Abstract: PURPOSE: To develop a new type of oral and maxillofacial local compression band and evaluate its effectiveness in oral and maxillofacial surgery. METHODS: A total of 72 patients undergoing alveolar surgery in Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine were randomly divided into control group and experimental group, with 36 patients in each group. The control group was subjected to postoperative local compression with conventional bandage, while the experimental group was subjected to a new type of oral and maxillofacial local compression band. Both groups were operated by the same physician. The compression band was removed on the second day after surgery, and the swelling, bleeding and healing of the wound were observed, and the comfort of the patients and the satisfaction of the attending physicians were scored. SPSS 20.0 software package was used for data analysis. RESULTS: There was no significant difference in general data such as gender, age and surgery between the two groups of patients. The incidence of facial swelling in the experimental group was 5.6%(2/36), significantly lower than 33.3%(12/36) in the control group (P< 0.05); the incidence of bleeding in the experimental group was 2.8% (1/36), significantly lower than 16.7% (6/36) in the control group (P< 0.05). The postoperative mouth opening degree and skin compression comfort of the patients in the experimental group were significantly better than those in the control group(P< 0.05); the satisfaction of the attending physicians in the experimental group in terms of operation convenience, time-saving and labor-saving, and treatment effect was significantly better than that in the control group (P< 0.05). CONCLUSIONS: The new type of oral and maxillofacial local compression band is simple and easy to use. It can reduce the incidence of maxillofacial swelling and bleeding, and is beneficial for wound healing, thus is worthy of promoting.
