temporomandibular joint involvement
Also written as: TMJ — temporomandibular joint
Inflammation of the jaw joints in pediatric arthritis, often asymptomatic but potentially causing growth disturbances and functional problems.
Full Definition
Temporomandibular joint (TMJ) involvement in pediatric inflammatory arthritis is common but frequently overlooked due to its often asymptomatic nature. This condition can lead to significant complications including facial asymmetry, micrognathia (small jaw), dental malocclusion, and restricted mouth opening. TMJ arthritis may be the only manifestation of systemic disease or occur as part of polyarticular involvement. Early detection requires specific clinical assessment and often advanced imaging, as routine examination may miss subtle signs. Treatment aims to control inflammation and prevent growth disturbances that can have lasting cosmetic and functional consequences.
Usage
Usage note: Often abbreviated as TMJ; may require specialized imaging and dental/orthodontic collaboration for comprehensive care.
