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.
ABSTRACT
Objective: To evaluate the effectiveness of a new type of sutured titanium wire combined with titanium nail internal fixation in correction of serious old medial canthus deformity. Methods: Between March 2012 and June 2015, 18 patients with unilateral serious old medial canthus deformity were treated. There were 14 males and 4 females. The patient's age ranged from 23 to 62 years (mean, 42 years). The causes of deformity included accident injury in 10 cases, boxing injury in 4 cases, sharp device scratching in 3 cases, and animal bite in 1 case. All patients had been treated with suture or steel wire fixation in other hospitals to correct the medial canthus deformity and the deformity recurred. The interval between this operation and the first operation was 6 months to 2 years (mean, 16 months). The nasal root or medial canthus skin scar incision was used as the operative approach, and the adhesion of the medial canthus ligament to the adjacent tissues was fully loosened, then the tail end of the new type sutured titanium wire was fixed to the residual end of the medial canthus ligament. After passing through the scar tissue, the needle end of wire was fixed on the titanium nail in the bone wall of anterior lacrimal crest. The position and shape of the medial canthus angle was determined by adjusting the tightness of titanium wire. Results: All incisions healed by first intention. All patients were followed up 6-12 months (mean, 10 months). In 16 cases, the medial canthus deformity was obviously corrected, and the appearances of bilateral eyes were basically symmetrical, without exposure of titanium nail and titanium wire. The medial canthus was retreated at 2 mm after 6 months in 2 cases, who were satisfied with their appearance without reoperation. Conclusion: Application of the new type of suture titanium wire combined with titanium nail in the correction of serious old medial canthus deformity can achieve good effectiveness with the low recurrence rate.
