c. 1600 BCE, Ancient Egypt — Edwin Smith Papyrus descriptions of jaw dislocation and manipulation
The temporomandibular joint and its associated disorders occupied a marginal position in medical thought for most of recorded history, with ancient healers addressing jaw problems primarily through the lens of dislocation and fracture rather than chronic functional disturbance. The condition gained a distinct medical identity only in the twentieth century, when a American otolaryngologist proposed a framework that, though later revised substantially, catalyzed generations of clinical inquiry. Debates over whether the condition was primarily dental, muscular, neurological, or psychological defined much of its contentious historiography.
Historical Narrative
Ancient Egyptian medical papyri, including the Edwin Smith Papyrus dating to approximately 1600 BCE, contained descriptions of jaw injuries and dislocations, with instructions for manual reduction of displaced mandibles. These earliest records addressed acute mechanical problems rather than chronic dysfunction, and the joint itself was understood primarily as a hinge susceptible to trauma. Greek and Roman physicians, including Hippocrates, described techniques for reducing jaw dislocations that remained influential well into the early modern period, with Hippocratic manipulations referenced in surgical texts across medieval Islamic and European traditions.
Galen's anatomical work in the second century CE provided more detailed descriptions of the temporomandibular articulation, though Galenic anatomy was suffused with humoral theory that shaped how physicians understood joint pathology generally. Disorders of the jaw were attributed to imbalances of phlegm or cold humors settling in the joint, and treatments accordingly emphasized warming remedies, purgatives, and dietary adjustments aimed at systemic humoral correction rather than local mechanical intervention.
Medieval Islamic physicians, including Ibn Sina, whose Canon of Medicine organized medical knowledge for centuries, addressed jaw pain and trismus within broader discussions of facial and cranial disorders. Ibn Sina's explanations drew on Galenic humoral frameworks while incorporating his own clinical observations, and his texts were translated into Latin and served as authoritative references in European medical schools through the Renaissance.
The early modern period brought improved anatomical knowledge following Vesalius's landmark corrections to Galenic anatomy in 1543, and subsequent anatomists provided increasingly precise descriptions of the temporomandibular joint's structure. Dental practitioners in the eighteenth and nineteenth centuries began observing connections between tooth loss, malocclusion, and jaw discomfort, though these observations remained anecdotal and were not synthesized into any coherent clinical framework.
The pivotal moment in the syndrome's modern history came in 1934, when James Bray Costen, an American otolaryngologist working in St. Louis, published an influential paper arguing that a constellation of ear, jaw, and facial symptoms arose from improper bite relationships that compressed the joint and impinged on nearby neural and vascular structures. Costen's theory, though grounded in his own clinical observations, rested on anatomical assumptions that subsequent investigators challenged and largely refuted. Nevertheless, his paper provoked intense interest and debate, and the syndrome briefly carried his name in the dental and medical literature of the 1930s and 1940s.
Subsequent decades saw researchers decompose Costen's broad syndrome into competing theoretical frameworks. Dental researchers in the 1950s and 1960s emphasized occlusal factors, generating extensive clinical effort around bite adjustment and prosthetic correction. Simultaneously, investigators influenced by the behavioral sciences proposed that muscle tension arising from psychological stress played a central etiological role, a view that gained traction through the 1970s. The introduction of arthroscopy and advanced imaging technologies in the 1980s allowed researchers for the first time to visualize the joint's internal structures directly, revealing disc displacement patterns that reshaped understanding of the joint's mechanical behavior and complicated earlier explanatory models considerably.
