Effect of rigid internal fixation combined with traction reduction fixation on the recovery of maxillofacial anatomy and oral function in patients with traumatic fractures in the oral and maxillofacial region
Objective To analyze the effect of rigid internal fixation combined with traction reduction fixation on the recovery of maxillofacial anatomy and oral function in patients with traumatic fractures in the oral and maxillofacial region.Methods 74 patients with traumatic fractures in the oral and maxillofacial region were randomly divided into a control group and an observation group with the ratio of 1:1,with 37 cases in each group.The control group was treated with rigid internal fixation,and the observation group was treated with rigid internal fixation combined with traction reduction fixation.The recovery of maxillofacial anatomy and oral function were compared between the two groups.Results The oral function recovery rate,appearance recovery satisfaction,and maxillofacial anatomy recovery of the observation group were 91.89%,97.30%,and 100.00%,which were higher than 72.97%,75.68%,and 78.38%of the control group,and the difference was significant in comparison(P＜0.05).After surgery,the maxillofacial function score,the total occlusal contact area and the total maximum strength of the occlusal point of the patients in both groups improved compared with those before surgery in this group,the occlusal asymmetry index decreased compared with that before surgery in this group,and the occlusal contact time shortened compared with that before surgery in this group;in the observation group,the maxillofacial function score was(17.44±0.34)points,the total occlusal contact area was(321.44±58.41)mm2,and the total maximum strength of the occlusal point was(31.44±3.84)kg,which were higher than(15.98±0.23)points,(264.42±48.97)mm2,and(27.13±2.46)kg in the control group;the observation group had lower occlusal asymmetry index of(20.48±2.33)%than(24.36±4.12)%in the control group;the observation group had shorter occlusal contact time of(1.45±0.21)s than(1.89±0.46)s in the control group(P＜0.05).Conclusion For patients with traumatic fractures in the oral and maxillofacial region,adding traction reduction fixation on the basis of rigid internal fixation can promote the recovery of oral function and oral maxillofacial anatomy of patients,and it is worth promoting.
