Trismus in head and neck cancer patients in Sweden: incidence and risk factors.

Abstract

This study reports a high incidence of trismus in H&N cancer patients after treatment. Furthermore, it was found that poor physical function before the start of treatment and high external beam radiation therapy (EBRT) dosages (>50 Gy) were related to significantly more trismus. Future prospective studies are needed to provide a better understanding of different risk factors associated with trismus development, the impact on health-related quality of life, and the effects of early treatment.
