Condylar resorption of the temporomandibular joint: how do we treat it?

Abstract

Condylar resorption (CR) is a common sequela of some temporomandibular joint (TMJ) abnormalities. CR can result in jaw deformities and dysfunction, malocclusion, pain, headaches, and airway obstruction. Most cases can be classified into 1 of 4 categories based on cause: (1) adolescent internal CR; (2) reactive (inflammatory) arthritis; (3) autoimmune and connective tissue diseases; and (4) other end-stage TMJ pathologic abnormality. MRI is helpful in differentiating the cause and defining treatment options. This article presents the nature and progression of the different TMJ CR pathologic abnormalities, clinical and imaging characteristics, and treatment options to produce predictable and stable outcomes.
