Correction of prominent ears is a common plastic surgical procedure. We introduced a new non-invasive laser-assisted cartilage reshaping (LACR) technique as an alternative to invasive surgical otoplasty.
Since our first report in 2006, 32 LACR procedures in 17 patients have been performed at the Antoni De Gimbernat Foundation in collaboration with the French National Institute of Health and Medical Research (INSERM) U703. For 15 patients, the procedure was bilateral, for the remaining 2 patients LACR was performed only on one side. The treatment consisted of seven stacked pulses (3 ms, 2 Hz, 84 J/cm(2) cumulative fluence) applied using a 4-mm spot hand piece. Early and late complications were defined and reviewed for the whole series. Satisfaction was assessed by the patients using a visual analogue scale from 0 (unsatisfied) to 10 (highly satisfied). The superior and middle cephaloauricular distances were prospectively evaluated.
Except for two cases of dermatitis, there were no early complications and no late complications (like keloids) in the series. The mean superior and middle cephaloauricular distances were, respectively, 12.3 ± 1.9 and 13.7 ± 1.6 mm compared to 17.8 ± 3.1 mm (p < 0.01) and 23.9 ± 1.9 mm (p < 0.01) before operation. Mean patient satisfaction was 8.6/10 with all patients reporting that they would be willing to undergo the procedure again, if required.
LACR appears to be a safe and reproducible method for the treatment of protruding ears. Other applications of this technique, like laser assisted septal cartilage reshaping (LASCR) for septum deviation, have been recently described.
招风耳矫正术是一种常见的整形手术。我们引入了一种新的非侵入性激光辅助软骨重塑（LACR）技术，作为侵入性手术耳成形术的替代方法。
自2006年首次报告以来，在安东尼·德·金贝纳特基金会与法国国家健康与医学研究院（INSERM）U703合作下，已对17例患者进行了32次LACR手术。其中15例患者接受双侧手术，其余2例患者仅进行单侧LACR手术。治疗采用4毫米光斑手持探头施加七个叠加脉冲（3毫秒，2赫兹，84焦耳/平方厘米累积能量密度）。对整个系列定义并回顾了早期和晚期并发症。患者使用0（不满意）至10（非常满意）的视觉模拟量表评估满意度。前瞻性评估了上半和中耳头耳距离。
该系列中除2例皮炎外，无早期并发症，也无晚期并发症（如瘢痕疙瘩）。术前上半和中耳头耳平均距离分别为17.8±3.1毫米（p<0.01）和23.9±1.9毫米（p<0.01），术后分别为12.3±1.9毫米和13.7±1.6毫米。患者平均满意度为8.6/10，所有患者均表示如有需要，愿意再次接受该手术。
LACR似乎是一种安全且可重复的治疗招风耳的方法。最近还描述了该技术的其他应用，如用于鼻中隔偏曲的激光辅助鼻中隔软骨重塑（LASCR）。
