Assessment of Concordance Between Chairside Ultrasonography and Digital Palpation in Detecting Myofascial Trigger Points in Masticatory Myofascial Pain Syndrome.

Ultrasonography and palpation concord moderately to substantially on the quantity of MTrPs and the involved muscle sections, but disagree on the location of the MTrPs within the muscle sections. Ultrasonography has the potentials as a chair-side diagnostic aid to help clinicians determine an accurate diagnosis, enhance patient experience during examination, and avoid unnecessary treatments that can mitigate the risk of iatrogenic damage.
