Research progress on posttreatment trismus in malignant head and neck tumors

Malignant tumors in the head and neck seriously threaten the physical and mental health of patients.After treatment,they may cause many complications,such as facial deformity,difficulties with chewing,dysphagia and asaphia.Among them,trismus(restricted mouth opening)is one of the most common complications after treatment of malignant oral-maxillofacial tumors.In severe cases,patients may even suffer from trismus and eating difficulties,finally leading to malnutrition and even cachexia.Therefore,it not only affects the quality of life of patients and even endangers their lives but also brings heavy social and economic burdens.How to effectively prevent and treat posttreatment trismus is a clinical problem that is easily ignored by head and neck surgeons and urgently needs to be solved.The results of a literature review showed that trismus may be related to the tumor clinical stage,tumor site,treatment used,radiotherapy site,radiotherapy dose,radiotherapy type,and other factors.The incidence of trismus tends to be significant 6 months after treatment.Without early intervention,the resulting dysfunction may become more severe.Current studies have shown that the prevention and treatment of restricted mouth opening is based on controlling the progress of restricted mouth opening and restoring function.Exercise intervention for trismus can significantly improve the restricted mouth opening of patients with malignant head and neck tumors after treatment.
