Arthrocentesis and arthroscopy are both minimally invasive surgical procedures used to treat temporomandibular joint (TMJ) disorders, but they differ in technique and application:

1. Arthrocentesis:

• Procedure: Involves the insertion of two needles into the TMJ space. One needle is used to inject a sterile solution (usually saline) to lavage or wash out the joint, while the other needle is used to remove the solution along with any inflammatory byproducts or debris.

• Indications: Typically used for patients with less severe TMJ dysfunction, particularly when there is joint pain, inflammation, or limited movement, often associated with disc displacement without reduction.

• Advantages: It is less invasive, usually performed under local anesthesia, with a quick recovery time. It is often effective for managing pain and improving mobility, especially in cases of acute or early-stage disorders.

• Limitations: It doesn’t allow for direct visualization of the joint structures, so it’s more of a therapeutic lavage than a diagnostic tool.

2. Arthroscopy:

• Procedure: Involves inserting a small camera (arthroscope) into the joint space through a small incision, which allows the surgeon to directly visualize the joint and perform more complex procedures if needed, such as removing adhesions, smoothing the joint surfaces, or repositioning the disc.

• Indications: Recommended for patients with more severe or persistent TMJ disorders, including chronic disc displacement, adhesions, or degenerative joint diseases. It’s both diagnostic and therapeutic since the surgeon can directly assess the joint’s condition and address specific issues.

• Advantages: Allows direct visualization of the joint structures and can be used for a broader range of interventions beyond lavage.

• Limitations: It is slightly more invasive than arthrocentesis, usually performed under general anesthesia, and may have a longer recovery time.
