ABSTRACT
Objective:To observe the difference in the effect of simple titanium plate internal fixation and titanium plate internal fixation combined with titanium nail intermaxillary traction in the treatment of jaw fractures and their impact on the oral and maxillofacial function of patients.Methods:From August 2016 to May 2021, 94 patients with jaw fractures admitted to the Department of Stomatology, Linyi Central Hospital, Shandong (supplementing the gender, age range and average age of the patients), were divided into 47 cases in the control group, and the titanium plates were used alone, combined operation group 47 cases, titanium plate internal fixation combined with intermaxillary traction with titanium nails. The changes of oral and maxillofacial function and fracture healing were measured before operation and 3 months after operation, and the perioperative indicators and postoperative complications were recorded.Results:Three months after operation, the scores of maxillofacial function, mouth function and masticatory function in the combined operation group (0.52±0.09 points, 0.67±0.12 points, 0.58±0.08 points) were significantly lower than those in the control group (1.05±0.21 points, 1.14±0.22 points, 1.02±0.21 points) ( t=15.90, 12.86, 13.42, P<0.05). The effective rate of the combined operation group was 95.74% (45/47), which was significantly higher than that of the control group (80.85%, 38/47) (χ 2=5.05, P<0.05); there was no significant difference in operation time and hospitalization time between the groups ( P>0.05), the fracture healing time in the combined surgery group (65.02±7.06) d was significantly shorter than that in the control group (82.69±10.25) d ( t=9.73, P<0.05). The postoperative complication rate of combined treatment group was 6.38% (3/47), which was significantly lower than the control group 21.28% (10/47) (χ 2=4.37, P<0.05). Conclusions:In the treatment of jaw fractures, titanium plate internal fixation combined with titanium nail intermaxillary traction treatment can significantly improve the oral and maxillofacial function of patients, promote postoperative fracture healing, improve curative effect and reduce the incidence of complications compared with simple titanium plate internal fixation.
