摘要

鼻整形术，虽然有效的鼻部重塑，但经常导致术后水肿和延迟恢复。本随机对照试验评估了使用940 nm二极管激光器（4 J/cm²能量密度，0.1W功率，2.27 cm²光斑大小）光生物调节（PBM）治疗20例开鼻成形术后鼻肿胀的效果。参与者被分配到激光组（16个疗程，8周）或对照组，术前和术后1、4和8周进行标准化的鼻宽和鼻尖旋转摄影测量。与对照组相比，干预组鼻宽平均缩小2.5 mm (p=0.08)，鼻尖旋转改善3度（p=0.12），但未达到统计学意义。定性评估显示，70%的治疗患者水肿明显减轻，而对照组为30%。虽然受样本量的限制，这些发现表明940 nm PBM可能通过抗炎机制加速鼻整形术后肿胀的消退，值得在更大的队列中进一步研究。

Effects of photobiomodulation with 940 Nm diode laser on post-rhinoplasty nasal tip swelling: A randomized controlled trial

Rhinoplasty, while effective for nasal reshaping, frequently results in postoperative edema and delayed recovery.

This randomized controlled trial evaluated photobiomodulation (PBM) using a 940 nm diode laser (4 J/cm² energy density, 0.1 W power, 2.27 cm² spot size) for managing nasal swelling in 20 patients following open rhinoplasty. Participants were allocated to laser (16 sessions over 8 weeks) or control groups, with standardized photogrammetric measurements of nasal width and tip rotation preoperatively and at 1, 4, and 8 weeks postoperatively.

The intervention group demonstrated a mean nasal width reduction of 2.5 mm (p = 0.08) and a 3-degree improvement in tip rotation (p = 0.12) compared to controls, though statistical significance was not achieved. Qualitative assessments revealed marked edema reduction in 70 % of treated patients versus 30 % of controls.

While limited by sample size, these findings suggest 940 nm PBM may accelerate resolution of post-rhinoplasty swelling through anti-inflammatory mechanisms, warranting further investigation in larger cohorts.
