目的: 研究低水平激光治疗(LLLT)对创伤后面神经损伤的临床疗效。方法: 选择2020年1月至2022年6月收治的创伤后面神经损伤患者45例,按照治疗方法不同分为3组。观察组采用LLLT面神经分布区域照射治疗,阳性对照组采用传统高压氧治疗,阴性对照组为后续未参加相关治疗的患者。比较3组治疗前后Sunnybrook面神经评分表系统(Sunnybrook facial grading system,SBGS)及面肌肌电图检测结果。结果: 与治疗前相比,观察组SBGS评分提高,面部肌肉运动潜伏期明显缩短,动作电位的波幅明显提高,治疗效果优于阳性和阴性对照组(P＜0.05);而阴性对照组患者随访期间SBGS评分及面神经肌电图检测结果变化不明显(P＞0.05)。结论: 应用LLLT有利于创伤后早期面神经损伤患者神经功能康复,操作方便,安全性高,可在医院推广应用。
Objective: To study the clinical effect of low level laser therapy (LLLT) on facial nerve injury after trauma. Methods: Forty-five patients with facial nerve injury after trauma admitted from January 2020 to June 2022 were selected and divided into three groups according to different treatment methods. The observation group was treated with LLLT facial nerve distribution area irradiation, the positive control group was treated with traditional hyperbaric oxygen therapy, and the negative control group was the patients who did not participate in the follow-up treatment. The results of Sunnybrook facial grading system (SBGS) and facial electromyography were compared among the three groups before and after treatment. Results: Compared with before treatment, the SBGS score of the observation group was improved, the latency of facial muscle movement was significantly shortened, and the amplitude of action potential was significantly improved, the therapeutic effect was better than that of the positive and negative control groups (P＜0.05). However, there was no significant change in SBGS score and facial nerve electromyography in the negative control group during the follow-up period (P＞0.05). Conclusion: The application of LLLT is beneficial to the recovery of neurological function in patients with early facial nerve injury after trauma, and it is easy to operate, with high safety. It can be popularized and applied in hospitals.
