4. Diagnosis

Lockjaw is typically simple to diagnose because of its incredibly visible symptoms. Doctors will measure the distance the patient can open their mouth. A physical exam may also include palpating for muscle tension or stiffness. Imaging techniques such as x-rays, ultrasounds, MRIs, and CT scans can identify any physical issues around the jaw. In cases where cancer is a possible cause, a biopsy may be necessary.
