Temporomandibular joint (TMJ) and dentofacial deformities commonly coexist. The TMJ
disorders may be the causative factor of the jaw deformity or may have developed as
a result of the jaw deformity, or the 2 entities may occur independently of each other.
The TMJs form the foundation for jaw position, function, occlusion, facial balance,
and comfort. If the TMJs are not stable and healthy (nonpathologic), patients requiring
orthognathic surgery may have unsatisfactory outcomes relative to function, aesthetics,
occlusal and skeletal stability, and pain. The most common TMJ disorders that can
adversely affect orthognathic treatment outcomes include (1) articular disc dislocation,
(2) adolescent internal condylar resorption (AICR), (3) reactive arthritis, (4) condylar
hyperplasia, (5) ankylosis, (6) congenital deformation or absence of the TMJ, (7)
connective tissue and autoimmune diseases, and (8) other end-stage TMJ disorders.
These TMJ conditions are often associated with dentofacial deformities, malocclusion,
TMJ pain, headaches, myofascial pain, TMJ and jaw functional impairment, ear symptoms,
and sleep apnea. Patients with these conditions may benefit from corrective surgical
intervention, including TMJ and orthognathic surgery. The difficulty for many clinicians
is in identifying the presence of a TMJ condition, diagnosing the specific TMJ disorder,
and selecting the proper treatment of that condition.
