Objective To design a new type of mouth opener for mouth opening training in patients undergoing orthognathic surgery and evaluate its effectiveness. Methods 72 eligible orthognathic patients from September 2022 to August 2023 were selected as the study subjects and randomly divided into two groups using a random number table method: an experimental group of 36 cases and a control group of 36 cases. The experimental group received regular nursing methods and a new type of mouth opener for mouth opening training after orthognathic surgery, while the control group received regular nursing methods and a traditional duckbill mouth opener for mouth opening training. Compare the effects of the two groups. Results There was a significant difference in mouth opening between the experimental group and the control group at 1 and 3 months after surgery (P<0.05), and the experimental group was superior to the control group; There was no significant difference in the opening degree between the experimental group and the control group 6 months after surgery (P>0.05); There is a significant difference in comfort between the experimental group and the control group (P<0.05), and the experimental group is superior to the control group. Conclusion The new type of mouth opener not only measures the size of the mouth opening, is easy to use, and has high comfort, but also effectively improves the difficulty of opening the mouth for patients after orthognathic surgery. It is of great significance for early oral function recovery in patients after orthognathic surgery and has clinical value for promotion.
