Commonly, plain and panoramic X-ray radiographies are used to determine the relative position of the mandibular condyle. If a complex or unusual injury is suspected, three-dimensional computed tomography is most reliable in diagnosing dislocation and possibly associated fractures or soft tissue injuries.In case of dislocations resulting from high-energy trauma, attention must also be paid to possible other injuries, particularly blunt or indirect trauma to the skull and cervical spine. Acutely life-threatening conditions need to be ruled out or treated in first line. For superior jaw dislocation in particular, serious intracranial complications such as epidural hematoma are possible and must be recognized and managed to prevent disability or even death. Therefore, neurological status has to be examined in patients with complex dislocations involving temporal bone fractures. Hearing deficits on the injured side may indicate damage to structures of the ear. Treatment
Most temporomandibular disorders (TMDs) are self-limiting and do not get worse. Simple treatment, involving self-care practices, rehabilitation aimed at eliminating muscle spasms, and restoring correct coordination, is all that is required. Nonsteroidal anti-inflammatory analgesics (NSAIDs) should be used on a short-term, regular basis and not on an as needed basis. On the other hand, treatment of chronic TMD can be difficult and the condition is best managed by a team approach; the team consists of a primary care physician, a dentist, a physiotherapist, a psychologist, a pharmacologist, and in small number of cases, a surgeon.
(S)-Oxybutynin has not been clinically tested for its spasmolytic effects, but may be clinically useful for the same indications as the racemate, without the unpleasant anticholinergic side effects. Brand names
Oxybutynin is available by mouth in generic formulation and under the brand names Ditropan, Lyrinel XL, Ditrospam, Kentera, and Aquiette, as a transdermal patch under the brand name Oxytrol, and as a topical gel under the brand name Gelnique. See also
