New Research Correlates Radiation Dose to the Masseter and Pterygoid Muscles with the Development of Trismus (Article Review)

Posted by Sarah Schuman, MS, CCC-SLP on 5/21/2019 to Head & Neck Cancer, Radiation Therapy

Reconfirmed!! New research reinforces the correlation between radiation dose to the masseter and pterygoid muscles with the development of trismus.


The study “Radiation dose to the masseter and medial pterygoid muscle in relation to trismus after chemoradiotherapy for advanced head and neck cancer” stresses the impact of radiation dose on the ipsilateral masseter muscle and the ipsilateral medial pterygoid muscle in head and neck cancer patients. A meaningful analysis of data was conducted across 83 patients treated for advanced squamous cell carcinoma of the head and neck. These patients participated in a preventive exercise program for mouth opening and MIO measurements were compared. The study concluded that radiation dose on the ipsilateral masseter muscle and ipsilateral medial pterygoid muscle is predictive for trismus.
