OBJECTIVES/HYPOTHESIS: Most otoplasty techniques are variations of suturing and sculpting concepts. Thick cartilage and its tricky everlasting reshaping is a difficult task in suture techniques. It is more difficult to predict and control the final result in cartilage sculpting techniques. Animal studies demonstrated temperature-dependent cartilage stress relaxation during laser application resulting in stable shape changes. The aim of this study was to describe a novel surgical technique of carbon dioxide laser-assisted cartilage reshaping (CO(2) LACR) otoplasty and to show its outcome.
Prospective case series study.
Sixteen patients with 32 prominent ears were involved prospectively. Carbon dioxide laser evaporation of the perichondrium and partial thickness of the medial surface of auricular cartilage and a pair of parallel laser incisions on scaphal and conchal lines were performed. The cartilage was fixed with absorbable Vicryl mattress sutures. Demographics, early and late postoperative outcomes, patients/parents and doctors satisfaction in the follow-up were studied.
A total of 32 ears underwent repair. Patients ages ranged from 4 to 7 years (mean, 5.5 years). Average follow-up was 2.4 years. No cases required revision surgery. In late assessment 14 patients were pleased, two were satisfied, and no patients were unsatisfied. All patients had four to six of the six criteria for surgical success as defined by the study without complications.
The present technique of CO(2) LACR otoplasty resulted in endurance of auricular appearance and symmetry, with good to satisfactory outcome to patient/parent.
目的/假设:大多数耳成形术技术是缝合和塑形概念的变体。厚软骨及其棘手的永久重塑是缝合技术中的一项艰巨任务。在软骨雕刻技术中,更难预测和控制最终结果。动物研究表明,激光应用过程中软骨的温度依赖性应力松弛导致稳定的形状变化。本研究旨在描述一种新型的二氧化碳激光辅助软骨重塑(CO 2 LACR)耳成形术的手术技术,并展示其结果。
前瞻性病例系列研究。
前瞻性纳入 16 例 32 只外耳突出的患者。对软骨的软骨膜和内侧表面的部分厚度进行二氧化碳激光蒸发,并在肩胛和耳甲线上进行一对平行的激光切口。软骨用可吸收的 Vicryl 褥式缝线固定。研究了患者的人口统计学资料、早期和晚期术后结果、患者/家长和医生在随访中的满意度。
共修复 32 只耳朵。患者年龄为 4 至 7 岁(平均 5.5 岁)。平均随访时间为 2.4 年。无病例需要再次手术。在晚期评估中,14 例患者满意,2 例患者满意,无患者不满意。所有患者均符合研究定义的 6 项手术成功标准中的 4 至 6 项,且无并发症。
CO 2 LACR 耳成形术的目前技术可持久保持耳部外观和对称性,且患者/家长的结果良好至满意。
