Botox for Jaw Tightness After Head and Neck Radiation
Part of Brain & nervous system, Cancer clinical trials.
This study tests whether Botox injections into the jaw muscles can help head and neck cancer survivors who have trouble opening their mouths (trismus) after radiation therapy. If you have tight or painful jaw muscles and limited mouth opening, this treatment may offer relief.
Summary written for real people, not researchers, by Clin2.

This study tests whether manual therapy (hands-on treatment) can improve mouth opening, swallowing, and movement in people who had head and neck cancer surgery or radiation. It may help if you have jaw stiffness, pain, or shoulder problems after treatment.
This study tests whether a program of early monitoring and physical therapy can help prevent or reduce jaw stiffness (trismus) after radiation therapy for head and neck cancer. It is for patients who are about to start radiation and want to keep their jaw working well.
This trial tests whether injecting botulinum toxin (Botox) before radiation therapy can help protect your salivary glands and reduce dry mouth, a common side effect of radiation for head and neck cancer. If you're newly diagnosed with advanced head and neck cancer and are about to start radiation, this could be an option to explore.
