Patients with any type of temporomandibular disorder (TMD) may have several symptoms in their temporomandibular joints, masticatory muscles and associated structures, and may have otological symptoms such as tinnitus, ear fullness, ear pain, hearing loss, hyperacusis, and vertigo, which may be due to the anatomical proximity between the temporomandibular joint, muscles innervated by the trigeminal nerve, and ear structures. Objective: This study found a prevalence of ear complaints described in the medical records of patients (n = 485) at the Center for Diagnosis and Treatment of the Temporomandibular Joint and Dental-Facial Functional Alterations at Tuiuti University of Paraná (CDATM/UTP), with TMD evaluated by the Research Diagnostic Criteria/Temporomandibular Disorders (RDC/ TMD). ⋯ These data support the correlation between temporomandibular disorders and otological symptoms, even without being caused directly by the ear.
