OBJECTIVES This study aims to compare the epidemiological data of three cohorts of dysfunctional patients attending to the Clinical Gnathology Service of Policlinico Umberto I University Hospital - Sapienza University of Rome, in order to highlight the salient characteristics of Temporomandibular disorders (TMD) and patients who are affected, and understand their evolution over time.
Background: Several anatomic relationships between the ear and the TMJ have been proposed to account for the presence of tinnitus during TMD. Most important otomandibular structures are tympanomandibular ligament and discomalleolar ligament. The latter connects the malleus bone of the middle ear and the postero-medial region of the temporomandibular joint.
Objectives: For this reason, the aim of the present paper is to study, on fresh adult cadavers, the frequency of discomalleolar ligaments, its correlation with the middle ear and its role in the ethiology of tinnitus.
