There are many causes of headaches and they can be very challenging problems for a clinician to diagnose and treat. Masticatory myalgia can mimic the location, manifestation, and intensity of true vascular migraine headaches.
Myogenic head pain is usually caused by a discrepancy in one's dental occlusion related to their condylar position which then results in hyperactivity of the masticatory muscles. Internal derangements of the temporomandibular joints can cause pain of the joint area itself or refer pain to regions of the head. Botulinum injections can be an effective treatment option for chronic myogenic head pain that is unresponsive to primary treatments. Many people have some degree of damage to their temporomandibular joints that manifest as popping, clicking, or grinding noises. It is imperative that it be determined whether a disc displacement occurs at the lateral or medial pole of the condylar head before providing any type of irreversible dental treatment, including equilibration, orthodontics, prosthodontics, or jaw surgery. Because joint disorders are progressive, all popping joints should be properly evaluated regardless of whether they are painful.
There is arguably no other area in dental medicine with more confusion and disagreement than TMJ disorders in not only the treatment but the diagnosis. With the litigious nature of today's society, why burden yourself with the responsibility of this complex problem? Whether it is the initial manifestation of a problem, a patient that is unresponsive to treatment, or an acute injury, we are here to help you and your patient.
Radiographic evaluation is very helpful in the diagnostic process and cone beam CT technology makes accessibility to low cost, low radiation CT scans.
Magnetic Resonance Imaging (MRI) is one of the most important diagnostic tools that we have in evaluation and diagnoses of TMJ pathology. In a previous study, we evaluated 25 patients who had bilateral TMJ displaced articular discs and underwent double jaw maxillomandibular advancement surgery, with an average advancement of 9 mm at point B but the TMJs were not addressed so the articular discs remained anteriorly displaced. FIGURE 13: A) In closed position, the condyle is positioned posterior in the fossa and the disc is anteriorly displaced. FIGURE 14: A) Sagittal view of anteriorly displaced disc, B) In this coronal view the articular disc is laterally displaced.


FIGURE 15: The articular disc is anteriorly displaced and significantly deformed, degenerated, and non- reducing rendering it non-salvageable. FIGURE 16: In this case of condylar hyperplasia Type 1, the condyle is growing vertically at an accelerated rate that is faster than the posterior ligament attachment can migrate upward, thus pulling the disc posterior to the condyle.
FIGURE 18: MRI demonstrates a repositioned articular disc using the Mitek anchor technique, with the disc in a normal position. FIGURE 19: MRI of right TMJ shows osteochondroma with large exophytic growth of the anterior aspect of the condyle (CH Type 2Ah).
FIGURE 20: T2 MRI of right TMJ with reactive arthritis and significant condylar resorption. FIGURE 21: MRI of left condyle with perforation of the bilaminar tissue posterior to the anterior disc.
FIGURE 22: Coronal view showing a synovial cyst overlying the superior and lateral aspect of the condyle. Total temporomandibular joint (TMJ) replacement entails surgical replacement of the TMJ with a total joint prostheses as well as orthognathic surgery. Our office is located on the campus of Baylor University Medical Center in the Worth Street Tower. The internal joint problem most often found is displacement of the meniscus (disc) to varying degrees. The noises are caused by an anterior displacement of the cartilage disc that is normally interposed between the condylar head and the glenoid fossa.
The prognosis of a medial pole displacement is much poorer than one at the lateral pole due to the fact that the loading of the joint occurs at the medial pole. Ignoring early signs can prevent the opportunity to correct or stabilize a displacement and thus lead to a more serious problem. It may be acceptable to have differing opinions on how to treat any condition of the body but there should be only one correct diagnosis. Presurgery, 36% of the patients had pain or discomfort involving the TMJ, head and jaw area. B) On opening the condyle and disc translate down and forward beneath the articular eminence.


On opening, there should be good translation of the condyle and the articular disc forward and positioned beneath the articular eminence.
The disc is in position but with a reactive pannus (grey tissue) surrounding the disc that destroys the disc, condyle, and articular eminence. The inflammatory process is noted to occupy a significant volume between the fossa and condyle. Almost always these perforations are posterior to the posterior band of the articular disc or lateral to the disc and rarely do perforations occur through the disc itself. If a patient presents with pain of the facial, temporal, masseter, or occipital region it is often myogenic in nature and caused by a hyperactivity of these muscles due to a TMJ disorder.
Unfortunately, there is a tremendous amount of false advertising by dentists who claim to treat migraines by the use of bite splints or TMJ therapy.
The ligaments that position the disc can become stretched or torn from even a very minor injury which can then allow the TMJ disc to become displaced.
In addition to which portion of the disc is displaced, the medial or lateral direction of the displacement is also important to know. Closed locks usually represent a more severe problem and need aggressive early intervention. Importantly it can help in the diagnosis of TMJ pathology in the silent joint where disc displacement and degenerative changes can be present but may not make noise or be particularly uncomfortable or painful but yet result in poor outcomes if only orthognathic surgery is performed. The popping noise that is heard is from the disc reducing back onto the condylar head during opening or from it slipping off when closing. The direction and degree of a displacement as well as the shape and integrity of the disc determine the diagnosis, prognosis, and treatment.
