“…This condition represents an uncommon finding in tinnitus patients; published reports indicate that 85-96% of the patients with tinnitus present with some level of hearing loss [König et al, 2006;Roberts et al, 2010;Ryan and Bauer, 2016;Shore et al, 2016], and only 8-10% have normal hearing [Shim et al, 2009;Modh et al, 2014;Plack et al, 2014]. However, on the one hand, the AAO classification is widely recognized and used under a clinical perspective, but on the other hand, it does not include hearing loss above 3 kHz and does not highlight asymmetry.…”

Somatosensory Tinnitus: Correlation between Cranio-Cervico-Mandibular Disorder History and Somatic Modulation

et al. 2016

In a subpopulation of patients, tinnitus can be modulated by movements of the jaw or head and neck due to complex somatosensory-auditory interactions. In some of these subjects, tinnitus could be related to an underlying temporomandibular (TMJ) or craniocervical (NECK) dysfunction that, if correctly identified, could streamline treatment and increase chances of tinnitus improvement. However, it is still unclear whether somatic modulation of tinnitus could be used as a screening tool for identifying such patients. In this study, we included 310 tinnitus patients with normal hearing, no psychiatric comorbidities, and a positive history of TMJ and/or NECK dysfunction and/or a positive modulation of tinnitus to evaluate the characteristics of somatic modulation, investigate the relationship between positive history and positive modulation, and identify factors most strongly associated with somatic modulation. Tinnitus modulation was present in 79.67% of the patients. We found a significant association within the same subjects between a positive history and a positive tinnitus modulation for the same region, mainly for TMJ in unilateral tinnitus patients and for TMJ + NECK in bilateral tinnitus patients. A strong correlation between history and modulation in the same somatic region within the same subgroups of subjects was also identified. Most TMJ maneuvers resulted in an increased loudness, while NECK maneuvers showed an increase in tinnitus loudness in about 59% of cases. High-pitched tinnitus and male gender were associated with a higher prevalence of modulation; no differences were found for tinnitus onset, Tinnitus Handicap Inventory score, and age. In this paper, we report a strong association between history and modulation for the same regions within the same patients; such an association should always be investigated to improve chances of a correct diagnosis of somatosensory tinnitus.

“…In a previous study of 18 patients who showed normal hearing in PTA up to 8 kHz, 12 patients (66.7%) with tinnitus experienced a higher hearing threshold on the affected side in the extended high-frequency band compared with that in a control group of the same age and sex [Shim et al, 2009]; therefore, it is necessary to test PTA beyond 8 kHz to obtain an exact diagnosis of somatic tinnitus. For this reason, patients included in the ST group were only those with symmetric hearing ability (within 10 dB HL difference) in whole frequency of PTA that included 10, 12, 14, 16, 18 and 20 kHz, if the hearing threshold was below 20 dB HL in both ears at less than 8 kHz.…”

Aims:To compare the clinical characteristics of tinnitus among patients with somatic tinnitus (ST), otic tinnitus with somatic modulation (OT+) and otic tinnitus without somatic modulation (OT-), and to examine differences in somatic modulation between patients with ST and OT+. Methods: We retrospectively reviewed the medical records of 65 patients with unilateral tinnitus and classified the patients into three groups: ST (n = 24), OT+ (n = 21) and OT-(n = 20). Results: Only one difference in clinical characteristics was found between the OT+ and OT-groups. Maneuvers related to the temporomandibular joint showed the highest frequency of somatic modulation in both the ST and OT+ groups. There was no significant difference between the ST and OT+ groups with regard to the rate of somatic modulation or the rate of increase or decrease of tinnitus among all aspects of somatic testing. Conclusions: The presence or absence of somatic modulation does not influence the clinical characteristics of otic tinnitus, and the somatosensory-auditory interaction is a general auditory physiologic phenomenon.

“…[1][2][3] The severity of tinnitus commonly increases with the degree of hearing loss, and the pitch of tinnitus often coincides with the frequency of the lesion or is just below the precipitous edge of the lesion. 4,5 These findings demonstrate that damage to cochlear hair cells plays a crucial role in the pathogenesis of tinnitus.…”
