【摘要】：目的:总结分析颌间牵引钉在颌骨骨折手术治疗中的使用方法、效果及注意事项。方法:在168例颌骨骨折内固定手术中,应用颌间牵引钉牵引骨折端复位,恢复并维持咬合关系稳定。记录颌间牵引钉使用数目、位置、牵引效果及术后并发症。结果:168例手术中共使用颌间牵引钉705枚,其中:使用4枚者147例(88%),6枚者12例(7%),5枚者9例(5%)。使用位置:5-4 4-55-4 4-5牙根间336枚(47.7%),4-3 3-44-3 3-4牙根间292枚(41.4%),6-5 5-66-5 5-6牙根间50枚(7.1%);其余部位27枚(3.8%)。术后92例咬合关系正常,无需牵引;76例咬合关系不协调或有偏差,经术后4~14 d牵引,71例咬合关系恢复正常,总有效率97%。主要并发症是牵引钉周围黏膜疼痛23例(13.7%),牙根损伤13例(1.8%)、牵引钉松动11例(1.6%)、牙脱位2例(0.3%)。结论:颌间牵引钉最常见和安全的植入位置在尖牙到第一磨牙的牙根之间,植入位点距牙龈缘5~8 mm;植入数目4~6枚可满足手术需要;颌间牵引钉弹性牵引有一定并发症,应注意防范。
[Abstract]:Objective: to summarize and analyze the application, effect and attention of intermaxillary traction nail in the surgical treatment of maxillary fracture. Methods: in 168 cases of internal fixation of jaw fracture, intermaxillary traction nail was used to reduce the fracture end. The number, location, traction effect and postoperative complications of intermaxillary traction nail were recorded. Results 705 intermaxillary traction nails were used in 168 cases of operation. Among them, there were 147 cases with 4 cases and 6 cases with 6 cases with 7 cases with 7 cases with 5 and 5 cases with 5 cases with 5 cases and 5 cases with 5 cases with 5: 44-55-4 5 teeth. 336 pieces between the roots of 5: 4 4 4 5 5 5 4 4 5 4 5 5 5 4 teeth with 47.77-3 47.74-3 44-3 3 44-3 with 292 pieces of 41.4 5 5 66-5 5 6 5 6 teeth between the roots of the two teeth were used, and the rest 27 pieces had 3.80.The occlusion relationship was normal in 92 cases after operation, and there was no significant difference between the two groups. The occlusal relationship of 76 cases without traction was not coordinated or deviated, and the occlusion relationship returned to normal in 71 cases after 4 days of traction 14 days after operation. The total effective rate was 97.The main complications were 23 cases of mucosal pain around the traction nail, 13 cases of root injury, 13 cases of root injury, 11 cases of loosening of the nail and 1.6% of the total effective rate, and 2 cases of dislocation. Conclusion: the most common and safe placement of the intermaxillary traction nail is between the canine and the root of the first molar. The implantation site was 5 ~ 8 mm from the gingival margin and the number of implant was 46. The intermaxillary traction nail elastic traction had some complications and should be taken precautions.
