Clinical indications for simultaneous TMJ and orthognathic surgery

Area of Science:

• Oral and Maxillofacial Surgery
• Orthodontics
• Temporomandibular Joint Disorders

Background:

• Temporomandibular joint (TMJ) conditions encompass a range of pathologies leading to pain, dysfunction, and disability.
• Common TMJ conditions include articular disk dislocation, reactive arthritis, adolescent internal condylar resorption, condylar hyperplasia, osteochondroma/osteoma, and end-stage TMJ pathology.
• These disorders are frequently linked to dentofacial deformities, malocclusion, TMJ pain, headaches, myofascial pain, functional impairment, and otologic symptoms.

Observation:

• Surgical intervention, particularly open joint surgery, offers direct access to the TMJ.
• This approach enables manipulation, repair, removal, and reconstruction of anatomical structures not amenable to non-surgical treatments.
• Combined TMJ surgery and orthognathic surgery can be performed concurrently with high success rates.

Findings:

• The study reviews prevalent TMJ pathologies and their clinical manifestations.
• It details surgical management strategies tailored to specific TMJ conditions and concurrent jaw deformities.
• Open joint surgery is highlighted as a crucial method for addressing complex TMJ structural issues.

Implications:

• Corrective surgical intervention can significantly improve outcomes for patients with TMJ disorders and associated dentofacial deformities.
• The combined surgical approach offers predictable and successful treatment for complex TMJ and jaw alignment issues.
• This paper provides valuable insights for clinicians managing TMJ pathologies and planning surgical corrections.
