TRISMUS IN HEAD & NECK CANCER PATIENTS
80-90% of patients with radiation to the pterygoid and/or masseter muscles will develop trismus.
What is trismus? What causes trismus?
Trismus is defined as any restriction to mouth opening. Radiation treatment for head and neck cancer, surgery, trauma and TMJ disorders may all lead to the development of trismus.
How can you prevent and treat trismus?
Exercise therapy decreases both the incidence and severity of trismus. Jaw motion rehab systems like the OraStretch® press are most efficacious.
