients while adhering to social distancing guidelines and safety measures. Bothersome tinnitus can negatively impact one's quality of life. Telehealth has been instrumental in treating this debilitating problem in a time when in-person care has not been easily available. The case of a patient with tinnitus is examined to demonstrate the use of a hybrid delivery model utilizing telehealth and in-person interactions to assess and manage her bothersome tinnitus. In-person services were used for audiological assessments and fitting of treatment devices, while telehealth was utilized for counseling, education, and remote programming of her treatment devices. This combined approach, which has allowed the patient to continue receiving care safely during the pandemic, can be continued for future care. Telehealth offers several advantages to patients and providers alike. While the COVID-19 pandemic will hopefully come to an end, telehealth services for tinnitus management may be here to stay.

Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive, neuromodulating technique for brain hyperexcitability disorders. The objective of this paper is to discuss the mechanism of action of rTMS as well as to investigate the literature involving the application of rTMS in the treatment of tinnitus. The reviewed aspects of the protocols included baseline evaluation, the total number of sessions, frequency and the total number of stimuli, the location of treatment, and the outcome measures. Even with heterogeneous protocols, most studies utilized validated tinnitus questionnaires as baseline and outcome measures. Low frequency (1 Hz) stimulation throughout 10 consecutive sessions was the most widely used frequency and treatment duration; however, there was no consensus on the total number of stimuli necessary to achieve significant results. The auditory cortex (AC) was the most targeted location, with most studies supporting changes in neural activity with multi-site stimulation to areas in the frontal cortex (FC), particularly the dorsolateral prefrontal cortex (DLPFC). The overall efficacy across most of the reviewed trials reveals positive statistically significant results. Though rTMS has proven to impact neuroplasticity at the microscopic and clinical level, further studies are warranted to demonstrate and support the clinical use of rTMS in tinnitus treatment with a standardized protocol.
