Objective: To summarize the current progress of laser-assisted cartilage reshaping (LACR) for prominent ear.
Methods: The domestic and abroad article concerning the LACR in treatment of prominent ear was reviewed and analyzed.
Results: As a new technique, there were three types of LACR therapies that been used for prominent ear. LACR with the 1 064 nm Nd/YAG laser is painful and the penetration depth of the 1 064 nm Nd/YAG laser is greater than that of the 1540 nm Er/Glass laser which is caused more tissue injury. LACR with the 1 540 nm Er/Glass laser has high absorption by the ear cartilage and produce less injury to the surrounding tissue. Use of the CO 2 laser permitted cartilage reshaping combined with both vaporization and incisions, which complicates the technique, although, with low recurrence rate and definite effect. Insisting on wearing ear mold is the key to get satisfactory effectiveness for postoperative patients. The complications of LACR for prominent ear, such as the dermatitis, perforation of the skin, hematoma, or infection, should be noticed.
Conclusion: Application of LACR for prominent ear just has a short period of time, limited number of cases, and few relevant literature reports. Its effectiveness needs to be further studied and clarified.
目的: 总结激光辅助软骨重塑形技术（laser-assisted cartilage reshaping，LACR）在临床矫正招风耳中的应用进展。.
方法: 查阅近年国内外有关 LACR 矫正招风耳的相关文献，并进行总结分析。.
结果: 作为一项临床新技术，目前 LACR 矫正招风耳方法主要有 3 种，其中 1 064 nm Nd/YAG 激光穿透性高，但组织损伤大，疼痛明显；1 540 nm Er/Glass 激光被耳廓软骨吸收率较高，对周围组织损伤小，不会造成明显疼痛；CO 2 激光联合外科手术矫正招风耳，疗效确切，复发率低，但过程繁琐。术后坚持佩戴耳模是获得满意疗效的关键。此外，LACR 矫正招风耳也存在皮炎、皮肤灼伤、穿孔、感染等并发症。.
结论: LACR 应用于临床矫正招风耳的时间较短、病例数有限，相关文献报道也较少，其确切效果有待进一步研究明确。.
