Trismus is a painful condition that can occur due to several causes such as: wisdom tooth removal, dental work, surgery in or around your mouth, and radiation therapy in head and neck cancer patients. It is a common topic of interest due to its vast causes and prevalence in the dental and medical community. Inflammation and contraction of the mastication muscles causes limited painful opening of the mouth and possible radiating pain to the ears and head. This condition can last from weeks to months. To date there is no set of curative treatment, however, there is ongoing research into prevention and treatment options, which can greatly vary according to the initial cause(s) of trismus in patients. The purpose of this paper serves to bring awareness to the medical and dental communities, individuals with trismus, and family members of those who suffer from this condition in the hopes that individuals can take the appropriate measures necessary to prepare and deal with this condition.
Key words: Trismus, restricted mouth opening, HRQL, radiation-therapy induced trismus
