Sometimes TMD pain can radiate or be referred from its cause (i.e. the TMJ or the muscles of mastication) and be felt as headaches, earache or toothache. [12] Due to the proximity of the ear to the temporomandibular joint, TMJ pain can often be confused with ear pain. [23]
Temporomandibular disorder (TMD, also termed "temporomandibular joint pain-dysfunction syndrome") is pain and dysfunction of the TMJ and the muscles of mastication (the muscles that move the jaw). TMD does not fit neatly into any one etiologic category since the pathophysiology is poorly understood and it represents a range of distinct ...
In humans, the mandible, or lower jaw, is connected to the temporal bone of the skull via the temporomandibular joint. This is an extremely complex joint which permits movement in all planes. The muscles of mastication originate on the skull and insert into the mandible, thereby allowing for jaw movements during contraction.
Oromandibular dystonia is characterized by involuntary spasms of the tongue, jaw, and mouth muscles that result in bruxism, or grinding of the teeth, and jaw closure. These conditions frequently lead to secondary dental wear as well as temporomandibular joint syndrome. In addition, problems with chewing, speaking, and swallowing may result from ...
The immediate symptom can be a loud crunch noise occurring right up against the eardrum. This is instantly followed by excruciating pain, particularly in the side where the dislocation occurred. [citation needed] Short-term symptoms can range from mild to chronic headaches, muscle tension or pain in the face, jaw and neck. [citation needed]
Eagle syndrome (also termed stylohyoid syndrome, [1] styloid syndrome, [2] stylalgia, [3] styloid-stylohyoid syndrome, [2] or styloid–carotid artery syndrome) [4] is an uncommon condition commonly characterized but not limited to sudden, sharp nerve-like pain in the jaw bone and joint, back of the throat, and base of the tongue, triggered by swallowing, moving the jaw, or turning the neck.

The temporalis muscle is covered by the temporal fascia, also known as the temporal aponeurosis. This fascia is commonly used in tympanoplasty, or surgical reconstruction of the eardrum. The temporalis muscle is accessible on the temples, and can be seen and felt contracting while the jaw is clenching and unclenching.
The cause of condylar resorption is unknown, but there are theories. Because condylar resorption is much more likely to occur in young females, hormonal mediation may be involved. Strain on the temporomandibular joint from orthodontics or orthognathic surgery may be related to the condition.
