Tips for Treating Trigger Points - Lateral Pterygoid

 

Trigger Points in the Lateral Pterygoid are a Common Cause of Cheek Pain 

The superior head of the lateral pterygoid is sometimes called the sphenomeniscus, because it inserts into the disc of the temporomandibular joint.

ORIGIN

Superior head: lateral surface of greater wing of sphenoid.
Inferior head: lateral surface of lateral pterygoid plate of sphenoid.

BITE PLATES/BLOCKS/ OCCLUSAL SPLINTS
Opinion varies as to efficacy, type, and duration of use for occlusal devices. An evidence base suggests they can be beneficial.

POSTURE

Head forward or upper crossover patterns can be treated by a range of manual and trigger point therapists.

ADVICE

Chew on both sides of mouth. Avoid gum chewing/nail biting. Bite guard, phone-in-neck postures.

SELF-HELP TECHNIQUE

1. Use pincer-grip pressure techniques inside of the mouth in the sulcus, right at the back of the molars (or wisdom teeth if you have them); push inward and upward toward the top of the cheek.

2. Apply gentle and gradually increasing pressure to the trigger point, while lengthening the affected/host muscle until you hit a palpable barrier. This should be experienced as discomfort and not as pain.

3. Apply sustained pressure until you feel the trigger point soften. This can take from a few seconds to several minutes. Repeat, increasing the pressure on the trigger point until you meet the next barrier, and so on.

To achieve a better result, you can try to change the direction of pressure during these repetitions.
