To explore the effect of microincision approach rigid internal fixation in patients with oral and maxillofacial fractures. Methods A total of 80 patients with oral and maxillofacial fractures admitted to Weihai Central Hospital Affiliated to Qingdao University from June 2021 to June 2022 were selected as the research objects. According to the random number table method, they were divided into control group (n =41) and study group (n =39). The control group was treated with intermaxillary ligation and fixation, and the study group was treated with microincision approach rigid internal fixation. The fracture healing rate, quality of life, incidence of adverse reactions and recovery satisfaction were compared between the two groups. Results The total healing rate of fracture in the study group was 94.87%, which was higher than 78.05% in the control group (P <0.05). The scores of quality of life in the study group were higher than those in the control group (P <0.05). The incidence of adverse reactions in the study group was 5.13%, which was lower than 24.39% in the control group (P <0.05). The recovery satisfaction of the study group was 97.44%, which was higher than 82.93% of the control group (P <0.05). Conclusion Microincision approach rigid internal fixation is effective in the treatment of oral and maxillofacial fractures, which can effectively improve the fracture healing rate and quality of life of patients, with fewer adverse reactions and higher overall satisfaction of patients. It is worthy of clinical application.
