Popis: Abstract Background Disorders affecting the temporomandibular joint (TMJ), related structures, and the masticatory muscles are called temporomandibular disorders (TMD). The two most typical symptoms are mouth opening restriction and pain. Costen noted the connection between TMD and tinnitus in 1934. These conditions are brought about by the shared structures that connect the TMJ and the auditory apparatus (bones and muscles) through a shared innervation source and specific ligaments. Wright addresses Costen ideas, which suggest that otological symptoms of TMD could be caused by auriculotemporal nerve damage, Eustachian tube restriction, or other factors causing an incorrect intratympanic pressure adjustment. Methods Cross-sectional observation was regulated at Oral and Maxillofacial Surgery Department, Faculty of Dentistry, Cairo University. The following are the inclusion criteria: patients with a TMD diagnosis and those older than 16 years old. The following conditions are excluded: neurological or oncological disorders, ear infection, and a history of face trauma. Results The total number was 196 patients, 63.8% females and 36.2% males. A total of 76.5% had bilateral joint pain, and 21.9% had unilateral joint pain. While 70.4% had bilateral muscle pain, 18.9% had unilateral muscle pain. A total of 91.8% had mild tinnitus, while 8.2% had moderate tinnitus. Conclusion In this study, 8.2% of patients complaining of tinnitus had severe tinnitus, while 91.8% had mild tinnitus.
