Purpose: To determine (a) changes in the Tinnitus Handicap Questionnaire (THQ) for patients using cochlear implants, (b) differences between patients who receive total or partial relief, and (c) identifiable characteristics of those who report tinnitus after implantation.
Method: Pre- and postoperatively, 244 adults were administered the THQ when they reported tinnitus.
Results: Of the 153 patients who had tinnitus preoperatively, 94 (61%) patients reported total suppression and 59 (39%) reported a partial reduction. In 91 patients who did not have tinnitus before implantation, 11 (12%) reported tinnitus postimplantation. The THQ score decreased from 41% preimplant to 30% postimplant. The largest reductions involved social handicap and hearing. Patients with a more severe hearing loss might be more likely to experience an exacerbation of their tinnitus. We were not able to clearly identify differences between patients who received total or partial relief and the characteristics of patients who reported tinnitus after implantation. Those who acquired tinnitus had the shortest duration hearing loss (5.6 years) and were the oldest (63 years). The average THQ score of patients getting tinnitus was 29%.
Conclusions: Most tinnitus patients benefit from receiving a cochlear implant.

Evaluation and analysis of the transmission route of sigmoid sinus tinnitus by HRCT of the temporal bone: A retrospective analysis.

Objective: This study aims to analyze anatomical parameters of the transmission route of sigmoid sinus tinnitus (SST) to explore its mechanism and speculate on possible responsible anatomical abnormalities.
Methods: Clinical data were retrospectively collected from SST and sigmoid sinus wall dehiscence (SSWD) patients suggested by temporal bone high resolution computed tomography (HRCT), with and without tinnitus, at the First Affiliated Hospital of Chongqing Medical University from January 2015 to August 2022. Patients were divided into SSWD tinnitus ( = 61), and non-tinnitus ( = 60) groups based on HRCT features.

Purpose: Tinnitus is considered a neurological disorder affecting both auditory and nonauditory networks. This study aimed to investigate the structural brain covariance network in tinnitus patients and analyze its altered topological properties.
Materials: Fifty three primary tinnitus patients and 67 age- and sex-matched healthy controls (HCs) were included.

The occurrence and persistence of tinnitus result from the interaction of multiple neural networks. This study aims to explore the alterations in brain network topology associated with the transition of tinnitus from recent-onset to chronic. Twenty-eight patients with chronic tinnitus, 28 patients with recent-onset tinnitus and 28 sex- and age-matched healthy controls (HC) were enrolled in this study.

Objectives: Due to the absence of objective diagnostic criteria, tinnitus diagnosis primarily relies on subjective assessments. However, its neuropathological features can be objectively quantified using electroencephalography (EEG). Despite the existing research, the pathophysiology of tinnitus remains unclear.

Low frequency noise (LFN) of unknown origin can be disturbing, especially at night, and affect sleep and relaxation. If reduction of the LFN is impossible, adding sound can mask the troubling noise or detract attention from it to reduce distress. To assess the effectiveness of this, a survey was set up consisting of three questionnaires: the first when a person requested a masking sound and follow-ups after 1 and 3 months.
