Comparative study of different surgical approaches in the treatment of zygomatic complex fractures

Objective　To observe the effects of open reduction and internal fixation through local small incision and semi coronal incision in the operation of zygomatic complex fractures. Methods　A prospective study was conducted to select 93 patients with zygomatic complex fractures who were treated in the Department of Stomatology, The People's Hospital of Taierzhuang District, Zaozhuang from January 2017 to August 2021. The patients were divided into a transcranial semi-coronal incision group (45 cases) and a local small incision group (48 cases). The operation time and intraoperative bleeding volume were compared between the two groups. Three dimensional reconstruction of maxillofacial CT was performed again 3 months after operation to evaluate fracture reduction and healing, and the success rate of reduction was compared between the two groups. The incidence of adverse reactions such as alopecia and scalp sensory disturbance was compared. Independent sample t test was used for the measurement data and χ² test was used for the count data. Results　In the semi-coronal incision group, there were 33 males and 12 females, aged (36.24±7.58) years; in the small incision group, there were 37 males and 11 females, aged (34.81±6.73) years. The operation time and intraoperative bleeding volume of the semi-coronal incision group were (116.84±23.36) min and (86.73±20.47) ml, respectively, which were higher than those of the local small incision group (87.31±18.59) min and (25.06±12.53) ml], with statistically significant differences (both P<0.05). The success rate of reduction in the semi-coronal incision group was 97.78% (44/45), which was significantly higher than that in the small local incision group 83.33% (40/48)] (χ²=5.544, P=0.189); there was no statistically significant difference in the success rate of Zingg type B reduction between the two groups (P>0.05); the success rate of type C reduction in the semi-coronal incision group was 95.24% (20/21), which was higher than that in the local small incision group 70.00% (14/20)], with a statistically significant difference (χ²=4.609, P=0.032). The incidence of adverse reactions in the semi-coronal incision group was 24.44% (11/45), which was higher than that in local small incision group 6.25% (3/48)], with a statistically significant difference (χ²=6.012, P=0.014). Conclusions　Patients with Zingg classification type B can choose the local small incision approach to reduce the amount of bleeding and complications such as temporal depression and local alopecia. Type C patients can choose the semi coronal approach to achieve accurate reduction and reliable fixation.
