Abstract
Introduction: Myofascial pain cause significant functional
limitations and muscle stiffness, particularly affecting the masseter
muscles. Ultrasound is a reliable and
non-invasive method for evaluating the masticatory muscles. The newly developed
shear wave elastography method also provides information about the stiffness of
the tissue.
Aim: This study investigates the relationship
between masseter muscle elasticity and jaw functional limitations in patients
with myofascial pain.
Material and Methods: A cross-sectional study was conducted on 25
patients with myofascial pain. B-mode ultrasonography and shear wave
elastography were used to assess the thickness and elasticity of the bilateral
masseter muscles both at rest and during clench. Jaw function was measured
using the Jaw Functional Limitation Scale-8, along with assessments of pain
intensity and maximum mouth opening.
Results: Our study revealed that masseter muscle stiffness and pain
intensity increased and maximum mouth opening decreased in patients with
myofascial pain. In the Jaw Functional Limitation Scale-8, chewing tough foods
and yawning became more restricted as masseter muscle stiffness increased, with
both showing statistically significant p-values (p < 0.05). It was also
found that chewing tough foods was significantly associated with maximum mouth
opening (p < 0.05). According to the total score, the most limited function
was chewing hard foods (61.2%), while the least limited function was swallowing
(11.6%).
Conclusions: Shear wave elastography is an effective method
for assessing muscle stiffness in patients with myofascial pain. A significant
relationship has been found between muscle elasticity and functional
limitations.
