The aim of this systematic review was to evaluate the prevalence of tinnitus in patients with temporomandibular disorders (TMD) and the possible effects of TMD treatment on tinnitus symptoms. A search of the PubMed, Web of Science, and Cochrane databases from inception of each database up to January 2017 found 222 articles. After independent screening of abstracts by two of the authors, we assessed 46 articles in full text. The inclusion and exclusion criteria reduced these to 25 articles of which 22 studies reported prevalence based on 13,358 patients and 33,876 controls, and eight studies reported effect of TMD treatment on tinnitus based on 536 patients and 18 controls. The prevalence of tinnitus in patients with TMD varied from 3.7% to 70% (median 42.3%) whereas the prevalence in control groups without TMD varied between 1.7% and 26% (median 12%). The eight treatment studies, indicated that treatment of TMD symptoms may have a beneficial effect on severity of tinnitus. However, only one treatment study included a control group, meaning that the overall level of evidence is low. The finding that tinnitus is more common in patients with TMD means that it can be regarded as a comorbidity to TMD. However, in view of the lack of evidence currently available, further well-designed and randomized studies with control groups are needed to investigate whether possible mechanisms common to tinnitus and TMD do exist and whether TMD treatment can be justified to try to alleviate tinnitus in patients with TMD and comorbidity of tinnitus.

- Is there a higher prevalence of tinnitus in patients with temporomandibular disorders? A systematic review and meta-analysis. [Review]

The aim of this study was to determine if there exists a higher prevalence of tinnitus in patients with temporomandibular disorders (TMDs) than in patients without TMDs. A systematic review was conducted in PubMed/MEDLINE for articles published between January 1992 and April 2018 in accordance with the PRISMA statement. Studies were included in this review only if they assessed TMDs using the research diagnostic criteria (RDC)/TMD or DC/TMD. A total of five studies were included in the systematic review, and a random effects meta-analysis of three of the studies was conducted. In all of the selected studies, the prevalence of tinnitus was higher in patients with TMDs (35.8% to 60.7%) than in patients without TMDs (9.7% to 26.0%). The odds ratio of suffering from tinnitus among patients with TMDs was 4.45 (95% CI 1.64-12.11. P=0.003). Thus, despite the limitations of the included studies, this review demonstrates that the prevalence of tinnitus in TMD patients is significantly higher than that in patients without TMD.

- Audiometric and cVEMP Thresholds Show Little Correlation With Symptoms in Superior Semicircular Canal Dehiscence Syndrome. [Journal Article]
- ONOtol Neurotol 2018 Aug 17
- CONCLUSIONS: While threshold audiometry and cVEMP are important tools to diagnose SCD and monitor surgical outcomes, these measures showed no significant correlation with vestibular and most auditory symptoms or their severity.

Tinnitus is a common clinical symptom. Researches have shown that fractal sound can effectively treat tinnitus. But current fractal sound is usually synthesized based on constant notes via fractal algorithm, which lead to monotony of synthesized fractal sound. So it is difficult to achieve personalized match. Clinical datas have confirmed that it is common to match tinnitus sound with nature sound and it has a good effect on regulating negative emotion and relieving tinnitus via some natural sound. Therefore, a new method of personalized synthesizing tinnitus rehabilitation sound based on iterative function system (IFS) fractal algorithm is proposed in this paper. This method firstly generates personalized audio library based on natural sound, then tinnitus rehabilitation sound is synthesized via IFS fractal algorithm. Simulation results show that rehabilitation sound in this paper can meet the basic requirements of tinnitus therapy sound and can match tinnitus sound by controlling personalized audio library. So it has reference significance to the treatment of tinnitus sound therapy.
- Tinnitus distress is associated with enhanced resting-state functional connectivity within the default mode network. [Journal Article]
- NDNeuropsychiatr Dis Treat 2018; 14:1919-1927
- CONCLUSIONS: Chronic tinnitus patients showed disrupted FC patterns within the DMN regions which are correlated with tinnitus distress. Increased resting-state connectivity pattern of the DMN may play a pivotal role in neuropathological features underlying chronic tinnitus.
- Pain-free and pain-controlled survival after sectioning the nervus intermedius in nervus intermedius neuralgia: a single-institution review. [Journal Article]
- JNJ Neurosurg 2018 Aug 17; :1-8
- CONCLUSIONS: In this retrospective review, sectioning of the NI produced no major complications, such as permanent facial weakness or deafness, and was effective for patients when performed in addition to other procedures. After sectioning of the NI, patients experienced 4.8 years pain free and experienced 6.2 years of less pain than before surgery. Alone, sectioning of the NI was not effective. The pathophysiology of NIN is not entirely understood. It appears that neurovascular compression plays only a minor role in the syndrome and there is a high degree of overlap with TN.
- The Impact of Vitamin D Deficiency on Retinopathy and Hearing Loss among Type 2 Diabetic Patients. [Journal Article]
- BRBiomed Res Int 2018; 2018:2714590
- CONCLUSIONS: Vitamin D deficiency is considered as a risk factor for diabetic retinopathy and hearing loss among diabetic patients. Meanwhile, hyperglycemia could be considered as a modifiable risk factor for diabetic retinopathy; tight glycemic control may be the most effective and important therapy for improving quality of life and substantially reducing the incidence of retinopathy and in T2DM patients.
- Characterization of vertigo and hearing loss in patients with Fabry disease. [Journal Article]
- OJOrphanet J Rare Dis 2018 Aug 15; 13(1):137
- CONCLUSIONS: Hearing loss and vertigo show a high prevalence in FD. While hearing loss seems due to a cochlear lesion, peripheral vestibular as well as central nervous pathologies cause vertigo. Thus, both the site of lesion and the pathophysiological patterns seem to differ.
- Canadians vulnerable to workplace noise. [Journal Article]
- HRHealth Rep 2018 Aug 15; 29(8):9-17
- CONCLUSIONS: A large percentage of workers exposed to noisy workplaces were vulnerable because hearing protection was neither required nor routinely used. Further work is required to assess whether this reflects gaps in health and safety legislation or its implementation.

Tinnitus is a problem that affects a diverse range of people. One common trait amongst tinnitus sufferers is the presence of hearing loss, which is apparent in over 90% of the cohort. It is postulated that the remainder of tinnitus sufferers have hidden hearing loss in the form of cochlear synaptopathy. The loss of hearing sensation is thought to cause a reduction in the bottom-up excitatory signals of the auditory pathway leading to a change in the frequency of thalamocortical oscillations known as Thalamocortical Dysrhythmia (TCD). The downward shift in oscillatory behaviour, characteristic of TCD, has been recorded experimentally but the underlying mechanisms responsible for TCD in tinnitus subjects cannot be directly observed. This paper investigates these underlying mechanisms by creating a biologically faithful model of the auditory periphery and thalamocortical network, called the central auditory processing (CAP) model. The proposed model replicates tinnitus related activity in the presence of hearing loss and hidden hearing loss in the form of cochlear synaptopathy. The results of this work show that both bottom-up and top-down changes are required in the auditory system for tinnitus related hyperactivity to coexist with TCD, contrary to the theoretical model for TCD. The CAP model provides a novel modelling approach to account for tinnitus related activity with and without hearing loss. Moreover, the results provide additional clarity to the understanding of TCD and tinnitus and provide direction for future approaches to treating tinnitus.
