“…Patients with somatic tinnitus have shown different characteristics, being younger, with higher prevalence of female gender and unrelated to hearing loss (somatic tinnitus patients often have normal hearing) or tinnitus severity [58][59][60][61][62] . The most common musculoskeletal conditions that underlie somatic tinnitus are temporomandibular joint (TMJ) and cervical spine (NECK) disorders 43,44,52 .…”

Modulation of tinnitus characteristics such as pitch and loudness has been extensively described following movements of the head, neck and limbs, vertical or horizontal eye gaze, pressure on myofascial trigger points, cutaneous stimulation of the hands, electrical stimulation of the median nerve, and transcranial direct current stimulation. Modulation of tinnitus follows complex interactions between auditory and somatosensory afferents and can be favored by underlying somatic disorders. When tinnitus appears to be preceded or strictly linked to a somatic disorder, and therefore related to problems of the musculoskeletal system rather than of the ear, it is defined somatic tinnitus. A correct diagnosis and treatment of somatic disorders underlying tinnitus play a central role for a correct management of somatic tinnitus. However, the identification of somatic tinnitus may be complex in some cases. In this paper, after a general review of the current evidences for somatic tinnitus available in the literature, we present and discuss some cases of patients in which somatic modulation of tinnitus played a role-although different from case to case-in their tinnitus, describing the diagnostic and therapeutic approaches followed in each individual case and the results obtained, also highlighting unexpected findings and pitfalls that may be encountered when approaching somatic tinnitus patients.

“…in tinnitus, the role of hyperactive muscle tissues stimulated through trigger points has been noted [8][9][10]. strong spasms of the temporomandibular joint (tMJ), head and neck and extremities, vertical or horizontal eye movements and activated trigger points may temporarily modulate the psychoacoustic features of tinnitus [11,12]. neuroplasticity seems to play a central role in this modulation capability, suggesting that aberrant interactions between sensory modalities, sensory-motor systems and neurocognitive and neuromuscular networks may contribute to the development of somatosensory tinnitus [11].…”

A -study Design, B -Data collection, C -statistical analysis, D -Data interpretation, E -Manuscript Preparation, F -literature search, G -Funds collection Background. structures of temporomandibular joints and ear have a common phylogenetic origin. Muscular imbalance in the area of masticatory muscles may lead to tinnitus. Objectives. a comparison of muscular tension and masticatory muscles asymmetry between women with tinnitus and without tinnitus. Material and methods. From a group of 96 examined responders, we found 32 women (aged 22 ± 2 years) who exhibited no temporomandibular joint disorders and who had not been treated otolaryngologically. the examined women were then placed within two groups: with tinnitus (16 people) and without tinnitus (16 people). next, we examined the muscular activity in the temporomandibular muscles by way of seMG at rest, when the teeth were clenched and when the mouth is opened maximally. to assess muscular asymmetry, the asymmetry index was used. Results. Despite the lower bioelectrical muscular tension of masticatory muscles at rest and during the examined functions in people with tinnitus, the results were not important statistically (p > 0.05). however, we observed crucial statistical differences in masseter muscle asymmetry in people with tinnitus when clenching teeth (p = 0.042), and in the number of people with muscle asymmetry in the area of the masticatory muscles at rest (p = 0.012) and when teeth are clenched (p = 0.013), in comparison to a healthy group. Conclusions. there is a relationship between changes in the asymmetry index of the masticatory muscles and the occurrence of tinnitus. in order to confirm the results, we recommend further examination in this area and longer observation time.

Several studies have demonstrated the neural correlates of chronic tinnitus. However, we still do not understand what happens in the acute phase. Past studies have established Zwicker tone (ZT) illusions as a good human model for acute tinnitus. ZT illusions are perceived following the presentation of a notched noise stimulus, that is, broadband noise with a narrow band‐stop filter (notch). In the current study, we compared the neural correlates of the reliable perception of a ZT illusion to that which is not. We observed changes in evoked and total theta power in wide‐spread regions of the brain particularly in the temporal‐parietal junction, pregenual anterior cingulate cortex/ventromedial prefrontal cortex (pgACC/vmPFC), parahippocampus during perception of the ZT illusion. Furthermore, we observe that increased theta power significantly predicts a gradual positive change in the intensity of the ZT illusion. Such changes may suggest a malfunction of the sensory gating system that enables habituation to redundant stimuli and suppresses hyperactivity. It could also suggest a successful retrieval of the memory of the missing frequencies, resulting in their conscious perception indicating the role of higher‐order processing in the mechanism of action of ZT illusions. To establish a more concrete relationship between ZT illusion and chronic tinnitus, future longitudinal studies following up a much larger sample of participants who reliably perceive a ZT illusion to see if they develop tinnitus at a later stage is essential. This could inform us if the ZT illusion may be a precursor to chronic tinnitus.
