- Original description
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.Read full original descriptionShow less
Investigation of the Interaction Between Temporomandibular Joint and Tinnitus Using CBCT and Audiological Methods: A Prospective Cross-Sectional Study
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.
Inclusion: Patients aged 18 years and older; Patients presenting with otological symptoms such as tinnitus and ear pain; Patients diagnosed with Temporomandibular Disorders (TMD) based on clinical and radiographic examination; Patients who have been referred for CBCT imaging as part of their routine diagnostic process for TMD; Willingness to provide written informed consent to participate in the study.
Exclusion: Previous history of temporomandibular joint surgery or major maxillofacial trauma; History of chronic otitis media or other middle ear pathologies that could cause hearing loss or tinnitus; Presence of systemic metabolic bone diseases or inflammatory rheumatic diseases (e.g., Rheumatoid Arthritis); History of malignancy in the head and neck region; Neurological or psychological disorders that would prevent cooperation during clinical and audiological examinations; Presence of objective tinnitus (e.g., vascular or muscular origin); Pregnancy (due to CBCT imaging contraindication).
