Concomitant Temporomandibular Joint (TMJ) &
Orthognathic (Corrective Jaw) Surgery
Diagnosis And Treatment Planning
Temporomandibular joint (TMJ) disorders/pathology and jaw deformities commonly co-exist; therefore require an accurate diagnosis and concomitant TMJ and orthognathic (corrective jaw) surgery.

The temporomandibular joints (TMJs), jaw joints, are the foundation for jaw position, facial growth and development, function, dental occlusion, facial balance and comfort. If the TMJs are not stable and healthy (non-pathological), patients requiring orthognathic (corrective jaw) surgery may have unsatisfactory outcomes relative to function, esthetics, dental occlusal and skeletal stability, and pain. A review of 1369 consecutive TMJ patients referred to Dr. Larry Wolford’s practice revealed an age range of 8 to 76 years at initial evaluation, with 78% of the patients female and 22% male. Interestingly, 69% of the patients reported the onset of their TMJ problems during the teenage years. Therefore, TMJ pathology predominantly develops in teenage females, although may not manifest itself until much later.
TMJ disorders/pathology and dentofacial deformities commonly co-exist. The TMJ pathology may be the causative factor of the jaw deformity, develop as a result of the jaw deformity, or the 2 entities develop independent of each other. The most common TMJ pathologies that can adversely affect jaw position, dental occlusion, as well as corrective jaw surgical outcomes include:
- TMJ Articular Disc Dislocation: Dislocation of the TMJ disc, which is positioned between the two bones that form the jaw joint.
- Adolescent Internal Condylar Resorption (AICR) of the TMJ: “Cheerleaders Syndrome” a specific condition that affects the jaw joints (temporomandibular joints or TMJs) and most commonly occurs in teenage girls.
- Reactive Arthritis of the TMJ: Frequently seen in children with chronic arthritis.
- Mandibular Condylar Hyperplasia: Slowly progressive unilateral enlargement of the head and neck of the jaw condyle causes crossbite malocclusion, facial asymmetry, and shifting of the midpoint of the chin toward the unaffected side.
- Temporomandibular Joint (TMJ) Ankylosis: The fusing together of the bones forming the joint most frequently caused by poor healing following severe trauma or infection. It can also occur congenitally, or secondary to severe rheumatoid arthritis or to tumors in the area of the TMJ.
- Congenital Deformation or Absence of the Temporomandibular Joint (TMJ): Absence of a jaw joint results in a progressively underdeveloped lower jaw that usually requires a jaw joint (TMJ) implant.
- Connective tissue and autoimmune diseases of the TMJ
- Other end-stage TMJ pathologies.1
These Temporomandibular Joints (TMJ) conditions are often associated with:
- Dentofacial deformities
- Dental malocclusion
- TMJ pain
- Myofascial pain
- TMJ and jaw functional impairment
- Ear symptoms
- Sleep apnea
Patients with these conditions may benefit from corrective surgical intervention including temporomandibular joint (TMJ) and orthognathic (corrective jaw) surgery. Many clinicians may have difficulty identifying the presence of a TMJ condition, diagnosing the specific TMJ pathology, and selecting the proper treatment for that condition. This website should improve the clinician’s diagnostic and treatment planning skills and give patients better understanding of their disorders and how to deal with them.
Asymptomatic TMJ pathology/disorders
Although most TMJ patients have associated symptoms, approximately 25% of patients with TMJ pathology/disorders will be asymptomatic. These patients are diagnostically challenging when undergoing orthognathic surgery because the TMJ pathology may not be recognized or treated appropriately, resulting in a poor treatment outcome with potential redevelopment of the skeletal and occlusal deformity by condylar resorption or overdevelopment as well as initiation of worsening pain, headaches, jaw and TMJ dysfunction as well as other TMJ symptoms.
Jaw surgery in the presence of displaced TMJ articular discs
The literature has clearly demonstrated the adverse affects of performing only orthognathic surgery in the presence of displaced TMJ articular discs. (2) Our research studies (3,4) show that in presence of TMJ displaced discs that are not corrected, but the maxilla and mandible are advanced, an average anteroposterior (AP) mandibular relapse of 30% can be expected as well as an 84% chance of developing or worsening of TMJ pain, facial pain, and headaches. Accurate diagnosis and proper surgical intervention for the specific TMJ pathologies that may be present in orthognathic surgery patients will provide highly predictable and stable results.
