Methods: the project started in October 2020 and the project ended in January 2022. The data composition of the project were all confirmed patients in our hospital, with a total of 54 cases. The project was divided into the general group and the study group, with 27 cases in each group. The treatment parameters, changes in jaw height and width after surgery, treatment efficiency and surgical treatment indexes of the two groups were compared. Results: compared with other groups, the volume and area of cysts in the study group changed more significantly, and the bone mineral density of the patients increased more than that in the general group. Comparing the changes of jaw height and width, the parameters of the study group were higher than those of the conventional group. The number of patients in the study group who showed significant improvement in treatment was larger, and the total effective rate was significantly higher than that in the general group. Compared with the surgical treatment, although the treatment time and blood loss of the study group were more, the incidence of postoperative complications and recurrence rate were lower than those of the general group (P≤0.05). Conclusion: for the patients with odontogenic jaw cyst, the application of combined therapy is of positive significance in improving the disease pathological changes of the patients, improving the overall recovery quality, and reducing the influence of disease complications and recurrence rate.展开更多
