Purpose: The Dynasplint Trismus System (DTS) can be used to treat trismus secondary to head and neck cancer. We conducted a prospective study with the following aims: (1) to determine the effects of DTS exercises on changes in mouth opening, pain, mandibular function, quality of life (QoL), and symptomatology and (2) to analyze the patients' perception on DTS exercises, including user satisfaction, experiences, comfort, and compliance.
Methods: The patients were instructed to exercise with the DTS for at least 16 weeks.
Objectives: Aims of this prospective cohort study were (1) to analyze the course of mouth opening up to 48months post-radiotherapy (RT), (2) to assess risk factors predicting decrease in mouth opening, and (3) to develop a multivariable prediction model for change in mouth opening in a large sample of patients irradiated for head and neck cancer.
Materials And Methods: Mouth opening was measured prior to RT (baseline) and at 6, 12, 18, 24, 36, and 48months post-RT. The primary outcome variable was mouth opening.
Purpose: The aim of this study was to evaluate the effect of TheraBite exercises on mouth opening and to analyze factors influencing this effect in a patient record evaluation.
Methods: Effect of exercises with a TheraBite to treat trismus was evaluated in 69 head and neck cancer patients of two university medical centers. Mouth opening was measured as interincisal distance in millimeters.
Purpose: This study aimed to assess: (1) oral symptoms of patients treated for oral or oropharyngeal cancer; (2) how patients rank the burden of oral symptoms; (3) the impact of the tumor, the treatment, and oral symptoms on functional outcome.
Methods: Eighty-nine patients treated for oral or oropharyngeal cancer were asked about their oral symptoms related to mouth opening, dental status, oral sensory function, tongue mobility, salivary function, and pain. They were asked to rank these oral symptoms according to the degree of burden experienced.
