3D Anatomy of Human Otomandibular Soft Tissues and its Significance for the Origin of the Temporomandibular Joint Articular Disc
Understanding the ligamentous and muscular connections between the temporomandibular joint (TMJ) and middle ear ossicles is important for health sciences and ENT training and diagnosing comorbidity between TMD and otological pain, as well as exploring the developmental and evolutionary origins of th...
