PEMF (pulsed electromagnetic fields) founds application in several medical fields to accelerate bone wounds healing and to reduce inflammation. The aim of our study was to evaluate the effectiveness of PEMF in reducing postoperative swelling and pain in patients undergoing orthognathic surgery.
A prospective observational monocentric study was conducted on a sample of 30 patients undergone to orthognathic surgery in Maxillofacial Surgery Unit of University of Naples Federico II. The patients who followed these inclusion criteria were enrolled in the study: age ≥ 18 years, Class III malocclusion, Surgical procedure of Le Fort I osteotomy + Bilateral Sagittal Split Osteotomy (BSSO), Written informed consent. Patients were divided into two groups: Group SD) postoperative standard treatment with medical therapy and cryotherapy, Group SD + PEMF) postoperative standard therapy + PEMF. Each patient underwent a 3D facial scan, at one (1d) and four (4d) days after surgery to compare the swelling reduction. The pain score was assessed through VAS score and analgesics administration amount.
In SD + PEMF group, the facial volume reduction between 1d and 4d scan was on average 56.2 ml (6.23%), while in SD group, it was 23.6 ml (2.63%). The difference between the two groups was 3.6% (p = 0.0168). VAS pain values were significantly higher in SD group compared to SD + PEMF group in the second day after surgery (P = 0.021) and in the total 4 days (P = 0.008).
Our data suggest that PEMF is valid tool to promote faster postoperative swelling and pain reduction in patients undergoing orthognathic surgery.
脉冲电磁场（PEMF）在多个医学领域得到应用，以加速骨创伤愈合和减轻炎症。我们的研究旨在评估 PEMF 在减少正颌手术患者术后肿胀和疼痛方面的有效性。
对那不勒斯费德里克二世大学颌面外科单元接受正颌手术的 30 名患者进行了一项前瞻性观察性单中心研究。符合以下纳入标准的患者被纳入研究：年龄≥18 岁，III 类错牙合，Le Fort I 截骨术+双侧矢状劈开截骨术（BSSO）手术，书面知情同意。患者分为两组：标准治疗组（SD 组），术后接受药物治疗和冷敷；标准治疗+PEMF 组（SD+PEMF 组），术后接受标准治疗+PEMF。每位患者均在术后第 1 天（1d）和第 4 天（4d）进行 3D 面部扫描，以比较肿胀减轻情况。通过 VAS 评分和镇痛药用量评估疼痛评分。
在 SD+PEMF 组中，从第 1 天到第 4 天的面部体积减少量平均为 56.2ml（6.23%），而在 SD 组中，减少量为 23.6ml（2.63%）。两组之间的差异为 3.6%（p=0.0168）。与 SD+PEMF 组相比，SD 组术后第 2 天（P=0.021）和总 4 天（P=0.008）的 VAS 疼痛值明显更高。
我们的数据表明，PEMF 是一种有效的工具，可促进接受正颌手术患者更快地减轻术后肿胀和疼痛。
