Conditions
Treated with Partial Temporomandibular Joint Replacement:
Partial
temporomandibular joint replacement may be performed in cases of trauma or
infection, or tumor, ankyloses, dislocation, disc herniation or osteoarthritis
of the temporomandibular joint.
Non-surgical
alternatives to partial temporomandibular joint replacement include ice
therapy, dietary restrictions, physical therapy, non-steroidal
anti-inflammatory medication and use of a bite guard. Total temporomandibular
joint replacement is a surgical alternative to the procedure.
Anesthesia with Partial
Temporomandibular Joint Replacement:
Partial
temporomandibular joint replacement is performed under general anesthesia,
which means that the patient is asleep and completely unaware during the
procedure.
Potential
Complications from Partial Temporomandibular Joint Replacement:
Possible
risks following partial temporomandibular joint replacement include swelling,
bleeding, infection, pain and a negative reaction to the anesthesia. It is also
possible to experience partial hearing loss, vertigo and cranial nerve damage.
The patient may require an occlusal splint.
Prognosis after Partial
Temporomandibular Joint Replacement:
The
prognosis for a positive end result following partial temporomandibular joint
replacement is good. However, many lifestyle changes are required after the procedure.
Recovery from Partial
Temporomandibular Joint Replacement:
Total
recovery from partial temporomandibular joint replacement takes several months.
