Loose Intra-articular Body in the Temporomandibular Joint: Case Report of a Successful Conservative Management

Abstract

Loose intra-articular bodies are a rare finding in the temporomandibular joint. Surgical removal of the loose bodies isoften described as the only treatment option; however, it presents possible postoperative complications. The aim of thispaper is to report the successful conservative management of a temporomandibular disorder associated with a singleloose intra-articular body. A 62-year-old woman presented with pain in the right temporomandibular joint andpre-auricular region, limited mouth opening and open-lock episodes. Panoramic radiography and cone-beam computedtomography exams revealed the presence of a single loose body located anterior to the right condyle. Magnetic resonanceimages showed bilateral anterior disc displacement without reduction. A non-invasive approach consisting of an occlusalsplint and low-level laser therapy associated with home-based physical therapy was performed for management ofclinical signs and symptoms. The patient was followed up for 2 years and presented significant pain reduction andimprovement in the range of mandibular movements. The combination of conservative therapies may be an alternativefor surgical intervention to control pain and improve mandibular function in patients with temporomandibulardysfunction associated with a loose body in the temporomandibular joint.
