Abstract
MIRANDA HERNANDEZ, Blanca and MIRANDA VILLASANA, José Ernesto. Temporomandibular joint ankylosis treated with arthroplasty in a patient with reumathoid arthritis: A case report. Rev. Odont. Mex [online]. 2011, vol.15, n.3, pp.163-168. ISSN 1870-199X.
Temporomandibular joint (TMJ) ankylosis is a degenerative disease that produces a limitation of mouth opening, causing problems during feeding, occlusal disharmony, upper way obstruction and facial asymmetry in developing children. It presents a multifactorial aetiology with diverse factors as trauma, infections, inflammatory diseases, radiation-therapy, microsomia, tumors and congenital diseases. Trauma is considered the most common factor. Rheumatoid Arthritis (RA) is a systemic chronic, inflammatory and autoimmune disease affecting diarthroidal joints and frequently a variety of organs. Rheumatoid Arthritis (RA) occurs worldwide, in all ethnic groups, with a prevalence of 0.3% to 1.5% of cases in the population. Females are 2.3 times more likely to be affected than males, the peak onset being between the fourth and sixth decades of life, but it may begin in childhood (JRA) 1,2 or later in life. Temporomandibular joint affects 50 to 60% of all patients with RA a year after the disease has become systemic.3,4 Case report: A 39 year old female patient with RA with a severe mouth opening limitation (4 mm) that had caused her malnutrition. The patient was receiving treatment at the Rheumatology and Maxillofacial Surgery Clinic where surgical procedure was performed carried out (bilateral TMJ arthoplasty and left side coronoidectomy), after the surgery the patient was able to open the mouth 31 mm; in a control appointment 18 months after the surgery there were no signs of recurrence.
