Abstract:
Objective:To analyze the clinical effect of navigation-assisted cosmetic incision for reduction and internal fixation in treating unilateral B-type zygomatic fracture.Methods:A retrospective cohort study was performed on clinical data of 35 patients with unilateral type B zygomatic fracture treated from January 2018 to December 2019 in First Affiliated Hospital of Fujian Medical University. There were 20 males and 15 females at age range of 5-62 years [(38.7±11.3)years]. Navigation-assisted cosmetic incision for reduction and internal fixation was performed for 17 patients (navigation group), and empirical incision to reduction and internal fixation was performed for 18 patients (convention group). The length of bony zygomatic process (zygomatic process) and width of zygomatic temporal point (frontal width) of the bilateral zygomatic bone were measured on the horizontal axis of CT at 1 week after operation. The absolute values of the difference of bony zygomatic process degree and frontal bony width between affected side and the healthy side were compared between the two groups. The patients′ satisfaction and occurrence of complications such as lower eyelid ectropion, incision infection and facial nerve injury were compared between the two groups at half a year after operation.Results:All patients were followed up for 6-24 months [(9.3±1.2)months]. The absolute difference of bony zygomatic process was 0.60(0.25, 0.85) mm in navigation group, and was 0.75 (0.20, 1.98)mm in convention group ( P>0.05). The absolute difference of frontal bony width was (0.37±0.11)mm in navigation group, and was (2.47±0.63)mm in convention group ( P<0.01). Satisfaction rates by both objective evaluation and subjective evaluation in navigation group were better than that in convention group at half a year after operation (both P<0.05). Navigation group showed lower eyelid ectropion in 1 patient and incision infection in 1 patient. Convention group showed facial nerve injury in 1 patient and incision infection in 2 patients. There was no significant difference in the incidence of complications between navigation group [12%(2/17)] and conventional group [17%(3/18)] ( P>0.05). Conclusion:For unilateral type B zygomatic fracture, navigation-assisted cosmetic incision for reduction and internal fixation can more accurately restore the frontal width, and improve satisfaction rate as compared with empirical reduction and internal fixation.
