研究目的:

旨在探讨二氧化碳点阵激光和微型环钻术用于治疗外科手术后线性瘢痕的临床疗效和安全性差异,通过平行对照研究方法,系统评估两种治疗方式在瘢痕改善、患者满意度及不良反应方面的表现,为颈部线性瘢痕的防治提供科学依据和临床指导。  

Objectives of Study:

aims to investigate the differences in clinical efficacy and safety between fractional carbon dioxide laser and mini-punch excision for the treatment of linear postoperative surgical scars. Using a parallel-controlled study design, it systematically evaluates the performance of both treatment modalities in terms of scar improvement, patient satisfaction, and adverse events, providing scientific evidence and clinical guidance for the prevention and management of linear neck scars.

组别:

激光组

样本量:

47

Group:

A

Sample size:

干预措施:

CO2点阵激光DeepFX模式治疗,治疗后外敷冷敷贴并予以常规的防晒护理。每2个月治疗1次,共治疗3次

干预措施代码:

Intervention:

Treatment is performed using the CO? fractional laser in DeepFX mode. After the procedure, a cold compress is applied topically, followed by routine sun protection care. The treatment is administered once every two months, for a total of three sessions.

Intervention code:

组别:

微型环钻术组

样本量:

47

Group:

B

Sample size:

干预措施:

根据瘢痕大小及厚度,选择直径大小合适的环钻(直径0.4-0.8mm),绷紧皮肤,将环钻垂直于瘢痕表面,旋转环钻并均匀用力,至钻透皮肤全层直到皮下脂肪层,用镊子提环钻的圆形柱状皮肤组织,局部压迫止血,确认创面无出血后外涂红霉素软膏,局部加压包扎,结束手术,共治疗1次。

干预措施代码:

Intervention:

Based on the size and thickness of the scar, a circular punch of appropriate diameter (0.4–0.8 mm) is selected. After the skin is stretched taut, the punch is positioned perpendicular to the scar surface. The punch is then rotated with steady and even pressure to penetrate the full thickness of the skin down to the subcutaneous fat layer. The resulting cylindrical skin tissue is lifted with forceps, and local pressure is applied to achieve hemostasis. Once bleeding is controlled, erythromycin ointment is applied to the wound surface, followed by localized pressure dressing. The procedure is completed in a single treatment session.
