The use of a 2.0-mm locking plate system was evaluated in mandibular surgery.
53 patients (42 male, 11 female) with a total of 56 mandibular fractures were treated with a 2.0-mm mini-locking-plate system and retrospectively examined. Gender, age, cause of fracture, surgical access, classification of fractures, osteosynthesis, postsurgical findings and complications were evaluated.
Assault in male patients (mean age 31) was the most common aetiological factor. Fractures in women (mean age 43 years) mostly occurred due to falls. Mandibular angle fractures were the most common and this anatomical site also presented the highest complication rate. Only 6% of patients had minor occlusal disturbance postoperatively, and minor complications (infections and dehiscence) occurred in 14% of patients in this study. Major complications only occurred in one patient included in the study (1.9%). Risk factors for the development of complications in this series were a history of alcohol or tobacco use, mandibular angle fractures, associated facial fractures, presurgical occlusal disturbance and concomitant dental infections. Surgical access to the fracture and the interval from injury to surgery was not associated with the development of complications.
The use of a 2.0-mm locking plate system with its advantages of improved handling characteristics, increased stability, shorter surgical time and the preservation of bony perfusion is a viable alternative to conventional miniplates in the management of mandibular fractures.
评估 2.0mm 锁定板系统在下颌骨手术中的应用。
对 53 例（42 例男性，11 例女性）共 56 例下颌骨骨折患者采用 2.0mm 微型锁定板系统进行治疗，并进行回顾性检查。评估性别、年龄、骨折原因、手术入路、骨折分类、骨愈合、术后发现和并发症。
男性患者（平均年龄 31 岁）中最常见的病因是意外伤害。女性（平均年龄 43 岁）骨折大多是由于跌倒引起的。下颌角骨折最为常见，该解剖部位的并发症发生率也最高。仅有 6%的患者术后存在轻微咬合紊乱，本研究中 14%的患者出现轻微并发症（感染和裂开）。仅 1 例（1.9%）患者发生严重并发症。本系列并发症发生的危险因素包括有饮酒或吸烟史、下颌角骨折、合并面部骨折、术前咬合紊乱和伴发牙感染。骨折的手术入路和受伤至手术的时间间隔与并发症的发生无关。
使用 2.0mm 锁定板系统具有操作特点改善、稳定性增加、手术时间缩短和骨血供保护等优点，是传统微型板治疗下颌骨骨折的可行替代方法。
