Imaging Approach to Temporomandibular Joint Disorders

Area of Science:

• Radiology
• Orthopedics
• Anatomy

Background:

• Internal derangement is the most frequent temporomandibular joint (TMJ) disorder.
• Other common TMJ pathologies include osteoarthritis and trauma.
• Less common conditions encompass rheumatoid arthritis, tumors, infection, and osteonecrosis.

Purpose of the Study:

• To present a systematic approach for interpreting TMJ pathologies.
• To correlate anatomical structures with imaging findings.
• To highlight clinical and therapeutic aspects of TMJ diseases.

Main Methods:

• Systematic interpretation based on major anatomical structures: disc-attachments, joint space, condyle, and lateral pterygoid muscle.
• Discussion of relevant graphic anatomy.
• Review of state-of-the-art imaging techniques.

Main Results:

• Internal derangement is the most common TMJ disorder.
• Osteoarthritis and trauma are the next most frequent pathologies.
• A structured approach aids in understanding diverse TMJ conditions.

Conclusions:

• A systematic approach, integrating anatomy and advanced imaging, is crucial for diagnosing TMJ disorders.
• Understanding the frequency and characteristics of various TMJ pathologies is essential for effective management.
• This framework facilitates the interpretation of complex TMJ conditions.
