微型钛板内固定在口腔颌面骨折效果中的应用价值

〔摘 要〕 目的：分析微型钛板内固定在口腔颌面骨折治疗中的应用价值。 方法：选取 2020 年 4 月至 2021 年 7 月于河南科技大学第一附属医院（开元院区）就诊的口腔颌面骨折患者 80 例，按照随机分组的方法将其分为微型钛板组和不锈钢板组，每组各 40 例。微型钛板组采用微型钛板内固定法进行治疗，不锈钢板组采用不锈钢板固定法进行治疗。比较两组患者口面部肌功能、骨折愈合情况、并发症发生情况。 结果：手术后，两组患者唇姿势评分比较，差异无统计学意义（P ＞ 0.05），微型钛板组患者外观与姿势其余项目评分、运动评分高于不锈钢板组，差异具有统计学意义（P ＜ 0.05）。微型钛板组患者张口度高于不锈钢板组，差异具有统计学意义（P ＜ 0.05）。两组患者咬合正常率比较，差异无统计学意义（P ＞ 0.05）。微型钛板组患者并发症发生率低于不锈钢板组，差异具有统计学意义（P ＜ 0.05）。 结论：微型钛板内固定与不锈钢板固定对咬合度均具有较好的临床效果，但微型钛板内固定能更有效地促进患者口面部肌功能的恢复，加快颌面骨折愈合速度，降低并发症发生率，利于患者术后恢复。

Application Value Analysis of Micro Titanium Plate Internal Fixation in Oral and Maxillofacial Fracture

〔Abstract〕　Objective To investigate the application value of micro titanium plate internal fixation in the treatment of oral and maxillofacial fracture. Methods A total of 80 patients with oral and maxillofacial fracture who were admitted to the First Affiliated Hospital of Henan University of Science and Technology (Kaiyuan District) from April 2020 to July 2021 were selected and divided into micro titanium plate group and stainless steel plate group according to random group method, with 40 cases in each group. The micro titanium plate group was treated with the micro titanium plate internal fixation method, and the stainless steel plate group was treated with the stainless steel plate fixation method. Oral and facial muscle function, fracture healing and the incidence of complications were compared between the two groups. Results After operation, there was no significant difference in lip posture scores between the two groups (P > 0.05) . The other objects of appearance and posture scores and exercise scores in the micro titanium plate group were higher than those in the stainless steel plate group, and the differences were statistically significant (P < 0.05). The mouth opening of patients in the micro titanium plate group was higher than that in the stainless steel plate group, and the difference was statistically significant (P < 0.05). There was no significant difference in occlusal degree between the two groups (P > 0.05). The incidence of complications in the micro titanium plate group was lower than that in the stainless steel plate group, and the difference was statistically significant (P < 0.05). Conclusion Micro titanium plate internal fixation and stainless steel plate fixation both have good clinical effects on occlusal degree, but micro titanium plate internal fixation can more effectively promote the recovery of oral and facial muscle function, accelerate the healing speed of maxillofacial fracture, reduce the incidence of complications, and facilitate postoperative recovery of patients.
