Abstract: PURPOSE: To explore the practical effect of quality control circle (QCC) movement on improving the compliance of postoperative functional exercise in patients undergoing temporomandibular joint(TMJ) anchorage surgery. METHODS: A convenience sampling method was used to select 50 cases with temporomandibular joint diseases (TMD) diagnosed in the Department of Oral Surgery as the control group from July 2019 to August 2019, and 50 cases were selected as the experimental group using the same method from December 2019 to January 2020. Patients in the control group were given routing nursing care. QCC program with the theme of "Improving postoperative functional exercise compliance of patients with temporomandibular disorder" was conducted in the experimental group, in which common quality control tools were used to analyze the causes and made strategies for those with low functional exercise compliance. The functional exercise compliance, pain score and maximum mouth opening were compared between the two groups. SPSS 20.0 software package was used for statistical analysis. RESULTS: The functional exercise compliance of TMD patients increased from 57.90% to 87.78%, maximum mouth opening at postoperative 1 month increased from (26.54±5.33)mm to (28.32±4.67)mm(P<0.05), while VAS score of pain decreased from 2.48±1.084 to 1.40±0.957(P<0.05). CONCLUSIONS: Implementation of QCC program has positive effect on improving the postoperative functional exercise compliance and the joint function recovery of TMD patients, promoting the comprehensive ability of nurses and assuring the nursing quality.
