CBCT and Audiological Analysis of the TMJ-Tinnitus Relationship

The aim of this study is to investigate the relationship between Temporomandibular Disorders (TMD) and subjective tinnitus at both morphological and functional levels. Current literature suggests that somatosensory inputs from the temporomandibular joint (TMJ) and masticatory muscles can modulate auditory pathways, a phenomenon known as Somatosensory Tinnitus. However, the specific role of TMJ bone morphology and critical neighboring structures, such as the Petrotympanic Fissure (PTF), in this interaction remains unclear. In this clinical study, patients with tinnitus will undergo a comprehensive evaluation including Cone Beam Computed Tomography (CBCT) to quantitatively analyze condylar morphology and osteoarthritic changes. Additionally, audiological tests will be performed to assess the functional state of the auditory system. This multidisciplinary approach aims to clarify the biological link between TMD and tinnitus, potentially improving diagnostic protocols and highlighting the importance of TMJ stabilization in tinnitus management.
